Properties

Property	Usage	Description
SubCondition	Required/Content property	The conditions to test on the left side of the invoked member owner.

Example

In this case we want to capture the left side of the expression being called. Here's an example of using this mapping action in conjuction with AssignName and WithLeftSideOfDottedAccess.

Notes

• This condition succeeds if its inner conditions succeed.
