  extended by codesimian.CS
      extended by codesimian.DefaultCS
          extended by codesimian.Neg
All Implemented Interfaces:
CodeSimian, java.io.Serializable

public class Neg
extends DefaultCS

If countP() == 1, returns -param0.
If countP() > 1, returns param0 - param1 - param2 - param3...
Adds param0 and subtracts the rest.
-(8) equals -8
-(8 0) equals 8
-(8 3) equals 5
-(8 3 1) equals 4

Method Summary
 double DForProxy()
          D() and DForProxy() are the 2 most important functions in CS.
 java.lang.String javaCode(CS listOfCodeAlreadyTraversed)
          this function could use a better algorithm, but for now try to get javaCode(CS) to work at all.
 java.lang.String keyword()
          For the CodeSimian language as a String.
CodeSimian language keyword, like "+" "*" "max" ">" etc.

Override this function if you want to specify a keyword other than how I derive them from the class name, like + for Add.

Some CSs might never be intended to be used in the language by their keyword.
The best example (4/05) is Num, because it is used in the language like "3.4" instead of "num()".
 int maxP()
          Maximum quantity of Params
 int minP()
          For DForProxy().
Minimum number of parameters in param[] needed to call DForProxy().
Defines which indexs of param[] DForProxy() can use.
Functions with a different number of parameters must override this.
OVERRIDE THIS FUNCTION IF EXEC USES A DIFFERENT NUMBER OF PARAMETERS.
Default is 1.
 int parsePriority()
          Returns the parsing priority of this CS type, in some language syntax, probably CodeSimian's.

Constructor Detail

Neg

public Neg()
Method Detail

keyword

public java.lang.String keyword()
Description copied from class: DefaultCS
For the CodeSimian language as a String.
CodeSimian language keyword, like "+" "*" "max" ">" etc.

Override this function if you want to specify a keyword other than how I derive them from the class name, like + for Add.

Some CSs might never be intended to be used in the language by their keyword.
The best example (4/05) is Num, because it is used in the language like "3.4" instead of "num()".
Default: Returns class name, minus package name (and its dots), and change the first letter to lowercase.

For example, CS.MaxParams does not override keyword(), which returns "maxP".

Overrides:
keyword in class DefaultCS
See Also:
CS.parent(), CS.newInstance(), CS.name()

parsePriority

public int parsePriority()
Description copied from class: CS
Returns the parsing priority of this CS type, in some language syntax, probably CodeSimian's. Default parsePriority is 0. Default CodeSimian parsePriorities use +100 or -100 increments, to allow many priorities to be inserted in the middle.

This will later be useful for infix syntax. Instead of: +(/(1 2) *(3 4 5)) you type: 1/2+3*4*5

Returns 0 by default.

Overrides:
parsePriority in class CS

DForProxy

public double DForProxy()
Description copied from class: CS
D() and DForProxy() are the 2 most important functions in CS. They execute this CS. All other execute functions, by default, use DForProxy instead of reinventing-the-wheel for their own type.

For example, J() calls JForProxy() which calls DForProxy(). D() calls DForProxy() directly.

Execute this CS and cast to double. D() is the main EXECUTE function. D() uses DForProxy(). DForProxy() is the main action of every CS, the most important function. By default, all other primitive EXECUTE functions defer to D.
Functions that EXECUTE this CS: L(Class) L(int,Class,int) Z() B() C() S() I() J() F() D() V()

Specified by:
DForProxy in class DefaultCS

minP

public int minP()
Description copied from class: DefaultCS
For DForProxy().
Minimum number of parameters in param[] needed to call DForProxy().
Defines which indexs of param[] DForProxy() can use.
Functions with a different number of parameters must override this.
OVERRIDE THIS FUNCTION IF EXEC USES A DIFFERENT NUMBER OF PARAMETERS.
Default is 1.

Overrides:
minP in class DefaultCS

maxP

public int maxP()
Description copied from class: CS
Maximum quantity of Params

Overrides:
maxP in class CS

javaCode

public java.lang.String javaCode(CS listOfCodeAlreadyTraversed)
this function could use a better algorithm, but for now try to get javaCode(CS) to work at all.

Overrides:
javaCode in class DefaultCS
Returns:
String of Java code, or null if this CS does not know how to convert itself to Java code.
