* If \a this has already been allocated, this method checks that \a this has only one component. If not an INTERP_KERNEL::Exception will be thrown.
* If \a this has not already been allocated, number of components is set to one.
* This method allows to reduce number of reallocations on invocation of DataArrayDouble::pushBackSilent and DataArrayDouble::pushBackValsSilent on \a this.
