List of all members.


Detailed Description

The Ipo object
==============
This object gives access to Ipo data from all objects in Blender.
@Note: Blender Materials, Lamps and Worlds have I{texture channels} which
allow the user to assign textures to them.  The Blender Ipo Window allows
the user to access the IpoCurves for these channels by specifying a number
between 0 and 9 (the number appears next to the Ipo type in the window
header).  Prior to Version 2.42, the BPy API did not allow users to access
these texture channels in a predictable manner.  A new attribute named
L{channel} was added to the API in Version 2.42 to correct this problem.

The current channel setting has an effect on the operators B{[]}, B{len()} 
and others.  For example, suppose a Material has three IpoCurves 
(R, G, and B), and two texture channels (numbered 0 and 1), and furthermore
channel 0 has one Ipocurve (Col).  The IpoCurve Col can only be
"seen" through the API when B{ipo.channel} is 0.  Setting B{ipo.channel} to
1 will cause this curve to be ignored by B{len(ipo)}::

      from Blender import Ipo

      ipo = Ipo.Get('MatIpo')
      for channel in xrange(2):
                  ipo.channel = channel
                  print 'channel is',channel
                  print ' len is',len(ipo)
                  names = dict([(x[1],x[0]) for x in ipo.curveConsts.items()])
                  for curve in [Ipo.MA_R,Ipo.MA_COL]:
                              print ' ',names[curve],'is',curve in ipo

will output::
      channel is 0
      len is 4
            MA_R is True
            MA_COL is True
      channel is 1
      len is 3
            MA_R is True
            MA_COL is False

@ivar curves: Ipo curves currently defined for the Ipo.
@type curves: list of Ipocurves.
@ivar curveConsts: The valid Ipo curves for this Ipo.  These can be used
by the [] mapping operator.  The value 
depends on the Ipo curve type.  If the Ipo is any type other than a Key or
Shape Ipo, this attribute returns a set of constants that can be
used to specify a particular curve.  For Key or Shape Ipos, the attribute
returns a list of all defined keys by name.  
@type curveConsts: constant or list of strings. Read-only.
@ivar channel: the current texture channel for Blender object which support
textures (materials, lamps and worlds).  Returns None if the Ipo does
not support texture channels. Value must be in the range [0,9].
@type channel: int or None
