# KSP 示例程序

## 得到所有成员函数

```KOTLIN
fun KSClassDeclaration.getDeclaredFunctions(): Sequence<KSFunctionDeclaration> =
    declarations.filterIsInstance<KSFunctionDeclaration>()
```

## 检查一个类或函数是否为 local

```KOTLIN
fun KSDeclaration.isLocal(): Boolean =
    parentDeclaration != null && parentDeclaration !is KSClassDeclaration
```

## 查找类型别名指向的实际的类或接口声明

```KOTLIN
fun KSTypeAlias.findActualType(): KSClassDeclaration {
    val resolvedType = this.type.resolve().declaration
    return if (resolvedType is KSTypeAlias) {
        resolvedType.findActualType()
    } else {
        resolvedType as KSClassDeclaration
    }
}
```

## 在源代码文件的注解中查找被压制(Suppressed)的名称

```KOTLIN
// @file:kotlin.Suppress("Example1", "Example2")
fun KSFile.suppressedNames(): Sequence<String> = annotations
    .filter {
        it.shortName.asString() == "Suppress" &&
        it.annotationType.resolve().declaration.qualifiedName?.asString() == "kotlin.Suppress"
    }.flatMap {
        it.arguments.flatMap {
            (it.value as Array<String>).toList()
        }
    }
```
