public:
 bool FilterAttributes(System::ComponentModel::IComponent ^ component, System::Collections::IDictionary ^ attributes);

public bool FilterAttributes (System.ComponentModel.IComponent component, System.Collections.IDictionary attributes);

abstract member FilterAttributes : System.ComponentModel.IComponent * System.Collections.IDictionary -> bool

Public Function FilterAttributes (component As IComponent, attributes As IDictionary) As Boolean

Parameters

component: IComponent

The component to filter the attributes of.

attributes: IDictionary

A dictionary of attributes that can be modified.

Returns

Boolean

true if the set of filtered attributes is to be cached; false if the filter service must query again.

Remarks

This method is called when a user requests a set of attributes for a component. The attributes are added to the dictionary with the attribute's TypeId as the keys and the actual attribute as the value. Implementers of this service can add, remove, or alter existing attribute entries in the dictionary.

Notes to Implementers

Return false only when necessary, because repeated queries to the type descriptor filter service can decrease performance.
