- Method Detail
  - getAutoInstanceNumber
```
int getAutoInstanceNumber()
```
    Instance holders may have specific rules for instance IDs for dynamically created instances (null InstanceSeg). The delegate uses the lowest open instance number. The caller should synchronize on the holder's public "children" field before calling this until after setting the child's segment.
    
    Returns:
  - getMaxInstance
```
int getMaxInstance()
```
  - getNumInstances
```
int getNumInstances()
```
  - getInstances
```
int[] getInstances()
```
  - getInstance
```
CipInstance getInstance(int inst)
```
