Interface DataFlowBinding

public interface DataFlowBinding

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 relationships.

Method Summary

Modifier and Type	Method and Description
void	activate() Activates a binding, adding the sub-graph defined by this binding to the main DataFlowGraph associated with this binding.
void	deactivate() 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.
boolean	isActive()
void	setListener(BindingListener bindingListener) Sets the BindingListener.

Method Detail

activate

void activate()

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.

deactivate

void deactivate()

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 developer.

isActive

boolean isActive()

Returns:

whether this binding has been activated and not yet deactivated.

setListener

void setListener(BindingListener bindingListener)

Sets the BindingListener.
