Method Summary

java.beans.BeanInfo	getBeanInfo() Returns the Java Bean information about all of the introspected bean properties, exposed methods, and events.
java.lang.Class<?>	getJavaClass() Returns the Java class about which this object managed information.
IJavaPropertyDescriptor	getPropertyDescriptor(java.lang.String name) Finds and returns the IJavaPropertyDescriptor for the property with the specified name.

Method Detail

getJavaClass

java.lang.Class<?> getJavaClass()

Returns the Java class about which this object managed information.

Returns:

Class the Java class

getBeanInfo

java.beans.BeanInfo getBeanInfo()

Returns the Java Bean information about all of the introspected bean properties, exposed methods, and events. This is a convenience method to access the BeanInfo that may be used by this class to find a Java Property.

Returns:

BeanInfo the BeanInfo for the managed class

getPropertyDescriptor

IJavaPropertyDescriptor getPropertyDescriptor(java.lang.String name)

Finds and returns the IJavaPropertyDescriptor for the property with the specified name. The following algorithm is used to find a property by the specified name:

1. Use bean introspection to find a property with the specified name. The property is expected to have a getter and/or setter method declared following the bean specification.
2. If not found via bean introspection, an attempt is made to find a public method with the same name. The property in that case is either read-only (method has a return value and no declared parameters) or is write-only (method has a single parameter and no return value)
3. If not found as a method, an attempt is made to find a field with the specified name (private/protected/public).

Parameters:

name - the name of the property

Returns:

IJavaPropertyDescriptor the descriptor for the property, null if no property with the specified name could be found
