Method Detail

getSerializedField

public java.lang.String[] getSerializedField(DatabaseConnector connector,
                                    java.sql.ResultSet rs,
                                    java.lang.String colname)

Provides the serialized representation of a given database field value.

The result set must be open and updatable and the column must exist. Remember that only the JDBC types supported by the JDBCConfiguration class may be used here.

Parameters:

connector - The connector responsible for type mapping

rs - The result set to get the native value

colname - The column name to process

Returns:

Index 0 is the serialized value, index 1 = Java type in FQN, null indicates error

Throws:

java.lang.IllegalArgumentException - If a parameter is invalid

Since:

1.6

updateSerializedField

public boolean updateSerializedField(DatabaseConnector connector,
                            java.sql.ResultSet rs,
                            java.lang.String colname,
                            java.lang.String value)

Updates a database field based on the given serialized value and column type.

The result set must be open and updatable and the column must exist. Remember that only the JDBC types supported by the JDBCConfiguration class may be used here.

Parameters:

connector - The connector responsible for type mapping

rs - The result set to update the field

colname - The column name to update

value - The serialized field value

Returns:

Successful?

Throws:

java.lang.IllegalArgumentException - If a parameter is invalid

Since:

1.6
