Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform.
In order to more clearly explain the above method for detecting a topological collision, a specific embodiment will be described below, however, it should be noted that this embodiment is only for better explaining the present invention and is not meant to limit the present invention unduly.
Device group drag collision detection:
when a device group is dragged, in a dragging event, a collision detection code is written to acquire all objects in a topology, the object arrays are circulated, points (comprising the device and the device group) and connecting lines are respectively placed in the two arrays, an object of a global point is set, and ids of all the points are used as object key values;
for example:
the method comprises the steps of circulating an array of all points, obtaining xy values of an upper left corner and a lower right corner of each point, obtaining equipment contained in the equipment set when the point is just the equipment set, recirculating the array of all points once, obtaining xy values of the upper left corner and the lower right corner of each point by inner circulation, adding an id of the point of the outer circulation to a corresponding array of an id of the point of the inner circulation as a key value pair to be placed in an object of a global point if the size of the point of the inner circulation contains the size of the point of the outer circulation, and adding all equipment contained in the equipment set obtained when the point of the outer circulation is the equipment set to the object of the global point and the value is an empty array;

the method comprises the steps that through dragging equipment in the equipment group, the width and the height of the equipment group are further enlarged or reduced, and when the equipment in the equipment group is dragged by us, the dragging events are bound to the equipment in the same way;
for example:
this.on('mousedown',this._dragStart,this)；
this.on('mousemove',this._drag,this)；
this.on('mouseup',this._dragEnd,this)；
