The codegen package contains the Java code generator for XQuery.
The only class designed to be used directly by user applications is QueryCompiler,
which can be used to drive the compilation of a query from a Java application. Normally, however,
query compilation will be done from the command line using the com.saxonica.CompileQuery
entry point.
The other classes in this package fall into two categories:
CastExpressionCompiler is used to generate code for a cast expression;CompilerService, which handles much of the
logic for tracking the generation of different parts of the Java output.
