Detailed Description

Allocator base class and interface.

Implements part of the binary data layout by providing access to the stored elements. Not intended to be used by application code.

inlinevirtual

Update allocation of the dynamic elem at index to have newSize bytes.

The offset and size fields in the static section are updated as needed. Does not copy the old data to the new location.

Returns: the pointer to the elem at the new place, or nullptr if it was not moved.
