Interface JXPathBeanInfo

  • All Superinterfaces:
    java.io.Serializable
    All Known Implementing Classes:
    JXPathBasicBeanInfo
    public interface JXPathBeanInfo
extends java.io.Serializable
    JXPathBeanInfo is similar to BeanInfo in that it describes properties of a JavaBean class. By default, JXPathBeanInfo classes are automatically generated by JXPathIntrospector 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.

    • Method Summary

      All Methods Instance Methods Abstract Methods 
      Modifier and Type Method Description
      java.lang.Class getDynamicPropertyHandlerClass()
      For dynamic objects, returns the class implementing the DynamicPropertyHandler interface.
      java.beans.PropertyDescriptor getPropertyDescriptor​(java.lang.String propertyName)
      Returns a PropertyDescriptor for the specified name or null if there is no such property.
      java.beans.PropertyDescriptor[] getPropertyDescriptors()
      Returns a list of property descriptors for the beans described by this bean info object.
      boolean isAtomic()
      Returns true if objects of this class are treated as atomic objects which have no properties of their own.
      boolean isDynamic()
      Returns true if the objects of this class have dynamic properties (e.g.

      • 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 and Number 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 and getDynamicPropertyHandlerClass() 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 the DynamicPropertyHandler interface. That class can be used to access dynamic properties.
        Returns:
        Class
