Method Detail

doesPass

public boolean doesPass(CanopyCrum parent)

return whether the propJoint passes the finder

findPast

public PropFinder findPast(BeEdition stamp)

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.

flags

public int flags()

isEmpty

public boolean isEmpty()

Overridden only in ClosedPropFinder

isFull

public boolean isFull()

Overridden only in OpenPropFinder

match

public boolean match(Prop prop)

tell whether a prop matches this filter

pass

public PropFinder pass(CanopyCrum parent)

return a simple enough finder for looking at the children

actualHashForEqual

public int actualHashForEqual()

Overrides:
