                        MethodGenerator methodGen,
                        Type type)
Translates a result tree to object of internal type type. The translation to int is undefined since result trees are always converted to reals in arithmetic expressions.
Parameters:

methodGen - A BCEL method generator
type - An instance of the type to translate the result tree to
Overrides:
translateTo in class Type

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        BooleanType type)
Expects an result tree on the stack and pushes a boolean. Translates a result tree to a boolean by first converting it to string.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
type - An instance of BooleanType (any)

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        StringType type)
Expects an result tree on the stack and pushes a string.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
type - An instance of StringType (any)

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        RealType type)
Expects an result tree on the stack and pushes a real. Translates a result tree into a real by first converting it to string.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
type - An instance of RealType (any)

Type.translateTo(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, org.apache.xalan.xsltc.compiler.util.Type)

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        ReferenceType type)
Expects a result tree on the stack and pushes a boxed result tree. Result trees are already boxed so the translation is just a NOP.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
type - An instance of ReferenceType (any)
See Also:
Type.translateTo(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, org.apache.xalan.xsltc.compiler.util.Type)

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        NodeSetType type)
Expects a result tree on the stack and pushes a node-set (iterator). Note that the produced iterator is an iterator for the DOM that contains the result tree, and not the DOM that is currently in use. This conversion here will therefore not directly work with elements such as and without the DOM parameter/variable being updates as well.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
type - An instance of NodeSetType (any)

                                         MethodGenerator methodGen,
                                         BooleanType type)
Translates a result tree into a non-synthesized boolean. It does not push a 0 or a 1 but instead returns branchhandle list to be appended to the false list.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
type - An instance of BooleanType (any)
Overrides:
translateToDesynthesized in class Type
See Also:

                        MethodGenerator methodGen,
                        java.lang.Class clazz)
Translates a result tree to a Java type denoted by clazz. Expects a result tree on the stack and pushes an object of the appropriate type after coercion. Result trees are translated to W3C Node or W3C NodeList and the translation is done via node-set type.
Parameters:
classGen - A BCEL class generator
methodGen - A BCEL method generator
clazz - An reference to the Class to translate to
Overrides:
translateTo in class Type
