Constructor Detail

Bufferback to summary
public Buffer(ByteBuffer container)

Creates a new FT_Matrix.Buffer instance backed by the specified container.

Changes to the container's content will be visible to the struct buffer instance and vice versa. The two buffers' position, limit, and mark values will be independent. The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer divided by FT_Matrix#SIZEOF, and its mark will be undefined.

The created buffer instance holds a strong reference to the container object.
