Class calypso.util.ByteLineBuffer

java.lang.Object
   |
   +----calypso.util.ByteLineBuffer

This class is stores data in a private ByteBuf appending new data as needed, and returning line separated data.

public class  ByteLineBuffer
     extends java.lang.Object
{
          // Fields 5
     private static final boolean DEBUG;
     private ByteBuf buffer;
     private boolean buffer_full;
     private ByteBuf inputeol;
     private ByteBuf outputeol;

          // Constructors 1
     public ByteLineBuffer();

          // Methods 5
     public boolean pullLine(ByteBuf);
     public void pushBytes(ByteBuf);
     public void pushEOF();
     public void setInputEOL(ByteBuf);
     public void setOutputEOL(ByteBuf);
}

• DEBUG

   private static final boolean DEBUG

• buffer_full

   private boolean buffer_full

• buffer

   private ByteBuf buffer

• outputeol

   private ByteBuf outputeol

• inputeol

   private ByteBuf inputeol

• ByteLineBuffer

   public ByteLineBuffer() 

Constructs an empty ByteLineBuffer.

• pushBytes

   public void pushBytes(ByteBuf buf) 

Appends data to the end of the internal ByteBuf.

Parameter	Description
buf	data to append to internal buffer

• pushEOF

   public void pushEOF() 

indicates that the last piece of data is now present.

• setInputEOL

   public void setInputEOL(ByteBuf buf) 

Sets the EOL characters to look for in the incoming stream. Setting this to be null will cause it to look for any of , , or . Note that null (the default) could cause up to one extra to be held in the buffer (in the case where the last byte read from the underlying stream was , and no following byte (or EOF) has yet been read.)

• setOutputEOL

   public void setOutputEOL(ByteBuf buf) 

End of line characters & or any combination will be replaced by this string if it is present. Setting this to a zero length string will cause them to be stripped. Setting this to null will cause the EOL characters to be passed through unchanged (the default).

Parameter	Description
buf	ByteBuf representing EOL replacement string

• pullLine

   public boolean pullLine(ByteBuf buf) 

Returns a ByteBuf with a line of data which was separated by or any combination. Holds the last line in the ByteBuf until pushEOF() is called. If a ByteBuf containing data is sent in, the data is removed.

Parameter	Description
buf	single line of data in a ByteBuf

Returns:

true if a line was retrieved, false if not
