Enclosing class:

Seq

public static final class Seq.SeqType

extends java.lang.Object

A type-safe enum for identifying the type of a Seq object. Usable to verify downcasts. Implements a very simple numeric pyramid and allows one to check the downcastability of interfaces simply.

Method Detail

hasInterface

public boolean hasInterface(Seq.SeqType type)

Returns true if this SeqType instance guarantees the named interface. In other words, can a Seq having this type be cast to the interface associated with the type value.

Parameters:

type - the TypeSeq enum naming the requested interface

Returns:

true if a Seq with this type can be cast to the interface named
