## Class LineOrientedOutputStream

- java.lang.Object
- - java.io.OutputStream
  - - org.apache.tools.ant.util.LineOrientedOutputStream

- All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
  Direct Known Subclasses:
    LineOrientedOutputStreamRedirector, LogOutputStream

      public abstract class LineOrientedOutputStream
      extends java.io.OutputStream

  Invokes `processLine` whenever a full line has been written to this stream.

  Tries to be smart about line separators.

  - ### Method Detail

    - #### write

          public final void write(int cc)
                           throws java.io.IOException

      Write the data to the buffer and flush the buffer, if a line separator is detected.
      Specified by:
        `write` in class `java.io.OutputStream`
      Parameters:
        `cc` - data to log (byte).
      Throws:
        `java.io.IOException` - if there is an error.

    - #### flush

          public void flush()
                     throws java.io.IOException

      Flush this log stream
      Specified by:
        `flush` in interface `java.io.Flushable`
      Overrides:
        `flush` in class `java.io.OutputStream`
      Throws:
        `java.io.IOException` - if there is an error.

    - #### processBuffer

          protected void processBuffer()
                                throws java.io.IOException

      Converts the buffer to a byte[] and sends it to `processLine`
      Throws:
        `java.io.IOException` - if there is an error.

    - #### processLine

          protected abstract void processLine(java.lang.String line)
                                       throws java.io.IOException

      Processes a line.
      Parameters:
        `line` - the line to log.
      Throws:
        `java.io.IOException` - if there is an error.

    - #### processLine

          protected void processLine(byte[] line)
                              throws java.io.IOException

      Processes 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

    - #### close

          public void close()
                     throws java.io.IOException

      Writes all remaining
      Specified by:
        `close` in interface `java.io.Closeable`
      Specified by:
        `close` in interface `java.lang.AutoCloseable`
      Overrides:
        `close` in class `java.io.OutputStream`
      Throws:
        `java.io.IOException` - if there is an error.

    - #### write

          public final void write(byte[] b,
                                  int off,

                           throws java.io.IOException

      Write a block of characters to the output stream
      Overrides:
        `write` in 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.
