Package org.apache.xpath

Implementation of XPath; for the most part, only classes meant for public use are found at this root level of the XPath packages.

Interface Summary

Interface	Description
ExpressionNode	A class that implements this interface can construct expressions, give information about child and parent expressions, and give the originating source information.
ExpressionOwner	Classes that implement this interface own an expression, which can be rewritten.
ExtensionsProvider	Interface that XPath objects can call to obtain access to an ExtensionsTable.
WhitespaceStrippingElementMatcher	A class that implements this interface can tell if a given element should strip whitespace nodes from it's children.
XPathFactory	Factory class for creating an XPath.
XPathVisitable	A class that implements this interface will call a XPathVisitor for itself and members within it's heararchy.

Class Summary

Class	Description
Arg	This class holds an instance of an argument on the stack.
CachedXPathAPI	The methods in this class are convenience methods into the low-level XPath API.
Expression	This abstract class serves as the base for all expression objects.
NodeSet	The NodeSet class can act as either a NodeVector, NodeList, or NodeIterator.
NodeSetDTM	The NodeSetDTM class can act as either a NodeVector, NodeList, or NodeIterator.
SourceTree	This object represents a Source Tree, and any associated information.
SourceTreeManager	This class bottlenecks all management of source trees.
VariableStack	Defines a class to keep track of a stack for template arguments and variables.
XPath	The XPath class wraps an expression object and provides general services for execution of that expression.
XPathAPI	The methods in this class are convenience methods into the low-level XPath API.
XPathContext	Default class for the runtime execution context for XPath.
XPathVisitor	A derivation from this class can be passed to a class that implements the XPathVisitable interface, to have the appropriate method called for each component of the XPath.

Exception Summary

Exception	Description
FoundIndex	Class to let us know when it's time to do a search from the parent because of indexing.
XPathException	This class implements an exception object that all XPath classes will throw in case of an error.
XPathProcessorException	Derived from XPathException in order that XPath processor exceptions may be specifically caught.
