ContextAttribute Class
 

This API supports the product infrastructure and is not intended to be used directly from your code.

Provides the default implementations of the IContextAttribute and IContextProperty interfaces.

Constructors
NameDescription
System_CAPS_pubmethod ContextAttribute

This API supports the product infrastructure and is not intended to be used directly from your code. Creates an instance of the ContextAttribute class with the specified name.

Properties
NameDescription
System_CAPS_pubproperty

This API supports the product infrastructure and is not intended to be used directly from your code. Gets the name of the context attribute.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

Methods
NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a Boolean value indicating whether this instance is equal to the specified object.(Overrides AttributeEquals.)

System_CAPS_protmethod Finalize

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethod Freeze

This API supports the product infrastructure and is not intended to be used directly from your code. Called when the context is frozen.

System_CAPS_pubmethod GetHashCode

This API supports the product infrastructure and is not intended to be used directly from your code. Returns the hashcode for this instance of ContextAttribute.(Overrides AttributeGetHashCode.)

System_CAPS_pubmethod GetPropertiesForNewContext

This API supports the product infrastructure and is not intended to be used directly from your code. Adds the current context property to the given message.

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsContextOK

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a Boolean value indicating whether the context parameter meets the context attribute's requirements.

System_CAPS_pubmethod IsDefaultAttribute

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod IsNewContextOK

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a Boolean value indicating whether the context property is compatible with the new context.

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_protmethod MemberwiseClone

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

Fields
NameDescription
System_CAPS_protfield AttributeName

This API supports the product infrastructure and is not intended to be used directly from your code. Indicates the name of the context attribute.

Explicit Interface Implementations
NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

Remarks

The ContextAttribute class is the root for all context attributes. Simple Context class properties can be derived from ContextAttribute with the context attribute and the context property being in the class. For more specialized or more sophisticated needs, the context attribute can derive from ContextAttribute and the context property can be split into a separated class. For more information about using attributes, see Extending Metadata Using Attributes.

Notes to Inheritors:

The property must not be overridden in any user derived class. The current Equals and GetHashCode methods depend on the default functionality. To provide advanced behavior for a class extending the ContextAttribute class and override the property, you also have to override the default implementation of the Equals and GetHashCode methods.
