## Class ChunkedOutputStream

- java.lang.Object
- - java.io.OutputStream
  - - java.io.FilterOutputStream
    - - org.apache.commons.io.output.ChunkedOutputStream

- All Implemented Interfaces:
    Closeable, Flushable, AutoCloseable

      public class ChunkedOutputStream
      extends FilterOutputStream

  OutputStream which breaks larger output blocks into chunks. Native code may need to copy the input array; if the write buffer is very large this can cause OOME.
  Since:
    2.5

    - #### ChunkedOutputStream

          public ChunkedOutputStream(OutputStream stream,
                                     int chunkSize)

      Creates a new stream that uses the specified chunk size.
      Parameters:
        `stream` - the stream to wrap
        `chunkSize` - the chunk size to use; must be a positive number.
      Throws:
        `IllegalArgumentException` - if the chunk size is <= 0

    - #### ChunkedOutputStream

          public ChunkedOutputStream(OutputStream stream)

      Parameters:
        `stream` - the stream to wrap

  - ### Method Detail

    - #### write

          public void write(byte[] data,
                            int srcOffset,
                            int length)
                     throws IOException

      Writes the data buffer in chunks to the underlying stream
      Overrides:
        `write` in class `FilterOutputStream`
      Parameters:
        `data` - the data to write
        `srcOffset` - the offset
        `length` - the length of data to write
      Throws:
