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
