AbstractUnaryOperator(String oper, int precedence, bool leftAssoc): Creates a new operator.

booleanOperator ↔ bool: Whether this operator is boolean or not.

eval(Decimal? v1, Decimal? v2) → Decimal: Implementation for this operator.
override
evalLazy(LazyNumber v1, LazyNumber? v2) → LazyNumber: Implementation for this operator.
override
evalUnary(Decimal? v1) → Decimal
getOper() → String: Gets the String that is used to denote the operator in the expression.
inherited
getPrecedence() → int: Gets the precedence value of this operator.
inherited
isBooleanOperator() → bool: Gets whether this operator evaluates to a boolean expression. Returns true if this operator evaluates to a boolean expression.
inherited
isLeftAssoc() → bool: Gets whether this operator is left associative (true) or if this operator is right associative (false).
inherited
isUnaryOperator() → bool: True if the number of operands for this operator is 1, false if it is 2.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
