在下文中一共展示了Graph類的2個代碼示例,這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚,您的評價將有助於係統推薦出更棒的TypeScript代碼示例。

示例1: suite

suite('Graph', () => {
	var graph: Graph<string>;

	setup(() => {
		graph = new Graph<string>(s => s);
	});

	test('cannot be traversed when empty', function() {
		graph.traverse('foo', true, () => assert(false));
		graph.traverse('foo', false, () => assert(false));
		assert(true);
	});

	test('is possible to lookup nodes that don\'t exist', function() {
		assert.deepEqual(graph.lookup('ddd'), null);
	});

	test('inserts nodes when not there yet', function() {
		assert.deepEqual(graph.lookup('ddd'), null);
		assert.deepEqual(graph.lookupOrInsertNode('ddd').data, 'ddd');
		assert.deepEqual(graph.lookup('ddd').data, 'ddd');
	});

	test('can remove nodes and get length', function() {
		assert.equal(graph.length, 0);
		assert.deepEqual(graph.lookup('ddd'), null);
		assert.deepEqual(graph.lookupOrInsertNode('ddd').data, 'ddd');
		assert.equal(graph.length, 1);
		graph.removeNode('ddd');
		assert.deepEqual(graph.lookup('ddd'), null);
		assert.equal(graph.length, 0);
	});

	test('traverse from leaf', function() {
		graph.insertEdge('foo', 'bar');
		graph.traverse('bar', true, (node) => assert.equal(node, 'bar'));
		var items = ['bar', 'foo'];
		graph.traverse('bar', false, (node) => assert.equal(node, items.shift()));
	});

	test('traverse from center', function() {
		graph.insertEdge('1', '3');
		graph.insertEdge('2', '3');
		graph.insertEdge('3', '4');
		graph.insertEdge('3', '5');

		var items = ['3', '4', '5'];
		graph.traverse('3', true, (node) => assert.equal(node, items.shift()));

		var items = ['3', '1', '2'];
		graph.traverse('3', false, (node) => assert.equal(node, items.shift()));
	});

	test('traverse a chain', function() {
		graph.insertEdge('1', '2');
		graph.insertEdge('2', '3');
		graph.insertEdge('3', '4');
		graph.insertEdge('4', '5');

		var items = ['1', '2', '3', '4', '5'];
		graph.traverse('1', true, (node) => assert.equal(node, items.shift()));

		var items = ['1', '2', '3', '4', '5'].reverse();
		graph.traverse('5', false, (node) => assert.equal(node, items.shift()));
	});

	test('root', function() {
		graph.insertEdge('1', '2');
		var roots = graph.roots();
		assert.equal(roots.length, 1);
		assert.equal(roots[0].data, '2');

		graph.insertEdge('2', '1');
		var roots = graph.roots();
		assert.equal(roots.length, 0);
	});

	test('root complex', function() {
		graph.insertEdge('1', '2');
		graph.insertEdge('1', '3');
		graph.insertEdge('3', '4');

		var roots = graph.roots();
		assert.equal(roots.length, 2);
		assert(['2', '4'].every(n => roots.some(node => node.data === n)));
	});
});
