```
- Method Detail
  - getUndefinedDataType
```
public static DataType getUndefinedDataType(int size)
```
    Get an Undefined data-type instance of the requested size
    
    Parameters:
    
    size - data type size, sizes greater than 8 will cause an Undefined1[size] (i.e., Array) to be returned.
    
    Returns:
    
    Undefined data type
  - getUndefinedDataTypes
```
public static Undefined[] getUndefinedDataTypes()
```
  - isUndefined
```
public static boolean isUndefined(DataType dataType)
```
    Determine if the specified dataType is either a DefaultDataType, an Undefined data-type, or an Array of Undefined data-types.
    
    Parameters:
    
    dataType -
    
    Returns:
    
    true if dataType represents an undefined data-type in its various forms, else false.
  - isUndefinedArray
```
public static boolean isUndefinedArray(DataType dataType)
```
    Determine if the specified dataType is an undefined array used to represent large undefined data.
    
    Parameters:
    
    dataType -
    
    Returns:
    
    true if the specified dataType is an undefined array used to represent large undefined data, otherwise false.
