Type Parameters:

T - the Liquibase fallback type to use

public abstract class TypeWithFallbackType<T extends liquibase.datatype.LiquibaseDataType>
extends liquibase.datatype.LiquibaseDataType

Superclass for custom liquibase types adding additional behavior on top of existing ones. This class maintains a 'fallback' type, that will be used when the custom behavior should not be introduced. As custom Liquibase types will have different type names not to clash with the default ones and Liquibase will fallback to using the type's name if there is no special handling to introduce, simply extending from the LiquibaseDataType representing the base data type is not sufficient. To prevent Liquibase from trying to create a DDL with custom type's name as the column type, this class will use the fallback type's handling to generate the DDL.
