Detailed Description

template<typename HeapPolicy, typename RefcountPolicy, typename TransiencePolicy = get_transience_policy_t<RefcountPolicy>, bool PreferFewerBiggerObjects = get_prefer_fewer_bigger_objects_v<HeapPolicy>, bool UseTransientRValues = get_use_transient_rvalues_v<RefcountPolicy>>
struct immer::memory_policy< HeapPolicy, RefcountPolicy, TransiencePolicy, PreferFewerBiggerObjects, UseTransientRValues >

This is a default implementation of a memory policy. A memory policy is just a bag of other policies plus some flags with hints to the user about the best way to use these strategies.

Template Parameters

HeapPolicy	A heap policy, for example, heap_policy.
RefcountPolicy	A reference counting policy, for example, refcount_policy.
TransiencePolicy	A transience policy, for example, no_transience_policy.
PreferFewerBiggerObjects	Boolean flag indicating whether the user should prefer to allocate memory in bigger chungs –e.g. by putting various objects in the same memory region– or not.
UseTransientRValues	Boolean flag indicating whether immutable containers should try to modify contents in-place when manipulating an r-value reference.
