Package net.sf.saxon.expr.parser

This package contains classes associated with parsing and general static analysis of XPath expressions.

Interface Summary

Interface	Description
CodeInjector	A code injector can be used to add code to the expression tree (for example, diagnostic tracing code) during the process of parsing and tree construction
ExpressionTool.ExpressionPredicate
ExpressionTool.ExpressionSelector	Callback for selecting expressions in the tree
TypeCheckerEnvironment	An abstraction of ExpressionVisitor that provides the minimal set of services needed by the TypeChecker; used to allow run-time type-checking of higher order function arguments without retaining the whole static context

Class Summary

Class	Description
ContextItemStaticInfo	A data structure that represents the required type of the context item, together with information about whether it is known to be present or absent or whether it is not known statically whether it is present or absent.
ExpressionLocation	Class to hold details of the location of an expression, of an error in a source file, etc.
ExpressionTool	This class, ExpressionTool, contains a number of useful static methods for manipulating expressions.
ExpressionVisitor	The ExpressionVisitor supports the various phases of processing of an expression tree which require a recursive walk of the tree structure visiting each node in turn.
Optimizer	This class performs optimizations that vary between different versions of the Saxon product.
PathMap	A PathMap is a description of all the paths followed by an expression.
PathMap.PathMapArc	An arc joining two nodes in the path map.
PathMap.PathMapNode	A node in the path map.
PathMap.PathMapNodeSet	A (mutable) set of nodes in the path map
PathMap.PathMapRoot	A root node in the path map.
PromotionOffer	PromotionOffer is an object used transiently during compilation of an expression.
RoleLocator	A RoleLocator identifies the role in which an expression is used, for example as the third argument of the concat() function.
Token	This class holds static constants and methods defining the lexical tokens used in XPath and XQuery, and associated keywords.
Tokenizer	Tokenizer for expressions and inputs.
TypeChecker	This class provides Saxon's type checking capability.
XPathParser	Parser for XPath expressions and XSLT patterns.
