Method Detail

findPast

public PropFinder findPast(BeEdition stamp)

Description copied from class: PropFinder

During a southwards walk of a multi-Edition (aka multi-Stamp), normally we simplify the
finder by using PropFinder>>pass:. However, when we cross an internal Edition boundary
and are about to walk into the O-plane of that contained edition we call this method
(findPast:) to get the new PropFinder.

Overrides:

findPast in class PropFinder

isEmpty

public boolean isEmpty()

Overridden only here

Overrides:

isEmpty in class PropFinder

match

public boolean match(Prop prop)

tell whether a prop matches this filter

Overrides:

match in class PropFinder

pass

public PropFinder pass(CanopyCrum crum)

Description copied from class: PropFinder

return a simple enough finder for looking at the children

Overrides:

pass in class PropFinder

actualHashForEqual

public int actualHashForEqual()

Overrides:

actualHashForEqual in class PropFinder

isEqual

public boolean isEqual(Heaper other)

Description copied from class: Heaper

Return true if the two objects are equal.

Overrides:

isEqual in class Heaper

sendSelfTo

public void sendSelfTo(Xmtr xmtr)

Description copied from class: Heaper

do nothing

Overrides:

sendSelfTo in class Heaper
