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).

Description

Class Summary

BreakInstr	A compiled xsl:break instruction.
ContextCall	The class ContextCall is an expression which, when evaluated, calls a given FunctionItem supplying the context item as the only argument.
CopyRuleSet	The built-in rule set introduced in XSLT 3.0, which is effectively an identity template.
DiscardRuleSet	The rule set introduced in XSLT 3.0, which (for any kind of node) simply ignores the node and its descendants.
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.
EvaluateInstr	An EvaluateInstr is the compiled form of an xsl:evaluate instruction
FailRuleSet	The built-in rule set introduced in XSLT 3.0, which raises an error when there is no user-supplied template rule that matches a node.
Fork	This class implements an xsl:fork expression.
IndexedFilterExpression	An IndexedFilterExpression contains a base expression and a filter predicate.
IndexedLookupExpression	An IndexedLookupExpression contains a base expression and a lookup expression.
IndexedSequence	IndexedSequence is a simple package of information returned by saxon:index(), and used by saxon:find().
IndexedValue	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.
IterateInstr	An IterateInstr is the compiled form of a saxon:iterate instruction
JavaExtensionFunctionCall	This class acts as a container for an extension function defined to call a method in a user-defined class.
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.
NextIteration	Implements a xsl:next-iteration instruction within the body of xsl:iterate
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.
Query30Parser	Parser extension for new syntax in XQuery 3.0 (was 1.1).
QueryLibraryImpl	Concrete implementation of a separately-compiled XQuery library
RuleSetWithWarnings	A set of built-in template rules that performs the same action as an underlying set of rules, but with the addition of a warning message saying that no user-defined template rules was found.
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.
XPath30Parser	Parser extension for new syntax in XPath 3.0.
XPath30Parser.InlineFunctionDetails

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.
