Interface Summary

Interface	Description
AnnotationDiffer.Pairing	Interface representing a pairing between a key annotation and a response one.
Benchmarkable	Resources that want to log their progress or results into a shared log centrally maintained by GATE, should implement this interface and use the java.util.Benchmark class to log their entries.
ClosableIterator<T>	An iterator that should be closed as soon as it is not used anymore.
DocumentProcessor	Very simple interface for a component that processes GATE documents.
FeatureBearer	Classes whose instances each have a FeatureMap.
IdBearer	Classes that have Ids.
NameBearer	Classes whose instances each have a name.
ThreadWarningSystem.Listener	This is called whenever a problem with threads is detected.

Class Summary

Class	Description
AbstractFeatureBearer	A convenience implemetation of FeatureBearer.
AbstractNameBearer
AnnotationDiffer	This class provides the logic used by the Annotation Diff tool.
AnnotationDiffer.PairingOffsetComparator	Compares two choices based on start offset of key (or response if key not present) and type if offsets are equal.
AnnotationDiffer.PairingScoreComparator	Compares two pairings: the better score is preferred; for the same score the better type is preferred (exact matches are preffered to partial ones).
AnnotationMerging	Merging the annotations from different annotators.
Benchmark	This class provides methods for making entries in the shared log maintained by the GATE system.
BomStrippingInputStreamReader	StreamReader that removes the Unicode BOM, even when Sun/Oracle is too lazy to do so.
ClassificationMeasures	Given two annotation sets, a type and a feature, compares the feature values.
CorpusBenchmarkTool
CreoleXmlUpperCaseFilter	SAX XMLFilter implementation used when reading a creole.xml file to ensure that all the standard creole elements and their attribute names are converted to upper case.
Err	Shorthand for the System.err.print and println methods.
ExtensionFileFilter	Implementation of a file name filter.
Files	Some utilities for use with Files and with resources.
GateClassLoader	GATE's class loader, which allows loading of classes over the net.
HashMapLong	simple cut-off version of the hashmap with native long's as keys only get,put and isEmpty methods are implemented().
Javac	This class compiles a set of java sources using the user's preferred Java compiler.
LanguageAnalyserDocumentProcessor	DocumentProcessor that processes documents using a LanguageAnalyser.
NameComparator	Compares NameBearers by name (string comparation)
ObjectComparator	A Comparator implementation for Object values.
ObjectPool	A generic implementation of pool of references to objects of any kind.
ObjectWriter	Writes an object to an PipedOutputStream wich can be connected to a PipedInputStream.
OffsetComparator	Compares annotations by start offsets first, then by end offset if the start offsets are equal.
OntologyMeasures	Modified version of Precision and Recall called BDM that takes into account the distance of two concepts in an ontology.
OptionsMap	A map that stores values as strings and provides support for converting some frequently used types to and from string. Not very efficient as there is a lot of conversions from/to String.
OrderByRestriction
Out	Shorthand for the System.out.print and println methods.
Pair
ProcessManager	Class that supports running an external process and either silently consuming its standard output and error streams, or copying them to Java's stdout and stderr.
RawEditorKit	This class provides an editor kit that does not change \n\r to \n but instead it leaves the original text as is.
RBTreeMap<K,V>	Slightly modified implementation of java.util.TreeMap in order to return the closest neighbours in the case of a failed search.
SimpleArraySet<T>	A specific *partial* implementation of the Set interface used for high performance and memory reduction on small sets.
SimpleFeatureMapImpl	Simple case of features.
SimpleSortedSet	The purpose of this Map is to combine the functionality found in TreeSet, especially first() and tailSet() with the hashcode driven map using native long as key to hold the annotations ordered by their offset.
Strings	Some utilities for use with Strings.
ThreadWarningSystem	http://www.javaspecialists.eu/archive/Issue093.html
Tools
VersionComparator	A comparator that can be used for comparing GATE version strings.

Exception Summary

Exception	Description
DocumentFormatException	This exception can be used to catch any internal exception thrown by the DocumentFormat class and its subbclasses.
GateException	A superclass for exceptions in the GATE packages.
GateRuntimeException	Exception used to signal a runtime exception within Gate.
GateSaxException	An inherited class from SAX exception in the GATE packages.
InvalidOffsetException	Used to signal an attempt to create a node with an invalid offset.
LuckyException	Deprecated serves no purpose over and above either GateRuntimeException or just plain RuntimeException and one of those should be used instead.
MethodNotImplementedException	What to throw in a method that hasn't been implemented yet.
