示例1: it
it('should support blank literals', () => {
expect(emitStmt(o.literal(null).toStmt())).toEqual('(null as any);');
expect(emitStmt(o.literal(undefined).toStmt())).toEqual('(undefined as any);');
expect(emitStmt(o.variable('a', null).isBlank().toStmt())).toEqual('(a == null);');
});示例2: it
it('should read and write keys', () => {
expect(emitStmt(o.variable('someMap').key(o.variable('someKey')).toStmt()))
.toEqual(`someMap[someKey];`);
expect(emitStmt(o.variable('someMap').key(o.variable('someKey')).set(o.literal(1)).toStmt()))
.toEqual(`someMap[someKey] = 1;`);
});示例3: it
it('should support function statements', () => {
expect(emitStmt(new o.DeclareFunctionStmt('someFn', [], [])))
.toEqual(['void someFn() {', '}'].join('\n'));
expect(emitStmt(new o.DeclareFunctionStmt('someFn', [], [new o.ReturnStatement(o.literal(1))],
