Extension Methods| Name | Description | |
|---|---|---|
 | AddOrUpdateData |
Adds or updates data on the context
(Defined by DataContextExtensions) |
| ContainsStackEntry |
Returns true if the data stack contains an entry
(Defined by DataContextExtensions) |
| ConvertTReturn |
The purpose of this method is to convert object me to TReturn. Why?
Because if you have an instance of Act that actually needs to be a SubstanceAdministration we can't just cast
so we have to copy.
(Defined by ExtensionMethods) |
| CreateInformationModelGuard |
Should be called when converting to information model to prevent stack overflows
(Defined by DataContextExtensions) |
| EstablishProvenance |
Establish a provenance entry for the specified connection
(Defined by DataContextExtensions) |
| GetProvenance |
Get provenance from the context
(Defined by DataContextExtensions) |
| Install |
Install the specified object
(Defined by SqlFeatureUtil) |
| IsInstalled |
Returns true if the migration has been installed
(Defined by SqlFeatureUtil) |
| IsLoadingInformationModel |
Determine if the information model is loading
(Defined by DataContextExtensions) |
| PeekData |
Set data on the context in a safe manner

| PopData |
Set data on the context in a safe manner
(Defined by DataContextExtensions) |
| PushData |
Set data on the context in a safe manner
(Defined by DataContextExtensions) |
| ShouldDisableObjectValidation |
Should disable object validation
