DefaultMaxBytesRecvByteBufAllocator

public DefaultMaxBytesRecvByteBufAllocator()

DefaultMaxBytesRecvByteBufAllocator

public DefaultMaxBytesRecvByteBufAllocator(int maxBytesPerRead,
 int maxBytesPerIndividualRead)

Method Details

newHandle

public RecvByteBufAllocator.Handle newHandle()

Description copied from interface: RecvByteBufAllocator

Creates a new handle. The handle provides the actual operations and keeps the internal information which is required for predicting an optimal buffer capacity.

Specified by:

newHandle in interface RecvByteBufAllocator

maxBytesPerRead

public int maxBytesPerRead()

Description copied from interface: MaxBytesRecvByteBufAllocator

Returns the maximum number of bytes to read per read loop. a channelRead() event. If this value is greater than 1, an event loop might attempt to read multiple times to procure bytes.

Specified by:

maxBytesPerRead in interface MaxBytesRecvByteBufAllocator

maxBytesPerRead

public DefaultMaxBytesRecvByteBufAllocator maxBytesPerRead(int maxBytesPerRead)

Description copied from interface: MaxBytesRecvByteBufAllocator

Sets the maximum number of bytes to read per read loop. If this value is greater than 1, an event loop might attempt to read multiple times to procure bytes.

Specified by:

maxBytesPerRead in interface MaxBytesRecvByteBufAllocator

maxBytesPerIndividualRead

public int maxBytesPerIndividualRead()

Description copied from interface: MaxBytesRecvByteBufAllocator

Returns the maximum number of bytes to read per individual read operation. a channelRead() event. If this value is greater than 1, an event loop might attempt to read multiple times to procure bytes.

Specified by:

maxBytesPerIndividualRead in interface MaxBytesRecvByteBufAllocator

maxBytesPerIndividualRead

public DefaultMaxBytesRecvByteBufAllocator maxBytesPerIndividualRead(int maxBytesPerIndividualRead)

Description copied from interface: MaxBytesRecvByteBufAllocator

Sets the maximum number of bytes to read per individual read operation. If this value is greater than 1, an event loop might attempt to read multiple times to procure bytes.

Specified by:

maxBytesPerIndividualRead in interface MaxBytesRecvByteBufAllocator

maxBytesPerReadPair

public Map.Entry<Integer,Integer> maxBytesPerReadPair()

Description copied from interface: MaxBytesRecvByteBufAllocator

Atomic way to get the maximum number of bytes to read for a read loop and per individual read operation. If this value is greater than 1, an event loop might attempt to read multiple times to procure bytes.

Specified by:

maxBytesPerReadPair in interface MaxBytesRecvByteBufAllocator

Returns:

The Key is from MaxBytesRecvByteBufAllocator.maxBytesPerRead(). The Value is from MaxBytesRecvByteBufAllocator.maxBytesPerIndividualRead()

maxBytesPerReadPair

public DefaultMaxBytesRecvByteBufAllocator maxBytesPerReadPair(int maxBytesPerRead,
 int maxBytesPerIndividualRead)

Description copied from interface: MaxBytesRecvByteBufAllocator

Sets the maximum number of bytes to read for a read loop and per individual read operation. If this value is greater than 1, an event loop might attempt to read multiple times to procure bytes.

Specified by:

maxBytesPerReadPair in interface MaxBytesRecvByteBufAllocator

Parameters:

maxBytesPerRead - see MaxBytesRecvByteBufAllocator.maxBytesPerRead(int)

maxBytesPerIndividualRead - see MaxBytesRecvByteBufAllocator.maxBytesPerIndividualRead(int)
