## Class ByteString.Output

- java.lang.Object
- - java.io.OutputStream
  - - com.google.protobuf.ByteString.Output

- All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
  Enclosing class:
    ByteString

      public static final class ByteString.Output
      extends java.io.OutputStream

  Outputs to a `ByteString` instance. Call `toByteString()` to create the `ByteString` instance.

    Modifier and Type | Method and Description
    --- | ---
    `void` | `reset()` Resets this stream, so that all currently accumulated output in the output stream is discarded.
    `int` | `size()` Returns the current size of the output stream.
    `ByteString` | `toByteString()` Creates a byte string.
    `java.lang.String` | `toString()`
    `void` | `write(byte[] b, int offset, int length)`
    `void` | `write(int b)`

- - ### Method Detail

    - #### write

          public void write(int b)

      Specified by:
        `write` in class `java.io.OutputStream`

    - #### write

          public void write(byte[] b,
                   int offset,
                   int length)

      Overrides:
        `write` in class `java.io.OutputStream`

    - #### toByteString

          public ByteString toByteString()

      Creates a byte string. Its size is the current size of this output stream and its output has been copied to it.
      Returns:
        the current contents of this output stream, as a byte string.

    - #### writeTo

          public void writeTo(java.io.OutputStream out)
                       throws java.io.IOException

      Writes the complete contents of this byte array output stream to the specified output stream argument.
      Parameters:
        `out` - the output stream to which to write the data.
      Throws:
        `java.io.IOException` - if an I/O error occurs.

    - #### size

          public int size()

      Returns the current size of the output stream.
      Returns:
        the current size of the output stream

    - #### reset

          public void reset()

      Resets this stream, so that all currently accumulated output in the output stream is discarded. The output stream can be used again, reusing the already allocated buffer space.

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`
