Conditions

Indoorgraphs offers robust condition functionality, allowing you to specify which paths and nodes to exclude when calculating a route.

Example data

To get started, consider the following simple graph consisting of two nodes that are linked to each other:

const data = {
    "nodes": {
        "UG_t1": {
            "coordinates": [
                6.967842553558049,
                50.946860664839846
            ],
            "attributes": {
                "wellLit": true,
                "doorWidth": "200"
            },
            "id": "UG_t1",
            "level": "UG",
            "adjacentNodes": [
                "UG_t2"
            ]
        },
        "UG_t2": {
            "coordinates": [
                6.968503094697883,
                50.94665193377298
            ],
            "attributes": {
                "wellLit": true,
                "doorWidth": "200"
            },
            "id": "UG_t2",
            "level": "UG",
            "adjacentNodes": [
                "UG_t1",
    
            ]
        }
    },
    "pathAttributes": {
        "UG_t2-UG_t1": {
            "pathWidth": "20"
        }
    }
}

Simple conditions The following query removes nodes with a doorWidth of 200:

graph.removeNodes([["doorWidth === 200"]]);

Query operators

• < less than

• <= less than or equal to

• === equal too

• > greater than

• >= greater than or equal to

• !== not equal to

Compound AND conditions

graph.removeNodes([["doorWidth === 200", "&&", "wellLit" === false]]);

OR conditions

graph.removeNodes([["doorWidth === 200", "||", "wellLit" === false]]);

Chain conditions
