Method Detail

toString

public String toString()

Description copied from class: Type

Returns a string representation of this type.

Specified by:

toString in class Type

identicalTo

public boolean identicalTo(Type other)

Description copied from class: Type

Returns true if this and other are identical types.

Specified by:

identicalTo in class Type

toSignature

public String toSignature()

Description copied from class: Type

Returns the signature of an internal type's external representation.

Specified by:

toSignature in class Type

toJCType

public org.apache.bcel.generic.Type toJCType()

Specified by:

toJCType in class Type

POP

public org.apache.bcel.generic.Instruction POP()

Overrides:

POP in class Type

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        Type type)

Translates a void into an object of internal type type. This translation is needed when calling external functions that return void.

Overrides:

translateTo in class Type

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,
                        StringType type)

Translates a void into a string by pushing the empty string ''.

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)

translateFrom

public void translateFrom(ClassGenerator classGen,
                          MethodGenerator methodGen,
                          Class clazz)

Translates an external (primitive) Java type into a void. Only an external "void" can be converted to this class.

Overrides:

translateFrom in class Type
