Uses of Class
org.apache.xpath.compiler.Compiler

Packages that use Compiler

Package	Description
org.apache.xpath.axes	Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
org.apache.xpath.compiler	Implements an XPath parser which produces an OpMap, and a so-called Compiler which produces an expression tree for fast evaluation.
org.apache.xpath.functions	Implements XPath functions -- each function is derived from Function, FunctionOneArg, Function2Args, etc, with number-of-arguments checking being applied mainly at compile time -- this package only implements XPath functions, XSLT functions are found in the "templates" package.

Uses of Compiler in org.apache.xpath.compiler

Methods in org.apache.xpath.compiler with parameters of type Compiler

Modifier and Type	Method and Description
void	XPathParser.initMatchPattern(Compiler compiler, String expression, PrefixResolver namespaceContext) Given an string, init an XPath object for pattern matches, in order that a parse doesn't have to be done each time the expression is evaluated.
void	XPathParser.initXPath(Compiler compiler, String expression, PrefixResolver namespaceContext) Given an string, init an XPath object for selections, in order that a parse doesn't have to be done each time the expression is evaluated.
