Method Detail

getDpbKey

public static java.lang.Integer getDpbKey(java.lang.String name)

Get integer value of the DPB key corresponding to the specified name.

Parameters:

name - name of the key.

Returns:

instance of Integer corresponding to the specified name or null if value is not known.

getDpbMap

public static java.util.Map<java.lang.String,java.lang.Integer> getDpbMap()

Get mapping between DPB names and their keys.

Returns:

instance of Map, where key is the name of DPB parameter, value is its DPB key.

parseDpbString

public static java.lang.Object parseDpbString(java.lang.String name,
                                              java.lang.Object value)

processTpbMapping

public static void processTpbMapping(GDS gds,
                                     FirebirdConnectionProperties connectionProperties,
                                     java.util.Properties info)
                              throws FBResourceException

This method extracts TPB mapping information from the connection parameters and adds it to the connectionProperties. Two formats are supported:

• info contains "tpb_mapping" parameter pointing to a resource bundle with mapping information;
• info contains separate mappings for each of following transaction isolation levels: "TRANSACTION_SERIALIZABLE", "TRANSACTION_REPEATABLE_READ" and "TRANSACTION_READ_COMMITTED".

Parameters:

gds - GDS object

connectionProperties - FirebirdConnectionProperties to set transaction state

info - connection parameters passed into a driver.

Throws:

FBResourceException - if specified mapping is incorrect.

getTpbParam

public static java.lang.Integer getTpbParam(java.lang.String name)

Get value of TPB parameter for the specified name. This method tries to match string representation of the TPB parameter with its value.

Parameters:

name - string representation of TPB parameter, can have "isc_tpb_" prefix.

Returns:

value corresponding to the specified parameter name or null if nothing was found.
