Class ReferencePersistTransformer<R extends AbstractReference>

java.lang.Object

com.neurosys.refs.transformers.ReferencePersistTransformer<R>

Type Parameters:

R -

All Implemented Interfaces:

Serializable, org.apache.commons.collections.Transformer

Direct Known Subclasses:

StringToReferenceTransformer

public class ReferencePersistTransformer<R extends AbstractReference>
extends Object
implements org.apache.commons.collections.Transformer, Serializable

Persist a Reference and all its relations like Reference#setParent(Reference) and Reference.setRelated(List).
Takes a Reference type and returns a Reference type.

By default it uses a JPAPersistTransformer transformer in persistTransformer.

Method Summary

Modifier and Type	Method and Description
protected Reference	deriveRelative(Object relatedRefType, String mainRefName)
Object	getParent() A List of References OR a Transformer that dynamically generates a parent Reference for each String token.
org.apache.commons.collections.Transformer	getPersistTransformer() The underlying Transformer to persist to data source
List	getRelated() A List of References OR a Transformer that dynamically generates a List of References for each String token. The List of Reference represented by this can be related using ReferenceAlias where ReferenceAlias#setReference(Reference) refers to the reference being created and ReferenceAlias#setRelated(Reference) refers to one of the related references.
boolean	isCreateRefIfNotExist() If true will create Reference.getParent() or ReferenceAlias.getRelated()
protected R	persistReference(R ref) Handle Persistence of the core Relation entity
protected AbstractReference	persistRelation(AbstractReference ref) Handle Persistence of Relation type, Reference#setParent(Reference) or Reference.setRelated(List)
void	setCreateRefIfNotExist(boolean createRefIfNotExist) If true will create Reference.getParent() or ReferenceAlias.getRelated()
void	setParent(Object parent) A List of References OR a Transformer that dynamically generates a parent Reference for each String token.
void	setPersistTransformer(org.apache.commons.collections.Transformer persistTransformer) The underlying Transformer to persist to data source
void	setRelated(List related) A List of References OR a Transformer that dynamically generates a List of References for each String token. The List of Reference represented by this can be related using ReferenceAlias where ReferenceAlias#setReference(Reference) refers to the reference being created and ReferenceAlias#setRelated(Reference) refers to one of the related references.
Object	transform(Object input)
protected R	transformRef(R ref)

protected R persistReference(R ref)

Handle Persistence of the core Relation entity

transformRef

protected final R transformRef(R ref)

transform

public Object transform(Object input)

Specified by:

transform in interface org.apache.commons.collections.Transformer

getParent

public Object getParent()

A List of References OR a Transformer that dynamically generates a parent Reference for each String token.

Can be null:

true

setParent

public void setParent(Object parent)

A List of References OR a Transformer that dynamically generates a parent Reference for each String token.

Can be null:

true

getRelated

public List getRelated()

A List of References OR a Transformer that dynamically generates a List of References for each String token.
The List of Reference represented by this can be related using ReferenceAlias where ReferenceAlias#setReference(Reference) refers to the reference being created and ReferenceAlias#setRelated(Reference) refers to one of the related references.

Can be null:

true

setRelated

public void setRelated(List related)

A List of References OR a Transformer that dynamically generates a List of References for each String token.
The List of Reference represented by this can be related using ReferenceAlias where ReferenceAlias#setReference(Reference) refers to the reference being created and ReferenceAlias#setRelated(Reference) refers to one of the related references.

Can be null:

true

isCreateRefIfNotExist

public boolean isCreateRefIfNotExist()

If true will create Reference.getParent() or ReferenceAlias.getRelated()

Default value:

false

setCreateRefIfNotExist

public void setCreateRefIfNotExist(boolean createRefIfNotExist)

If true will create Reference.getParent() or ReferenceAlias.getRelated()

Default value:

false

getPersistTransformer

public org.apache.commons.collections.Transformer getPersistTransformer()

The underlying Transformer to persist to data source

setPersistTransformer

public void setPersistTransformer(org.apache.commons.collections.Transformer persistTransformer)

The underlying Transformer to persist to data source
