Constructor Detail

DatabaseReadOnlyNetwork

public DatabaseReadOnlyNetwork(javax.persistence.EntityManager entityManager,
                               boolean isShortTerm)

Method Detail

isReadOnly

public boolean isReadOnly()

Specified by:

isReadOnly in interface Network

Overrides:

isReadOnly in class AbstractNetwork

resume

public void resume()

Resume the network after a save. Keep the MAX_SIZE number of most conscious vertices in memory.

Specified by:

resume in interface Network

Overrides:

resume in class DatabaseNetwork

executeNativeQuery

public int executeNativeQuery(java.lang.String sql)

Execute and commit the native query.

Specified by:

executeNativeQuery in interface Network

Overrides:

executeNativeQuery in class DatabaseNetwork

executeQuery

public int executeQuery(java.lang.String jpql)

Execute and commit the update query.

Specified by:

executeQuery in interface Network

Overrides:

executeQuery in class DatabaseNetwork

save

public void save()

Commit memory to the database.

Specified by:

save in interface Network

Overrides:

save in class DatabaseNetwork

addVertex

public void addVertex(Vertex vertex)

Add the existing vertex to the network. Used to load an existing vertex, createVertex must be used to create a new one.

Specified by:

addVertex in interface Network

Overrides:

addVertex in class DatabaseNetwork

createVertex

public Vertex createVertex(java.lang.Object data)

Find the exiting vertex, or create a temporary one for primitives.

Specified by:

createVertex in interface Network

Overrides:

createVertex in class AbstractNetwork

saveProperty

public void saveProperty(java.lang.String propertyName,
                         java.lang.String value,
                         boolean startup)

Save the property setting to the current transaction.

Specified by:

saveProperty in interface Network

Overrides:

saveProperty in class DatabaseNetwork

removeProperty

public void removeProperty(java.lang.String propertyName)

Remove the property setting to the current transaction.

Specified by:

removeProperty in interface Network

Overrides:

removeProperty in class DatabaseNetwork

removeVertex

public void removeVertex(Vertex vertex)

Remove the vertex from the network. Note that the vertex must be no longer referenced by any other vertex in the network.

Specified by:

removeVertex in interface Network

Overrides:

removeVertexAndReferences

public void removeVertexAndReferences(Vertex vertex)

Remove the vertex and all references to it from the network.

Specified by:

removeRelationship

public void removeRelationship(Relationship relationship)

Remove the relationship from the network. Note that the relationship must be no longer referenced by any other vertex in the network.

Specified by:

removeRelationship in interface Network

Overrides:

removeRelationship in class DatabaseNetwork

setHints

public void setHints(javax.persistence.Query query)

Overrides:

setHints in class DatabaseNetwork

findByData

public Vertex findByData(java.lang.Object data)

Return the vertex with the given data.

Specified by:

findByData in interface Network

Overrides:

findByData in class DatabaseNetwork

findById

public Vertex findById(java.lang.Number id)
