public class ArrayAccessor
extends DirectAccessor

An array accessor. Used to support ArrayMapping and ObjectArrayMapping. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - any metadata mapped from XML to this class must be initialized in the initXMLObject 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 2.3

Constructor Detail

ArrayAccessor

public ArrayAccessor()

INTERNAL: Used for OX mapping.

ArrayAccessor

public ArrayAccessor(MetadataAnnotation array,
                     MetadataAccessibleObject accessibleObject,
                     ClassAccessor classAccessor)

INTERNAL: Used for annotations.

Method Detail

equals

public boolean equals(java.lang.Object objectToCompare)

INTERNAL:

Overrides:

equals in class DirectAccessor

getColumn

public ColumnMetadata getColumn()

INTERNAL: Used for OX mapping.

getDatabaseType

public java.lang.String getDatabaseType()

INTERNAL: Used for OX mapping.

getDefaultFetchType

public java.lang.String getDefaultFetchType()

INTERNAL:

Specified by:

getDefaultFetchType in class DirectAccessor

getEmbeddableAccessor

public EmbeddableAccessor getEmbeddableAccessor()

INTERNAL:

getReferenceClass

public MetadataClass getReferenceClass()

If a targetClass is specified in metadata, it will be set as the reference class, otherwise we will look to extract one from generics.

MappedSuperclass descriptors return Void when their parameterized generic reference class is null

Overrides:

getReferenceClass in class MappingAccessor

getReferenceDescriptor

public MetadataDescriptor getReferenceDescriptor()

In an element collection case, when the collection is not an embeddable collection, there is no notion of a reference descriptor, therefore we return this accessors descriptor

Overrides:

getReferenceDescriptor in class MappingAccessor

initXMLObject

public void initXMLObject(MetadataAccessibleObject accessibleObject,
                          XMLEntityMappings entityMappings)

INTERNAL:

Overrides:

initXMLObject in class DirectAccessor

isDirectEmbeddableCollection

public boolean isDirectEmbeddableCollection()

INTERNAL: Return true if this element collection contains embeddable objects.

Overrides:

isDirectEmbeddableCollection in class MappingAccessor

process

public void process()

INTERNAL: Process the ArrayMapping or ObjectArrayMapping.

Specified by:

process in class MetadataAccessor

setColumn

public void setColumn(ColumnMetadata column)

INTERNAL: Used for OX mapping.

setDatabaseType

public void setDatabaseType(java.lang.String databaseType)

INTERNAL: Used for OX mapping.

setTargetClassName

public void setTargetClassName(java.lang.String targetClassName)

INTERNAL: Used for OX mapping.
