- Method Detail
  - getMinOccurs
```
@Nullable
Integer getMinOccurs()
```
    Retrieve the required minimum occurrence of the target instance. If specified, this value must be less than or equal to the value of IModelInstance.getMaxOccurs() and greater than IModelInstance.getMinOccurs().
    
    Returns:
    
    a non-negative integer or null if not defined
  - getMaxOccurs
```
@Nullable
Integer getMaxOccurs()
```
    Retrieve the required maximum occurrence of the target instance. If specified, this value must be less than the value of IModelInstance.getMaxOccurs() and greater than or equal to IModelInstance.getMinOccurs().
    
    Returns:
    
    a non-negative integer or null if not defined
