Method Detail

getType

public int getType()

toString

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

identicalTo

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

hashCode

public int hashCode()
Overrides:
hashCode in class java.lang.Object

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 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.

                        MethodGenerator methodGen,
                        ObjectType type)
Subsume Node into ObjectType.

translateToDesynthesized

public FlowList translateToDesynthesized(ClassGenerator classGen,

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