See java.beans.FeatureDescriptor.

public static Collection<? extends PropertyDescriptor>

Returns:

a collection of property descriptors
determineBasicProperties(Class<?>
the target class to introspect
beanClass)

Simple introspection algorithm for basic set/get/is accessor methods, building corresponding JavaBeans property descriptors for them.

public static boolean
equals(PropertyDescriptor pd, PropertyDescriptor otherPd)

Compare the given PropertyDescriptors and return true if they are equivalent, i.e. their read method, write method, property type, property editor and flags are equivalent.

determineBasicPropertiesback to summary
public static Collection<? extends PropertyDescriptor> determineBasicProperties(Class<?> beanClass) throws IntrospectionException

Simple introspection algorithm for basic set/get/is accessor methods, building corresponding JavaBeans property descriptors for them.

This just supports the basic JavaBeans conventions, without indexed properties or any customizers, and without other BeanInfo metadata. For standard JavaBeans introspection, use the JavaBeans Introspector.

Parameters
beanClass:Class<?>

the target class to introspect

Returns:Collection<? extends PropertyDescriptor>

a collection of property descriptors

Exceptions
IntrospectionException:
from introspecting the given bean class
