  - ### Method Detail

    - #### getConfigParameterValue

          public Object getConfigParameterValue(String aName)

      Description copied from interface: `AnnotatorContext`
      Retrieves the value for a configuration parameter that is not defined in any group or is defined in the default group.

      This method returns `null` if the parameter is optional and has not been assigned a value. (For mandatory parameters, an exception is thrown during initialization if no value has been assigned.) This method also returns `null` if there is no declared configuration parameter with the specified name.

      Specified by:
        `getConfigParameterValue` in interface `AnnotatorContext`
      Parameters:
        `aName` - the name of the parameter to look up
      Returns:
        the value of the parameter with the given name. The annotator is expected to know the data type of its parameters. Returns `null` if the parameter does not exist or has not been assigned a value.
      See Also:
        `AnnotatorContext.getConfigParameterValue(String)`

    - #### getConfigParameterValue

      Description copied from interface: `AnnotatorContext`
      Retrieves the value for a configuration parameter in a particular group. If that group contains no value for the specified parameter, the fallback strategy specified by the Analysis Engine's `ConfigurationParameterDeclarations.getSearchStrategy()` property will be used. The search strategy can be specified in the Analysis Engine Descriptor.

      This method returns `null` if the parameter is optional and has not been assigned a value. (For mandatory parameters, an exception is thrown during initialization if no value has been assigned.) This method also returns `null` if there is no declared configuration parameter with the specified name.

      Specified by:
        `getConfigParameterValue` in interface `AnnotatorContext`
      Parameters:
        `aGroupName` - the name of the group containing the parameter
        `aParamName` - the name of the parameter to look up
      Returns:
        the value of the parameter with the given name. The annotator is expected to know the data type of its parameters. Returns `null` if the parameter does not exist or has not been assigned a value.
      See Also:
        `AnnotatorContext.getConfigParameterValue(java.lang.String, java.lang.String)`

    - #### getLogger

      Returns:
        an array containing the names of all configuration parameters declared in {`aGroup`. Note that this does include parameters with null values. Returns an empty array if there are none (including if the group does not exist).

    - #### getResourceURL

          public URL getResourceURL(String aKey)
                             throws AnnotatorContextException

      Locates Resource URL's using the ResourceManager, or, if that fails, the ClassLoader.
      Specified by:
        `getResourceURL` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should be declared in the <externalResourceDependencies> section of the descriptor.
      Returns:
        the `URL` at which the named resource is located, `null` if the named resource could not be found.
      Throws:
        `AnnotatorContextException` - if there's a problem
      See Also:
        `AnnotatorContext.getResourceURL(String)`

    - #### getResourceURI

          public URI getResourceURI(String aKey)
                             throws AnnotatorContextException

      Description copied from interface: `AnnotatorContext`
      Retrieves the URI to the named resource. This can be used, for example, to locate configuration or authority files. The resource should be declared in the <externalResourceDependencies> section of the descriptor.

      This method is safer than `AnnotatorContext.getResourceURL(String)` in its treatment of file paths containing spaces. This is because the `URI.getPath()` does perform URL decoding of that path (decoding %20 sequences to spaces) whereas `URL.getPath()` does not.

      For backwards compatibility, if the key is not declared as a resource dependency, it is looked up directly in the `data path` and the class path. However, this usage is deprecated and support may be dropped in future versions. ALL external resource dependencies should be declared in the descriptor.

      Specified by:
        `getResourceURI` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should be declared in the <externalResourceDependencies> section of the descriptor.
      Returns:
        the `URI` at which the named resource is located, `null` if the named resource could not be found.
      Throws:
        `AnnotatorContextException` - if there's an exception
      See Also:
        `UimaContext.getResourceURI(String)`

    - #### getResourceFilePath

          public String getResourceFilePath(String aKey)
                                     throws AnnotatorContextException

      Description copied from interface: `AnnotatorContext`
      Retrieves the absolute file path to the named resource. This can be used, for example, to locate configuration or authority files. The resource should be declared in the <externalResourceDependencies> section of the descriptor.

      This only works if the resource is a local file. If the resource is not a local file (for example, it could be an `http` URL, then an exception will be thrown.

      URL decoding will be done on the file path, so it is safe to use this method for file paths that contain spaces. For backwards compatibility, if the key is not declared as a resource dependency, it is looked up directly in the `data path` and the class path. However, this usage is deprecated and support may be dropped in future versions. ALL external resource dependencies should be declared in the descriptor.

