FreezableAttribute Class |
Custom attribute that, when applied to a class, implements the FreezableThreadingModel to this class.
The aspect introduces the IFreezable interface into the target class. After the Freeze()
method has been invoked, the object can no longer be modified, and can therefore be safely shared between several threads.

public sealed class FreezableAttribute : ReadOnlyThreadAwareAttribute, IFreezable, IThreadAware
The FreezableAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
| FreezableAttribute | Initializes a new instance of the FreezableAttribute class |
| Name | Description | |
|---|---|---|
| AspectPriority |
Gets or sets the weaving priority of the aspect.
(Inherited from Aspect.) | |
| AttributeExclude |
If true, indicates that this attribute removes all other instances of the
same attribute type from the set of elements defined by the current instance.
(Inherited from MulticastAttribute.) | |
| AttributeInheritance |
Determines whether this attribute is inherited
(Inherited from MulticastAttribute.) | |
| AttributePriority |
Gets or sets the priority of the current attribute in case that multiple
instances are defined on the same element (lower values are processed before).
(Inherited from MulticastAttribute.) | |
| AttributeReplace |
Determines whether this attribute replaces other attributes found on the
target declarations.
(Inherited from MulticastAttribute.) | |
| AttributeTargetAssemblies |
Gets or sets the assemblies to which the current attribute apply.
(Inherited from MulticastAttribute.) | |
| AttributeTargetElements |
Gets or sets the kind of elements to which this custom attributes applies.
(Inherited from MulticastAttribute.) | |
| AttributeTargetExternalMemberAttributes |
Gets or sets the visibilities, scopes, virtualities, and implementation
of members to which this attribute applies, when the member is external to the current module.
(Inherited from MulticastAttribute.) | |
| AttributeTargetExternalTypeAttributes |
Gets or sets the visibilities of types to which this attribute applies,
when this type is external to the current module.
(Inherited from MulticastAttribute.) | |
| AttributeTargetMemberAttributes |
Gets or sets the visibilities, scopes, virtualities, and other characteristics
of members to which this attribute applies.
(Inherited from MulticastAttribute.) | |
| AttributeTargetMembers |
Gets or sets the expression specifying to which members
this instance applies.
(Inherited from MulticastAttribute.) | |
| AttributeTargetParameterAttributes |
Gets or sets the passing style (by value, out or ref)
of parameters to which this attribute applies.
(Inherited from MulticastAttribute.) | |
| AttributeTargetParameters |
Gets or sets the expression specifying to which parameters
this instance applies.
(Inherited from MulticastAttribute.) | |
| AttributeTargetTypeAttributes |
Gets or sets the attributes of types to which this attribute applies. Visibility, scope (Instance or Static)
and generation are the only categories that are taken into account; attributes of other categories are ignored.
(Inherited from MulticastAttribute.) | |
| AttributeTargetTypes |
Gets or sets the expression specifying to which types
this instance applies.
(Inherited from MulticastAttribute.) | |
| Instance |
Gets the object to which the current aspect has been applied.
(Inherited from InstanceLevelAspect.) | |
| RuntimeVerificationEnabled |
Determines whether the code should be verified against the model at runtime.
The default value is true for the debug build configuration and false for the release build configuration.
(Inherited from ThreadAwareAttribute.) | |
| UnsupportedTargetAction |
Specifies the action to take when the aspect is applied to an unsupported target element. This property affects only simple aspects, not composite aspects.
(Inherited from Aspect.) |
| Name | Description | |
|---|---|---|
| CompileTimeInitialize |
Method invoked at build time to initialize the instance fields of the current aspect. This method is invoked
before any other build-time method.
(Inherited from AggregatableClientAttribute.) | |
| CompileTimeValidate(Object) |
Method invoked at build time to ensure that the aspect has been applied to the right target.
(Inherited from TypeLevelAspect.) | |
| CompileTimeValidate(Type) |
Method invoked at build time to ensure that the aspect has been applied to the right target.
(Inherited from ThreadAwareAttribute.) | |
| CreateInstance |
Creates a new instance of the aspect based on the current instance, serving as a prototype.
(Inherited from InstanceLevelAspect.) | |
| Finalize |
Destructor.
(Inherited from ThreadAwareAttribute.) | |
| GetAspectConfiguration |
Method invoked at build tome to get the imperative configuration of the current Aspect.
(Inherited from Aspect.) | |
| OnCloned |
Method called after the an object enhanced by the current aspect has been
cloned using MemberwiseClone(). The this
parameter refers to the new aspect instance in the cloned object.
(Overrides InstanceLevelAspect.OnCloned(ICloneAwareAspect).) | |
| OnInstanceConstructed |
Executed when the target instance gets fully initialized, i.e. just after all constructors have completed.
(Inherited from AggregatableClientAttribute.) | |
| OnSerializing |
Requires read access level to the current object before serialization can proceed.
This method will be introduced into the target class.
(Inherited from ThreadAwareAttribute.) | |
| RuntimeInitializeInstance |
Initializes the aspect instance. This method is invoked when all system elements of the aspect (like member imports)
have completed.
(Inherited from ReadOnlyThreadAwareAttribute.) | |
| ToString | Returns a string that represents the current object. (Overrides Object.ToString().) |
| Name | Description | |
|---|---|---|
| AcquireAccess(ObjectAccessLevel) | Overloaded.
Acquires access to given object and returns the ConcurrentAccessToken.
(Defined by ThreadAwareExtensions.) | |
| AcquireAccess(ObjectAccessLevel, ConcurrentAccessToken) | Overloaded.
Acquires access for a given object and gets the ConcurrentAccessToken as a reference parameter.
(Defined by ThreadAwareExtensions.) | |
| AcquireAccessAsync |
Asynchronously acquires access for a given object.
(Defined by ThreadAwareExtensions.) |
Accessing a freezable object from a different thread than the one that created before the Freeze() method has been invoked it will result in a ThreadMismatchException.
Attempts to modify a freezable object after the Freeze() method has been invoked will result in an ObjectReadOnlyException.
