X, Y and PI variables are predefined and can be immediately used in the expression.

createFunc(String, IFunction) - Method in interface com.bestcode.mathparser.IMathParser

createFunc method creates a new function that takes n number of parameters in the parser's list of functions.

createVar(String, double) - Method in interface com.bestcode.mathparser.IMathParser

Same as setVariable(String, double);

D

deleteAllFuncs() - Method in interface com.bestcode.mathparser.IMathParser

DeleteAllFuncs method deletes all variables from the list of available functions.

deleteAllVars() - Method in interface com.bestcode.mathparser.IMathParser

DeleteAllVars method deletes all variables from the list of available variables.

deleteFunc(String) - Method in interface com.bestcode.mathparser.IMathParser

deleteFunc method deletes an existing function from the list of available functions.

deleteVar(String) - Method in interface com.bestcode.mathparser.IMathParser

deleteVar method deletes an existing variable from the list of available variables.

E

evaluate() - Method in interface com.bestcode.mathparser.IMathParser

Evaluates the expression and returns the result of it.

F

freeParseTree() - Method in interface com.bestcode.mathparser.IMathParser

FreeParseTree can be explicitly called to free the resources taken by the allocated Parse tree when an expression is parsed.

G

getExpression() - Method in interface com.bestcode.mathparser.IMathParser

Please see setExpression() method to read about Expression property.

getFunctions() - Method in interface com.bestcode.mathparser.IMathParser

Returns an array of functions declared for this parser.

getInvalidPortionOfExpression() - Method in class com.bestcode.mathparser.ParserException

Returns the expression string that cannot be parsed.

getLocale() - Method in interface com.bestcode.mathparser.IMathParser

Returns the locale of this parser instance.

getNumberOfParams() - Method in class com.bestcode.mathparser.TwoParamFunc

getNumberOfParams() - Method in class com.bestcode.mathparser.OneParamFunc

getNumberOfParams() - Method in interface com.bestcode.mathparser.IFunction

This method returns the length of the parameters array that will be passed to the run(IParameter[]) method.
For example, for a function like F(X, Y, Z), this function should return 3.

getOptimizationOn() - Method in interface com.bestcode.mathparser.IMathParser

Set OptimizationOn to let the bcParser component evaluate constant expressions at parse time.

getSubExpression() - Method in class com.bestcode.mathparser.ParserException

Returns the subexpression that is the immediate parent of the error portion.
For example, if the expression is 3+LN(MAX(4,)) then getInvalidPortionOfExpression() would return MAX(4,) and getSubExpression() would return LN(MAX(4,))

The returned sub expressions may not exactly match the original string supplied as the expression since space characters and paranthesis may be substituted for efficient parsing.

getValue() - Method in interface com.bestcode.mathparser.IParameter

getValue() - Method in interface com.bestcode.mathparser.IMathParser
