All Implemented Interfaces:

HasSetter, Named, Externalizable, Serializable

public class GetNamedInstancePart
extends ProcedureN
implements Externalizable, HasSetter

The value of the Kawa Scheme expression '*:PART-NAME'. This function invokes a method or accesses a field, if the PART-NAME starts with a '.'. This syntax is semi-deprecated, since instead of (*:method-name instance args ...) you can now write (instance:method-name args ...), and instead of (*:.field-name instance) you can write instance:field-name (without the parentheses).

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.
