void checkInvariant ( bool  doRecurse = true ) Check whether ImageFile class invariant is true. Parameters: [in] doRecurse If true, also check invariants of all children or sub-objects recursively. This function checks at least the assertions in the documented class invariant description (see class reference page for this object). Other internal invariants that are implementation-dependent may also be checked. If any invariant clause is violated, an E57Exception with errorCode of E57_ERROR_INVARIANCE_VIOLATION is thrown. Checking the invariant recursively may be expensive if the tree is large, so should be used judiciously, in debug versions of the application. Postcondition: No visible state is modified. Exceptions: E57_ERROR_INVARIANCE_VIOLATION or any other E57 ErrorCode See also: CheckInvariant.cpp example, Node::checkInvariant
