Package com.saxonica.ee.optim

This package contains classes used to support optimized expressions and instructions that are specific to Saxon-EE, and that don't fit conveniently into a more specialized category (such as streaming).

Class Summary

Class	Description
CombinedChoice	A class that encompasses a set of template choices
GeneralComparisonEE	This class provides an implementation of the GeneralComparison "=" operator, which deals efficiently with comparing two sequences.
IndexedFilterExpression	An IndexedFilterExpression contains a base expression and a filter predicate.
IndexedLookupExpression	An IndexedLookupExpression contains a base expression and a lookup expression.
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.
MultiIndex	A MultiIndex provides fast access to the items in a sequence.
MultithreadedContextMappingIterator	This class performs the same role as ContextMappingIterator, but using multiple threads.
MultithreadedForEach	This instruction represents an xsl:for-each instruction using more than one thread
MultithreadedItemMappingIterator<F extends Item,T extends Item>	Parallel-processing version of the ItemMappingIterator class, which executes a mapping function for each item in a sequence.
OptimizerEE	This class performs a number of optimizations that are specific to the Saxon-EE product.
RewriteContext	A context used for rewriting expressions, principally providing variable binding slots
RuleOptimized	An optimized Rule
StaticQueryContextEE	A version of StaticQueryContext for Saxon-EE, that extends the capability by allowing compilation of library modules.
SwitchExpression	An optimized Choose expression in which all the branches are tests of the same expression for equality with some value.
SwitchExpression.SwitchCaseInfo	Data structure used for holding details of a switch expression
XQueryExpressionEE	Saxon-EE version of XQueryExpression.

Package com.saxonica.ee.optim Description

This package contains classes used to support optimized expressions and instructions that are specific to Saxon-EE, and that don't fit conveniently into a more specialized category (such as streaming). They include the Saxon-EE optimiser; the code to implement multithreading in xsl:for-each in XSLT, and the code to perform optimized evaluation of general comparisons.

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