WeakMap (fantomas)

WeakMap Module

Function or value	Description
`cacheConditionally shouldCache valueFactory` Full Usage: `cacheConditionally shouldCache valueFactory` Parameters: shouldCache : `'Value -> bool` valueFactory : `'Key -> 'Value` Returns: `'Key -> 'Value`	Like getOrCreate, but only cache the value if it satisfies the given predicate. shouldCache : `'Value -> bool` valueFactory : `'Key -> 'Value` Returns: `'Key -> 'Value`
`getOrCreate valueFactory` Full Usage: `getOrCreate valueFactory` Parameters: valueFactory : `'Key -> 'Value` Returns: `'Key -> 'Value`	Provides association of lazily-created values with arbitrary key objects. The associated value is created on first request and kept alive only while the key is strongly referenced elsewhere (backed by ConditionalWeakTable). Usage: let getValueFor = WeakMap.getOrCreate (fun key -> expensiveInit key) let v = getValueFor someKey valueFactory : `'Key -> 'Value` Returns: `'Key -> 'Value`
