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
ExpressionAction	General action class which can be used to process all nodes on an expression tree
ExpressionTool.ExpressionPredicate
ExpressionTool.ExpressionSelector	Callback for selecting expressions in the tree
ICompilerService	Marker interface representing a bytecode generation service
Location	Saxon interface to represent a location, typically the location of an expression within a query or stylesheet.
XPathParser.Accelerator

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.
Evaluator	An Evaluator evaluates an expression to return a sequence
ExplicitLocation	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.
LoopLifter	Class to handle loop-lifting optimization, that is, extraction of subexpressions appearing within a loop when there is no dependency on the controlling variable of the loop.
Optimizer	This class performs optimizations that vary between different versions of the Saxon product.
OptimizerOptions	Defines switches that can be used to control which optimizations take place.
ParserExtension	Dummy Parser extension for syntax in XPath that is accepted only in Saxon-PE and -EE.
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.
RebindingMap	A map from old bindings to new bindings, maintained during a copy() operation applied to an expression tree.
RetainedStaticContext	This class contains the part of the static context of expressions that (a) can change from one expression to another within a query or stylesheet, and (b) are potentially needed at run-time.
RoleDiagnostic	A RoleDiagnostic (formerly 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.
XPathParser.NestedLocation	A nested location: for use with XPath expressions and queries nested within some larger document.
