Class SizedForBitDataDomain

java.lang.Object
  org.apache.torque.engine.database.model.Domain
      org.apache.torque.engine.database.model.SizedForBitDataDomain

public class SizedForBitDataDomain
extends Domain

Supports the Derby / DB2 / SQL92 standard for defining Binary data fields with either CHAR(#) FOR BIT DATA or VARCHAR(#) FOR BIT DATA. This can be used in Platform implimentors initialize() methods, by using lines like:

setSchemaDomainMapping(new SizedForBitDataDomain( SchemaType.BINARY, "CHAR", "1")); setSchemaDomainMapping(new SizedForBitDataDomain( SchemaType.VARBINARY, "VARCHAR"));

This will cause the Column.getSqlString() method to produce items similar to:

CHAR(#) FOR BIT DATA VARCHAR(#)FOR BIT DATA

Where: # is the size= schema attribute or a default size specified in the constructor.

Note that this is dependent on the platform implimentation correctly defining BINARY and VARBINARY as having a size attribute in the "hasSize()" method.
