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. -

WalkerFactory. newDTMIterator(Compiler compiler, int opPos, boolean isTopLevel)
Create a new LocPathIterator iterator.Constructors in org.apache.xpath.axes with parameters of type Compiler Constructor Description UnionPathIterator(Compiler compiler, int opPos)
Create a UnionPathIterator object, including creation of location path iterators from the opcode list, and call back into the Compiler to create predicate expressions. -
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, java.lang.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, java.lang.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. -
Uses of Compiler in org.apache.xpath.functions
Methods in org.apache.xpath.functions with parameters of type Compiler Modifier and Type Method Description void
FuncLast. postCompileStep(Compiler compiler)
