Removes the property descriptors from the array by specified property names.

Parameters:

getPropertyDescriptor

public final java.beans.PropertyDescriptor getPropertyDescriptor(java.lang.String strProperty)

Gets the property descriptor with specified property name

Parameters:

strProperty - the name of the property

Returns:

the property descriptor with the specified name

getIndexedPropertyDescriptor

protected final java.beans.IndexedPropertyDescriptor getIndexedPropertyDescriptor(java.lang.String strProperty)

Gets the indexed property descriptor with specified property name

Parameters:

strProperty - the name of the property

Returns:

the indexed property descriptor with the specified name

getReadOnlyPropertyDescriptor

protected final java.beans.PropertyDescriptor getReadOnlyPropertyDescriptor(java.lang.String strProperty)

Gets the read only property descriptor with specified property name

getPropertyDescriptors

public java.beans.PropertyDescriptor[] getPropertyDescriptors()

Denies knowledge of properties.

Specified by:

getPropertyDescriptors in interface java.beans.BeanInfo

Overrides:

getPropertyDescriptors in class java.beans.SimpleBeanInfo

Returns:

An array of PropertyDescriptor describing the editable properties supported by this bean. May return null if the information should be obtained by automatic analysis. If a property is indexed, then its entry in the result array will belong to the IndexedPropertyDescriptor subclass of PropertyDescriptor. A client of getPropertyDescriptors can use "instanceof" to check if a given PropertyDescriptor is an IndexedPropertyDescriptor. A subclass of this class should override this method

getEventSetDescriptors

public java.beans.EventSetDescriptor[] getEventSetDescriptors()

Deny knowledge of event sets.

Specified by:

getEventSetDescriptors in interface java.beans.BeanInfo

Overrides:

getEventSetDescriptors in class java.beans.SimpleBeanInfo

Returns:

An array of EventSetDescriptors describing the kinds of events fired by this bean. May return null if the information should be obtained by automatic analysis.

getMethodDescriptors

Deny knowledge of methods.

Specified by:

getMethodDescriptors in interface java.beans.BeanInfo

Overrides:

getMethodDescriptors in class java.beans.SimpleBeanInfo

Returns:

An array of MethodDescriptors describing the externally visible methods supported by this bean. May return null if the information should be obtained by automatic analysis.

getBeanDescriptor

public java.beans.BeanDescriptor getBeanDescriptor()

Denies knowledge about the class and customizer of the bean

Specified by:

getBeanDescriptor in interface java.beans.BeanInfo

Overrides:

getBeanDescriptor in class java.beans.SimpleBeanInfo

Returns:

BeanDescriptor providing overall information about the bean, such as its displayName, its customizer, etc. May return null if the information should be obtained by automatic analysis

createBeanDescriptor

public static java.beans.BeanDescriptor createBeanDescriptor(java.lang.Class beanClass)

Create a BeanDescriptor for a bean that doesn't have a customizer.

Parameters:

beanClass - The Class object of the Java class that implements the bean.

Returns:

a BeanDescriptor object

createBeanDescriptor

                                                             java.lang.Class customizerClass)

Create a BeanDescriptor for a bean that has a customizer.

Parameters:

customizerClass - The Class object of the Java class that implements the bean's Customizer.

Returns:

a BeanDescriptor object

createBeanDescriptor

public static java.beans.BeanDescriptor createBeanDescriptor(java.lang.Class beanClass,
                                                             java.lang.Class customizerClass,

customizerClass - The Class object of the Java class that implements the bean's Customizer.

Returns:

a BeanDescriptor object

getIcon

public java.awt.Image getIcon(int iconKind)

This method returns an image object that can be used to represent the bean in toolboxes, toolbars, etc. Icon images will be GIFs, override this method to return other formats. We recommend that icons have a "transparent" background so they can be rendered onto an existing background. There are four possible flavors of icons (16x16 color, 32x32 color, 16x16 mono, 32x32 mono). If a bean choses to only support a single icon we recommend supporting 16x16 color. Each icon has the name as "Bean Name"+"Icon" (as Text) +"Icon Type", as an example Test bean has the 16x16 color icon called as "TestIconColor16.gif". If only one icon is specified it has the name as "Bean Name" + "Icon" (as Text) as an example "TestIcon.gif".

Specified by:

getIcon in interface java.beans.BeanInfo

Overrides:

getIcon in class java.beans.SimpleBeanInfo

Parameters:

iconKind - - The kind of icon requested. This should be one of the constant values ICON_COLOR_16x16, ICON_COLOR_32x32, ICON_MONO_16x16, or ICON_MONO_32x32.

Returns:

An image object representing the requested icon. May return null if no suitable icon is available.

                                         java.lang.String imageName)

Creates the Resource Image for specified Class

init

protected abstract void init()

Initializes the Bean Info
