All Implemented Interfaces:

IOSupplier<MemoryMappedFileInputStream>

Enclosing class:

MemoryMappedFileInputStream

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

Builds a new MemoryMappedFileInputStream.

For example:

MemoryMappedFileInputStream s = MemoryMappedFileInputStream.builder()
  .setPath(path)
  .setBufferSize(256 * 1024)
  .get();

Builder

public Builder()

Constructs a new builder of MemoryMappedFileInputStream.

Method Details

get

public MemoryMappedFileInputStream get()
                                throws IOException

Builds a new MemoryMappedFileInputStream.

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

This builder uses the following aspects:

• AbstractStreamBuilder.getPath() gets the target aspect.
• 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 converting to an Path using AbstractStreamBuilder.getPath().
