Method Documentation
| __init__ | ( | self ) |
Create an Error object, representing success, i.e. no error.
| __init__ | ( | self, | ||
| QString | message, | |||
| int | code=ErrorUnknown | |||
| ) |
Create an Error object.
- Parameters:
-
message A human-readable error message.
- Parameters:
-
code An optional machine-readable error code. Can be one of Soprano.ErrorCode or a user defined value which has to be bigger than ErrorUnknown. The redland backend for example uses error codes <i>ErrorUnknown + redlandCode</i>.
| __init__ | ( | self, | ||
| Soprano.Error.Error | a0 | |||
| ) |
Copy constructor
| __init__ | ( | self, | ||
| ErrorData | a0 | |||
| ) |
\cond protected_error_members
| int code | ( | self ) |
An error code. If the error code is #ErrorNone the Error instance represents success. The code can either be one of the values of ErrorCode or a value above #ErrorUnknown.
Example: The redland backend defines the error code as:
ErrorUnknown + librdf_log_message_code()
\sa ErrorCode
| bool isParserError | ( | self ) |
- Returns:
- true if this Error instance represents a parser error. In that case the error can be converted to a ParserError.
| QString message | ( | self ) |
A string explaining the error in detail. This string is not necessarily translated (this depends on the plugin implementation).
- Returns:
- An error message describing the error or an empty string for no-error (i.e. success) instances.
| bool operator bool | ( | self ) |
An %Error evalutes to a boolean, indicating if an %Error is "set".
- Returns:
- false if code() == #ErrorNone, true otherwise.
Thus, an Error object can easily be checked as follows:
model.addStatement( s );
if( model.lastError() ) {
displayError( model.lastError() );
}
| Soprano.Error.ParserError toParserError | ( | self ) |
Converts this error into a ParserError. This has the same effect as
Error e; ParserError p1( e );
- Returns:
- If isParserError() returns true a ParserError with a valid Locator value, otherwise a ParserError with an empty Locator.
