Verifier.DefaultArgsAction
Strategy invoked for each synthetic method or constructor generated for default arguments.
VerifierCodeVisitor
Performs various checks on code inside methods and constructors including checking for valid field, variables names etc.
VerifyClass
Verify Class files.
Vetoable
Annotates a groovy property or a class.
VetoableASTStubber
Joint-compilation stubber for `Vetoable` (class-level use).
VetoableASTTransformation
Handles generation of code for the `@Vetoable` annotation, and `@Bindable` if also present.
ViolationTracker
A violation tracker is used to keep a list of pre-, post-condition or class-invariant violations in chronological order.
Virtual
Marks a public trait `static` method as virtual: trait-body calls to this method dispatch through the implementing class at runtime, so a same-signature static method declared on the implementing class overrides the trait's default.
Visibility
Indicates the visibility of a node.
VisibilityOptions
Marker annotation used in the context of AST transformations to provide a custom visibility.
VisibilityUtils
Utility methods for resolving visibility customizations from `VisibilityOptions`.
VMPlugin
Interface to access VM version based actions.
VMPluginFactory
Factory class to get functionality based on the VM version.
WarningMessage
A class for warning messages.
Weigher<V>
A class that can determine the weight of a value.
Weighers
A common set of `Weigher` and `EntryWeigher` implementations.
WhereExpression
Represent the where expression
WhileStatement
Represents a while (condition) { ...
WideningCategories
This class provides helper methods to determine the type from a widening operation for example for a plus operation.
WideningCategories.LowestUpperBoundClassNode
This `ClassNode` specialization is used when the lowest upper bound of two types cannot be represented by an existing type.
Window<T>
Represents window which stores elements used by window functions
WindowDefinition<T,U extends Comparable<? super U>>
Represents window definition, which will define the result set to construct the window
WithReadLock
This annotation is used in conjunction with `WithWriteLock` to support read and write synchronization on a method.
WithWriteLock
This annotation is used in conjunction with `WithReadLock` to support read and write synchronization on a method.
Wrapper
Base class for runtime wrappers that expose a value through `GroovyObject` while reporting a constrained type.
Writable
Represents an object which is capable of writing itself to a text stream in a more efficient format than just creating a toString() representation of itself.
WritableFile
A file wrapper implementing the `Writable` interface to support writing file contents.
WritablePath
`Path` wrapper that also implements `Writable`.
WriterController
Central coordinator for Groovy-to-bytecode compilation of a single class.
WriterControllerFactory
A non-static factory to get alternative writer controller to be stored in the metadata
XmlExtensions
This class defines all the new XML-related groovy methods which enhance the normal JDK XML classes when inside the Groovy environment.
XmlNodePrinter
Prints a `groovy.util.Node` (as used with `XmlParser`) including all children in XML format.
XmlNodePrinter.NamespaceContext
Tracks namespace declarations already emitted while printing a subtree.
XmlParser
A helper class for parsing XML into a tree of Node instances for a simple way of processing XML.
XmlRuntimeException
Represents a runtime exception that occurred when parsing or building XML.
XmlSlurper
Parse XML into a document tree that may be traversed similar to XPath expressions.
XmlTemplateEngine
Template engine for use in templating scenarios where both the template source and the expected output are intended to be XML.
XmlUtil
Used for pretty printing XML content and other XML related utilities.
XStreamUtils
Serializes AST structures to XML for debugging.
YamlBuilder
A builder for creating YAML payloads.
YamlConverter
A converter for converting YAML to JSON, vice versa
YamlRuntimeException
Represents a runtime exception raised while parsing or building YAML.
YamlSlurper
Represents a YAML parser
YieldStatement
Represents a `yield` statement that produces the value of an enclosing `SwitchExpression`.
