- Method Detail
  - values
```
public static VirtualDataWindowLookupOp[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (VirtualDataWindowLookupOp c : VirtualDataWindowLookupOp.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static VirtualDataWindowLookupOp valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getOp
```
public String getOp()
```
    Returns the string-value of the operator.
    
    Returns:
    
    operator string value
  - fromOpString
```
public static VirtualDataWindowLookupOp fromOpString(String stringOp)
```
    Map the operator from a string-value.
    
    Parameters:
    
    stringOp - to map from
    
    Returns:
    
    operator
    
    Throws:
    
    IllegalArgumentException - if the string operator cannot be understood
