Exception API

Most of the exceptions raised by any of the other modules will be an instance of the exceptions described in this module.

class tgdb.exception.ExceptionType(value)

The type of exception encountered.

exception tgdb.exception.TGAdminParseException(reason, cause: Exception = None, position: int = 0, token: str = None)

Error with parsing the input to the administrative client terminal.

property position

The position that the error occurred in.

exception tgdb.exception.TGAuthenticationException(reason, errorcode=None, cause=None)

Exception for when the server refuses to authenticate the user because of a bad password or username.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGBadMagic(reason, errorcode=None, cause=None)

This exception could occur if the server and client are not on the same version of the Protocol Data Unit or if the server or clients messages are corrupted.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGBadVerb(reason, errorcode=None, cause=None)

This could occur if the client or server send a wrong verb identifier over.

abstract property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGChannelDisconnectedException(reason, errorcode=None, cause=None)

Occurs when the client loses connection with the server.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGConnectionTimeoutException(reason, errorcode=None, cause=None)

Occurs if the connection lasts too long.

If you are running into this exception frequently, you might want to wrap your code around a while loop with reinitializing the connection object.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGException(reason, errorcode=None, cause=None)

TIBCO Graph Database specific exceptions.

classmethod buildException(reason, errorcode=None, cause=None)

Client code should never initialize any exceptions directly.

property cause

Represents the cause of this exception, if there was one.

For example, this might occur if a KeyError gets raised when it should not, so the Python API handles that exception and tells the user what is the likely reason.

property errorcode

Gets the exception’s error code.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGImpExpException(reason, errorcode=None, cause=None)

Occurs when an import/export related error occurs.

exception tgdb.exception.TGInvalidMessageLength(reason, errorcode=None, cause=None)

Message received ended before the API expected.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGProtocolNotSupported(reason, errorcode=None, cause=None)

The server’s protocol is incompatible with this API’s protocol.

Might want to update either the server or this API.

property exceptionType

Gets the type of the exception.

exception tgdb.exception.TGSecurityException(reason, errorcode=None, cause=None)

Occurs when a security related issue occurs.

Contact your IT or security team to get this worked out. If only working

exception tgdb.exception.TGTransactionAlreadyInProgressException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionException(reason, errorcode=None, cause=None)

Baseclass for more detailed transaction-related exceptions.

Designed to catch specific instances of transaction failure. For example, if you want to upsert an entity, you can first try to insert it, which if it is already there, will cause a TGTransactionUniqueConstraintViolation, which you can catch with an except statement specifying that exception.

exception tgdb.exception.TGTransactionGeneralErrorException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionInBadStateException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionMalFormedException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionOptimisticLockFailedException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionResourceExceededException(reason, errorcode=None, cause=None)

class tgdb.exception.TGTransactionResponse(value)

More thorough transaction response than just error or success.

exception tgdb.exception.TGTransactionUniqueConstraintViolationException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionUniqueIndexKeyAttributeNullError(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTransactionVerificationErrorException(reason, errorcode=None, cause=None)

exception tgdb.exception.TGTypeCoercionNotSupported(fromtype, totype, isarray=False)

Attempted to convert from one type to one that is incompatible.

Think trying to convert a number type to a single character.

If running into this issue, please make sure that the types are compatible (i.e. explicitly convert to the type you want it to convert to).

exception tgdb.exception.TGTypeNotSupported(reason, errorcode=None, cause=None)

That type is not supported yet.

exception tgdb.exception.TGVersionMismatchException(reason, errorcode=None, cause=None)

The version between the server and client is out of sync.
