Package org.apache.uima.util

Utility classes and interfaces used by UIMA components.

Interface Summary

Interface	Description
CasPoolManagement	Management interface to a CasPool.
InstrumentationFacility	The InstrumentationFacility interface defines a standard way for UIMA components to be instrumented for performance evaluation.
Logger	A Logger is a component used to log messages.
ProcessTrace	A ProcessTrace object keeps a record of events that have occurred and information, such as timing, about those events.
ProcessTraceEvent	Captures information, including timing, about an event that occurred during processing.
Progress	Progress statistics for a process.
SaxDeserializer	Deserializes an XMLizable object from SAX events.
Settings	A Settings object holds the properties used for external parameter overrides.
TCasFormatter	Interface for components that generate a String representation of a CAS.
UimaTimer	Interface for a timer, used to collect performance statistics for UIMA components.
XMLizable	An interface to be implemented by UIMA classes that can be written to and parsed from XML.
XMLParser	A UIMA XMLParser parses XML documents and generates UIMA components represented by the XML.

Class Summary

Class	Description
AnalysisEnginePerformanceReports	A class that is useful for generating an Analysis Engine performance report from a ProcessTrace object.
AnalysisEngineUtils	Static utility methods relating to analysis engines.
CasCopier	Utility class for doing deep copies of FeatureStructures from one CAS to another.
CasCreationUtils	Utilities for creating and setting up CASes.
CasIOUtils	A collection of static methods aimed at making it easy to
CasPool	This class represents a simple pool of CAS instances.
CasToInlineXml	Generates an *approximate* inline XML representation of a CAS.
ConcurrentHashMapWithProducer<K,V>	A concurrent map supporting a value-creating get.
ConsumerCasUtils
FileUtils	Some utilities for handling files.
JCasPool	This class represents a simple pool of JCas instances.
Level	Provides the message level constants for logging and tracing
LoggerPrintStream	A PrintStream implementation that writes to a UIMA logger.
MessageReport
Misc
NameClassPair	A class that stores the name of an attribute and the Class of that attribute's value.
ProgressImpl
SimpleResourceFactory	A simple implementation of a ResourceFactory.
TCasToInlineXml	Deprecated. As of v2.0, use CasToInlineXml instead.
TypeSystemUtil
UriUtils	Static methods supporting proper handling of URIs
XmlCasDeserializer	Deserializes a CAS from a standoff-XML format.
XmlCasSerializer	This class is an older class with just two static methods which forward to methods in XmiCasSerializer.
XMLInputSource	An input source used by the XMLParser to read XML documents for parsing.
XMLParser.ParsingOptions	Option settings for the parser.
XMLSerializer	Utility class that generates XML output from SAX events or DOM nodes.

Enum Summary

Enum	Description
CasLoadMode	Used with CasIOUtils, maybe elsewhere, to indicate how CASes are to be loaded or saved.

Exception Summary

Exception	Description
InvalidXMLException	Thrown by the XMLParser to indicate that an XML document is invalid or does not specify a valid object of the desired class.
