      org.apache.coyote.tomcat5.InputBuffer

InputBuffer
public class InputBuffer extends Reader implements ByteChunk.ByteInputChannel,CharChunk.CharInputChannel,CharChunk.CharOutputChannel(Code)
The buffer used by Tomcat request. This is a derivative of the Tomcat 3.3 OutputBuffer, adapted to handle input instead of output. This allows complete recycling of the facade objects (the ServletInputStream and the BufferedReader).

Field Detail
BYTE_STATE
final public int BYTE_STATE(Code)



CHAR_STATE
final public int CHAR_STATE(Code)



DEFAULT_BUFFER_SIZE
final public static int DEFAULT_BUFFER_SIZE(Code)



DEFAULT_ENCODING
final public static String DEFAULT_ENCODING(Code)



INITIAL_STATE
final public int INITIAL_STATE(Code)



conv
protected B2CConverter conv(Code)
Current byte to char converter.



debug
final static int debug(Code)



encoders
protected HashMap encoders(Code)
List of encoders.




Constructor Detail
InputBuffer
public InputBuffer()(Code)
Default constructor. Allocate the buffer with the default buffer size.



InputBuffer
public InputBuffer(int size)(Code)
Alternate constructor which allows specifying the initial buffer size.
Parameters:
  size - Buffer size to use




Method Detail
available
public int available() throws IOException(Code)



checkConverter
public void checkConverter() throws IOException(Code)



close
public void close() throws IOException(Code)
Close the input buffer.
throws:
  IOException - An underlying IOException occurred



getRequest
public Request getRequest()(Code)
Get associated Coyote request. the associated Coyote request



log
protected void log(String s)(Code)



mark
public void mark(int readAheadLimit) throws IOException(Code)



markSupported
public boolean markSupported()(Code)



read
public int read(byte[] b, int off, int len) throws IOException(Code)



read
public int read() throws IOException(Code)



read
public int read(char[] cbuf) throws IOException(Code)



read
public int read(char[] cbuf, int off, int len) throws IOException(Code)



readByte
public int readByte() throws IOException(Code)



ready
public boolean ready() throws IOException(Code)



realReadBytes
public int realReadBytes(byte cbuf, int off, int len) throws IOException(Code)
Reads new bytes in the byte chunk.
Parameters:
  buf - Byte buffer to be written to the response
Parameters:
  off - Offset
Parameters:
  cnt - Length
throws:
  IOException - An underlying IOException occurred



realReadChars
public int realReadChars(char cbuf, int off, int len) throws IOException(Code)



realWriteChars
public void realWriteChars(char c, int off, int len) throws IOException(Code)
Since the converter will use append, it is possible to get chars to be removed from the buffer for "writing". Since the chars have already been read before, they are ignored. If a mark was set, then the mark is lost.



recycle
public void recycle()(Code)
Recycle the output buffer.



reset
public void reset() throws IOException(Code)



setConverter
protected void setConverter() throws IOException(Code)



setEncoding
public void setEncoding(String s)(Code)



setRequest
public void setRequest(Request coyoteRequest)(Code)
Associated Coyote request.
Parameters:
  coyoteRequest - Associated Coyote request



skip
public long skip(long n) throws IOException(Code)
