Method Detail

e2ObjArg

public IExpr e2ObjArg(IExpr o0,
                      IExpr o1)

Overrides:

e2ObjArg in class AbstractArg2

numericEval

public IExpr numericEval(IAST ast)

Description copied from class: AbstractFunctionEvaluator

Numeric evaluation of a function. ast.get(0) contains the head (i.e. the function symbol) of this abstract syntax tree (AST). ast.get(1) to ast.get(n) contains the first to n-th argument of the function.
If necessary use the methods from the Validate class to check the number or types of arguments in the evaluate method.

Specified by:

numericEval in interface IFunctionEvaluator

Overrides:

numericEval in class AbstractFunctionEvaluator

Parameters:

ast - the abstract syntax tree (AST) which should be evaluated

Returns:

the evaluated object or null, if evaluation isn't possible

setUp

public void setUp(ISymbol symbol)

Description copied from class: AbstractFunctionEvaluator

Evaluate built-in rules and define Attributes for a function.

Specified by:

setUp in interface IEvaluator

Overrides:

setUp in class AbstractFunctionEvaluator

Parameters:

symbol - the symbol which should be set up
