Method Detail

isAssignableFrom

public final boolean isAssignableFrom(Signature2 that)

isAssignableFrom

public final boolean isAssignableFrom(Signature that)

Description copied from interface: Signature

If this.isAssignableFrom(that), then a method defined for this can be used on an arglist whose signature is that.

Specified by:

isAssignableFrom in interface Signature

isAssignableFrom

public final boolean isAssignableFrom(java.lang.Class k0,
                                      java.lang.Class k1)

Description copied from interface: Signature

If this.isAssignableFrom(k0,k1), then a method defined for this can be used on a length 2 arglist whose classes are k0, k1.

This eliminates the need to create signature instances in a common special case.

Specified by:

isAssignableFrom in interface Signature

isAssignableFrom

public final boolean isAssignableFrom(java.lang.Class k0,
                                      java.lang.Class k1,
                                      java.lang.Class k2)

Description copied from interface: Signature

If this.isAssignableFrom(k0,k1,k2), then a method defined for this can be used on a length 3 arglist whose classes are k0, k1, k3.

This eliminates the need to create signature instances in a common special case.

Specified by:

isAssignableFrom in interface Signature

isAssignableFrom

public final boolean isAssignableFrom(java.lang.Class... ks)

Description copied from interface: Signature

If this.isAssignableFrom(ks), then a method defined for this can be used on a length 3 arglist whose classes are the elements of ks.

This eliminates the need to create signature instances in a common special case.

Specified by:

isAssignableFrom in interface Signature
