Class SerializableWrapper

java.lang.Object
oracle.eclipselink.coherence.integrated.internal.cache.SerializableWrapper

All Implemented Interfaces:

java.io.Serializable, Wrapper, WrapperInternal

public class SerializableWrapper

extends java.lang.Object

implements WrapperInternal

Purpose: This class is used as a generic wrapper class for non POF serialization. It provides for serialization to a node which may not have the correct dynamic wrapper defined which would otherwise result in an exception.

wrap

public void wrap(java.lang.Object entity)

Description copied from interface: Wrapper

This method is used to store the Entity within the wrapper.

Specified by:

wrap in interface Wrapper

Specified by:

wrap in interface WrapperInternal

getForeignKeyValuesFor

public java.lang.Object[] getForeignKeyValuesFor(java.lang.String propertyName)

Description copied from interface: Wrapper

This method provides access to the foreign key values for the related entities. If users are accessing caches from a non EclipseLink client then this will provide the information to query for related entities. These values will exist for all relationships including non-owned relationships. This method returns an org.eclipse.persistence.sessions.Record where the contents are the FK values.

Specified by:

getForeignKeyValuesFor in interface Wrapper

getPrimaryKeyValuesFor

public java.lang.Object[] getPrimaryKeyValuesFor(java.lang.String propertyName)

Description copied from interface: Wrapper

This method provides access to the primary key values for the related entities. If users are accessing caches from a non EclipseLink client then this will provide the information to load related entities from other caches. These values will exist for all relationships including non-owned relationships. This method returns an Object[] where the contents of the nested array is the PK values in order of the EclipseLink Class Descriptor's PK mappings.

Specified by:

getPrimaryKeyValuesFor in interface Wrapper

setForeignKeyValuesFor

public void setForeignKeyValuesFor(java.lang.String propertyName,
                                   java.lang.Object[] fks)

Description copied from interface: Wrapper

This method provides access to the foreign key values for queries of the related entities. If users are accessing caches from a non EclipseLink client then this will provide the information to query related entities. These values will exist for all relationships including non-owned relationships. This method takes and Object[] of FK values in the order of the EclipseLink mappings.

Specified by:

setForeignKeyValuesFor in interface Wrapper

setPrimaryKeyValuesFor

public void setPrimaryKeyValuesFor(java.lang.String propertyName,
                                   java.lang.Object[] pks)

Description copied from interface: Wrapper

This method provides access to the primary key values for the related entities. If users are accessing caches from a non EclipseLink client then this will provide the information to store related entities PKs for caches. These values will exist for all relationships including non-owned relationships. This method takes an Object[] where the contents of the nested array is the PK values for an Entity.

Specified by:

setPrimaryKeyValuesFor in interface Wrapper

unwrap

public java.lang.Object unwrap()

Description copied from interface: Wrapper

This method provides an access point for the wrapped entity. This method should be used by custom Value Extractors.

Specified by:

public java.lang.String getWrapperClassName()

Specified by:

getWrapperClassName in interface WrapperInternal

setWrapperClassName

public void setWrapperClassName(java.lang.String wrapperClassName)

Specified by:

setWrapperClassName in interface WrapperInternal

shouldMerge

public boolean shouldMerge()

Description copied from interface: WrapperInternal

This method indicates whether Wrapper stored into cache should be merged into the database.

Specified by:

shouldMerge in interface WrapperInternal
