Interface JXPathBeanInfo
-
- All Superinterfaces:
java.io.Serializable
- All Known Implementing Classes:
JXPathBasicBeanInfo
public interface JXPathBeanInfo extends java.io.Serializable
JXPathBeanInfo is similar toBeanInfo
in that it describes properties of a JavaBean class. By default, JXPathBeanInfo classes are automatically generated byJXPathIntrospector
based on the java.beans.BeanInfo. As with JavaBeans, the user can supply an alternative implementation of JXPathBeanInfo for a custom class. The alternative implementation is located by class name, which is the same as the name of the class it represents with the suffix "XBeanInfo". So, for example, if you need to provide an alternative JXPathBeanInfo class for class "com.foo.Bar", write a class "com.foo.BarXBeanInfo" and make it implement the JXPathBeanInfo interface.- Version:

Method Detail
-
isAtomic
boolean isAtomic()
Returns true if objects of this class are treated as atomic objects which have no properties of their own. For example,String
andNumber
are atomic.- Returns:
- boolean
-
isDynamic
boolean isDynamic()
Returns true if the objects of this class have dynamic properties (e.g. java.util.Map). If this method returns true,getPropertyDescriptors()
should return null andgetDynamicPropertyHandlerClass()
should return a valid class name. An object cannot have both static and dynamic properties at the same time.- Returns:
- boolean
-
getPropertyDescriptors
java.beans.PropertyDescriptor[] getPropertyDescriptors()
Returns a list of property descriptors for the beans described by this bean info object. Returns null for atomic beans.- Returns:
- PropertyDescriptor[]
-
getPropertyDescriptor
java.beans.PropertyDescriptor getPropertyDescriptor(java.lang.String propertyName)
Returns a PropertyDescriptor for the specified name or null if there is no such property.- Parameters:
propertyName
- property name- Returns:
- PropertyDescriptor
-
getDynamicPropertyHandlerClass
java.lang.Class getDynamicPropertyHandlerClass()
For dynamic objects, returns the class implementing theDynamicPropertyHandler
interface. That class can be used to access dynamic properties.- Returns:
- Class
