Class NodeAnnotationLink

java.lang.Object

ome.model.annotations.NodeAnnotationLink

All Implemented Interfaces:

java.io.Serializable, IAnnotationLink, ILink, IMutable, IObject, Filterable

@Entity
 @Indexed(index="FullText")
 @ClassBridge(name="details",
             impl=DetailsFieldBridge.class,
             index=UN_TOKENIZED,
             store=NO)
public class NodeAnnotationLink
extends java.lang.Object
implements java.io.Serializable, IObject, IMutable, IAnnotationLink

These filter definitions are used by the security system to eliminate non-readable objects from queries. The regular user does not need to worry about them, as they will be injected directly into the SQL (not HQL)

Method Detail

getId

@DocumentId
public java.lang.Long getId()

The DB unique identifier for this object. You are not responsible for setting the id; however, it can be useful for creating "unloaded" versions of your objects. Each top-level entity contains an id field of type long. For all objects returned from the server, this value will be non-null, which doesn't necessarily hold for the other fields.

Specified by:

getId in interface IObject

Returns:

Long primary key. May be null.

setId

public void setId(java.lang.Long id)

Description copied from interface: IObject

usually unneeded. Ids are managed by the backend.

Specified by:

setId in interface IObject

Parameters:

id - Long value for this id.

getVersion

public java.lang.Integer getVersion()

This version number is controlled by the database for optimisitic locking.

Specified by:

getVersion in interface IMutable

setVersion

public void setVersion(java.lang.Integer version)

Description copied from interface: IMutable

use with caution. In general, the version should only be altered by the backend. In the best case, an exception will be thrown for a version not equal to the current DB value. In the worst (though rare) case, the new version could match the database, and override optimistic lock checks that are supposed to prevent data loss.

Specified by:

setVersion in interface IMutable

Parameters:

version - Value for this objects version.

getParent

public IObject getParent()

Many-to-one field ome.model.annotations.NodeAnnotationLink.parent (ome.model.meta.Node)

Specified by:

getParent in interface ILink

setParent

public void setParent(IObject parent)

Specified by:

setParent in interface ILink

getChild

public IObject getChild()

Many-to-one field ome.model.annotations.NodeAnnotationLink.child (ome.model.annotations.Annotation)

Specified by:

getChild in interface ILink

setChild

public void setChild(IObject child)

Specified by:

setChild in interface ILink

getDetails

public Details getDetails()

The details of this object correspond to low-level system information. Owner, permissions, Details is always guaranteed to be non-null, unless the user actively nulls it. Every entity also contains a Detail reference, which doesn't refer to a separate table but rather to a collection of fields collected into a Hibernate "component" which is embedded in the object. HQL queries which refer to the Details component cannot directly fetch the entity like this: select o from Object join fetch o.details but rather each field of the Details instance must be explicitly joined: select o from Object join fetch o.details.owner It should also be noted that not all types have all the fields which are present on Details. For example, select e from Experimenter e join fetch e.details.owner will fail. Experimenter has no owner, for obvious reasons. Note: subclasses of this class will return a subclass of the Details type.

Specified by:

getDetails in interface IObject

setDetails

protected void setDetails(Details details)

isValid

public boolean isValid()

Description copied from interface: IObject

calls the class-specific validator for this instance and returns the value from Validation.isValid()

Specified by:

isValid in interface IObject

validate

public Validation validate()

Description copied from interface: IObject

calls the class-specific validator for this instance and returns the Validation object.

Specified by:

validate in interface IObject

Returns:

Validation collecting parameter.

newInstance

public NodeAnnotationLink newInstance()

proxy

public NodeAnnotationLink proxy()

acceptFilter

public boolean acceptFilter(Filter __filter)

Specified by:

acceptFilter in interface Filterable

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

fields

public java.util.Set<java.lang.String> fields()

Description copied from interface: IObject

returns a Set of field names that belong to this class

Specified by:

fields in interface IObject

retrieve

public java.lang.Object retrieve(java.lang.String field)

Description copied from interface: IObject

retrieves a value from this instance. Values for field which match a field of this instance will be delegated to the accessors. Otherwise, values will be retrieved from a lazy-loaded map filled by calls to IObject.putAt(String, Object)

Specified by:

retrieve in interface IObject

putAt

public void putAt(java.lang.String field,
                  java.lang.Object value)

Description copied from interface: IObject

stores a value in this instance. Values for field which match a field of this instance will be delegated to the accessors. Otherwise, values will be stored in a lazy-loaded map.

Specified by:

putAt in interface IObject

Parameters:

field - Field name

value - Any object to be stored.

isLoaded

public boolean isLoaded()

Description copied from interface: IObject

transient field (not stored in the DB) which specifies whether this object has been loaded from the DB or is only a wrapper around the ID.

Specified by:

isLoaded in interface IObject

errorIfUnloaded

protected void errorIfUnloaded()

unload

public void unload()

Description copied from interface: IObject

set the loaded field to false, and set all non-ID fields to null. Subsequent calls to all accessors other than getId/setId will throw an ApiUsageException

Specified by:

unload in interface IObject

getGraphHolder

public final GraphHolder getGraphHolder()

Description copied from interface: IObject

retrieves the GraphHolder for this entity. If the GraphHolder has not been actively set, a new one will be instatiated.

Specified by:

getGraphHolder in interface IObject

Returns:

Non-null GraphHolder

throwNullCollectionException

protected void throwNullCollectionException(java.lang.String propertyName)

link

public void link(Node parent,
                 Annotation child)

parent

public Node parent()

child

public Annotation child()
