Constructor Detail

HttpParser

public HttpParser(Buffer buffer,
                  HttpParser.EventHandler handler)

Constructor.

HttpParser

public HttpParser(Buffers buffers,
                  EndPoint endp,
                  HttpParser.EventHandler handler,
                  int headerBufferSize,
                  int contentBufferSize)

Constructor.

Parameters:

headerBufferSize - size in bytes of header buffer

contentBufferSize - size in bytes of content buffer

Method Detail

getContentLength

public long getContentLength()

getContentRead

public long getContentRead()

getState

public int getState()

inContentState

public boolean inContentState()

inHeaderState

public boolean inHeaderState()

isChunking

public boolean isChunking()

isIdle

public boolean isIdle()

Specified by:

isIdle in interface Parser

isComplete

public boolean isComplete()

Specified by:

isComplete in interface Parser

isMoreInBuffer

public boolean isMoreInBuffer()
                       throws IOException

Specified by:

isMoreInBuffer in interface Parser

Throws:

IOException

isState

public boolean isState(int state)

parse

public void parse()
           throws IOException

Parse until END state. If the parser is already in the END state, then it is reset and re-parsed.

Throws:

IllegalStateException - If the buffers have already been partially parsed.

IOException

parseAvailable

public long parseAvailable()
                    throws IOException

Parse until END state. This method will parse any remaining content in the current buffer. It does not care about the current state of the parser.

Specified by:

parseAvailable in interface Parser

Throws:

IOException

See Also:

parse(), parseNext()

parseNext

public long parseNext()
               throws IOException

Parse until next Event.

Throws:

IOException

fill

public long fill()
          throws IOException

fill the buffers from the endpoint

Throws:

IOException

skipCRLF

public void skipCRLF()

Skip any CRLFs in buffers

reset

public void reset(boolean returnBuffers)

Specified by:

reset in interface Parser

setState

public void setState(int state)

toString

public String toString(Buffer buf)

toString

public String toString()

Overrides:

toString in class Object

getHeaderBuffer

public Buffer getHeaderBuffer()

getBodyBuffer

public Buffer getBodyBuffer()

setForceContentBuffer

public void setForceContentBuffer(boolean force)

Parameters:

force - True if a new buffer will be forced to be used for content and the header buffer will not be used.
