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
ExpressionAction	General action class which can be used to process all nodes on an expression tree
ICompilerService	Marker interface representing a bytecode generation service
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
Evaluator.EagerSequence	An evaluator for arguments that in general return a sequence, where the sequence is evaluated eagerly.
Evaluator.EmptySequenceEvaluator	An evaluator that always returns the empty sequence
Evaluator.LazySequence	An evaluator for arguments that in general return a sequence, where the sequence is evaluated lazily on first use.
Evaluator.LazyTail	An evaluator for arguments that in general return a sequence, where the sequence is evaluated lazily on first use.
Evaluator.Literal	An evaluator for arguments supplied as a literal
Evaluator.MakeIndexedVariable	An evaluator for an expression that makes use of an indexed variable
Evaluator.MemoClosureEvaluator	An evaluator for arguments that in general return a sequence, where the sequence is evaluated lazily on first use, and where the value might be needed more than once.
Evaluator.OptionalItem	A (default) evaluator for arguments supplied as an expression that will return either a singleton item, or an empty sequence
Evaluator.Process	A push-mode evaluator for an expression
Evaluator.SharedAppend	An evaluator for "shared append" expressions: used when the argument to a function is a block potentially containing a recursive call.
Evaluator.SingleItem	A (default) evaluator for arguments supplied as an expression that will always return a singleton item
Evaluator.SingletonClosure	An evaluator for arguments that in general return a sequence, where the sequence is evaluated lazily on first use, and where the value might be needed more than once.
Evaluator.StreamingArgument	An evaluator for the first (streamed) argument of a streamable function call.
Evaluator.SuppliedParameter	An evaluator for a reference to an external parameter value
Evaluator.Variable	An evaluator for arguments supplied as a variable reference
Evaluators	Constants for different mechanisms of expression evaluation
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.
Loc	Class to hold details of the location of an expression, of an error in a source file, etc.
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 particular product variants.
ParserExtension.TemporaryXSLTVariableBinding
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.InlineFunctionDetails
XPathParser.NestedLocation	A nested location: for use with XPath expressions and queries nested within some larger document.
