Constructor Detail

_Actor

protected _Actor(java.lang.String name,
                 int repetitionCount,
                 int sharedBuffersNeeded,
                 int exclusiveBuffersNeeded,
                 int sharedExecutionTimeNeeded,
                 int exclusiveExecutionTimeNeeded)

Construct an instance of Actor, providing its name, repetition vector count and profile information.

Parameters:

name - name for the actor

repetitionCount - repetition vector entry of the actor

sharedBuffersNeeded - number of frame buffers needed for shared firing

exclusiveBuffersNeeded - number of frame buffers needed for exclusive firing

sharedExecutionTimeNeeded - execution time needed for share firing

exclusiveExecutionTimeNeeded - execution time needed for exclusive firing

Method Detail

assignStateIndex

int assignStateIndex(int index)

Assign stateIndex to actor and its ports and returns the index for the next component.

Parameters:

index - index to assign to the actor

Returns:

index to assign to next actor

isEnabled

boolean isEnabled(OptimalScheduleFinder._State state)

Test whether the actor is enabled for a shared firing in given state state.

Parameters:

state - state

Returns:

true if enabled

isExclusiveEnabled

boolean isExclusiveEnabled(OptimalScheduleFinder._State state)

Test whether the actor is enabled for an exclusive firing in given state state.

Parameters:

state - state

Returns:

true if enabled

fire

void fire(OptimalScheduleFinder._State state)

adapt state 'state' according to a shared firing. Assumes it is enabled.

Parameters:

state - state
