# Package org.apache.xml.utils

Implementation of Xalan utility classes.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  DOMOrder | Deprecated Since the introduction of the DTM, this class will be removed.
  NodeConsumer | The tree walker will test for this interface, and call setOriginatingNode before calling the SAX event.
  PrefixResolver | The class that implements this interface can resolve prefixes to namespaces.
  RawCharacterHandler | An interface that a Serializer/ContentHandler/ContentHandler must implement in order for disable-output-escaping to work.
  XMLString | This class is meant to be an interface to character strings, whether they be java Strings or `org.apache.xml.utils.FastStringBuffer`s, or other character data.

- Class Summary
  Class | Description
  --- | ---
  AttList | Wraps a DOM attribute list in a SAX Attributes.
  BoolStack | Simple stack for boolean values.
  Constants | Primary constants used by the XSLT Processor
  DefaultErrorHandler | Implement SAX error handler for default reporting.
  DOM2Helper | Deprecated Since the introduction of the DTM, this class will be removed.
  DOMBuilder | This class takes SAX events (in addition to some extra events that SAX doesn't handle yet) and adds the result to a document or document fragment.
  DOMHelper | Deprecated Since the introduction of the DTM, this class will be removed.
  FastStringBuffer | Bare-bones, unsafe, fast string buffer.
  Hashtree2Node | Simple static utility to convert Hashtable to a Node.
  IntStack | Implement a stack of simple integers.
  IntVector | A very simple table that stores a list of int.
  ListingErrorHandler | Sample implementation of similar SAX ErrorHandler and JAXP ErrorListener.
  LocaleUtility |
  MutableAttrListImpl | Mutable version of AttributesImpl.
  NameSpace | A representation of a namespace.
  NamespaceSupport2 | Encapsulate Namespace tracking logic for use by SAX drivers.
  NodeVector | A very simple table that stores a list of Nodes.
  NSInfo | This class holds information about the namespace info of a node.
  ObjectPool | Pool of object of a given type to pick from to help memory usage
  ObjectStack | Implement a stack of simple integers.
  ObjectVector | A very simple table that stores a list of objects.
  PrefixResolverDefault | This class implements a generic PrefixResolver that can be used to perform prefix-to-namespace lookup for the XPath object.
  QName | Class to represent a qualified name: "The name of an internal XSLT object, specifically a named template (see [7 Named Templates]), a mode (see [6.7 Modes]), an attribute set (see [8.1.4 Named Attribute Sets]), a key (see [14.2 Keys]), a locale (see [14.3 Number Formatting]), a variable or a parameter (see [12 Variables and Parameters]) is specified as a QName.
  SAXSourceLocator | Class SAXSourceLocator extends org.xml.sax.helpers.LocatorImpl for the purpose of implementing the SourceLocator interface, and thus can be both a SourceLocator and a SAX Locator.
  SerializableLocatorImpl | The standard SAX implementation of LocatorImpl is not serializable, limiting its utility as "a persistent snapshot of a locator".
  StringBufferPool | This class pools string buffers, since they are reused so often.
  StringComparable | International friendly string comparison with case-order
  StringToIntTable | A very simple lookup table that stores a list of strings, the even number strings being keys, and the odd number strings being values.
  StringToStringTable | A very simple lookup table that stores a list of strings, the even number strings being keys, and the odd number strings being values.
  StringToStringTableVector | A very simple table that stores a list of StringToStringTables, optimized for small lists.
  StringVector | A very simple table that stores a list of strings, optimized for small lists.
  StylesheetPIHandler | Search for the xml-stylesheet processing instructions in an XML document.
  SuballocatedByteVector | A very simple table that stores a list of byte.
  SuballocatedIntVector | A very simple table that stores a list of int.
  SystemIDResolver | This class is used to resolve relative URIs and SystemID strings into absolute URIs.
  ThreadControllerWrapper | A utility class that wraps the ThreadController, which is used by IncrementalSAXSource for the incremental building of DTM.
  ThreadControllerWrapper.ThreadController | Thread controller utility class for incremental SAX source.
  TreeWalker | This class does a pre-order walk of the DOM tree, calling a ContentHandler interface as it goes.
  UnImplNode | To be subclassed by classes that wish to fake being nodes.
  URI | A class to represent a Uniform Resource Identifier (URI).
  XML11Char | THIS IS A COPY OF THE XERCES-2J CLASS org.apache.xerces.utls.XMLChar This class defines the basic properties of characters in XML 1.1.
  XMLChar | This class defines the basic XML character properties.
  XMLCharacterRecognizer | Class used to verify whether the specified ch conforms to the XML 1.0 definition of whitespace.
  XMLReaderManager | Creates XMLReader objects and caches them for re-use.
  XMLStringDefault | The default implementation of the XMLString interface, which is just a simple wrapper of a String object.
  XMLStringFactory | A concrete class that implements this interface creates XMLString objects.
  XMLStringFactoryDefault | The default implementation of XMLStringFactory.

- Exception Summary
  Exception | Description
  --- | ---
  StopParseException | This is a special exception that is used to stop parsing when search for an element.
  URI.MalformedURIException | MalformedURIExceptions are thrown in the process of building a URI or setting fields on a URI when an operation would result in an invalid URI specification.
  WrappedRuntimeException | This class is for throwing important checked exceptions over non-checked methods.
  WrongParserException | Certain functions may throw this error if they are paired with the incorrect parser.

## Package org.apache.xml.utils Description

Implementation of Xalan utility classes. This package is also shared by XPath. There *should* be no outward dependencies to XPath or Xalan by classes in this package.
