Method Details

isAssigned

boolean isAssigned(Object element)

Parameters:

element - never null

Returns:

true if the element is contained in a list variable of any entity.

getLocationInList

ElementLocation getLocationInList(Object value)

Parameters:

value - never null

Returns:

never null

getUnassignedCount

int getUnassignedCount()

Consider colling this before isAssigned(Object) to eliminate some map accesses. If unassigned count is 0, isAssigned(Object) is guaranteed to return true.

Returns:

number of elements for which isAssigned(Object) would return false.
