LuciadFusionClass TLcdConcurrentBuffer

java.lang.Object

com.luciad.util.TLcdConcurrentBuffer

All Implemented Interfaces:

ILcdBuffer

public class TLcdConcurrentBuffer
extends Object
implements ILcdBuffer

This implementation of ILcdBuffer relies on java memory allocation and garbage collection. It doesn't share a single buffer but reallocates a new buffer each time a buffer segment is requested.

The size of allocated segments is only limited by the amount of available memory.

All the methods of the buffer segments provided by the class TLcdConcurrentBuffer are thread safe.

Method Detail

getByte

public byte[] getByte()
               throws UnsupportedOperationException

Not supported by this implementation.

Specified by:

getByte in interface ILcdBuffer

Returns:

NA

Throws:

UnsupportedOperationException - always thrown.

getSize

public int getSize()

This implementation always returns Integer.MAX_VALUE.

Specified by:

getSize in interface ILcdBuffer

Returns:

Integer.MAX_VALUE.

allocateBufferSegment

public ILcdBufferSegment allocateBufferSegment(int aCount)
                                        throws IllegalArgumentException

Description copied from interface: ILcdBuffer

Allocates a given number of bytes in this ILcdBuffer. Other buffer segments may be de-allocated as required to make space.

Specified by:

allocateBufferSegment in interface ILcdBuffer

Parameters:

aCount - the number of bytes to be allocated. It must not be larger than the total buffer size.

Returns:

an ILcdBufferSegment that specifies the allocated space in this ILcdBuffer.

Throws:

IllegalArgumentException - when the requested number of bytes is larger than the full buffer size.
