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 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.
