Method Detail

getChangeTime

public long getChangeTime()

Description copied from interface: IResult

Get the time stamp of when this result last changed state. In other words: If IResult.isDone() is false, returns the time when the request was sent. If IResult.isDone() is true, returns the time when the response was received.

Specified by:

getChangeTime in interface IResult<T[]>

Returns:

a time stamp (in milliseconds since 1970-01-01)

send

public AbstractMemLeak.DelayedTruncatable<T> send()

Returns:

DelayedTruncatable<T>

sendIfSupported

public ITruncatable<T> sendIfSupported()

If this request is unsupported, returns a ITruncatable result with an empty array and a reason of "UNSUPPORTED". Otherwise returns as send().

Returns:

ITruncatable<T>

See Also:

send()

getEmptyResult

protected T[] getEmptyResult()

Returns:

the empty result array

isDone

public boolean isDone()

Description copied from interface: IResult

Returns true if this task completed. Completion may be due to normal termination, an exception, or cancellation -- in all of these cases, this method will return true.

Specified by:

isDone in interface IResult<T[]>

Returns:

true if this task completed.

isDone

public boolean isDone(java.lang.Object notificationToken)

Description copied from interface: IResult

Checks if the result is available. If so, simply returns true. Otherwise, notificationToken is added to the token set that will be given to notification listeners once the result is available. And false is returned.

Specified by:

isDone in interface IResult<T[]>

Returns:

true if this task completed.

get

public T[] get()

Description copied from interface: ITruncatable

The actual result array, possibly truncated. This method will never return null.

Specified by:

get in interface IResult<T[]>

Specified by:

get in interface ITruncatable<T>

Returns:

an array, possibly empty.

parseResponse

protected abstract T[] parseResponse(java.io.DataInputStream dis)
                              throws java.io.IOException,
                                     GarbageCollectedException,
                                     SpiException

Parameters:

dis -

Returns:

T

Throws:

java.io.IOException

GarbageCollectedException

SpiException

isTruncated

public boolean isTruncated()

Specified by:

isTruncated in interface ITruncatable<T>

Returns:

true iff this array was truncated

getTruncationReason

public ITruncatable.Reason getTruncationReason()

Description copied from interface: ITruncatable

If the result was truncated, returns a ITruncatable.Reason for the truncation. Otherwise, null is returned. Note that if ITruncatable.getException() returns non-null, this method will also return non-null, most probably ITruncatable.Reason.EXCEPTION.

Specified by:

getTruncationReason in interface ITruncatable<T>

Returns:

the reason for truncation, or null if the result wasn't truncated.

getException

public java.lang.Exception getException()

Description copied from interface: ITruncatable

If an exception was thrown, returns that Exception. Otherwise, null is returned.

Specified by:

getException in interface ITruncatable<T>

Returns:

the thrown exception, if any, null otherwise.
