Class: DirtyTrackingPositionMap
Defined in: packages/core/src/layers/RTLSLayer.ts:37
Drop-in replacement for new Map<string, PositionUpdate>() that tracks a version counter so rAF loops can detect "nothing changed since last frame" and skip redundant rendering work. Used by <RTLSLayer>/<BlueDot> wherever they own the PositionMap ref that adapter events write into.

get()
get(
key):PositionUpdate|undefined
Defined in: node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es2015.collection.d.ts:34
Returns a specified element from the Map object. If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.
Parameters
key
string
Returns
PositionUpdate | undefined
Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.
