C++ (Cpp) setNULL Examples

Example #1

File: script_value.cpp Project: MaddTheSane/scummvm

void ScValue::setNative(BaseScriptable *val, bool persistent) {
	if (_type == VAL_VARIABLE_REF) {
		_valRef->setNative(val, persistent);
		return;
	}

	if (val == nullptr) {
		setNULL();
	} else {
		if (_valNative && !_persistent) {
			_valNative->_refCount--;
			if (_valNative->_refCount <= 0) {
				if (_valNative != val) {
					delete _valNative;
				}
				_valNative = nullptr;
			}
		}

		_type = VAL_NATIVE;
		_persistent = persistent;

		_valNative = val;
		if (_valNative && !_persistent) {
			_valNative->_refCount++;
		}
	}
}

Example #2

File: tile_map.hpp Project: iliis/A10

	TileMap(int w, int h, int tile_w, int tile_h, TileSet* ts)
	 : size(w,h), tile_size(tile_w, tile_h),
	   start_pos(0,0), tiles(ts)
	{
		assert(w>0 and h>0);
		assert(tile_w>0 and tile_h>0);
		assert(tiles);

		data = new Tile*  [size.x * size.y];

		setNULL(data, size.x * size.y);
	};
