| 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 (Java) boolean into internal boolean.

Boxed booleans are represented by an instance of
java.lang.Boolean.

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

If the value on the
stack is zero, then the string 'false' is pushed. Otherwise, the string
'true' is pushed.

The value "true" is
converted to 1.0 and the value "false" to 0.0.
