Method Detail

getMapper

public FIDMapper getMapper(java.lang.String catalog,
                           java.lang.String schema,
                           java.lang.String tableName,
                           java.sql.Connection connection)
                    throws java.io.IOException

Gets the appropriate FIDMapper for the specified table.

Specified by:

getMapper in interface FIDMapperFactory

Overrides:

getMapper in class DefaultFIDMapperFactory

Parameters:

catalog -

schema -

tableName -

connection - the active database connection to get table key information

Returns:

the appropriate FIDMapper for the specified table.

Throws:

java.io.IOException - if any error occurs.

isAutoIncrement

protected boolean isAutoIncrement(java.lang.String catalog,
                                  java.lang.String schema,
                                  java.lang.String tableName,
                                  java.sql.Connection conn,
                                  java.sql.ResultSet tableInfo,
                                  java.lang.String columnName,
                                  int dataType)
                           throws java.sql.SQLException

Determine whether this column is autoincrement. An open connection to the database must be provided.

Overrides:

isAutoIncrement in class DefaultFIDMapperFactory

Parameters:

catalog - not used

schema - not used

tableName - the table name

conn - an open database connection

tableInfo - not used

columnName - the FID column name

dataType - not used

Returns:

true if this is an autoincrement column

Throws:

java.sql.SQLException

buildNoPKMapper

protected FIDMapper buildNoPKMapper(java.lang.String schema,
                                    java.lang.String tableName,
                                    java.sql.Connection connection)

Returns a DB2NullFIDMapper when there is no primary key.

Overrides:

buildNoPKMapper in class DefaultFIDMapperFactory

Parameters:

schema - ignored.

tableName - ignored.

connection - ignored.

Returns:

a DB2NullFIDMapper.

buildSingleColumnFidMapper0

protected FIDMapper buildSingleColumnFidMapper0(java.lang.String schema,
                                                java.lang.String tableName,

                                                DefaultFIDMapperFactory.ColumnInfo ci)

Builds a FID mapper based on a single column primary key. Default version tries the auto-increment way, then a mapping on an MaxIncFIDMapper type for numeric columns, and a plain BasicFIDMapper of text based columns.

Parameters:

schema -

tableName -

connection - not used

ci - the column information

Returns:

a FIDMapper
