 edu.hws.jcm.data.StandardFunction
| StandardFunction | | public class StandardFunction implements MathObject(Code) | | 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.
|
| Constructor Summary | |
| 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. | | public | StandardFunction(String name, int opCode)
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. |
| Method Summary | |
| public String | getName()
Return the name of this StandardFunction oject. | | public int | getOpCode()
Return the operation code for this standard function. | | public void | setName(String name)
Change the name of this StandardFunction. | | public static String | standardFunctionName(int opCode)
Return the usual name for the standard function with the
specified opCode. |
| StandardFunction | | public StandardFunction(int opCode)(Code) | | 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 | | public StandardFunction(String name, int opCode)(Code) | | 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.
|
| getName | | public String getName()(Code) | | Return the name of this StandardFunction oject.
|
| getOpCode | | public int getOpCode()(Code) | | Return the operation code for this standard function.
|
| setName | | public void setName(String name)(Code) | | Change the name of this StandardFunction. This shouldn't be done
if this object is registered with a Parser.
|
| standardFunctionName | | public static String standardFunctionName(int opCode)(Code) | | 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.
