Package groovy.lang

Core Groovy language classes for implementing data structures, closures, metadata and so forth.

  • Interface Summary 
    Interface Description
    AdaptingMetaClass
    An interface for MetaClass instances that "adapt" other MetaClass instances such as a proxy or delegating MetaClass.
    Buildable  
    ClosureInvokingMethod
    An interface for MetaMethods that invoke closures to implements.
    GeneratedGroovyProxy
    An interface implemented by some Groovy proxies which gives access to the proxied object.
    GroovyCallable<V>
    A special "marker" style interface allowing Groovy classes to implement both Runnable and Callable yet give preference to Runnable (for backwards compatibility) for APIs having both Runnable and Callable methods.
    GroovyInterceptable
    Marker interface used to notify that all methods should be intercepted through the invokeMethod mechanism of GroovyObject.
    GroovyObject
    The interface implemented by all Groovy objects.
    GroovyResourceLoader
    Allows frameworks that integrate with Groovy to determine how Groovy files are resolved.
    Interceptor
    Implementers of this interface can be registered in the ProxyMetaClass for notifications about method calls for objects managed by the ProxyMetaClass.
    MetaClass
    A MetaClass within Groovy defines the behaviour of any given Groovy or Java class.
    MetaClassRegistry
    A MetaClassRegistry is an object that is responsible for managing the a cache of MetaClass instances.
    MetaClassRegistryChangeEventListener
    A listener called whenever a constant MetaClass is set, removed or replaced.
    MetaObjectProtocol
    An interface that defines the API usable by clients of Groovy's Meta Object Protocol (MOP).
    MutableMetaClass
    An interface that defines methods that implementers of mutable Meta classes should specify.
    PropertyAccessInterceptor
    An interface that adds the ability to intercept property getters/setters
    Range<T extends Comparable>
    A Range represents the list of discrete items between some starting (or from) value and working up towards some ending (or to) value.
    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.

    Class Description

  • Annotation Types Summary 
    Annotation Type Description
    Category
    Transforms an instance-style Groovy class or interface to become a static-style conventional Groovy category.
    Delegate
    Annotation to automatically delegate part of the functionality of an owner class to the annotated delegation target.
    DelegatesTo
    This annotation can be used by API or DSL writers to document parameters which accept a closure.
    DelegatesTo.Target
    Parameter annotation used to specify the delegate for a @DelegatesTo annotated parameter of the same method.
    Grab
    Used to grab the referenced artifact and its dependencies and make it available on the Classpath.
    GrabConfig
    Used to modify the grape configuration for grab requests.
    GrabExclude
    Used to exclude an indirectly referenced artifact (a transitive dependency) from the classpath.
    GrabResolver
    Used to add a repository for resolving Grape dependencies.
    Grapes
    Sometimes we will need more than one grab per class, but we can only add one annotation type per annotatable node.
    Groovydoc
    An annotation to hold the groovydoc for the annotated element at runtime, we call it "Runtime Groovydoc".
    Lazy
    Field annotation to simplify lazy initialization.
    Mixin Deprecated.
    static mixins have been deprecated in favour of traits (trait keyword).
    Newify
    Annotation that supports writing constructor call expressions without the 'new' keyword.
    Singleton
    Class annotation to make a singleton class.
