Method Detail

toServiceTypeBase

public static ServiceTypeBase toServiceTypeBase(Class cls)
                                         throws MarshalException

Returns a ServiceTypeBase descriptor for a class.

Throws:

MarshalException

toServiceTypeBase

private static ServiceTypeBase toServiceTypeBase(Class cls,
                                                 boolean needCodebase)
                                          throws MarshalException

Returns a ServiceTypeBase descriptor for a class. If needCodebase is false, the returned descriptor's codebase may be null.

Throws:

MarshalException

toServiceType

private static ServiceType toServiceType(Class cls)
                                  throws MarshalException

Returns a ServiceType descriptor for a class.

Throws:

MarshalException

toServiceType

public static ServiceType[] toServiceType(Class[] classes)
                                   throws MarshalException

Converts an array of Class to an array of ServiceType.

Throws:

MarshalException

toEntryClassBase

public static EntryClassBase toEntryClassBase(Class cls)
                                       throws MarshalException

Returns a EntryClassBase descriptor for a class.

Throws:

MarshalException

toEntryClassBase

private static EntryClassBase toEntryClassBase(Class cls,
                                               boolean base)
                                        throws MarshalException

Returns a EntryClassBase descriptor for a class. If base is false, the returned descriptor's codebase may be null, and the class need not be public and need not have a no-arg constructor.

Throws:

MarshalException

toEntryClass

private static EntryClass toEntryClass(Class cls)
                                throws MarshalException

Returns an EntryClass descriptor for a class.

Throws:

MarshalException

getFields

public static ClassMapper.EntryField[] getFields(Class cls)

Returns public fields, in super to subclass order, sorted alphabetically within a given class.
