Interface Summary
Buildable  
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 which is handy for using Groovy objects when in the Java world
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.
Range Represents the interface of a Range implementation which includes the from and to values
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 Summary
BenchmarkInterceptor Interceptor that registers the timestamp of each method call before and after invocation.
Binding 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.
Closure Represents any closure object in Groovy.
DelegatingMetaClass  
EmptyRange Constructing Ranges like 0..<0
GroovyClassLoader A ClassLoader which can load Groovy classes.
GroovyClassLoader.ClassCollector  
GroovyClassLoader.InnerLoader  
GroovyCodeSource CodeSource wrapper class that allows specific security policies to be associated with a class compiled from groovy source.
GroovyObjectSupport A useful base class for Java objects wishing to be Groovy objects
GroovyShell Represents a groovy shell capable of running arbitrary groovy scripts
GString Represents a String which contains embedded values such as "hello there ${user} how are you?" which can be evaluated lazily.
IntRange Represents a list of Integer objects from a specified int up to and including a given and to.
MetaArrayLengthProperty Represents a property on a bean which may have a getter and/or a setter
MetaBeanProperty Represents a property on a bean which may have a getter and/or a setter
MetaClass Base class for meta class implementations.
MetaClassImpl Allows methods to be dynamically added to existing classes at runtime
MetaClassRegistry A registery of MetaClass instances which caches introspection & reflection information and allows methods to be dynamically added to existing classes at runtime
MetaExpandoProperty Represents a property in an Expando object
MetaFieldProperty Represents a property on a bean which may have a getter and/or a setter
MetaMethod Represents a Method on a Java object a little like Method except without using reflection to invoke the method
MetaProperty Represents a property on a bean which may have a getter and/or a setter
NonEmptySequence Represents a sequence of objects which represents one or many instances of of objects of a given type.
ObjectRange Represents an inclusive list of objects from a value to a value using comparators
ParameterArray Distinguish a parameter array from Object[].
PropertyValue  
ProxyMetaClass As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs.
Reference Represents a reference to a value
Script This object represents a Groovy script
Sequence Represents a sequence of objects which represents zero or many instances of of objects of a given type.
SpreadMap Represents a spreadable map which extends java.util.HashMap.
TracingInterceptor  
Tuple Represents a list of Integer objects from a specified int up to but not including a given and to.
 

Exception Summary
BitwiseNegateEvaluatingException  
ClosureException An exception thrown by a closure invocation
DeprecationException Use this exception to mark a method implementation as being deprecated.
GroovyRuntimeException An exception thrown by the interpreter
IllegalPropertyAccessException An exception occurred if a dynamic property dispatch fails with a field not accessible.
IncorrectClosureArgumentsException An exception occurred when invoking a Closure with the wrong number and/or types of arguments
MissingClassException An exception occurred if a dynamic method dispatch fails with an unknown class.
MissingFieldException An exception occurred if a dynamic field dispatch fails with an unknown field.
MissingMethodException An exception occurred if a dynamic method dispatch fails with an unknown method.
MissingPropertyException An exception occurred if a dynamic property dispatch fails with an unknown property.
ReadOnlyPropertyException This exception is thrown if an attempt is made to set a read only property
SpreadListEvaluatingException  
SpreadMapEvaluatingException  
StringWriterIOException An IO exception occurred trying to append to a StringWriter which should never happen.
