Constructor Detail

JavaClassInfo

public JavaClassInfo(java.lang.Class<?> clz,
                     java.beans.BeanInfo beanInfo)

Constructor, creates a new JavaClassInfo record for the specified Java Class.

Parameters:

clz - the Java Class for which to manage information

beanInfo - the BeanInfo for the specified clz

Method Detail

getJavaClass

public java.lang.Class<?> getJavaClass()

Returns the Java class about which this object managed information.

Specified by:

getJavaClass in interface IJavaClassInfo

Returns:

Class the Java class

getBeanInfo

public 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.

Specified by:

getBeanInfo in interface IJavaClassInfo

Returns:

BeanInfo the BeanInfo for the managed class

getPropertyDescriptor

public 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).

Specified by:

getPropertyDescriptor in interface IJavaClassInfo

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

getBeanPropertyDescriptors

public java.util.List<IJavaPropertyDescriptor> getBeanPropertyDescriptors()