      Specified by:
        `getResourceFilePath` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should be declared in the <externalResourceDependencies> section of the descriptor.
      Returns:
        the absolute file path at which the named resource is located, `null` if the named resource could not be found.
      Throws:
        `AnnotatorContextException` - if there's an exception
      See Also:
        `UimaContext.getResourceFilePath(String)`

    - #### getResourceAsStream

          public InputStream getResourceAsStream(String aKey)
                                          throws AnnotatorContextException

      Acquires Resource InputStreams using the ResourceManager, or, if that fails, the ClassLoader.
      Specified by:
        `getResourceAsStream` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should be declared in the <externalResourceDependencies> section of the descriptor.
      Returns:
        an `InputStream` for reading from the named resource, `null` if the named resource could not be found. It is the caller's responsibility to close this stream once it is no longer needed.
      Throws:
        `AnnotatorContextException` - if an error occurs
      See Also:
        `AnnotatorContext.getResourceAsStream(String)`

    - #### getResourceObject

          public Object getResourceObject(String aKey)

      Specified by:
        `getResourceObject` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should be declared in the <externalResourceDependencies> section of the descriptor.
      Returns:
        the object bound to `aName`, `null` if none.
      Throws:
        `AnnotatorContextException` - if an error occurs

        `AnnotatorContext.getResourceObject(String)`

    - #### getResourceAsStream

          public InputStream getResourceAsStream(String aKey,
                                                 String[] aParams)
                                          throws AnnotatorContextException

      Description copied from interface: `AnnotatorContext`
      Retrieves an InputStream for reading from the named resource. This can be used, for example, to locate configuration or authority files. The resource should be declared in the <externalResourceDependencies> section of the descriptor.

      For backwards compatibility, if the key is not declared as a resource dependency, it is looked up directly in the `data path` and the class path. However, this usage is deprecated and support may be dropped in future versions. ALL external resource dependencies should be declared in the descriptor.

      This version of this method takes an array of parameters used to further identify the resource. This can be used, for example, with resources that vary depending on the language of the document being analyzed, such as when the <fileLanguageResourceSpecifier> element is used in the component descriptor.

      Specified by:
        `getResourceAsStream` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should bd declared in the <externalResourceDependencies> section of the descriptor.
        `aParams` - parameters used to further identify the resource. When used to identify the language for a <fileLanguageResourceSpecifier>, this array should contain a single element, the ISO language code for the language of the document (e.g. "en", "de").
      Returns:
        an `InputStream` for reading from the named resource, `null` if the named resource could not be found. It is the caller's responsibility to close this stream once it is no longer needed.
      Throws:
        `AnnotatorContextException` - if an error occurs
      See Also:
        `AnnotatorContext.getResourceAsStream(java.lang.String, java.lang.String[])`

          public Object getResourceObject(String aKey,
                                          String[] aParams)
                                   throws AnnotatorContextException

      Description copied from interface: `AnnotatorContext`
      Retrieves the named resource object. This can be used to acquire references to external resources. The resource should be declared in the <externalResourceDependencies> section of the descriptor.

      This version of this method takes an array of parameters used to further identify the resource. This can be used, for example, with resources that vary depending on the language of the document being analyzed, such as when the <fileLanguageResourceSpecifier> element is used in the component descriptor.

      Specified by:
        `getResourceObject` in interface `AnnotatorContext`
      Parameters:
        `aKey` - the key by which the resource is identified. This key should be declared in the <externalResourceDependencies> section of the descriptor.
        `aParams` - parameters used to further identify the resource. When used to identify the language for a <fileLanguageResourceSpecifier>, this array should contain a single element, the ISO language code for the language of the document (e.g. "en", "de").
      Returns:
        the object bound to `aName`, `null` if none.
      Throws:

      Description copied from interface: `AnnotatorContext`
      Retrieves the URL to the named resource. This can be used, for example, to locate configuration or authority files. The resource should be declared in the <externalResourceDependencies> section of the descriptor.

      Note that if the URL contains spaces may be encoded as %20. The `URL.getPath()` method does NOT decode these sequences, therefore it is not safe to call `getResourceURL().getPath()` and attempt to use the result as a file path. Instead, you may use `AnnotatorContext.getResourceURI(String)` or `AnnotatorContext.getResourceFilePath(String)`.

      For backwards compatibility, if the key is not declared as a resource dependency, it is looked up directly in the `data path` and the class path. However, this usage is deprecated and support may be dropped in future versions. ALL external resource dependencies should be declared in the descriptor.
