Detailed Description

Block-independent base class of BlockAllocator.

This class contains static methods which do not depend on the template parameters of BlockAllocator that are used to determine block/ type. This allows the methods to be defined in a separate source file and use macros that cannot be used in headers, e.g. PW_CHECK.

This class should not be used directly. Instead, use BlockAllocator or one of its specializations.

Member Function Documentation

◆ CrashOnAllocated()

static void pw::allocator::internal::GenericBlockAllocator::CrashOnAllocated ( void * allocated )

staticprotected

Crashes with an informational message that a given block is allocated.

This method is meant to be called by SplitFreeListAllocators destructor. There must not be any outstanding allocations from an when it is destroyed.

◆ CrashOnInvalidFree()

static void pw::allocator::internal::GenericBlockAllocator::CrashOnInvalidFree ( void * freed )

staticprotected

Crashes with an informational message that a given pointer does not belong to this allocator.
