Description | Increases the capacity of this vector, if necessary, to ensure that it can hold at least the number of components specified by the minimum capacity argument. If the current capacity of this vector is less than minCapacity, then its capacity is increased by replacing its internal data array with a larger one. The size of the new data array will be the old size plus the capacity increment, unless the value of capacity increment is less than or equal to zero, in which case the new capacity will be twice the old capacity; but if this new size is still smaller than minCapacity, then the new capacity will be minCapacity. | ||
