Method Detail

getAction

ExecutionPlan.Action getAction(String sId)

Obtains the proposed ExecutionPlan.Action for the specified Executor.

Parameters:

sId - the Executor id

Returns:

an ExecutionPlan.Action or null if no ExecutionPlan.Action has been defined

setAction

boolean setAction(String sId,
                  ExecutionPlan.Action action)

Sets the proposed ExecutionPlan.Action for the specified Executor.

Parameters:

sId - the Executor id

action - the ExecutionPlan.Action to set to

Returns:

a boolean to indicate if the ExecutionPlan was changed as a result of setting an action

size

int size()

Obtains the number of ExecutionPlan.Actions for the ExecutionPlan.

Returns:

the number of ExecutionPlan.Actions

getIds

Iterator<String> getIds()

Obtains the unique identities of Executors with ExecutionPlan.Actions.

Returns:

the Executor identities.

count

int count(Predicate<? super ExecutionPlan.Action> predicate)

Determines the number of a Executors whose ExecutionPlan.Actions satisfy the specified Predicate in the ExecutionPlan.

Parameters:

predicate - the Predicate to evaluate the ExecutionPlan.Action

Returns:

the number of Executors that satisfy the specified Predicate

isSatisfied

boolean isSatisfied()

Determines if the ExecutionPlan will satisfy the ExecutionStrategy conditions, including assigning the required number of Executors to a Task for execution.

Returns:

true when the ExecutionPlan satisfies the ExecutionStrategy that defined it false otherwise

getPendingRecoveryCount

int getPendingRecoveryCount()

Determines the current number of effective assignments of a Task to Executors that failed (for some reason), which could be re-assigned as a ExecutionPlan.Action.RECOVER action.

Returns:

the pending recovery count

optimize

boolean optimize()

Optimizes the ExecutionPlan, returning if there where any changes caused by the optimization.

Returns:

true if the ExecutionPlan was changed during optimization, false otherwise
