Field Detail

collection

protected java.util.Collection collection

is the internal collection used when the gen class is not active. When the proxy is active the 'elements' field is used.

Constructor Detail

CollectionAccessor

public CollectionAccessor(SpeedoGenClassProxy _jdoProxy)

Instanciates and initializes a new collection with an initial size.

Method Detail

toString

public java.lang.String toString()

duplicatAllowed

speedoRemove2

public GenClassElement speedoRemove2(java.lang.Object o)

makePersistent

public void makePersistent(ProxyManager pm)

Description copied from interface: SpeedoAccessor

Makes persistent all inner elements of the persistent instance. For a class, it means making persistent all objects referenced by a persistent field. For a genclass it means making persistent element of the genclass. This method is called when a makePersistent is called on the persistent class (Proxy) linked to this accessor.

Specified by:

makePersistent in interface SpeedoAccessor

Specified by:

makePersistent in class GenClassAccessor

deletePersistent

public void deletePersistent(ProxyManager pm)

Description copied from interface: SpeedoAccessor

Deletes persistent all inner elements of the persistent instance. For a class, it means deleting persistent all objects referenced by a persistent field. For a genclass it means deleting persistent element of the genclass. This method is called when a deletePersistent is called on the persistent class (Proxy) linked to this accessor.
