@brief Get the amount of vertices of the graph that share common properties.

graph._countCommonProperties(vertex1Example, vertex2Examples, options)

Similar to _commonProperties but returns count instead of the objects.

@EXAMPLES

A route planner example, all locations with the same properties:

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphModuleAmountProperties1} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("routeplanner"); graph._countCommonProperties({}, {}); ~ examples.dropGraph("routeplanner"); @END_EXAMPLE_ARANGOSH_OUTPUT

A route planner example, all German cities which share same properties except for population.

@EXAMPLE_ARANGOSH_OUTPUT{generalGraphModuleAmountProperties2} var examples = require("@arangodb/graph-examples/example-graph.js"); var graph = examples.loadGraph("routeplanner"); | graph._countCommonProperties({}, {}, {vertex1CollectionRestriction : 'germanCity', vertex2CollectionRestriction : 'germanCity' ,ignoreProperties: 'population'}); ~ examples.dropGraph("routeplanner"); @END_EXAMPLE_ARANGOSH_OUTPUT
