Method Detail

readResponse

Response readResponse(WarningMessageCallback callback)
               throws java.sql.SQLException,
                      java.io.IOException

Reads the response from the server.

Parameters:

callback - Callback object for warnings, null for default callback

Returns:

Response read.

Throws:

java.sql.SQLException - For errors returned from the server, or when attempting to read

java.io.IOException - For errors reading the response from the connection.

releaseObject

void releaseObject(int operation,
                   int objectId)
            throws java.sql.SQLException

Release object.

Parameters:

operation - Operation

objectId - Id of the object to release

Throws:

java.sql.SQLException

readSqlResponse

SqlResponse readSqlResponse(WarningMessageCallback callback)
                     throws java.sql.SQLException,
                            java.io.IOException

Convenience method to read a Response to a SqlResponse

Parameters:

callback - Callback object for warnings, null for default callback

Returns:

SqlResponse

Throws:

java.sql.SQLException - For errors returned from the server, or when attempting to read.

java.io.IOException - For errors reading the response from the connection.

getBlrCalculator

BlrCalculator getBlrCalculator()

Returns:

The BlrCalculator instance for this database.

enqueueDeferredAction

void enqueueDeferredAction(DeferredAction deferredAction)

Enqueue a deferred action.

FbDatabase implementations that do not support deferred actions are allowed to throw an UnsupportedOperationException

Parameters:

deferredAction - Deferred action

consumePackets

void consumePackets(int numberOfResponses,
                    WarningMessageCallback warningCallback)

Consumes packets notifying for warnings, but ignoring exceptions thrown from the packet.

This method should only be used inside the implementation if either packets need to be ignored, or to ensure that there is no backlog of packets (eg when an exception occurs during processing of multiple package responses).

Parameters:

numberOfResponses - Number of responses to consume.

warningCallback - Callback for warnings
