Method Detail

getType

public int getType()

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

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

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

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 node into an object of internal type type. The translation to int is undefined since nodes 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 node on the stack and pushes its string value.

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 node into a synthesized boolean. If the expression is "@attr", then "true" is pushed iff "attr" is an attribute of the current node. If the expression is ".", the result is always "true".

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 on the stack and pushes a real. First the node 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)

                        MethodGenerator methodGen,
                        NodeSetType type)

Expects a node on the stack and pushes a singleton node-set. Singleton iterators are already started after construction.

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)

Subsume Node 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 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:

                        ReferenceType type)

Expects a node on the stack and pushes a boxed node. Boxed nodes are represented by an instance of org.apache.xalan.xsltc.dom.Node.
