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

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 9, AIR 1.0, Flash Lite 4

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.
