IByteBuffer

All Known Implementing Classes:

InByteBuffer

public interface IInByteBuffer
extends IByteBuffer

Input buffer interface. This extends the basic byte array buffer interface with methods specifically for input. Client code needs to obey the access rules stated in the method documentation, including the documentation for the base interface methods.

Method Detail

require

boolean require(int size)
                throws java.io.IOException

Require some number of bytes of data. When this call is made the buffer can discard all data up to the current offset, and may move retained data within the buffer array and read more data from the data source to make the requested number of bytes available. This call may cause the byte array buffer to be replaced, so IByteBuffer.getBuffer(), getLimit(), and IByteBuffer.getOffset() must all be called again before any further use of the buffer.

Parameters:

size - desired number of bytes

Returns:

true if request satisfied, false if end with less than request available

Throws:

java.io.IOException

getLimit

int getLimit()

Get offset past the end of data in buffer.

Returns:

offset past end of data
