Class StandardFunction

edu.hws.jcm.data.StandardFunction
- All Implemented Interfaces:
MathObject
,Serializable
This class exists to associate standard functions, such as sin and abs, with
their names. Note that the functions are actually implemented in the
ExprsssionProgram class, where they are only represented by numerical operation
codes. An object of type StandardFunction contains a name and the operation
code of the associated standard function. A static routine, standardFunctionName,
gives the name associated with each operation code.

StandardFunction
public StandardFunction(int opCode) Create a StandardFunction object to represent the standard function with the given operation code, where opCode is one of the codes for standard functions defined in class ExpressionProgram. The name is the one associated with the opCode by the static function standardFunctionName() in this class. An error will occur if opCode is not one of the valid standard function operation codes. -
StandardFunction
Create a StandardFunction object to represent the standard function with the given operation code, where opCode is one of the codes for stadard functions defined in class ExpressionProgram. Use the specified name for the standard function. This allows you to make alternative names, such as "log" instead of "log10". An error will occur if opCode is not one of the valid standard function operation codes.

standardFunctionName
Return the usual name for the standard function with the specified opCode. The opcodes are defined in the ExpressionProgram class. Will throw an IllegalArgumentException if the specified oPcode is not the opcode for any standard function.
