Constructor Detail

HTTPResponseProcessor

public HTTPResponseProcessor(boolean headRequest)

Creates a new HTTPResponseProcessor.

Method Detail

addHTTPResponseCallback

public void addHTTPResponseCallback(HTTPResponseProcessor.HTTPResponseCallback hrc)

Adds an HTTPResponseProcessor.HTTPResponseCallback to this processor that will be called back as a data stream is processed.

Parameters:

hrc - the callback to add

removeHTTPResponseCallback

public void removeHTTPResponseCallback(HTTPResponseProcessor.HTTPResponseCallback hrc)

Removes an HTTPResponseProcessor.HTTPResponseCallback from this processor the removed callback will no longer be called.

Parameters:

hrc - the callback to remove.

getAllCallbacks

public java.util.Collection<HTTPResponseProcessor.HTTPResponseCallback> getAllCallbacks()

Gets all listeners that are on this processor.

Returns:

a collection of HTTPResponseProcessor.HTTPResponseCallback objects currently listening for data.

processData

public void processData(byte[] ba)

byte[] to send through the processor.

Parameters:

ba - to send through the processor.

processData

public void processData(java.nio.ByteBuffer bb)

ByteBuffer to send through the processor.

Parameters:

bb - ByteBuffer to send through the processor.

processData

public void processData(org.threadly.litesockets.buffers.MergedByteBuffers bb)

MergedByteBuffers to send through the processor.

Parameters:

bb - MergedByteBuffers to send through the processor.

connectionClosed

public void connectionClosed()

Called when an http response connection is closes. Some types of responses are only completed when the connection is closed (http1.0). This will finish all the callback and then reset the processor to be able to be reused if wanted.

clearBuffer

public void clearBuffer()

Resets the processor and any pending buffers left in it.

reset

public void reset()

Forces a reset on the HTTPProcessor. This will call finish on any set callbacks if a request has started. NOTE: any currently unprocessed buffer will remain! see clearBuffer()

reset

public void reset(java.lang.Throwable t)

Forces a reset on the HTTPProcessor with an error, call callbacks will be called with hasError if a request has started.

Parameters:

t - exception to pass to the callbacks. NOTE: any currently unprocessed buffer will remain! see clearBuffer()

isResponseComplete

public boolean isResponseComplete()

Lets you know if we have gotten enough data to see a full response yet.

Returns:

true if the response is completed false if not.

getBufferSize

public int getBufferSize()

returns the total amount of unprocessable data pending.

Returns:

the size of the pending unprocessed buffers.

getCurrentBodySize

public int getCurrentBodySize()

Gets the current body size for the httpResponse currently in process.

Returns:

the current body size in bytes. Will be -1 if streaming or not currently processing a response.

isProcessing

public boolean isProcessing()

Lets you know if a response is currently being processed or not.

Returns:

true if a response is currently in process, false if not.
