Method Detail

toString

public java.lang.String toString()
Overrides:
toString in class Type

identicalTo

public boolean identicalTo(Type other)
Overrides:
identicalTo in class Type

toSignature

public java.lang.String toSignature()
Overrides:
toSignature in class Type

isSimple

public boolean isSimple()
Overrides:
isSimple in class Type

toJCType

public org.apache.bcel.generic.Type toJCType()
Overrides:
toJCType in class Type

translateTo

public void translateTo(ClassGenerator classGen,
                        MethodGenerator methodGen,
                        Type type)
Translates a string into an object of internal type type. The translation to int is undefined since strings are always converted to reals in arithmetic expressions.
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,
                        BooleanType type)
Translates a string into a synthesized boolean.
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,
                        RealType type)
Translates a string into a real by calling stringToReal() from the basis library.
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)

translateToDesynthesized

public FlowList translateToDesynthesized(ClassGenerator classGen,
                                         MethodGenerator methodGen,
                                         BooleanType type)
Translates a string 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.
Overrides:
translateToDesynthesized in class Type
See Also:
Type.translateToDesynthesized(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 string on the stack and pushes a boxed string. Strings are already boxed so the translation is just a NOP.
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,
                        java.lang.Class clazz)
Translates a internal string into an external (Java) string.
Overrides:
translateTo in class Type
See Also:
Type.translateFrom(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, java.lang.Class)

translateFrom

public void translateFrom(ClassGenerator classGen,
                          MethodGenerator methodGen,
                          java.lang.Class clazz)
Translates an external (primitive) Java type into a string.
Overrides:
translateFrom in class Type
See Also:
Type.translateFrom(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, java.lang.Class)

translateBox

public void translateBox(ClassGenerator classGen,
                         MethodGenerator methodGen)
Translates an object of this type to its boxed representation.
Overrides:
translateBox in class Type

translateUnBox

public void translateUnBox(ClassGenerator classGen,
                           MethodGenerator methodGen)
Translates an object of this type to its unboxed representation.
Overrides:
translateUnBox in class Type

getClassName

public java.lang.String getClassName()
Returns the class name of an internal type's external representation.
Overrides:
