Detailed Description

Visual Representation of an Edge.
An Edge can have up to two Bands - one with positive altitude and one negative.
Visual Parameters
Rank - the Z drawing order (higher values closer to user)
Altitude - the distance above or below the Block ribbon

def diarc.diarc.topology.Band.bottomBand ( self )

Returns the band with the next lowest altitude, or None if either
there is no band below this one or the block ribbon is below it.
Bands for which isUsed() is false are skipped over.

def diarc.diarc.topology.Band.collectors ( self )

returns list of sink snaps that reach this band

Definition at line 515 of file topology.py.

returns a list of source snaps that reach this band

def diarc.diarc.topology.Band.isUsed ( self )

returns true if this band is needed to represent connections on
its edge, else false. This is determined by checking if any sources
reach this band.

Definition at line 532 of file topology.py.

def diarc.diarc.topology.Band.topBand ( self )

Returns the band with the next highest altitude, or None if either
there is no band above this one or the block ribbon is above it.
Bands for which isUsed() is false are skipped over.
