MethodMappingWriter.EmitStoreContextItemIntoLocalConditional Method (MethodMappingContextItem, ILocalStorage, ITypeSignature, InstructionWriter, Action<InstructionWriter, ILocalStorage>, Action<InstructionWriter, ILocalStorage>)
Emits instructions that store the value of a context item to a local variable. If the item is not available in the current context, it is loaded using instructions emitted by a delegate.

Parameters

methodMappingContextItem
Type: PostSharp.Sdk.AspectInfrastructure.MethodMappingContextItem
The context item.
contextItemLocal
Type: PostSharp.Sdk.AspectInfrastructure.ILocalStorage
The local variable where the value of the context item should be stored. If the input value of this parameter is null, a local variable of type contextItemType is created.
contextItemType
Type: PostSharp.Sdk.CodeModel.ITypeSignature
The type of the context item, used to create the local variable if contextItemLocal is null.
instructionWriter
Type: PostSharp.Sdk.CodeModel.InstructionWriter
An InstructionWriter.
loadContextItemAction
Type: System.Action<InstructionWriter, ILocalStorage>
A delegate that emits instructions that load the context item value on the stack. This delegate is invoked in case the item is not available in the current context.
emitIfLoadedFromContextAction
Type: System.Action<InstructionWriter, ILocalStorage>
A delegate that emits instructions executed in case the item has been loaded from context, or null if nothing should be executed if the item is loaded from context.
