Returns:

a collection cmp ejb names

getFieldsForEjb

Collection getFieldsForEjb(String ejbName)

Gets a collection of names of cmp fields and cmr fields defined in this ejb jar for the specified ejb.

Parameters:

Returns:

a collection cmp and cmr field names

getRelationshipsForEjb

Collection getRelationshipsForEjb(String ejbName)

Gets a collection of names of cmr fields defined in this ejb jar for the specified ejb.

Parameters:

ejbName - the name of the ejb for which a list of cmr fields will be created

a collection cmr field names

getClassLoader

ClassLoader getClassLoader()

Gets the class loader which corresponds to this ejb jar. Implementations can return null if this is not relevant.

Returns:

getNameMapper

AbstractNameMapper getNameMapper()

Gets the AbstractNameMapper object to use for this helper.

Returns:

the name mapper object

createUniqueNameMapper

AbstractNameMapper createUniqueNameMapper()

Creates and returns an instance of the AbstractNameMapper object to use for generation of unique names with this helper.

Note that this method is a factory-like method which creates a new instance so the caller can make modifications to it as necessary.

Returns:

the name mapper object

createConversionHelper
