Class OverrideMetadata

java.lang.Object

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

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

Direct Known Subclasses:

AssociationOverrideMetadata, AttributeOverrideMetadata

public abstract class OverrideMetadata
extends ORMetadata

INTERNAL: Object to hold onto common attribute/association override metadata. 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 1.0

Method Detail

equals

public boolean equals(java.lang.Object objectToCompare)

INTERNAL:

Specified by:

equals in class ORMetadata

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getIdentifier

public java.lang.String getIdentifier()

INTERNAL: To satisfy the MetadataMergeable interface for subclasses and provide a means of uniquely identifying objects.

Overrides:

getIgnoreMappedSuperclassContext

public abstract java.lang.String getIgnoreMappedSuperclassContext()

INTERNAL:

getName

public java.lang.String getName()

INTERNAL: Used for OX mapping.

setName

public void setName(java.lang.String name)

INTERNAL: Used for OX mapping.

shouldOverride

public boolean shouldOverride(OverrideMetadata existing,
                              MetadataLogger logger,
                              java.lang.String descriptorClass)

INTERNAL: Method to determine if this ORMetadata should override another. Assumes all ORMetadata have correctly implemented their equals method and will return their correct logging context for any ignore messages. This is called on class level override metadata (and not those from an embedded mapping).
