Slow LatLng.hashCode() performance #9

Closed GoogleCodeExporter closed 2 years ago

GoogleCodeExporter commented 9 years ago 
The LatLng.hashCode() use formatting, string concatenation and 
String.hashCode() to produce hash code for LatLng with good distribution.

However, this is slow and takes time even when there is no changes to the 
LatLng value.

A simple way to improve it is by caching the hash code instead of 
recalculation, similar to the way String.hashCode() works.

See this as a suggested solution:

Thanks.
