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();
 

Since:

2.12.0

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
