Method Detail

setNodes

void setNodes(List<N> nodes)
              throws ConfigurationException

Configuration runtime injects node instances into flow using this method.

Parameters:

nodes - Nodes.

Throws:

ConfigurationException

setTransitions

void setTransitions(List<T> transitions)
                    throws ConfigurationException

Configuration runtime injects transition instances into flow using this method.

Parameters:

transitions -

Throws:

ConfigurationException

setFacadeInterface

void setFacadeInterface(Class<?> facadeInterface)

Configuration runtime injects facade interface class into flow using this method.

Parameters:

facadeInterface -

getFacade

Object getFacade()

Returns:

Proxy facade for this flow or null if facade interface was not specified in the definition.

connect

void connect(int nodeIdx,
             String pinName,
             int transitionIdx,
             boolean isInbound,
             K connectKey)
             throws ConfigurationException

Connects contents of the flow (internal nodes).

Parameters:

nodeIdx - Node index. The flow itself has index -1.

pinName - Pin name.

transitionIdx - Transition index.

isInbound - True if transition is directed to the pin, false otherwise.

connectKey - Connect key.

Throws:

ConfigurationException

setBackEnd

void setBackEnd(Object object)

Sets back-end object (optional operation). If back-end object is set, flow connects its pins to the back-end object methods with matching names. This is a convenience method for embedding flows into Java programs.

Parameters:

object -
