Method Detail- 
writepublic final void write(int cc) throws java.io.IOExceptionWrite the data to the buffer and flush the buffer, if a line separator is detected.- Specified by:
- writein class- java.io.OutputStream
- Parameters:
- cc- data to log (byte).
- Throws:
- java.io.IOException- if there is an error.
 
 - 
flushpublic void flush() throws java.io.IOExceptionFlush this log stream- Specified by:
- flushin interface- java.io.Flushable
- Overrides:
- flushin class- java.io.OutputStream
- Throws:
- java.io.IOException- if there is an error.
 
 - 
processBufferprotected void processBuffer() throws java.io.IOExceptionConverts the buffer to a byte[] and sends it toprocessLine- Throws:
- java.io.IOException- if there is an error.
 
 - 
processLineprotected abstract void processLine(java.lang.String line) throws java.io.IOExceptionProcesses a line.- Parameters:
- line- the line to log.
- Throws:
- java.io.IOException- if there is an error.
 
 - 
processLineprotected void processLine(byte[] line) throws java.io.IOExceptionProcesses a line.This implementations invokes the string-arg version converting the byte array using the default encoding. Subclasses are encouraged to override this method (and provide a dummy implementation of the String-arg version) so they don't interfere with the encoding of the underlying stream. - Parameters:
- line- the line to log.
- Throws:
- java.io.IOException- if there is an error.
- Since:
- Ant 1.8.3
 
 - 
closepublic void close() throws java.io.IOExceptionWrites all remaining- Specified by:
- closein interface- java.lang.AutoCloseable
- Specified by:
- closein interface- java.io.Closeable
- Overrides:
- closein class- java.io.OutputStream
- Throws:
- java.io.IOException- if there is an error.
 
 - 
writepublic final void write(byte[] b, int off, int len) throws java.io.IOExceptionWrite a block of characters to the output stream- Overrides:
- writein class- java.io.OutputStream
- Parameters:
- b- the array containing the data
- off- the offset into the array where data starts
- len- the length of block
- Throws:
- java.io.IOException- if the data cannot be written into the stream.
