Method Detail

isMultipart

public boolean isMultipart()

True if this request is a Multipart request

Returns:

True if this request is a Multipart request

getBodyHttpDatas

public List<InterfaceHttpData> getBodyHttpDatas()
                                         throws HttpPostRequestDecoder.NotEnoughDataDecoderException

This method returns a List of all HttpDatas from body.
If chunked, all chunks must have been offered using offer() method. If not, NotEnoughDataDecoderException will be raised.

Returns:

the list of HttpDatas from Body part for POST method

Throws:

HttpPostRequestDecoder.NotEnoughDataDecoderException - Need more chunks

getBodyHttpDatas

public List<InterfaceHttpData> getBodyHttpDatas(String name)
                                         throws HttpPostRequestDecoder.NotEnoughDataDecoderException

This method returns a List of all HttpDatas with the given name from body.
If chunked, all chunks must have been offered using offer() method. If not, NotEnoughDataDecoderException will be raised.

Returns:

All Body HttpDatas with the given name (ignore case)

Throws:

HttpPostRequestDecoder.NotEnoughDataDecoderException - need more chunks

getBodyHttpData

public InterfaceHttpData getBodyHttpData(String name)
                                  throws HttpPostRequestDecoder.NotEnoughDataDecoderException

This method returns the first InterfaceHttpData with the given name from body.
If chunked, all chunks must have been offered using offer() method. If not, NotEnoughDataDecoderException will be raised.

Returns:

The first Body InterfaceHttpData with the given name (ignore case)

Throws:

HttpPostRequestDecoder.NotEnoughDataDecoderException - need more chunks

offer

public void offer(HttpChunk chunk)
           throws HttpPostRequestDecoder.ErrorDataDecoderException

Initialized the internals from a new chunk

Parameters:

chunk - the new received chunk

Throws:

HttpPostRequestDecoder.ErrorDataDecoderException - if there is a problem with the charset decoding or other errors

hasNext

public boolean hasNext()
                throws HttpPostRequestDecoder.EndOfDataDecoderException
