| Field Summary | |
| final protected static int | EXPORT
| | final protected static int[] | FK_INDEXES
| | final protected static int | IMPORT
| | final protected static int[] | PK_INDEXES
| | final protected static int[] | TABLENAME_INDEXES
indexes of the column names on the MetaData result sets. |
| Method Summary | |
| protected static ForeignKeyRelationshipEdge | createFKEdge(ResultSet rs, int type, String from, String to, String fkColumn, String pkColumn)
| | public IDatabaseConnection | getConnection()
Get the connection where the edges will be calculated from. | | protected SortedSet | getNodesFromExportedKeys(Object node)
Get the nodes using the reverse foreign key dependency, i.e, if table C has
a FK for a table A, then getNodesFromExportedKeys(A) will return C.
NOTE: this method should be used only as an auxiliary
method for sub-classes that also use getNodesFromImportedKeys()
or something similiar, otherwise the generated sequence of tables might not
work when inserted in the database (as some tables might be missing). | | protected SortedSet | getNodesFromImportAndExportKeys(Object node)
Get the nodes using the both direct and reverse foreign key dependency, i.e,
if table C has a FK for a table A and table A has a FK for a table B, then
getNodesFromImportAndExportedKeys(A) will return B and C. | | protected SortedSet | getNodesFromImportedKeys(Object node)
Get the nodes using the direct foreign key dependency, i.e, if table A has
a FK for a table B, then getNodesFromImportedKeys(A) will return B. | | protected IEdge | newEdge(ResultSet rs, int type, String from, String to, String fkColumn, String pkColumn)
This method can be overwritten by the sub-classes if they need to decorate
the edge (for instance, providing an Edge that contains the primary and
foreign keys used). |

| AbstractMetaDataBasedSearchCallback | | public AbstractMetaDataBasedSearchCallback(IDatabaseConnection connection)(Code) | | Defautl constructor.
Parameters:
connection - connection where the edges will be calculated from |
| createFKEdge | | protected static ForeignKeyRelationshipEdge createFKEdge(ResultSet rs, int type, String from, String to, String fkColumn, String pkColumn) throws SearchException(Code) | | Creates an edge representing a foreign key relationship between 2 tables.
Parameters:
rs - database meta-data result set
Parameters:
type - type of relationship (IMPORT or EXPORT)
Parameters:
from - name of the table representing the 'from' node
Parameters:
to - name of the table representing the 'to' node
Parameters:
fkColumn - name of the foreign key column
Parameters:
pkColumn - name of the primary key column edge representing the relationship between the 2 tables, according to the type
throws:
SearchException - not thrown in this method (but might on sub-classes) |

getNodesFromImportAndExportedKeys(A) will return B and C.
Parameters:
node - table name tables with reverse and direct FK dependency from node
throws:
SearchException - |
| getNodesFromImportedKeys | | protected SortedSet getNodesFromImportedKeys(Object node) throws SearchException(Code) | | Get the nodes using the direct foreign key dependency, i.e, if table A has
a FK for a table B, then getNodesFromImportedKeys(A) will return B.
Parameters:
