com.opencms.flex.cache
Class CmsFlexResponse.CmsServletOutputStream  

java.lang.Object
  java.io.OutputStream
      javax.servlet.ServletOutputStream
          com.opencms.flex.cache.CmsFlexResponse.CmsServletOutputStream

Enclosing class:

CmsFlexResponse

---

private class CmsFlexResponse.CmsServletOutputStream

extends javax.servlet.ServletOutputStream

Wrapped implementation of the ServletOutputStream.

This implementation writes to an internal buffer and optionally to another output stream at the same time. It should be fully transparent to the standard ServletOutputStream.

---

Field Summary
private static boolean	DEBUG           Debug flag
private  javax.servlet.ServletOutputStream	servletStream           The optional output stream to write to
private  java.io.ByteArrayOutputStream	stream           The internal steam buffer

 

Fields inherited from class javax.servlet.ServletOutputStream

 

Constructor Summary

CmsFlexResponse.CmsServletOutputStream()           Constructor that must be used if the stream should write only to a buffer.

CmsFlexResponse.CmsServletOutputStream(javax.servlet.ServletOutputStream servletStream)           Constructor that must be used if the stream should write to a buffer and to another stream at the same time.

 

Method Summary
void	clear()           Clears the buffer by initializing the buffer with a new stream.
void	flush()           This method forces any data that may have been buffered to be written to the underlying output device.
byte[]	getBytes()           Provides access to the bytes cached in the buffer.
void	write(byte[] b, int off, int len)           This method writes len bytes from the specified array b starting at index off into the array.
void	write(int b)           This method writes a single byte to the output stream.
void	writeToServletStream(byte[] b)           Writes an array of bytes only to the included servlet stream, not to the buffer.

Constructor Detail

CmsFlexResponse.CmsServletOutputStream

public CmsFlexResponse.CmsServletOutputStream()

Constructor that must be used if the stream should write only to a buffer.

---

CmsFlexResponse.CmsServletOutputStream

public CmsFlexResponse.CmsServletOutputStream(javax.servlet.ServletOutputStream servletStream)

Constructor that must be used if the stream should write to a buffer and to another stream at the same time.

Method Detail

write

public void write(int b)
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method writes a single byte to the output stream. The byte written is the low eight bits of the int passed and a argument.

Subclasses must provide an implementation of this abstract method

---

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method writes len bytes from the specified array b starting at index off into the array.

This method in this class calls the single byte write() method in a loop until all bytes have been written. Subclasses should override this method if possible in order to provide a more efficent implementation.

---

writeToServletStream

public void writeToServletStream(byte[] b)
                          throws java.io.IOException

Writes an array of bytes only to the included servlet stream, not to the buffer.

---

flush

public void flush()
           throws java.io.IOException

Description copied from class: java.io.OutputStream

This method forces any data that may have been buffered to be written to the underlying output device. Please note that the host environment might perform its own buffering unbeknowst to Java. In that case, a write made (for example, to a disk drive) might be cached in OS buffers instead of actually being written to disk.

This method in this class does nothing.

---

getBytes

public byte[] getBytes()

Provides access to the bytes cached in the buffer.

---

clear

public void clear()

Clears the buffer by initializing the buffer with a new stream.
