Constructor Detail

EntityBranch

public EntityBranch(EntityStore es,
                    ESPK branchRootPK)
             throws EntityStoreException

Throws:

EntityStoreException

EntityBranch

public EntityBranch(EntityStore es,
                    ESPK branchRootPK,
                    java.util.Set<ESPK> pks)
             throws EntityStoreException

Create a branch of the entity hierarchy from a given store and starting point.

Parameters:

es - The entity store from which to take the branch image

branchRootPK - The ESPK of the root Entity of the branch

pks - The original ESPKs of each of the Entities which were traversed to generate this branch

Throws:

EntityStoreException - If there are any problems traversing the branch.

Method Detail

createNode

protected EntityBranch.EntityNode createNode(Entity e)

isCompatibleGraftPoint

public boolean isCompatibleGraftPoint(Entity e)

graftTo

public ESPK graftTo(EntityStore store,
                    ESPK espk,
                    java.util.Set<PortableESPK> unresolved,
                    java.util.Set<ESPK> newPKs)
             throws EntityStoreException

Parameters:

store - The EntityStore on which to operate.

espk - The Entity under which the branch will be grafted.

unresolved - A holder for normalized references to links which could not be resolved following a graft.

newPKs - A holder for the new Entities' PKs. May be null if caller is not interested.

Returns:

The ESPK of the new root Entity for this branch graft.

Throws:

EntityStoreException - If an equivalent root node already exists at the graft point.

doGraft

protected ESPK doGraft(EntityStore store,
                       ESPK espk,
                       java.util.Set<PortableESPK> unresolved,
                       java.util.Set<ESPK> newPKs)
                throws EntityStoreException

Throws:

EntityStoreException

resetRoot

public void resetRoot()
