Constructor Details

SpdyHttpDecoder

public SpdyHttpDecoder(SpdyVersion version,
 int maxContentLength)

Creates a new instance.

Parameters:

version - the protocol version

maxContentLength - the maximum length of the message content. If the length of the message content exceeds this value, a TooLongFrameException will be raised.

SpdyHttpDecoder

@Deprecated
public SpdyHttpDecoder(SpdyVersion version,
 int maxContentLength,
 boolean validateHeaders)

Deprecated.

Use the SpdyHttpDecoder(SpdyVersion, int, Map, HttpHeadersFactory, HttpHeadersFactory) constructor instead.

Creates a new instance.

Parameters:

version - the protocol version

maxContentLength - the maximum length of the message content. If the length of the message content exceeds this value, a TooLongFrameException will be raised.

validateHeaders - true if http headers should be validated

SpdyHttpDecoder

protected SpdyHttpDecoder(SpdyVersion version,
 int maxContentLength,
 Map<Integer,FullHttpMessage> messageMap)

Creates a new instance with the specified parameters.

Parameters:

version - the protocol version

maxContentLength - the maximum length of the message content. If the length of the message content exceeds this value, a TooLongFrameException will be raised.

messageMap - the Map used to hold partially received messages.

SpdyHttpDecoder

@Deprecated
protected SpdyHttpDecoder(SpdyVersion version,
 int maxContentLength,
 Map<Integer,FullHttpMessage> messageMap,
 boolean validateHeaders)

Deprecated.

Use the SpdyHttpDecoder(SpdyVersion, int, Map, HttpHeadersFactory, HttpHeadersFactory) constructor instead.

Creates a new instance with the specified parameters.

Parameters:

version - the protocol version

maxContentLength - the maximum length of the message content. If the length of the message content exceeds this value, a TooLongFrameException will be raised.

messageMap - the Map used to hold partially received messages.

validateHeaders - true if http headers should be validated

SpdyHttpDecoder

protected SpdyHttpDecoder(SpdyVersion version,
 int maxContentLength,
 Map<Integer,FullHttpMessage> messageMap,
 HttpHeadersFactory headersFactory,
 HttpHeadersFactory trailersFactory)

Creates a new instance with the specified parameters.

Parameters:

version - the protocol version

maxContentLength - the maximum length of the message content. If the length of the message content exceeds this value, a TooLongFrameException will be raised.

messageMap - the Map used to hold partially received messages.

headersFactory - The factory used for creating HTTP headers
