## Package com.saxonica.bytecode Description

This package and its subpackages contain code responsible for bytecode generation under Saxon-EE.

The parent package contains one "Compiler" class for each expression class needing to be compiled. The association between the expression class (representing the node on the expression tree) and the associated compiler class is established by the class `CompilerClassMapper`.
