IfChain

구문

class IfChain

설명

The chain object Builder.if and If return, so .elif(...) and .else(...) read top to bottom in authored order. It is reached only through the call that starts a chain. Its methods extend the same if statement in place, pushed once on the first arm, so a chain without a trailing .else still emits a valid if / else if with no else block.

예제

If(p.idx.eq(1), () => {
  pos.assign(vec2(3, -1))
}).elif(p.idx.eq(2), () => {
  pos.assign(vec2(-1, 3))
})

생성자

new IfChain(private readonly parent: Builder, private readonly arms: Array<{ cond: Expr; body: Stmt[] }>, private readonly setElse: (body: Stmt[]) => void)

인스턴스 메서드

elif (cond: ReadonlyNode<'bool'>, body: (b: Builder) => ReadonlyNode | void): IfChain

Add an else if (cond) { body } arm. Returns the chain. A body that returns a value is rejected with SD0115, as for Builder.if.

else (body: (b: Builder) => ReadonlyNode | void): void

Add the else { body } block and end the chain. A body that returns a value is rejected with SD0115, as for Builder.if.
