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

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 node-set into an object of internal type type. The translation to int is undefined since node-sets 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)

translateFrom

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

Translates an external Java Class into an internal type. Expects the Java object on the stack, pushes the internal type

Overrides:

translateFrom in class Type

translateTo

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

Translates a node-set into a synthesized boolean. The boolean value of a node-set is "true" if non-empty and "false" otherwise. Notice that the function getFirstNode() is called in translateToDesynthesized().

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 node-set into a string. The string value of a node-set is value of its first element.

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 node-set on the stack and pushes a real. First the node-set is converted to string, and from string to real.

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,
                        NodeType type)

Expects a node-set on the stack and pushes a node.

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,
                        ObjectType type)

Subsume node-set into ObjectType.

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 node-set 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 node-set on the stack and pushes a boxed node-set. Node sets are already boxed so the translation is just a NOP.

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

translateTo

                        MethodGenerator methodGen,
                        java.lang.Class clazz)

Translates a node-set into the Java type denoted by clazz. Expects a node-set on the stack and pushes an object of the appropriate type after coercion.

Overrides:

public void translateBox(ClassGenerator classGen,
                         MethodGenerator methodGen)

Translates an object of this type to its boxed representation.
