Constructor Detail

EmbeddedFieldMeta

protected EmbeddedFieldMeta()

EmbeddedFieldMeta

public EmbeddedFieldMeta(EmbeddedClassMeta classMeta,
                         EmbeddedFieldMeta ownerFieldMeta,
                         FieldMeta nonEmbeddedFieldMeta)
Method Detail

getClassMeta

public EmbeddedClassMeta getClassMeta()
Description copied from class: FieldMeta
Get the ClassMeta to which this FieldMeta belongs. Every FieldMeta belongs to exactly one ClassMeta just like a field is declared in exactly one Java class. Note, that a FieldMeta might belong to another FieldMeta in order to reference sub-field-properties, e.g. a Map's key. In this case, the direct property classMeta is null, but this method still returns the correct ClassMeta by resolving it indirectly via the ownerFieldMeta.

Overrides:
getClassMeta in class FieldMeta
Returns:
the ClassMeta to which this instance of FieldMeta belongs.

addSubFieldMeta

public void addSubFieldMeta(FieldMeta subFieldMeta)
Overrides:
addSubFieldMeta in class FieldMeta

setClassMeta

protected void setClassMeta(ClassMeta classMeta)
Overrides:
setClassMeta in class FieldMeta

setOwnerFieldMeta

protected void setOwnerFieldMeta(FieldMeta ownerFieldMeta)
Overrides:
setOwnerFieldMeta in class FieldMeta

getNonEmbeddedFieldMeta

public FieldMeta getNonEmbeddedFieldMeta()

getEmbeddingFieldMeta

public FieldMeta getEmbeddingFieldMeta()
Get the field which is embedding the object having this field.

This is a convenience method for getClassMeta().getEmbeddingFieldMeta().

Returns:
the field which is embedding the object having this field. Never null.

jdoPostDetach

public void jdoPostDetach(Object o)
Specified by:
jdoPostDetach in interface DetachCallback
Overrides:
jdoPostDetach in class FieldMeta

setNonEmbeddedFieldMetaPostponed

protected void setNonEmbeddedFieldMetaPostponed(PostDetachRunnableManager postDetachRunnableManager,
                                                DetachedClassMetaModel detachedClassMetaModel,
                                                FieldMeta nonEmbeddedFieldMeta,
                                                int postponeCounter)

getDataNucleusAbsoluteFieldNumber

public int getDataNucleusAbsoluteFieldNumber(ExecutionContext executionContext)
Overrides:
getDataNucleusAbsoluteFieldNumber in class FieldMeta

getDataNucleusAbsoluteFieldNumber

public int getDataNucleusAbsoluteFieldNumber()
Description copied from class: FieldMeta
Get the non-persistent field-number in DataNucleus' meta-data. This is only a usable value, if this FieldMeta was obtained via Cumulus4jStoreManager.getClassMeta(org.datanucleus.store.ExecutionContext, Class); otherwise it is -1.

Overrides:
getDataNucleusAbsoluteFieldNumber in class FieldMeta
Returns:
the non-persistent field-number in DataNucleus' meta-data or -1.

setDataNucleusAbsoluteFieldNumber

public void setDataNucleusAbsoluteFieldNumber(int dataNucleusAbsoluteFieldNumber)
Overrides:
setDataNucleusAbsoluteFieldNumber in class FieldMeta

getDataNucleusMemberMetaData

public AbstractMemberMetaData getDataNucleusMemberMetaData(ExecutionContext executionContext)
Overrides:
getDataNucleusMemberMetaData in class FieldMeta

toString

public String toString()
Overrides:
toString in class FieldMeta
