Syntax

ArenaMemoryResource
(
    std::size_t initialSize,
    std::size_t regionSize,
    float growthFactor,
    MemoryResource * upstream
)

Remarks

Regions = {initialSize, regionSize, regions[1] * growthFactor, regions[2] * growthFactor, ... , regions[n - 1] * growthFactor}

Parameters

Parameter	Description
initialSize	The size of the first allocated region from which allocation requests are served.
regionSize	When a memory region backing allocation requests has not enough free space to serve an allocation, an additional region is allocated for both the current and all subsequent allocations. This parameter denotes the size of these additionally allocated regions.
growthFactor	It describes by which factor should each subsequently allocated region be scaled, relative to the previous region. A list of possible region allocation would look like:
upstream	The backing memory region will be allocated using the given upstream MemoryResource.
