Constructor Detail

AbstractByteBufFactory

protected AbstractByteBufFactory()

Creates a new factory whose default ByteOrder is ByteOrder.BIG_ENDIAN.

AbstractByteBufFactory

protected AbstractByteBufFactory(ByteOrder defaultOrder)

Creates a new factory with the specified default ByteOrder.

Parameters:

defaultOrder - the default ByteOrder of this factory

Method Detail

getBuffer

public ByteBuf getBuffer(int capacity)

Description copied from interface: ByteBufFactory

Returns a ByteBuf with the specified capacity. This method is identical to getBuffer(getDefaultOrder(), capacity).

Specified by:

getBuffer in interface ByteBufFactory

Parameters:

capacity - the capacity of the returned ByteBuf

Returns:

a ByteBuf with the specified capacity, whose readerIndex and writerIndex are 0

getBuffer

public ByteBuf getBuffer(byte[] array,
                int offset,
                int length)

Description copied from interface: ByteBufFactory

Returns a ByteBuf whose content is equal to the sub-region of the specified array. Depending on the factory implementation, the returned buffer could wrap the array or create a new copy of the array. This method is identical to getBuffer(getDefaultOrder(), array, offset, length).

Specified by:

getBuffer in interface ByteBufFactory

Parameters:

array - the byte array

offset - the offset of the byte array

length - the length of the byte array

Returns:

a ByteBuf with the specified content, whose readerIndex and writerIndex are 0 and (length - offset) respectively

getDefaultOrder

public ByteOrder getDefaultOrder()

Description copied from interface: ByteBufFactory

Returns the default endianness of the ByteBuf which is returned by ByteBufFactory.getBuffer(int).

Specified by:

getDefaultOrder in interface ByteBufFactory

Returns:

the default endianness of the ByteBuf which is returned by ByteBufFactory.getBuffer(int)
