Method Details

evaluate

public void evaluate(TargetApplications target)

Description copied from class: TargetApplicationsNamespace

Evaluate the namespace against given target applications if it is necessary. Only self/not-self/app-label namespace types require this evaluation step, because they are not binding to a specific scope during initiating. So we do lazy binding for them in this method.

Specified by:

evaluate in interface Evaluable<TargetApplications>

Overrides:

evaluate in class TargetApplicationsNamespace

Parameters:

target - a generic type target that impacts this evaluation.

toString

public String toString()

Overrides:

toString in class TargetApplicationsNamespace
