JsonParseError class

JsonParseError exceptions are typically thrown by the Parse function in the Json class and by the equivalent Unicode class JsonParse function when there is an error parsing JSON data.

To create a JsonParseError exception yourself, you typically use a SOUL Throw statement with a JsonParseError 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 a JsonParseError exception:

throw %(JsonParseError):new(characterPosition=%pos)

Remember that you catch an exception with the Catch statement. If an exception condition occurs outside a Catch for it, the request is canceled.

The JsonParseError class, like the Json class is available as of Model 204 7.6.

The JsonParseError methods

The following are the available JsonParseError class methods.

Method	Description
CharacterPosition	Position of character at which error was detected
Description	Description of the error
New	Create a new JsonParseError object

The methods in the class are described in the subsections that follow. In addition:

• Notation conventions for methods has information about the conventions followed.
• JsonParseError methods syntax is a single page that contains the syntax diagrams of all the methods in the class.

CharacterPosition property

Position of character at which error was detected (JsonParseError class)

This ReadOnly property returns a number that indicates the character position (unicode characters are each two bytes long) in the unicode string being parsed where the error was detected.

Syntax

%number = jsonParseError:CharacterPosition

Syntax terms

%number	The character position in the input Unicode string where the parse error was detected.
jsonParseError	A reference to an instance of a JsonParseError object.

Description property

Description of the error (JsonParseError class)

This ReadOnly property returns a string that describes the error that was encountered while parsing the JSON data.

Syntax

%string = jsonParseError:Description

Syntax terms

%string	Text the describes the error that was encountered while parsing JSON data.
jsonParseError	A reference to an instance of a JsonParseError object.

New constructor

Create a new JsonParseError object (JsonParseError class)

This Constructor generates an instance of a JsonParseError exception.

Syntax

%jsonParseError = [%(JsonParseError):]New( CharacterPosition= number, - Description= string)

Syntax terms

%jsonParseError	A reference to an instance of a JsonParseError object.
[%(JsonParseError):]	The class name in parentheses denotes a Constructor.
number	The character position in the input unicode string where the parse error was detected.
string	Text that describes the error. It must be 127 characters long or less.
