Element Details

sourceVariableName

String sourceVariableName

Deprecated, for removal: This API element is subject to removal in a future version.

The source planning variable is a chained planning variable that leads to the anchor.

Both the genuine variable and the shadow variable should be consistent: if A chains to B, then A must have the same anchor as B (unless B is the anchor).

When the Solver changes a genuine variable, it adjusts the shadow variable accordingly. In practice, the Solver ignores shadow variables (except for consistency housekeeping).

Returns:

the variable property name on this entity class that leads to the anchor
