Method Detail

toString

public java.lang.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 java.lang.String toSignature()

Description copied from class: Type

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

Specified by:

toSignature in class Type

isSimple

public boolean isSimple()

Description copied from class: Type

Returns true if this type is a simple type. Redefined in NumberType, BooleanType and StringType.

Overrides:

isSimple in class Type

toJCType

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

Specified by:

toJCType in class Type

translateTo

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

Translates a real into an object of internal type type. The translation to int is undefined since booleans 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,
                        StringType type)

Expects a boolean on the stack and pushes a string. If the value on the stack is zero, then the string 'false' is pushed. Otherwise, the string 'true' is pushed.

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)

Expects a boolean on the stack and pushes a real. The value "true" is converted to 1.0 and the value "false" to 0.0.

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,
                        ReferenceType type)

Expects a boolean on the stack and pushes a boxed boolean. Boxed booleans are represented by an instance of java.lang.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)

Translates an external (Java) boolean into internal boolean.

Overrides:

translateFrom in class Type

translateBox

public void translateBox(ClassGenerator classGen,
                         MethodGenerator methodGen)
