Constructor Detail

MultiOperation

public MultiOperation(IOperator operator)

Creates a new multi operation without any operations. This multi operation starts operation using the specified operator.

Parameters:

operator - The operator used to execute the operations.

Method Detail

addOperation

public void addOperation(IOperation operation)

Adds the specified operation to the set of operations that should be executed.

Parameters:

operation - The operation to execute.

removeOperation

public boolean removeOperation(IOperation operation)

Removes the specified operation from the set of operations that should be executed.

Parameters:

operation - The operation to execute.

Returns:

True if the operation has been removed, false otherwise.

getOperations

public IOperation[] getOperations()

Returns the operations that are contained in the multi operation.

Returns:

The operations of the multi operation.

performAsynchronous

public void performAsynchronous()

Performs the operations that have not been executed already an returns immediately.

performSynchronous

public void performSynchronous()

Performs the operations that have not been executed already and synchronizes on their end. Calling this method is more efficient than calling performAsynchronous and synchronizing on the end since this method will reuse the calling thread to perform one operation.

synchronize

public void synchronize()

Synchronizes on all operations that are currently executing and waits until they are finished.
