Method Details

isProxy

public boolean isProxy()
                throws RepositoryErrorException

Determine whether this entity is a proxy or not.

Returns:

boolean

Throws:

RepositoryErrorException - mapping problem

getEntityDetail

public EntityDetail getEntityDetail()
                             throws RepositoryErrorException

Construct an entity detail object using the values from the database.

Returns:

full entity description or null if the entity is not available

public EntityProxy getEntityProxy()
                           throws RepositoryErrorException

Construct an entity proxy object from the values from the database.

Returns:

entity proxy description

Throws:

RepositoryErrorException - problem mapping the properties

getEntityTableRow

public Map<String,JDBCDataValue> getEntityTableRow()
                                            throws RepositoryErrorException

Extract the entity table information from the entity object.

Returns:

entity table row for this entity

Throws:

RepositoryErrorException - problem mapping the properties

getEntityPropertiesTableRows

public List<Map<String,JDBCDataValue>> getEntityPropertiesTableRows()
