InvalidBase64Data class
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 2:
throw %(invalidBase64Data):new(position=2)
The InvalidBase64Data methods
The following are the available InvalidBase64Data class methods.
| Method | Description |
|---|---|
| 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.
New constructor
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.
Syntax
%invalidBase64Data = [%(InvalidBase64Data):]New( Position= number)
Syntax terms
| %invalidBase64Data | A reference to an instance of an InvalidBase64Data object. |
|---|---|
| %(InvalidBase64Data) | The class name in parentheses denotes a shared method. |
| 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. |
Position property
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.
Syntax
%number = invalidBase64Data:Position
Syntax terms
| %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. |
