boolean |
compatible(TypeId otherType)
Determine if this type is compatible to some other type
(e.g.
|
boolean |
convertible(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.

double |
estimatedMemoryUsage(DataTypeDescriptor dtd) |
int |
getCastToCharWidth(DataTypeDescriptor dts)
Return the maximum width for this data type when cast to a char type.
|
java.lang.String |
getCorrespondingPrimitiveTypeName()
Get the name of the corresponding Java type.
|
java.lang.String |
interfaceName()
Get the name of the interface for this type.
|
(package private) java.lang.String |
nullMethodName()
Return the method name to get a Derby DataValueDescriptor
object of the correct type set to SQL NULL.
|
boolean |
storable(TypeId otherType,
ClassFactory cf)
User types are storable into other user types that they
are assignable to.

- The CompilationType of the other type to compare

- true if this is a type function that
requires more liberal behavior (e.g DOUBLE can convert a char but
you cannot cast a CHAR to double.TypeCompiler.convertible(org.apache.derby.iapi.types.TypeId, boolean)
