Class ReflectionProperty

Returns database specific options, if defined

interface User {
    logins: number & DatabaseField<{type: 'integer(8)'}>;

    //of for a specific db engine
    logins: number & Sqlite<{type: 'integer(8)'}>;
}

If undefined, it's not an embedded class.

If undefined the property is not an index. A unique property is defined as index with IndexOptions.unique=true.

Returns the ReflectionClass of the reference class/object literal.

Throws

Error if the property is not from type TypeClass or TypeObjectLiteral

Returns the sub type if available (for arrays for example).

Throws

Error if the property type does not support sub types.

Returns true when undefined or a missing value is allowed at the class itself. This is now only true when optional is set, but also when type is any.

If the property is actual optional or is an union with undefined in it.

Whether a value is required from serialization point of view. If this property has for example a default value (set via constructor or manually via t.default), then the value is not required to instantiate the property value.
