DefaultTransferEvent

public DefaultTransferEvent()

Method Detail

getType

public TransferEvent.EventType getType()

Description copied from interface: TransferEvent

Gets the type of the event.

Specified by:

getType in interface TransferEvent

Returns:

The type of the event, never null.

setType

public DefaultTransferEvent setType(TransferEvent.EventType type)

Sets the type of the event.

Parameters:

type - The type of the event, must not be null.

Returns:

This event for chaining, never null.

getRequestType

public TransferEvent.RequestType getRequestType()

Description copied from interface: TransferEvent

Gets the type of the request/transfer.

Specified by:

getRequestType in interface TransferEvent

Returns:

The type of the request/transfer, never null.

setRequestType

public DefaultTransferEvent setRequestType(TransferEvent.RequestType requestType)

Sets the type of the request/transfer.

Parameters:

requestType - The request/transfer type, must not be null.

Returns:

This event for chaining, never null.

getResource

public TransferResource getResource()

Description copied from interface: TransferEvent

Gets the resource that is being transferred.

Specified by:

getResource in interface TransferEvent

Returns:

The resource being transferred, never null.

setResource

public DefaultTransferEvent setResource(TransferResource resource)

Sets the resource being transferred.

Parameters:

resource - The resource being transferred, must not be null.

Returns:

This event for chaining, never null.

getTransferredBytes

public long getTransferredBytes()

Description copied from interface: TransferEvent

Gets the total number of bytes that have been transferred since the download/upload was started.

Specified by:

getTransferredBytes in interface TransferEvent

Returns:

The total number of bytes that have been transferred since the transfer started, never negative.

See Also:

TransferEvent.getDataLength()

setTransferredBytes

public DefaultTransferEvent setTransferredBytes(long transferredBytes)

Sets the total number of bytes that have been transferred so far during the download/upload.

Parameters:

transferredBytes - The total number of bytes that have been transferred so far during the download/upload, must not be negative.

Returns:

This event for chaining, never null.

getDataLength

public int getDataLength()

Description copied from interface: TransferEvent

Gets the number of bytes that have been transferred since the last event.

Specified by:

getDataLength in interface TransferEvent

Returns:

The number of bytes that have been transferred since the last event, possibly zero but never negative.

See Also:

TransferEvent.getTransferredBytes()

getDataBuffer

public ByteBuffer getDataBuffer()

Description copied from interface: TransferEvent

Gets the byte buffer holding the transferred bytes since the last event. A listener must assume this buffer to be owned by the event source and must not change any byte in this buffer. Also, the buffer is only valid for the duration of the event callback, i.e. the next event might reuse the same buffer (with updated contents). Therefore, if the actual event processing is deferred, the byte buffer would have to be cloned to create an immutable snapshot of its contents.

Specified by:

getDataBuffer in interface TransferEvent

Returns:

The (read-only) byte buffer or null if not applicable to the event, i.e. if the event type is not TransferEvent.EventType.PROGRESSED.

setDataBuffer

public DefaultTransferEvent setDataBuffer(byte[] buffer,
                                          int offset,
                                          int length)

Wraps the given byte[]-array into a ByteBuffer as the content for this event.

Parameters:

buffer - The array to use, must not be null.

offset - the starting point of valid bytes in the array.

length - the number of valid bytes.

Returns:

This event for chaining, never null.

setDataBuffer

public DefaultTransferEvent setDataBuffer(ByteBuffer dataBuffer)

Sets the byte buffer holding the transferred bytes since the last event.

Parameters:

dataBuffer - The byte buffer holding the transferred bytes since the last event, may be null.

Returns:

This event for chaining, never null.

getException

public Exception getException()

Description copied from interface: TransferEvent

Gets the error that occurred during the transfer.

Specified by:

getException in interface TransferEvent

Returns:

The error that occurred or null if none.

setException

public DefaultTransferEvent setException(Exception exception)

Sets the error that occurred during the transfer.

Parameters:

exception - The error that occurred during the transfer, may be null if none.

Returns:

This event for chaining, never null.

toString

public String toString()

Overrides:

toString in class Object
