Constructor Detail

FieldReference

public FieldReference(Reference base,
                      java.lang.String name)

Create a new field reference. The specified base reference must have a struct or union type with a member of the specified name. The type of the newly created field reference is the named member's type, unless that type is an array, in which case the type is the array's element type.

Parameters:

base - The base reference.

name - The member name.

Throws:

java.lang.ClassCastException - Signals that the base reference is does not have a struct or union.

java.lang.IllegalArgumentException - Signals that the base reference does not have a struct/union with the named member.
