When overridden in a derived class, gets an object that supports the requested pattern, based on PatternInterface input and the peer's implementation of known patterns.
Assembly: System.Windows (in System.Windows.dll)
Public MustOverride Function GetPattern ( _ patternInterface As PatternInterface _ ) As Object
public abstract Object GetPattern( PatternInterface patternInterface )
A value from the PatternInterface enumeration.
The object that implements the pattern interface; nullNothingnullptra null reference (Nothing in Visual Basic) if this peer does not support this interface.
Notes to Inheritors
The initial implementation is empty. This method does not have a "Core" parallel method, you override GetPattern itself.
You are expected to return existing values from the PatternInterface enumeration, which correspond to pattern definitions in System.Windows.Automation.Provider. In cases where no existing pattern or provider interface matches, use null. Often this also suggests that GetAutomationControlType should return Custom.
