Method Details

getIdentifier

public OperationIdentifier<T> getIdentifier()

Description copied from interface: OperationHandle

Returns a unique identifier for this operation

Specified by:

getIdentifier in interface OperationHandle<T extends Annotation>

Returns:

A non-null unique identifier for this operation

getState

public OperationState getState()

Description copied from interface: OperationHandle

Gets the current state of this operation

Specified by:

getState in interface OperationHandle<T extends Annotation>

Returns:

The current state of this operation

shutdownByFiat

void shutdownByFiat()

operationLock must be held

checkState

private void checkState()

getActiveThreads

public Set<Long> getActiveThreads()

Description copied from interface: OperationHandle

Gets a set of threads upon which this Operation is active

Specified by:

getActiveThreads in interface OperationHandle<T extends Annotation>

Returns:

The set of threads upon which this Operation is active

suspend

public void suspend(long threadId)

Description copied from interface: OperationHandle

Suspends this operation on the given thread id. If this Operation is not associated with the given threadId this method does nothing

Specified by:

suspend in interface OperationHandle<T extends Annotation>

Parameters:

threadId - The thread on which to suspend this operation

suspend

public void suspend()

Description copied from interface: OperationHandle

Suspends this operation on the current thread. If this Operation is not associated with the current threadId this method does nothing

Specified by:

suspend in interface OperationHandle<T extends Annotation>

resume

public void resume(long threadId)
            throws IllegalStateException

Description copied from interface: OperationHandle

Resumes this operation on the given thread id. If this Operation is already associated with the given threadId this method does nothing

Specified by:

resume in interface OperationHandle<T extends Annotation>

Parameters:

threadId - The thread on which to resume this operation

Throws:

IllegalStateException - if the Operation is closed or if the given thread is associated with a different Operation of the same type

resume

public void resume()
            throws IllegalStateException

Description copied from interface: OperationHandle

Resumes this operation on the current thread. If this Operation is already associated with the current thread this method does nothing

Specified by:

resume in interface OperationHandle<T extends Annotation>

Throws:

IllegalStateException - if the Operation is closed or if the current thread is associated with a different Operation of the same type

closeOperation

public void closeOperation()

Description copied from interface: OperationHandle

suspends this Operation on all threads where it is associated and closes the operation. All resume calls on this handle after this is called will throw IllegalStateException. If this handle is already closed this method does nothing

Specified by:

closeOperation in interface OperationHandle<T extends Annotation>

getOperationData

public Object getOperationData()

Description copied from interface: OperationHandle

Gets arbitrary Operation data to be associated with this Operation

Specified by:

getOperationData in interface OperationHandle<T extends Annotation>

Returns:

Arbitrary (possibly null) data that is associated with this Operation

setOperationData

public void setOperationData(Object data)

Description copied from interface: OperationHandle

Sets arbitrary Operation data to be associated with this Operation

Specified by:

setOperationData in interface OperationHandle<T extends Annotation>

Parameters:

data - (possibly null) data that is associated with this Operation

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
