Method Detail

get

public MemoryMappedFileInputStream get()
                                throws java.io.IOException

Builds a new MemoryMappedFileInputStream.

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

This builder use the following aspects:

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

Returns:

a new instance.

Throws:

java.lang.IllegalStateException - if the origin is null.

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

java.io.IOException - if an I/O error occurs.
