DEFAULT

public static final UnpooledByteBufAllocator DEFAULT

Default instance which uses leak-detection for direct buffers.

构造器详细资料

UnpooledByteBufAllocator

public UnpooledByteBufAllocator(boolean preferDirect)

Create a new instance which uses leak-detection for direct buffers.

参数:

preferDirect - true if AbstractByteBufAllocator.buffer(int) should try to allocate a direct buffer rather than a heap buffer

UnpooledByteBufAllocator

public UnpooledByteBufAllocator(boolean preferDirect,
                                boolean disableLeakDetector)

Create a new instance

参数:

preferDirect - true if AbstractByteBufAllocator.buffer(int) should try to allocate a direct buffer rather than a heap buffer

disableLeakDetector - true if the leak-detection should be disabled completely for this allocator. This can be useful if the user just want to depend on the GC to handle direct buffers when not explicit released.

UnpooledByteBufAllocator

                                boolean disableLeakDetector,
                                boolean tryNoCleaner)

Create a new instance

参数:

preferDirect - true if AbstractByteBufAllocator.buffer(int) should try to allocate a direct buffer rather than a heap buffer

disableLeakDetector - true if the leak-detection should be disabled completely for this allocator. This can be useful if the user just want to depend on the GC to handle direct buffers when not explicit released.

tryNoCleaner - true if we should try to use PlatformDependent.allocateDirectNoCleaner(int) to allocate direct memory.
