Defines the relationship of a set of input values to a set of output values where the values from
the input nodes 'flow into' the output nodes. For example, input values could be a touch X/Y or a
layout value, and output values could be the X/Y position of a View or its opacity. Input and
output values can be connected to each other via intermediate operators like springs or timing.
A DataFlowBinding may represent a single one of these relationships, or a set of these
Activates a binding, adding the sub-graph defined by this binding to the main
DataFlowGraph associated with this binding. This is expected to be called from
framework code and should not be called by the end developer.
Deactivates this binding which, as you might guess, is the reverse of activating it: the
sub-graph associated with this binding is removed from the main DataFlowGraph. As with
activate(), this is expected to only be called by framework code and not the end
whether this binding has been activated and not yet deactivated.
