package groovy.lang

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

  • Interface Summary
    Interface
    Description
    An interface for MetaClass instances that "adapt" other MetaClass instances such as a proxy or delegating MetaClass.
     
    An interface for MetaMethods that invoke closures to implements.
    An interface implemented by some Groovy proxies which gives access to the proxied object.
    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.
    Marker interface used to notify that all methods should be intercepted through the invokeMethod mechanism of GroovyObject.
    The interface implemented by all Groovy objects.
    Allows frameworks that integrate with Groovy to determine how Groovy files are resolved.
    Implementers of this interface can be registered in the ProxyMetaClass for notifications about method calls for objects managed by the ProxyMetaClass.
    A MetaClass within Groovy defines the behaviour of any given Groovy or Java class.
    A MetaClassRegistry is an object that is responsible for managing the a cache of MetaClass instances.
    A listener called whenever a constant MetaClass is set, removed or replaced.
    An interface that defines the API usable by clients of Groovy's Meta Object Protocol (MOP).
    An interface that defines methods that implementers of mutable Meta classes should specify.
    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.
    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 Summary
    Class
    Description
    Interceptor that registers the timestamp of each method call before and after invocation.
    Represents the variable bindings of a script which can be altered from outside the script object or created outside of a script and passed into it.
    Represents any closure object in Groovy.
     
    Constructing Ranges like 0..<0
    ExpandoMetaClass is a MetaClass that behaves like an Expando, allowing the addition or replacement of methods, properties and constructors on the fly.
    A handle for the MetaClassRegistry that changes all classes loaded into the Grails VM to use ExpandoMetaClass instances
    A ClassLoader which can load Groovy classes.
     
     
    CodeSource wrapper class that allows specific security policies to be associated with a class compiled from groovy source.
    Base class for Java objects wishing to be Groovy objects.
    Represents a groovy shell capable of running arbitrary groovy scripts
     
    Represents a String which contains embedded values such as "hello there ${user} how are you?" which can be evaluated lazily.
    Represents a list of Integer objects starting at and potentially including a specified from value up (or down) to and potentially including a given to value.
    A wrapper for List which automatically grows the list when either ListWithDefault.get(int) or ListWithDefault.getAt(int) is called with an index greater than or equal to size().
    A wrapper for Map which allows a default value to be specified.
    Represents the length property of an array
    Represents a property on a bean which may have a getter and/or a setter
    Allows methods to be dynamically added to existing classes at runtime
    Deprecated.
    use LinkedHashMap instead
    This is a helper class introduced in Groovy 2.1.0, which is used only by indy.
    Class used as base for the creation of MetaClass implementations.
    An event used to propagate meta class updates
    Represents a property in an Expando object
    Represents a Method on a Java object a little like Method except without using reflection to invoke the method
    Represents a property on a bean which may have a getter and/or a setter
    Represents a sequence of one or more objects of a given type.
    Represents an immutable list of Numbers from a value to a value with a particular step size.
    Represents an inclusive list of objects from a value to a value using comparators.
     
    As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs.
    Represents a reference to a value
    This object represents a Groovy script
    Represents a sequence of zero or more objects of a given type.
    Helper to turn a list with an even number of elements into a Map.

    An exception occurred if a dynamic field dispatch fails with an unknown field.
    An exception occurred if a dynamic method dispatch fails with an unknown method.
    An exception occurred if a dynamic property dispatch fails with an unknown property.
    This exception is thrown if an attempt is made to set a read only property

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