參數

name: String

屬性的名稱。 name 不能包含內嵌的 null。

attributes: PropertyAttributes

這個屬性 (Property) 的屬性 (Attribute)。

returnType: Type

屬性的傳回類型。

returnTypeRequiredCustomModifiers: Type[]

代表該屬性傳回類型之必要自訂修飾詞的類型陣列，例如 IsConst。如果傳回類型沒有必要的自訂修飾詞，則指定 null。

returnTypeOptionalCustomModifiers: Type[]

代表該屬性傳回型別之選擇性自訂修飾詞的類型陣列，例如 IsConst。如果傳回類型沒有選擇性的自訂修飾詞，則指定 null。

parameterTypes: Type[]

屬性的參數類型。

parameterTypeRequiredCustomModifiers: Type[][]

類型陣列的陣列。每個類型陣列都代表其對應參數必要的自訂修飾詞，例如 IsConst。如果特定的參數沒有必要的自訂修飾詞，則指定 null，而非類型陣列。如果這些參數都沒有必要的自訂修飾詞，則指定 null，而非陣列的陣列。

parameterTypeOptionalCustomModifiers: Type[][]

類型陣列的陣列。每個類型陣列都代表其對應參數的選擇性自訂修飾詞，例如 IsConst。如果特定的參數沒有選擇性的自訂修飾詞，則指定 null，而非類型陣列。如果這些參數都沒有選擇性的自訂修飾詞，則指定 null，而非陣列的陣列。
