Method Summary

void	close(java.lang.String databaseName, java.lang.String tableName, AbleSecureKey key) Closes all connections, both the AbleDBImport and AbleDBExport beans for this database table.

Method Detail

createTableConnection

public void createTableConnection(java.lang.String databaseName,
                                  java.lang.String tableName,
                                  java.lang.String schemaName,
                                  java.lang.String[] columnNames,
                                  java.lang.String[] columnTypes,
                                  AbleSecureKey key,
                                  boolean writeOnly)
                           throws java.rmi.RemoteException,
                                  PlatformPersistenceException

This creates an AbleDBExport and optionally an AbleDBImport bean and the table these beans will be dealing with if the table does not already exist. The Export bean will be used in the future to alter the table in any way, and the Import bean will be used to read info from the table.

Parameters:

databaseName - The name of the Database that the table will exist in.

tableName - The name of the table.

schemaName - The schema for this table.

columnNames - String[] containing the name of each column for this table.

columnTypes - String[] containing the type of each column for this table.

key - AbleSecureKey used to secure communication.

writeOnly - When true, the service is output only.

Throws:

AbleException - On all errors creating and initializing the AbleDBExport or AbleDBImport beans.

PlatformPersistenceException -

If unable to verify the key when the platform is secure.

If databaseName is null.

If tableName is null.

If columnNames is null.

If columnTypes is null.

If columnTypes and columnNames are of different lengths.

On errors creating the table.

java.rmi.RemoteException - On all remote errors.

insert

public void insert(java.lang.String databaseName,
                   java.lang.String tableName,
                   java.io.Serializable[] insertData,
                   AbleSecureKey key)
            throws java.rmi.RemoteException,
                   PlatformPersistenceException

Insert a record into a table.

Parameters:

databaseName - The name of the Database that the table will exist in.

tableName - The name of the table to insert into.

insertData - Serializable[] containing the data that is to be inserted into the table.

key - AbleSecureKey used to secure communication.

Throws:

PlatformPersistenceException -

If the insertData is null.

If unable to verify the key when the platform is secure.

If secure and the caller is not the one who originally set up the connection to this table.

If the table connection does not exist.

java.rmi.RemoteException - On all remote errors.

update

public void update(java.lang.String databaseName,
                   java.lang.String tableName,
                   java.util.Map updateMap,
                   java.util.Map whereMap,
                   AbleSecureKey key)
            throws java.rmi.RemoteException,
                   PlatformPersistenceException

Updates a row in a table.

Parameters:

databaseName - The name of the Database that the table will exist in.

tableName - The name of the table.

updateMap - This is the new data for the record that is to be updated. In this map the keys are the column names and the values are the column values. The columns that are not changing do not have to be present.

whereMap - This determines the where clause for the update statement. This Map will be used to build the where clause. The keys will be the column names, and the values will be the Object to match to for their respective column. If left null, or empty, everything will be deleted.

key - AbleSecureKey used to secure communication

Throws:

PlatformPersistenceException -

If the updateMap is null.

If unable to verify the key when the platform is secure.

If secure and the caller is not the one who originally set up the connection to this table.
