Constructor.

Parameters:
headerBufferSize - size in bytes of header buffer
contentBufferSize - size in bytes of content buffer
Method Detail

                       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

          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.

blockForContent

public Buffer blockForContent(long maxIdleTime)
                       throws IOException
Throws:
IOException
