Arena class

An Allocator which frees all allocations at the same time.

The arena allows you to allocate heap memory, but ignores calls to free. Instead you call releaseAll to release all the allocations at the same time.

Also allows other resources to be associated with the arena, through the using method, to have a release function called for them when the arena is released.

An Allocator can be provided to do the actual allocation and freeing. Defaults to using calloc.

Allocates memory and includes it in the arena.

override

free(Pointer<NativeType> pointer) → void

Does nothing, invoke releaseAll instead.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onReleaseAll(void releaseResourceCallback()) → void

Registers releaseResourceCallback to be executed on releaseAll.

releaseAll({bool reuse = false}) → void

Releases all resources that this Arena manages.

toString() → String

A string representation of this object.

inherited

using<T>(T resource, void releaseCallback(T)) → T

Registers resource in this arena.
