Method Detail

add

public java.beans.PropertyDescriptor[] add(java.beans.PropertyDescriptor[] array1,

Gets the property descriptor from the array by specified property name.

Parameters:

array - the array of property descriptor

propName - the name of the property

Returns:

the property descriptor which name is propName if found in the array, otherwise null

removePropertyDescriptor

public java.beans.PropertyDescriptor[] removePropertyDescriptor(java.beans.PropertyDescriptor[] array,
                                                                java.lang.String propName)

Removes the property descriptor from the array by specified property name.

Parameters:

array - the array of property descriptor

propName - the name of the property

Returns:

the property descriptor array which name is propName if found in the array, otherwise null

removePropertyDescriptors

public java.beans.PropertyDescriptor[] removePropertyDescriptors(java.beans.PropertyDescriptor[] array,
                                                                 java.lang.String[] propNames)

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

Parameters:

array - the array of property descriptor

propNames - the names of the properties

Returns:

getPropertyDescriptor

protected 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

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

Gets the write only property descriptor with specified property name

Parameters:

strProperty - the name of the property

Returns:

the write only property descriptor with the specified name

getPropertyDescriptors

public abstract java.beans.PropertyDescriptor[] getPropertyDescriptors()

Denies knowledge of properties.

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

getBeanDescriptor

public abstract java.beans.BeanDescriptor getBeanDescriptor()

Denies knowledge about the class and customizer of the bean

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 A subclass of this class should override this method
