| public void | translateBox(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen)Translates an object of this type to its boxed representation.
translateTo(classGen, methodGen, Type.Reference);

| public void | translateFrom(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen, java.lang.Class clazz)Translates an external (primitive) Java type into a string.

Strings are already boxed so the translation is just a NOP.
methodGen.getInstructionList().append(NOP);

The translation to int is undefined since strings are always converted
to reals in arithmetic expressions.

final InstructionList il = methodGen.getInstructionList();
FlowList falsel = translateToDesynthesized(classGen, methodGen, type);

basis library.

It does not push a
0 or a 1 but instead returns branchhandle list to be appended to the
false list.
final ConstantPoolGen cpg = classGen.getConstantPool();
final InstructionList il = methodGen.getInstructionList();
il.append(new INVOKEVIRTUAL(cpg.addMethodref(STRING_CLASS,

| public void | translateUnBox(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen)Translates an object of this type to its unboxed representation.
