endNullable

@Nullable
public @Nullable BufferBuilder.BuiltBuffer endNullable()

Builds a buffer if there are vertices in the current batch and resets the building state.

Returns:

the built buffer if there are vertices, otherwise null

Throws:

IllegalStateException - if this builder has not begun building

end

public BufferBuilder.BuiltBuffer end()

Builds a buffer from the current batch and resets the building state.

Unlike endNullable(), this always builds a buffer even if there are no vertices in the current batch.
