@alias MemoryCache
@constructor
@classdesc Provides a limited-size memory cache of key-value pairs. The meaning of size depends on usage.
Some instances of this class work in bytes while others work in counts. See the documentation for the
specific use to determine the size units.
@param {Number} capacity The cache's capacity.
@param {Number} lowWater The size to clear the cache to when its capacity is exceeded.
@throws {ArgumentError} If either the capacity is 0 or negative or the low-water value is greater than
or equal to the capacity or less than 1.
Constructs a memory cache of a specified size .
