translateFromback to summary
public void translateFrom(ClassGenerator classGen, MethodGenerator methodGen, Class<?> clazz)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type.translateFrom.

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

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

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type.translateTo.

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.

com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type#translateTo
translateToback to summary
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().

com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type#translateTo
translateToback to summary
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.

com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type#translateTo
translateToback to summary
public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, RealType type)

translateToback to summary
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.

See Also
com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type#translateTo
translateToback to summary
public void translateTo(ClassGenerator classGen, MethodGenerator methodGen, Class<?> clazz)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type.translateTo.

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 com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type.translateToDesynthesized.

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.
