The InvalidBase64Data exception class describes an exception associated with finding non-base64-encoded data where base64-encoded data was expected, usually when decoding base64-encoded data.
To produce an InvalidBase64Data exception yourself, you typically use a User Language Throw statement with an InvalidBase64Data New constructor. This statement must be issued from within a method, and it can only be caught by the code that calls the method. For example, the following statement throws an InvalidBase64Data exception with the position set to
The InvalidBase64Data methods
The following are the available InvalidBase64Data class methods.
|New||Create a new InvalidBase64Data object|
|Position||Input string position where non-base64 encoding character found|
The methods in the class are described in the subsections that follow. In addition:
- Notation conventions for methods has information about the conventions followed.
- InvalidBase64Data methods syntax is a single page that contains the syntax diagrams of all the methods in the class.
Create a new InvalidBase64Data object (InvalidBase64Data class)
This Constructor generates an instance of an InvalidBase64Data exception. As shown below, the required argument of the New method is a setting of the Position property.
%invalidBase64Data = [%(InvalidBase64Data):]New( Position= number)
|%invalidBase64Data||A reference to an instance of an InvalidBase64Data object.|
|[%(InvalidBase64Data):]||The class name in parentheses denotes a Constructor.|
|Position||This name required parameter: Position, specifies the numeric value (number) for the position to be assigned to the InvalidBase64Data exception object's Position property when a data error is encountered.|
Input string position where non-base64 encoding character found (InvalidBase64Data class)
This ReadOnly property returns the position in the (expected) base64-encoded string where a non-base64-encoding character was found.
%number = invalidBase64Data:Position
|%number||This numeric value is the position in the base64 string where a non-base64 character was found.|
|invalidBase64Data||A reference to an instance of an InvalidBase64Data object.|
