Method Details

setColumnUnavailableValues

public static void setColumnUnavailableValues(Object[] columnValues,
 Table table)

Set the unavailable value placeholder in the column value array for null LOB-based columns.

Parameters:

columnValues - the column values array, should not be null

table - the relational model table, should not be null

getColumnUnavailableValue

public static Object getColumnUnavailableValue(Object value,
 Column column)

Resolve the column value for a given column value and column instance.

If the column value is null and the column is an LOB or XML-based column, this method will resolve the final column value as OracleValueConverters.UNAVAILABLE_VALUE, a value that represents that the column should be emitted with the unavailable value placeholder.

If the column value is not null or is not an LOB-based column, the method will simply return the column's value as-is without modification.

Parameters:

value - the column's value, may be null

column - the relational model's column instance, should not be null

Returns:

the resolved column's value
