Parameters

• time
  Type: System.Int64

  A time value that will be returned by the LastUpdated method. This value is not used internally.

• sourceVersion
  Type: System.Int64

• prepareOptions
  Type: Microsoft.Xaml.XamlPrepareOptions

  Options to prepare the context for one or more calls on the interface.

• offset
  Type: System.Int32

  An optional offset to use to help prepare for a call. Specifying -1 indicates that no offset is ready. Specifying a non-negative offset might cause more work to be done than necessary if the prepared call is not eventually made.

Return Value

Type: System.Int64
A value that represents the version of the source that any errors occurred in. This version is the last parsed version.

Remarks

The Update method must be called before any of the other methods will return a valid result.
