Class InputBuffer

java.io.Reader

org.apache.catalina.connector.InputBuffer

All Implemented Interfaces:

Closeable, AutoCloseable, Readable, org.glassfish.grizzly.http.util.ByteChunk.ByteInputChannel, org.glassfish.grizzly.http.util.CharChunk.CharInputChannel, org.glassfish.grizzly.http.util.CharChunk.CharOutputChannel

public class InputBuffer
extends Reader
implements org.glassfish.grizzly.http.util.ByteChunk.ByteInputChannel, org.glassfish.grizzly.http.util.CharChunk.CharInputChannel, org.glassfish.grizzly.http.util.CharChunk.CharOutputChannel

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).

Constructor Detail

InputBuffer

public InputBuffer()

Default constructor. Allocate the buffer with the default buffer size.

InputBuffer

public InputBuffer(int size)

Alternate constructor which allows specifying the initial buffer size.

Parameters:

size - Buffer size to use

Method Detail

setRequest

public void setRequest(org.glassfish.grizzly.http.server.Request grizzlyRequest)

Associated Grizzly request.

Parameters:

grizzlyRequest - Associated Grizzly request

setRequest

public void setRequest(Request request)

getRequest

public org.glassfish.grizzly.http.server.Request getRequest()

Get associated Grizzly request.

Returns:

the associated Grizzly request

recycle

public void recycle()

Recycle the output buffer.

close

public void close()
           throws IOException

Close the input buffer.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in class Reader

Throws:

IOException - An underlying IOException occurred

available

public int available()
              throws IOException

Throws:

IOException

realReadBytes

public int realReadBytes(byte[] cbuf,
                         int off,
                         int len)
                  throws IOException

Reads new bytes in the byte chunk.

Specified by:

realReadBytes in interface org.glassfish.grizzly.http.util.ByteChunk.ByteInputChannel

Parameters:

cbuf - Byte buffer to be written to the response

off - Offset

len - Length

Throws:

IOException - An underlying IOException occurred

readByte

public int readByte()
             throws IOException

Throws:

IOException

read

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

Throws:

IOException

isFinished

public boolean isFinished()

isReady

public boolean isReady()

setReadListener

public void setReadListener(javax.servlet.ReadListener readListener)

realWriteChars

public void realWriteChars(char[] c,
                           int off,
                           int len)
                    throws IOException

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.

Specified by:

realWriteChars in interface org.glassfish.grizzly.http.util.CharChunk.CharOutputChannel

Throws:

IOException

setEncoding

public void setEncoding(String encoding)
