public class OperatorNames
extends java.lang.Object
```
OperatorsNames purpose is to define all operators in the PostScript type 4 function definitions. The function also provides an accelerated operand lookup method #getType() which returns an integer representation of the operand so that it can be quickly compared/processed at a later time.

    Gets the operator type specified by the input substring. PostScript operands should all be lower case but this function will handle upper and mixed case if encountered.
    
    Parameters:
    
    ch - character array containing postscript calculator function.
    
    offset - starting offset of input substring.
    
    length - length of input substring.
    
    Returns:
    
    integer representing the operand found as described in class constants.
