[SerializableAttribute] public abstract class MethodInterceptionAspect : MethodLevelAspect, IMethodInterceptionAspect, IMethodLevelAspect, IAspect, IAsyncMethodInterceptionAspect
The MethodInterceptionAspect type exposes the following members.
Name | Description | |
---|---|---|
MethodInterceptionAspect | Initializes a new instance of the MethodInterceptionAspect 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.) | |
SemanticallyAdvisedMethodKinds |
Determines which target methods will be advised semantically. This affects the behavior of the aspect when it's applied to
iterator or async methods, which are compiled into state machines.
| |
SerializerType |
Gets or sets the Type of the serializer (a type derived
from AspectSerializer) used to serialize the aspect instance
at build time and deserialize it at runtime.
(Inherited from Aspect.) | |
UnsupportedTargetAction |
Specifies the action to take when the aspect is applied to an async method with unsupported return value type.
|
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 MethodLevelAspect.) | |
CompileTimeValidate(Object) |
Method invoked at build time to ensure that the aspect has been applied to the right target.
(Inherited from MethodLevelAspect.) | |
CompileTimeValidate(MethodBase) |
Method invoked at build time to ensure that the aspect has been applied to the right target.
(Inherited from MethodLevelAspect.) | |
CreateAspectConfiguration |
Method invoked at build time to create a concrete AspectConfiguration instance specifically
for the current Aspect type.
(Overrides Aspect.CreateAspectConfiguration().) | |
GetAspectConfiguration |
Method invoked at build tome to get the imperative configuration of the current Aspect.
(Inherited from Aspect.) | |
OnInvoke |
Method invoked instead of the method to which the aspect has been applied.
| |
OnInvokeAsync |
Method invoked instead of the method to which the aspect has been applied.
| |
RuntimeInitialize |
Initializes the current aspect.
(Inherited from MethodLevelAspect.) | |
SetAspectConfiguration(AspectConfiguration, MethodBase) |
Method invoked at build time to set up an AspectConfiguration object according to the current
Aspect instance and a specified target element of the current aspect.
(Overrides MethodLevelAspect.SetAspectConfiguration(AspectConfiguration, MethodBase).) | |
SetAspectConfiguration(AspectConfiguration, Object) |
Method invoked at build time to set up an AspectConfiguration object according to the current
Aspect instance and a specified target element of the current aspect.
(Inherited from MethodLevelAspect.) |
Applying a MethodInterceptionAspect to a method results in the body of this method to be replaced by a call to the aspect OnInvoke(MethodInterceptionArgs) method of the current class. The original method body is moved into a new method, which can be called by the aspect by invoking the Proceed() method, or by using the object Binding.
PostSharp creates a local copy of all by-reference parameters (in, out, ref) and this local copy is passed to the intercepted method, not the original argument. This may have unwanted effects on multi-threaded code (because the argument value is not changed at the same moment as before) or when applying the aspect on a P-Invoke method (because a by-reference parameter could represent the starting address of a larger buffer). |
All classes implementing IAspect should typically be marked as serializable using the SerializableAttribute or PSerializableAttribute custom attribute . Fields that are only used at runtime (and unknown at compile-time) should be carefully marked with the NonSerializedAttribute or PNonSerializedAttribute custom attribute. When PostSharp is used on a platform that does not support aspect serialization (such as .NET Compact Framework, Silverlight, or Windows Phone), or when another aspect serializer is used, it is not necessary to mark the aspect class as serializable.
