AstUniOp

public AstUniOp()

Method Detail

args

public java.lang.String[] args()

Description copied from class: AstPrimitive

List of argument names. The length of the returned array should be equal to `nargs() - 1` (unless `nargs()` returns -1, in which case this function may return {"..."} or something similar).

Specified by:

args in class AstPrimitive<T extends AstUniOp<T>>

nargs

public int nargs()

Description copied from class: AstPrimitive

Number of function's arguments + 1. Thus, a binary operator like '+' should be declared with 3 nargs: ["+", lhs, rhs]. For variable-argument functions this method should return -1.

Specified by:

nargs in class AstPrimitive<T extends AstUniOp<T>>

exec

public Val exec(Val... args)

Description copied from class: AstBuiltin

Most Ast* functions will want to override this method. The semantics is "call this function with the provided list of arguments".

Overrides:

exec in class AstBuiltin<T extends AstUniOp<T>>

op

public abstract double op(double d)
