类 Property

java.lang.Object
cn.taketoday.reflect.Property
所有已实现的接口:
Serializable, AnnotatedElement, Member
public class Property extends Object implements Member, AnnotatedElement, Serializable
A description of a JavaBeans Property that allows us to avoid a dependency on java.beans.PropertyDescriptor. The java.beans package is not available in a number of environments (e.g. Android, Java ME), so this is desirable for portability of core conversion facility.

Used to build a TypeDescriptor from a property location. The built TypeDescriptor can then be used to convert from/to the property type.

    • isInstance

      public boolean isInstance(Object value)
      Determines if the specified Object is assignment-compatible with the object represented by this Property. This method is the dynamic equivalent of the Java language instanceof operator. The method returns true if the specified Object argument is non-null and can be cast to the reference type represented by this Property object without raising a ClassCastException. It returns false otherwise.

      Specifically, if this Property object represents a declared class, this method returns true if the specified Object argument is an instance of the represented class (or of any of its subclasses); it returns false otherwise. If this Property object represents an array class, this method returns true if the specified Object argument can be converted to an object of the array class by an identity conversion or by a widening reference conversion; it returns false otherwise. If this Property object represents an interface, this method returns true if the class or any superclass of the specified Object argument implements this interface; it returns false otherwise. If this Property object represents a primitive type, this method returns false.

      参数:
      value - the object to check
      返回:
      true if obj is an instance of this property-type
