Method Detail

isResolvable

boolean isResolvable()

A persisted variable can not be guaranteed to be present. This method can be used to determine, if the variable is present.

The persisted variable will not be present, if the end user loads a different installation which does not contain the variable, or if the variable is deleted by the end user.

A program node storing a PersistedVariable instance in its Data Model will be undefined if the variable cannot be resolved (i.e. the variable is not present).

Returns:

true if this persisted variable is present in the PolyScope installation, otherwise false.
