Class MathExecutor
- package NXP
| Methods |
| public __clone() |
| public __construct() Base math operators |
| public addFunction(string $name, ?callable $function = NULL) : self Add function to executor
|
| public addOperator(NXP Add operator to executor |
| public clearCache() : self Clear token's cache |
| public execute(string $expression, bool $cache = true) Execute expression
|
| public getCache() : array Get cache array with tokens
|
| public getFunctions() : array Get all registered functions
|
| public getOperators() : array Get all registered operators to executor
|
| public getVar(string $variable) : ?mixed Get a specific var
|
| public getVars() : array Get all vars
|
| public removeOperator(string $operator) : self Remove a specific operator |
| public removeVar(string $variable) : self Remove variable from executor |
| public removeVars() : self Remove all variables and the variable not found handler |
| public setDivisionByZeroIsZero() : self Set division by zero returns zero instead of throwing DivisionByZeroException |
| public setVar(string $variable, ?mixed $value) : self Add variable to executor. To set a custom validator use setVarValidationHandler.
|
| public setVarNotFoundHandler(callable $handler) : self Define a method that will be invoked when a variable is not found. The first parameter will be the variable name, and the returned value will be used as the variable value. |
| public setVars(array $variables, bool $clear = true) : self Add variables to executor
|
| public setVarValidationHandler(?callable $handler) : self Define a validation method that will be invoked when a variable is set using setVar. The first parameter will be the variable name, and the second will be the variable value.
