Description

Class Summary
GeneralComparisonEE | This class provides an implementation of the GeneralComparison "=" operator, which deals efficiently with comparing two sequences.
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
OptimizerEE | This class performs a number of optimizations that are specific to the Saxon-EE product.
StaticQueryContextEE | A version of StaticQueryContext for Saxon-EE, that extends the capability by allowing compilation of library modules.

## Package com.saxonica.expr.ee Description

This package contains classes used to support 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.
