Member Function Documentation

checkLifecycle()

void checkLifecycle ( )

inlineprivate

Test:

Allocation cluster grows when adding objects, but discards all objects at once when going out of scope, optionally also invoking (or not invoking) destructors.

Remarks

no destructors are invoked for any objects allocated through the createDisposable<TY>(args...) interface, or for allocations though the standard allocator adapter.

verifyInternals()

void verifyInternals ( )

inlineprivate

Test:

cover some tricky aspects of the low-level allocator

Remarks

due to the expected leverage of AllocationCluster, an optimised low-level approach was taken on various aspects of storage management; the additional metadata overhead is a power of two, exploiting contextual knowledge about layout; moreover, a special usage-mode allows to skip invocation of destructors. To document these machinations, change to internal data is explicitly verified here.

use_as_Allocator()

void use_as_Allocator ( )

inlineprivate

Test:

demonstrate use as Standard-Allocator

• define a vector, string and set to use the AllocationCluster as backend
• fill the vector with numbers and the set with random strings

Note

the extent size (hard coded as of 5/24) imposes a serious limitation regarding usable data structures; e.g. the std::deque immediately attempts to allocate a node buffer with >500 bytes, which is not supported by the current (rather simplistic) storage manager in AllocationCluster.

dynamicAdjustment()

void dynamicAdjustment ( )

inlineprivate

Test:

verify the ability to adjust the latest allocation dynamically.
