Detailed Description

Error Class.

Library: dataccess

The IliErrorList is a subclass of the IliErrorSink class that keeps a record of all the error messages it catches. Member functions are provided to browse through the recorded error messages or alter them.

IliErrorMessage, IliErrorReporter, IliErrorSink.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class defines the following accessors:

Data accessors

Name Type Equivalent methods
errorsCount Int getErrorsCount()

Method accessors

Name Return type Equivalent methods
addError(IliErrorMessage msg) Void addError(msg)
appendErrorList(IliErrorList list) Void append(list)
getErrorAt(Int index) IliErrorMessage getErrorAt(index)
removeAllErrors() Void removeAllErrors()
report(IlvAbstractView view) Void defaultErrorReporter.reportErrors(view)

Here is an example of using an IliErrorList object :

var list = new IliErrorList();
var ds = Application.EMP_PNL.EMP_DS;
var i;
ds.addErrorSink(list);
// do some interesting work with ds
// ...
ds.removeErrorSink(list);
for (i = 0; i < list.errorsCount; ++i) {
writeln(list.getErrorAt(i).prettyMessage);
}
