All Implemented Interfaces:

CodeSimian, java.io.Serializable

public class TextAreaCS
extends DefaultCS

A GUI TextArea wrapped in a CS. Exec() is only called externally. This is a STRING. Its params are the char values. Use P() to get the text, and setP and deleteP() to set the text. Exec() returns the string length.

This class should later be changed to use all the text if no text is selected or only the selected text if any text is selected. countP() will change depending on what you select.

int	indexP(CS myParam) TextAreaCS's only params are from Const.pool().
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() returns the next char in the string.
CS	P(int charIndex) Returns a Const from the constant-pool whose value equals the char with index 'charIndex' in the string. Returns null if charIndex is invalid therefore causes: IndexOutOfBoundsException.
boolean	setObject(java.lang.Object setTo) false
boolean	setP(int index, CS setTo) sets one of the char values of the String displayed in this TextArea, one of my params
boolean	unknownCost() true, because it costs a lot to run the GUI, and a person might use it a lot.

Method Detail

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()

returns the next char in the string. If all have been returned by exec, starts again at index 0. public double DForProxy(){ if (countP() <= ++execPosition) execPosition = 0; //updateStringSkel(); //did the JTextArea change (human typed) ? return (double) text.getText().charAt(execPosition); }

Overrides:

minP in class DefaultCS

maxP

public int maxP()

Description copied from class: CS

Maximum quantity of Params

Overrides:

maxP in class CS

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()

description

public java.lang.String description()

Description copied from class: CS

a short description of this CS, shorter than the javadoc, but long enough to tell what the params are for. Example use: in automatically generated webpages for CodeSimian. Example: "returns sum of all params" for Add.

Overrides:

description in class DefaultCS

allParamsExistBeforeObserved

public boolean allParamsExistBeforeObserved()

cost

public double cost()

Description copied from class: CS

cost() should be changed to return a float, and should be renamed to costToExecute()

cost of EXECUTING this CS, not including any CSs it executes recursively. The INTERNAL cost.

One unit of myFuel() costs cost() units of fuel(). Beware of CSs that counterfeit fuel.

Returns 1 by default.

Overrides:

cost in class CS

unknownCost

public boolean unknownCost()

true, because it costs a lot to run the GUI, and a person might use it a lot. Somebody could copy/paste a huge text into this window.

getObject

public java.lang.Object getObject()

Description copied from class: CS

Returns the main Object that this CS wraps. This function is deprecated and should be replaced with L(Object.class), which uses getObject(). Then getObject() should be completely removed. L(Class) is more flexible.

Overrides:

getObject in class DefaultCS

See Also:

anyObject

setObject

public boolean setObject(java.lang.Object setTo)

false

Overrides:

setObject in class DefaultCS

See Also:

anyObject

setP

public boolean setP(int index,
                    CS setTo)

sets one of the char values of the String displayed in this TextArea, one of my params

Overrides:

setP in class DefaultCS

P

public CS P(int charIndex)

Returns a Const from the constant-pool whose value equals the char with index 'charIndex' in the string.
Returns null if charIndex is invalid therefore causes: IndexOutOfBoundsException.

Overrides:

P in class DefaultCS

Parameters:

charIndex - range 0 to countP()-1 inclusive

See Also:

CS.heap()

countP

public int countP()

returns string length

Overrides:

countP in class DefaultCS

deleteP

public boolean deleteP(int index)

deletes a char from the string and returns a Const from the constant-pool with its value * public CS deleteP(int index){ if (index < 0 || countP() <= index){ String t = text.getText(); text.setText( t.substring(0, index) + t.substring(index+1, t.length()) ); if (index < execPosition) execPosition--; return Const.pool( (double) t.charAt(index) ); } return null; }

Overrides:

deleteP in class DefaultCS

indexP

public int indexP(CS myParam)

TextAreaCS's only params are from Const.pool(). Returns the index of the last param that equals myParam and is from the constant-pool, else returns -1.

This function is not much useful because theres only approximately 60 useful chars, and many will be repeated in the same string.

Overrides:

indexP in class DefaultCS
