MultiVariantObject (powsybl 4.1.1 API)

All Known Implementing Classes:

AbstractMultiVariantConnectableExtension, AbstractMultiVariantIdentifiableExtension, BatteryImpl, LoadDetailImpl, SlackTerminalImpl
```
public interface MultiVariantObject
```
An interface implemented by network objects that have attributes depending on the variant.
A class implementing this interface internally manages an array of variants and is notified when the array need to be resized thanks to extendVariantArraySize and reduceVariantArraySize callbacks.

- Method Detail
  - extendVariantArraySize
```
void extendVariantArraySize(int initVariantArraySize,
                            int number,
                            int sourceIndex)
```
    Called to extend the variant array.
    
    Parameters:
    
    initVariantArraySize - initial variant array size
    
    number - number of element to add
    
    sourceIndex - the variant index to use to initialize new variants
  - reduceVariantArraySize
```
void reduceVariantArraySize(int number)
```
    Called to reduce the variant array.
    
    Parameters:
    
    number - number of element to remove
  - deleteVariantArrayElement
```
void deleteVariantArrayElement(int index)
```
    Called to delete a variant array element.
    
    Parameters:
    
    index - the index of the variant array to delete
  - allocateVariantArrayElement
```
void allocateVariantArrayElement(int[] indexes,
                                 int sourceIndex)
```
    Called to allocate a variant array element. All new variants will be initialize using values of the variant sourceIndex.
    
    Parameters:
    
    indexes - the indexes of the variant array to allocate
    
    sourceIndex - the variant index to use to initialize new variants
