org.apache.commons.io.input.BufferedFileChannelInputStream.Builder

All Implemented Interfaces:

IOSupplier<BufferedFileChannelInputStream>

Enclosing class:

BufferedFileChannelInputStream

public static class BufferedFileChannelInputStream.Builder
extends AbstractStreamBuilder<BufferedFileChannelInputStream, BufferedFileChannelInputStream.Builder>

Builds a new BufferedFileChannelInputStream.

Using File IO:

BufferedFileChannelInputStream s = BufferedFileChannelInputStream.builder()
  .setFile(file)
  .setBufferSize(4096)
  .get();

Using NIO Path:

BufferedFileChannelInputStream s = BufferedFileChannelInputStream.builder()
  .setPath(path)
  .setBufferSize(4096)
  .get();

get

public BufferedFileChannelInputStream get()
                                   throws IOException

Builds a new BufferedFileChannelInputStream.

You must set input that supports AbstractStreamBuilder.getInputStream(), otherwise, this method throws an exception.

This builder use the following aspects:

• AbstractStreamBuilder.getInputStream()
• AbstractStreamBuilder.getBufferSize()

Returns:

a new instance.

Throws:

IllegalStateException - if the origin is null.

UnsupportedOperationException - if the origin cannot be converted to a Path.

IOException - If an I/O error occurs

• AbstractStreamBuilder.getPath()
• AbstractStreamBuilder.getBufferSize()

setFileChannel

public BufferedFileChannelInputStream.Builder setFileChannel(FileChannel fileChannel)

Sets the file channel.

This setting takes precedence over all others.

Parameters:

fileChannel - the file channel.

Returns:

this instance.
