How to use the @pixi/core.BatchDrawCall function in @pixi/core

currentTexture = nextTexture;

                if (nextTexture._batchEnabled !== TICK)
                {
                    if (textureCount === MAX_TEXTURES)
                    {
                        TICK++;

                        textureCount = 0;

                        if (currentGroup.size > 0)
                        {
                            currentGroup = DRAW_CALL_POOL.pop();
                            if (!currentGroup)
                            {
                                currentGroup = new BatchDrawCall();
                                currentGroup.textures = new BatchTextureArray();
                            }
                            this.drawCalls.push(currentGroup);
                        }

                        currentGroup.start = index;
                        currentGroup.size = 0;
                        currentGroup.textures.count = 0;
                        currentGroup.type = drawMode;
                    }

                    // TODO add this to the render part..
                    nextTexture.touched = 1;// touch;

                    nextTexture._batchLocation = textureCount;
                    nextTexture.wrapMode = 10497;
