TypeError (ActionScript 3.0)

Package	Top Level
Class	public dynamic class TypeError
Inheritance	TypeError Error Object

Language version:

ActionScript 3.0

Runtime version:

AIR 1.0

A TypeError exception is thrown when the actual type of an operand is different from the expected type.

In addition, this exception is thrown when:

An actual parameter to a function or method could not be coerced to the formal parameter type.
A value is assigned to a variable and cannot be coerced to the variable's type.
The right side of the is or instanceof operator is not a valid type.
The super keyword is used illegally.
A property lookup results in more than one binding, and is therefore ambiguous.
A method is invoked on an incompatible object. For example, a TypeError exception is thrown if a RegExp class method is "grafted" onto a generic object and then invoked.
