kotlin的KType类型判断

函数参数等涉及到KType类型, 可以用它来判断是否某个类型.

我写了几个易用函数(属性):

 

fun KType.isClass(cls: KClass<*>): Boolean {
	return this.classifier == cls
}

val KType.isTypeString: Boolean get() = this.isClass(String::class)
val KType.isTypeInt: Boolean get() = this.isClass(Int::class) || this.isClass(java.lang.Integer::class)
val KType.isTypeLong: Boolean get() = this.isClass(Long::class) || this.isClass(java.lang.Long::class)
val KType.isTypeByte: Boolean get() = this.isClass(Byte::class) || this.isClass(java.lang.Byte::class)
val KType.isTypeShort: Boolean get() = this.isClass(Short::class) || this.isClass(java.lang.Short::class)
val KType.isTypeChar: Boolean get() = this.isClass(Char::class) || this.isClass(java.lang.Character::class)
val KType.isTypeBoolean: Boolean get() = this.isClass(Boolean::class) || this.isClass(java.lang.Boolean::class)
val KType.isTypeFloat: Boolean get() = this.isClass(Float::class) || this.isClass(java.lang.Float::class)
val KType.isTypeDouble: Boolean get() = this.isClass(Double::class) || this.isClass(java.lang.Double::class)
val KType.isTypeByteArray: Boolean get() = this.isClass(ByteArray::class)
