Package com.saxonica.expr

This package contains classes used to support expressions and instructions that are new in XPath 3.0, XQuery 3.0, or XSLT 3.0, and that don't fit conveniently into a more specialized category (such as streaming).

Class Summary

Class	Description
Annotation30	This class represents an annotation that appears in a function or variable declaration
EquivalenceComparer	A comparer that compares atomic values for equality, with the properties: - non-comparable types compare false - NaN compares equal to NaN
EquivalenceComparison	Class to handle equivalence comparisons of singletons.
ExtendedXQueryParser	Parser extension for new syntax in XQuery Update and/or XQuery 3.0.
IndexedFilterExpression	An IndexedFilterExpression contains a base expression and a filter predicate.
IndexedLookupExpression	An IndexedLookupExpression contains a base expression and a lookup expression.
IndexedValue<T extends Item>	A representation of a (sequence) value that allows the construction of one or more indexes to provide rapid access to the items in the sequence.
JavaExtensionFunctionCall	This class acts as a container for an extension function defined to call a method in a user-defined class.
JavaExtensionFunctionCall.ConfigurationCheckingFunction	This class checks that NodeInfo objects returned by an extension function were created under the right Configuration
MemoFunction	A user-defined function that is declared as a memo function, meaning that it remembers results of previous calls.
MultiIndex	A MultiIndex provides fast access to the items in a sequence.
OuterForExpression	Expression class that implements the "outer for" clause of XQuery 1.1
PathFinder	This class enables a client to find all nodes in a document that match a particular pattern.
QueryLibraryImpl	Concrete implementation of a separately-compiled XQuery library
StaticQueryContextPE	A version of StaticQueryContext for Saxon-PE, that extends the capability by allowing compilation of XQuery 1.1 syntax
SwitchExpression	An optimized Choose expression in which all the branches are tests of the same expression for equality with some value.
TryCatch	This class implements a try/catch expression.
TryCatch.CatchClause
XPath30Parser	Parser extension for new syntax in XPath 3.0.
XPath30Parser.InlineFunctionDetails
XPath30Parser.TemporaryXSLTVariableBinding

Package com.saxonica.expr Description

This package contains classes used to support expressions and instructions that are new in XPath 3.0, XQuery 3.0, or XSLT 3.0, and that don't fit conveniently into a more specialized category (such as streaming). Most of these classes represent internally-generated expressions or functions on the expression tree; the package also includes the XPath 3.0 and XQuery 3.0 parser extensions, and the Saxon-EE optimizer.

None of these classes will be used by typical user applications.

The subpackage com.saxonica.expr.ee contains classes that belong to the same general category, but are specific to Saxon-EE as distinct from Saxon-PE.
