Class MetadataColumn

java.lang.Object

org.eclipse.persistence.internal.jpa.metadata.ORMetadata

org.eclipse.persistence.internal.jpa.metadata.columns.MetadataColumn

Direct Known Subclasses:

DirectColumnMetadata, DiscriminatorColumnMetadata, RelationalColumnMetadata

public abstract class MetadataColumn
extends ORMetadata

INTERNAL: Object to process JPA column type into EclipseLink database fields.

Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - when loading from annotations, the constructor accepts the metadata accessor this metadata was loaded from. Used it to look up any 'companion' annotation needed for processing. - methods should be preserved in alphabetical order.

Since:

EclipseLink 1.2
