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.

Method Detail

getType

public static int getType(char[] ch,
                          int offset,
                          int length)

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.
