io.objectbox.flatbuffers.FlatBufferBuilder.ByteBufferFactory

Direct Known Subclasses:

FlatBufferBuilder.HeapByteBufferFactory

Enclosing class:

FlatBufferBuilder

public abstract static class FlatBufferBuilder.ByteBufferFactory
extends Object

An interface that provides a user of the FlatBufferBuilder class the ability to specify the method in which the internal buffer gets allocated. This allows for alternatives to the default behavior, which is to allocate memory for a new byte-array backed `ByteBuffer` array inside the JVM. The FlatBufferBuilder class contains the HeapByteBufferFactory class to preserve the default behavior in the event that the user does not provide their own implementation of this interface.

ByteBufferFactory

public ByteBufferFactory()

Method Details

newByteBuffer

public abstract ByteBuffer newByteBuffer(int capacity)

Create a `ByteBuffer` with a given capacity. The returned ByteBuf must have a ByteOrder.LITTLE_ENDIAN ByteOrder.

Parameters:

capacity - The size of the `ByteBuffer` to allocate.

Returns:

Returns the new `ByteBuffer` that was allocated.

releaseByteBuffer

public void releaseByteBuffer(ByteBuffer bb)

Release a ByteBuffer. Current FlatBufferBuilder released any reference to it, so it is safe to dispose the buffer or return it to a pool. It is not guaranteed that the buffer has been created with newByteBuffer(int).

Parameters:

bb - the buffer to release
