Method Detail

setObject

public boolean setObject(FBField field,
                         java.lang.Object object)
                  throws java.sql.SQLException

If the object type is supported, and the object (or its conversion) is allowed by JDBC, it sets the field with the (converted) object.

As this method is - for the time being - intended as a workaround for JDBC 4.2, it specifically only supports new conversions in JDBC 4.2. It will return false for any other object type.

Parameters:

field - FBField implementation to set

object - The object value to set

Returns:

true when a conversion was applied, false when there is no conversion for the object and field

Throws:

java.sql.SQLException - For exceptions when setting the object on the field (eg unsupported conversion).

getObject

public <T> T getObject(FBField field,
                       java.lang.Class<T> type)
                throws java.sql.SQLException

Get object with the specified type.

As this method is - for the time being - intended as a workaround for JDBC 4.2, it specifically only supports new conversions in JDBC 4.2. It will return false for any other object type.

Type Parameters:

Parameters:

field - FBField implementation to set

type - Type conversion to get

Returns:

Value of the field in the specified type, or null when null.
