- Method Detail
  - parseNames
```
public static String[] parseNames(String names)
```
    Parses op names contained in specified String according to the following format:
    'prefix1'.'prefix2' , 'prefix1'.'prefix3'
    E.g. "math.add, math.pow".
    The name delimiter is a comma (,). Furthermore, names without prefixes are added. The above example will result in the following output:
    
    [math.add, add, math.pow, pow]
    Parameters:
    
    names - the string containing the names to parse
    
    Returns:
    
    an array of parsed Op names
  - validate
```
public static void validate(OpInfo info)
```
    Asserts common requirements for an OpInfo to be valid
    
    Parameters:
    
    info - the OpInfo to validate
  - IOIndex
```
public static int IOIndex(OpInfo info)
```
    Returns the index of the argument that is both the input and the output. If there is no such argument (i.e. the Op produces a pure output), -1 is returned
    
    Returns:
    
    the index of the mutable argument.
  - hasPureOutput
```
public static boolean hasPureOutput(OpInfo info)
```
  - dependencies
```
public static List<OpDependencyMember<?>> dependencies(OpInfo info)
```
    Gets the op's dependencies on other ops.
  - describe
```
public static String describe(OpInfo info)
```
    Forms a verbose description of info
    
    Parameters:
    
    info - an OpInfo
    
    Returns:
    
    a verbose description of info
