All known Subclasses: org.cougaar.logistics.ldm.ClassIConsumerPrototypeProvider, org.cougaar.logistics.ldm.PartsPrototypeProvider, org.cougaar.logistics.ldm.MEIPrototypeProvider, org.cougaar.logistics.ldm.ClassIPartsPrototypeProvider,
| QueryLDMPlugin | | abstract public class QueryLDMPlugin extends LDMEssentialPlugin (Code) | | Provides wrappers around the query routines. Takes care of a few LDMPlugin calls. Expects to have one Plugin argument
- the name of the file describing the queries ex. SpecialQueryLDMPlugin(specialQueryDescription.q)
See Also: QueryLDMPlugin.parseQueryFile(String queryFile)
See Also: for a description of the query file. |

Called by getPrototype() to actually create the prototype. | | protected Asset | newAsset(String typeid, String type, String nomenclature)
Calls LDM factory to create prototype and set nomenclature and alternameTypeIdentification. | | protected void | parseArguments()
| | protected void | parseQueryFile(String queryFile)
parses query file into local hashtable
Parameters:
queryFile - name of query file The query file is expected to be in the format param_name=param_value Thenecessary parameters are: Database, Driver, Username, Password Some parameters are not currentlyused, but may be in the future. | | protected void | parseQueryLine(String s)

|
| canHandle | | abstract public boolean canHandle(String typeid, Class class_hint)(Code) | | quick check for all things it should be able to handle
|
| executeQuery | | public Vector executeQuery(String query)(Code) | | Vector of results or null (on failure) |
| executeQuery | | public void executeQuery(String query, RowHandler rh)(Code) | | Less expensive variation on executeQuery(String) *
|
| getPrototype | | public Asset getPrototype(String aTypeName, Class anAssetClassHint)(Code) | | calls makePrototype(). calls fillProperties(). caches result
|
| initializeDriver | | protected void initializeDriver()(Code) | | |
| newAsset | | protected Asset newAsset(String typeid, String type, String nomenclature)(Code) | | Calls LDM factory to create prototype and set nomenclature and alternameTypeIdentification.
Parameters:
typeid - type identification of desired asset
Parameters:
type - the class name of the desired asset
Parameters:
nomenclature - * |
| parseArguments | | protected void parseArguments()(Code) | | |
| parseQueryFile | | protected void parseQueryFile(String queryFile)(Code) | | parses query file into local hashtable
Parameters:
queryFile - name of query file The query file is expected to be in the format param_name=param_value Thenecessary parameters are: Database, Driver, Username, Password Some parameters are not currentlyused, but may be in the future. These inclue MIN_IN_POOL, MAX_IN_POOL, TIMEOUT, andNUMBER_OF_TRIES. The rest of the lines are expected to be the query statements. Here is an examplefrom icisParts.q. Database = ${org.cougaar.database} Username = ${icis.database.user} Password =${icis.database.password} MIN_IN_POOL= 1 MAX_IN_POOL= 4 TIMEOUT= 1 NUMBER_OF_TRIES= 2headerQuery=select commodity, nsn, nomenclature, ui, ssc, price, icc, alt, plt, pcm, boq, diq,iaq, nso, qfd, rop, owrmrp, weight, cube, aac, slq from header where NSN = :nsnsassetsQuery=select nsn, ric, purpose, condition, iaq from assets where NSN = :nsns nomen=selectnomenclature from header where NSN = :nsns cost=select price from header where NSN = :nsns |
