Exception Summary |
| InterpreterException |
ATException is the superclass of all exceptions thrown by the AmbientTalk interpreter.
|
| XArityMismatch |
XArityMismatch is thrown during function application when actual arguments are bound to formal parameters
and there are either too many or too few actual arguments supplied. |
| XClassNotFound |
Raised when a request to load a class via a JavaPackage failed. |
| XDuplicateSlot |
An XDuplicateSlot exception is raised when a field or a method is added to
an object that already contains a field or method with the same name. |
| XIllegalApplication |
XIllegalApplication is thrown when a natively implemented method is applied incorrectly.
|
| XIllegalArgument |
An XIllegalArgument exception is thrown when primitive operations on native types
get passed an illegal argument value. |
| XIllegalIndex |
An XIllegalIndex exception is thrown by the evaluator whenever an invalid
value is used as the index into a table (e.g. when defining, assigning or referencing it). |
| XIllegalOperation |
XIllegalOperation is thrown whenever an operation is requested that is a violation
of the expected semantics of the interpreter. |
| XIllegalParameter |
An XIllegalParameter exception is raised when the interpreter detects a faulty
formal parameter list of a function or method when it is invoked.
|
| XIllegalQuote |
An XIllegalQuote exception is raised whenever an unquote-splice unquotation is discovered in an AG node where
the resulting table cannot be spliced. |
| XIllegalSplice |
XIllegalSplice is thrown when an @ token was not encountered in one of its legal
positions namely when unquoting a table or in the argument-list of an application. |
| XIllegalUnquote |
An XIllegalUnquote exception is raised when an unquotation is
discovered in a non-quoted piece of source code. |
| XImportConflict |
An XImportConflict exception is raised when an import: native fails
because the importing object already defines one or more methods or
fields available in the imported object. |
| XIndexOutOfBounds |
An XIndexOutOfBounds exception is raised when an attempt is made to access or modify an AGTable beyond its capacity. |
| XIOProblem |
The class XIOProblem is mainly a wrapper class for Java IOExceptions. |
| XNotInstantiatable |
Raised whenever a wrapped Java class cannot be instantiated because:
- it has no publicly accessible constructors
- it is abstract |
| XParseError |
XParseError is thrown when illegal input is parsed by the AmbientTalk parser. |
| XReflectionFailure |
An instance of the class XReflectionFailure is thrown when something goes wrong
when dealing with mirror or mirage operations. |
| XSelectorNotFound |
XSelectorNotFound is thrown during lookup when a particular field cannot be
found. |
| XSymbiosisFailure |
An instance of this class is raised whenever a symbiotic method invocation fails due to overloading
which could not be resolved given the actual arguments. |
| XTypeMismatch |
XTypeMismatch instances are thrown when a value conversion failed. |
| XUnassignableField |
An XUnassignableField exception is raised whenever a variable assignment fails because the variable/field is immutable.
|
| XUndefinedField |
An XUndefinedField exception is raised whenever a variable reference lookup fails,
or a field assignment lookup fails. |
| XUserDefined |
Instances of the XUserDefined act as wrappers for ATObjects which are thrown at the
ambienttalk level using the raise: primitive. |
