### Constructor Detail

#### FilterSet

    public FilterSet()

Default constructor.

#### FilterSet

    protected FilterSet(FilterSet filterset)

Create a Filterset from another filterset.

Parameters:
  `filterset` - the filterset upon which this filterset will be based.

### Method Detail

#### getFilters

    protected java.util.Vector getFilters()

Get the filters in the filter set.

Returns:
  a Vector of Filter instances.

#### getRef

    protected FilterSet getRef()

Get the referenced filter set.

Returns:
  the filterset from the reference.

#### getFilterHash

    public java.util.Hashtable getFilterHash()

Gets the filter hash of the FilterSet.

Returns:
  The hash of the tokens and values for quick lookup.

#### setFiltersfile

    public void setFiltersfile(java.io.File filtersFile)
                        throws BuildException

Set the file containing the filters for this filterset.

Parameters:
  `filtersFile` - sets the filter file from which to read filters for this filter set.
Throws:
  `BuildException` - if there is an error.

#### setBeginToken

    public void setBeginToken(java.lang.String startOfToken)

Set the string used to id the beginning of a token.

Parameters:
  `startOfToken` - The new Begintoken value.

#### getBeginToken

    public java.lang.String getBeginToken()

Get the begin token for this filterset.

Returns:
  the filter set's begin token for filtering.

#### setEndToken

    public void setEndToken(java.lang.String endOfToken)

Set the string used to id the end of a token.

Parameters:
  `endOfToken` - The new Endtoken value.

#### getEndToken

    public java.lang.String getEndToken()

Get the end token for this filterset.

Returns:
  the filter set's end token for replacement delimiting.

#### setRecurse

    public void setRecurse(boolean recurse)

Set whether recursive token expansion is enabled.

Parameters:
  `recurse` - `boolean` whether to recurse.

#### isRecurse

    public boolean isRecurse()

Get whether recursive token expansion is enabled.

Returns:
  `boolean` whether enabled.

#### readFiltersFromFile

    public void readFiltersFromFile(java.io.File filtersFile)

Read the filters from the given file.

Parameters:
  `filtersFile` - the file from which filters are read.
Throws:
  `BuildException` - when the file cannot be read.

#### replaceTokens

    public java.lang.String replaceTokens(java.lang.String line)

Does replacement on the given string with token matching. This uses the defined begintoken and endtoken values which default to @ for both. This resets the passedTokens and calls iReplaceTokens to do the actual replacements.

Parameters:

Returns:
  The input string after token replacement.

Create a new FiltersFile.

Returns:
  The filtersfile that was created.

#### addFilter

    public void addFilter(java.lang.String token,
                 java.lang.String value)

Add a new filter made from the given token and value.

Parameters:
  `token` - The token for the new filter.
  `value` - The value for the new filter.

#### addConfiguredFilterSet

    public void addConfiguredFilterSet(FilterSet filterSet)

Add a Filterset to this filter set.

Parameters:
  `filterSet` - the filterset to be added to this filterset

#### hasFilters

    public boolean hasFilters()

Test to see if this filter set has filters.

Returns:

Overrides:
  `clone` in class `DataType`
Returns:
  a deep clone of this filterset.
Throws:
  `BuildException` - if the clone cannot be performed.

#### setOnMissingFiltersFile

    public void setOnMissingFiltersFile(FilterSet.OnMissing onMissingFiltersFile)

Set the behavior WRT missing filtersfiles.

Parameters:
  `onMissingFiltersFile` - the OnMissing describing the behavior.

#### getOnMissingFiltersFile

    public FilterSet.OnMissing getOnMissingFiltersFile()
