| public boolean | isOneToMany()INTERNAL:
return true;
|
| public void | process()INTERNAL:
Process an @OneToMany or one-to-many element into a TopLink OneToMany
mapping. If a JoinTable is found however, we must create a ManyToMany
mapping.
String mappedBy = getMappedBy();
// Should be treated as a uni-directional mapping using a join table.
if (mappedBy.equals("")) {
// If we find a JoinColumn(s), then throw an exception.
if (hasJoinColumn() || hasJoinColumns()) {
getValidator().throwUniDirectionalOneToManyHasJoinColumnSpecified(getAttributeName(), getJavaClass());
}
// Create a M-M mapping and process common collection mapping
// metadata.
ManyToManyMapping mapping = new ManyToManyMapping();
process(mapping);
// Process the @JoinTable.
processJoinTable(getJoinTable(), mapping);
// Add the mapping to the descriptor.
m_descriptor.addMapping(mapping);
} else {
// Create a 1-M mapping and process common collection mapping
// metadata.
OneToManyMapping mapping = new OneToManyMapping();
process(mapping);
// Non-owning side, process the foreign keys from the owner.
OneToOneMapping ownerMapping = null;
if (getOwningMapping().isOneToOneMapping()){
ownerMapping = (OneToOneMapping) getOwningMapping();
} else {
// If improper mapping encountered, throw an exception.
getValidator().throwInvalidMappingEncountered(getJavaClass(), getReferenceClass());
}

mapping.addTargetForeignKeyField(fkField, keys.get(fkField));
}
// Add the mapping to the descriptor.
m_descriptor.addMapping(mapping);
