  codesimian.CS<CSGeneric>
      codesimian.DefaultCS
          codesimian.Subtract

All Implemented Interfaces:

CodeSimian

public class Subtract
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() Execute this CS and cast to double.
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.
java.lang.String	toJavaCode(CSCallOptions options, JavaCodeWritingState state) returns the code for a new subclass of CS that does the same thing as this network of code.

Subtract

public Subtract()

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

Execute this CS and cast to double.

D() and DForProxy() are the 2 most important functions in CS. They execute this CS. All other execute functions, by default, return DForProxy cast to their own type.

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

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

toJavaCode

public java.lang.String toJavaCode(CSCallOptions options,
                                   JavaCodeWritingState state)

Description copied from class: CS

returns the code for a new subclass of CS that does the same thing as this network of code. Parts of the network that cant be converted to java code become the parameters of this new type of CS.

Must return an atomic string of Java code. For example "(3+PD(4)*5)" or "3" or "Math.sin(3.45)" are ok but "3+(PD(4)*5)" and "3+4*5" are not. For example, if 2 of these return a primitive (but not boolean), then I should be able to put "+" between them and it be valid Java code.

Possibly useful code: Reflect6.java has this design reflect6(return instance getSetInsertOrDelete location size value)

Overrides:

toJavaCode in class CS
