# Package org.codehaus.groovy.runtime

Runtime classes for Groovy - whether the dynamic interpreter is being used, the compiler or the bytecode generator.

- Interface Summary
  Interface | Description
  --- | ---
  GeneratedClosure | Marker interface to identify closures generated by the groovy compiler.
  GeneratedLambda | Marker interface to identify lambda generated by the groovy compiler.

- Class Summary
  Class | Description
  --- | ---
  AbstractComparator<T> |
  ArrayTypeUtils | Utilities for handling array types
  ArrayUtil | This is a generated class used internally during the writing of bytecode within the CallSiteWriter logic.
  BytecodeInterface8 | This class contains methods special to optimizations used directly from bytecode in Groovy 1.8
  ComposedClosure<V> | A wrapper for Closure to support composition.
  ConversionHandler | This class is a general adapter to map a call to a Java interface to a given delegate.
  ConvertedClosure | This class is a general adapter to adapt a closure to any Java interface.
  ConvertedMap | This class is a general adapter to adapt a map of closures to any Java interface.
  CurriedClosure<V> | A wrapper for Closure to support currying.
  DateGroovyMethods | Deprecated. use DateUtilExtensions instead
  DefaultCachedMethodKey | A default implementation of MethodKey
  DefaultGroovyMethods | This class defines new groovy methods which appear on normal JDK classes inside the Groovy environment.
  DefaultGroovyMethodsSupport | Support methods for DefaultGroovyMethods and PluginDefaultMethods.
  DefaultGroovyStaticMethods | This class defines all the new static groovy methods which appear on normal JDK classes inside the Groovy environment.
  DefaultMethodKey | A default implementation of MethodKey
  EncodingGroovyMethods | This class defines all the encoding/decoding groovy methods which enhance the normal JDK classes when inside the Groovy environment.
  EncodingGroovyMethodsSupport | Keep this constant in a separate file as it is troublesome for Antlr to parse for doc purposes.
  FlushingStreamWriter | Stream writer which flushes after each write operation.
  GroovyCategorySupport | Support methods for Groovy category usage
  GroovyCategorySupport.CategoryMethod |
  GroovyCategorySupport.CategoryMethodList |
  GroovyCategorySupport.ThreadCategoryInfo |
  GStringImpl | Default implementation of a GString used by the compiler.
  HandleMetaClass |
  InvokerHelper | A static helper class to make bytecode generation easier and act as a facade over the Invoker
  IOGroovyMethods | This class defines new groovy methods for Files, URLs, URIs which appear on normal JDK classes inside the Groovy environment.
  IteratorClosureAdapter<T> | A closure which stores calls in a List so that method calls can be iterated over in a 'yield' style way
  MetaClassHelper |
  MethodClosure | Represents a method on an object using a closure which can be invoked at any time
  MethodKey | An abstract base class for a key used for comparators and Map keys to lookup a method by name and parameter types
  MethodRankHelper | Utility class for MissingMethodException, MissingPropertyException etc.
  NioGroovyMethods | Deprecated.
  NullObject |
  NumberAwareComparator<T> | Compares two objects using Groovy's friendly comparison algorithm, i.e.
  ProcessGroovyMethods | This class defines new groovy methods which appear on normal JDK classes related to process management.
  ProcessGroovyMethods.ProcessRunner | A Runnable which waits for a process to complete together with a notification scheme allowing another thread to wait a maximum number of seconds for the process to complete before killing it.
  ProxyGeneratorAdapter | A proxy generator responsible for mapping a map of closures to a class implementing a list of interfaces.
  RangeInfo |
  ReflectionMethodInvoker | Utility class to call methods through reflection, and falls through using the `Invoker` to call the method if it fails.
  Reflector | Provides as alternative to reflection using bytecode generation.
  RegexSupport | Used to store the last regex match.
  ResourceGroovyMethods | This class defines new groovy methods for Readers, Writers, InputStreams and OutputStreams which appear on normal JDK classes inside the Groovy environment.
  ReverseListIterator<T> | A reverse iterator over a list.
  ScriptBytecodeAdapter | A static helper class to interface bytecode and runtime
  ScriptReference | Represents a reference to a variable in a script
  ScriptTestAdapter | Deprecated. use `ScriptTestAdapter`
  SocketGroovyMethods | This class defines new groovy methods for Sockets which enhance JDK classes inside the Groovy environment.
  StackTraceUtils | Originally was grails.utils.GrailsUtils, removed some grails specific stuff.
  StringBufferWriter | This class codes around a silly limitation of StringWriter which doesn't allow a StringBuffer to be passed in as a constructor for some bizarre reason.
  StringGroovyMethods | This class defines new groovy methods which appear on String-related JDK classes (String, CharSequence, Matcher) inside the Groovy environment.
  SwingGroovyMethods | Deprecated.
  WritableFile | A Writable File.
  WritablePath | Deprecated.
  XmlGroovyMethods | Deprecated.
