UserDefinedTypeCompiler
public class UserDefinedTypeCompiler extends BaseTypeCompiler (Code)




Method Summary
public  booleancomparable(TypeId otherType, boolean forEquals, ClassFactory cf)
     User types are comparable to other user types only if (for now) they are the same type and are being used to implement some JDBC type.
public  booleancompatible(TypeId otherType)
    
public  booleanconvertible(TypeId otherType, boolean forDataTypeFunction)
     User types are convertible to other user types only if (for now) they are the same type and are being used to implement some JDBC type.

public  booleanstorable(TypeId otherType, ClassFactory cf)
     User types are storable into other user types that they are assignable to.



Method Detail
comparable
public boolean comparable(TypeId otherType, boolean forEquals, ClassFactory cf)(Code)
User types are comparable to other user types only if (for now) they are the same type and are being used to implement some JDBC type. This is sufficient for date/time types; it may be generalized later for e.g. comparison of any user type with one of its subtypes.
Parameters:
  otherType - the type of the instance to compare with this type.
Parameters:
  forEquals - True if this is an = or <> comparison, falseotherwise.
Parameters:
  cf - A ClassFactory true if otherType is comparable to this type, else false.



compatible
public boolean compatible(TypeId otherType)(Code)

See Also:   TypeCompiler.compatible
See Also:   



convertible
public boolean convertible(TypeId otherType, boolean forDataTypeFunction)(Code)
User types are convertible to other user types only if (for now) they are the same type and are being used to implement some JDBC type. This is sufficient for date/time types; it may be generalized later for e.g. comparison of any user type with one of its subtypes.
Parameters:
  otherType -
Parameters:
  forDataTypeFunction - true if otherType is convertible to this type, else false.
See Also:   TypeCompiler.convertible



generateDataValue
public void generateDataValue(MethodBuilder mb, LocalField field)(Code)



getCastToCharWidth
public int getCastToCharWidth(DataTypeDescriptor dts)(Code)

See Also:   TypeCompiler.getCastToCharWidth



getCorrespondingPrimitiveTypeName
public String getCorrespondingPrimitiveTypeName()(Code)

See Also:   TypeCompiler.getCorrespondingPrimitiveTypeName



interfaceName
public String interfaceName()(Code)

See Also:   TypeCompiler.interfaceName
See Also:   



nullMethodName
protected String nullMethodName()(Code)



storable
public boolean storable(TypeId otherType, ClassFactory cf)(Code)
User types are storable into other user types that they are assignable to. The other type must be a subclass of this type, or implement this type as one of its interfaces. Built-in types are also storable into user types when the built-in type's corresponding Java type is assignable to the user type.
Parameters:
  otherType - the type of the instance to store into this type.
Parameters:
  cf - A ClassFactory true if otherType is storable into this type, else false.
