I wonder if it is possible to create DataInputStream backed by a MappedByteBuffer instance ?
MappedByteBuffer buff = (initialize...);
ByteArrayInputStream bis = new ByteArrayInputStream(buff.array());
This code snippet throws UnsupportedOperationException because mapped byte buffer is not backed by an accessible array.
Then I tried to load bytes to pyhsical memory by calling load method by it is no use.
Any suggestions ?
You can override methods in DataInputStream to use the MappedByteBuffer.
However, the simplest approach is to use the MappedByteBuffer directly as it support almost all the same methods.
