Class FrameIndexSelection

object --+
         |
        FrameIndexSelection

A class that defines a static set of indices to be selected from all frames.

Instance Methods

__init__(self, indices)
Initialize.

isDynamic(self)
Returns: A bool indicating whether this selection changes from frame to frame.

getOffsets(self, frame)
Returns: A selection as a sequence of integers, using zero based indexing so it can be used with a numpy array.

getArraySelection(self, frame)
Returns: A selection as a sequence of integers, using zero based indexing so it can be used with a numpy array.

getAtomIndices(self, frame)
Returns: A selection as a sequence of integers, using one based indexing so it can be used with a Structure.
