Having a buffer, that can auto expand on needs is a big plus for networking applications. To address this, IoBuffer has introduced the autoExpand property. It automatically expands its capacity and limit value.
WebbA byte buffer can be created in either one of the following ways: Allocate a new byte array and create a buffer based on it; Allocate a memory block and create a direct buffer based on it; Wrap an existing byte array to create a new buffer.

A byte buffer. This class defines six categories of operations upon byte buffers: Absolute and relative get and put methods that read and write single bytes; Relative bulk get methods that transfer contiguous … Visa mer A direct byte buffer may be created by invoking the allocateDirect factory method of this class. The buffers returned by this method typically have somewhat higher allocation and deallocation costs than non-direct buffers. The … Visa mer This class defines methods for reading and writing values of all other primitive types, except boolean.

The data is taken from an object and stored in buffer blocks for later consumption. To access the I/O mechanism, Java NIO provides channels as a gateway.FileChannel offers several advantages over the traditional Java I/O streams. diabetic foot podiatry
