类 BeanMap

  • 所有已实现的接口:
    java.util.Map
    public abstract class BeanMap
extends java.lang.Object
implements java.util.Map
    A Map-based view of a JavaBean. The default set of keys is the union of all property names (getters or setters). An attempt to set a read-only property will be ignored, and write-only properties will be returned as null. Removal of objects is not a supported (the key set is fixed).

      • create

        public static BeanMap create​(java.lang.Object bean)
        Helper method to create a new BeanMap. For finer control over the generated instance, use a new instance of BeanMap.Generator instead of this static method.
        参数:
        bean - the JavaBean underlying the map
        返回:
        a new BeanMap instance

      • newInstance

        public abstract BeanMap newInstance​(java.lang.Object bean)
        Create a new BeanMap instance using the specified bean. This is faster than using the create(java.lang.Object) static method.
        参数:
        bean - the JavaBean underlying the map
        返回:
        a new BeanMap instance

      • getPropertyType

        public abstract java.lang.Class getPropertyType​(java.lang.String name)
        Get the type of a property.
        参数:
        name - the name of the JavaBean property
        返回:
        the type of the property, or null if the property does not exist

      • get

        public java.lang.Object get​(java.lang.Object key)
        指定者:
        get 在接口中 java.util.Map

      • put

        public java.lang.Object put​(java.lang.Object key,
                            java.lang.Object value)
        指定者:
        put 在接口中 java.util.Map

      • get

        public abstract java.lang.Object get​(java.lang.Object bean,
                                     java.lang.Object key)
        Get the property of a bean. This allows a BeanMap to be used statically for multiple beans--the bean instance tied to the map is ignored and the bean passed to this method is used instead.
        参数:
        bean - the bean to query; must be compatible with the type of this BeanMap
        key - must be a String
        返回:
        the current value, or null if there is no matching property

      • put

        public abstract java.lang.Object put​(java.lang.Object bean,
                                     java.lang.Object key,
                                     java.lang.Object value)
        Set the property of a bean. This allows a BeanMap to be used statically for multiple beans--the bean instance tied to the map is ignored and the bean passed to this method is used instead.
        参数:
        key - must be a String
        返回:
        the old value, if there was one, or null

      • setBean

        public void setBean​(java.lang.Object bean)

        getBean()
