Constructor Detail

TpaeIFConnector

public TpaeIFConnector()

Default constructor.

Method Detail

setConfiguration

public void setConfiguration(java.lang.Object config)

This method makes sure that InternalSchema.CONNECTOR_COMPUTE_CHANGES is set to false since compute changes logic is not supported for hierarchical entries yet.

Specified by:

setConfiguration in interface ConnectorInterface

Overrides:

setConfiguration in class Connector

Parameters:

config - The configuration object (an instance of ConnectorConfig)

initialize

public void initialize(java.lang.Object obj)
                throws java.lang.Exception

Initialize the connector. The connector may be passed a parameter of any kind by the user. It is up to the connector to determine whether this object can be used or not. The parameter is typically provided by a user script. When an AssemblyLine initializes it's Connectors, they are passed a ConnectorMode object.

Specified by:

initialize in interface ConnectorInterface

Overrides:

initialize in class SimpleTpaeIFConnector

Parameters:

obj - User provided parameter

Throws:

java.lang.Exception - if the initialization of this connector fails.

selectEntries

public void selectEntries()
                   throws MxConnectorException

Prepare the Connector for sequential read. If necessary, create a result set to be used for getNextEntry(). When the Connector is used as an Iterator in an AssemblyLine, this method will be called. Default is an empty method.

Specified by:

selectEntries in interface ConnectorInterface

Overrides:

selectEntries in class SimpleTpaeIFConnector

Throws:

MxConnectorException

getNextEntry

public Entry getNextEntry()
                   throws MxConnectorException

Returns the next Entry from the connector. The entry is populated with attributes and values from the next entry in the input set.

Example:

 var ctor = input.getConnector();
 var entry = ctor.getNextEntry();
 
 for (; entry != null; entry = ctor.getNextEntry()) {
        main.logmsg("Read entry...");
        main.dumpEntry(entry);
 }
 

Specified by:

getNextEntry in interface ConnectorInterface

Overrides:

getNextEntry in class SimpleTpaeIFConnector

Returns:

- the next Entry, or null if no more data

Throws:

MxConnectorException

See Also:

ConnectorInterface.selectEntries()

putEntry

public void putEntry(Entry newEntry)
              throws MxConnectorException

Adds a new entry to the data source

Example:

 var ctor = write.getConnector();
 
 for (i = 0; i < 10; i++) {
        var entry = system.newEntry();
        entry.setAttribute("linenumber", i);
        entry.setAttribute("line", i + " line of text...");
 
        main.logmsg("Writes entry to output...");
        main.dumpEntry(entry);
        ctor.putEntry(entry);
 }
 

Specified by:

putEntry in interface ConnectorInterface

Overrides:

putEntry in class SimpleTpaeIFConnector

Parameters:

newEntry - The entry data to add

Throws:

MxConnectorException

findEntry

public Entry findEntry(SearchCriteria searchCriteria)
                throws java.lang.Exception

Finds an existing entry. The search criteria specifies which entry to locate

Here is an example of how to find all people with names starting with 'J' which are from IBM organization in US.

Example:

 var ctor = input.getConnector();
 var crit = new com.ibm.di.SearchCriteria("$dn",
                com.ibm.di.SearchCriteria.SUBSTRING, "c=US,o=IBM");
 crit.addCriteria("name", com.ibm.di.SearchCriteria.INITIAL_STRING, "J");
 crit.addCriteria("objectclass", com.ibm.di.SearchCriteria.SUBSTRING, "person");
 
 var res = ctor.findEntry(crit);
 if (res != null) {
        main.logmsg("Found entry:");
        main.dumpEntry(res);
 } else {
  if( getFindEntryCount()> 1 ){
   main.logmsg("Found these entries:");
   while ( (entry = ctor.getNextFindEntry()) != null ) {
     main.dumpEntry(entry);
   }
  }
  else {
         main.logmsg("Entry not found!");
  }
 }
 

Specified by:

findEntry in interface ConnectorInterface

Overrides:

findEntry in class SimpleTpaeIFConnector

Parameters:

searchCriteria - The search criteria used to locate the entry to be modified

Returns:

The entry found, or null if no or multiple entries found

Throws:

java.lang.Exception - if an error occurs.

modEntry

public void modEntry(Entry newEntry,
                     SearchCriteria searchCriteria,
                     Entry oldEntry)
              throws MxConnectorException

Modifies an existing entry. The new entry data is given by the entry parameter and the search criteria specifies which entry to modify.

Specified by:

modEntry in interface ConnectorInterface

Overrides:

modEntry in class SimpleTpaeIFConnector

Parameters:

newEntry - The entry data

searchCriteria - The search criteria used to locate the entry to be modified

oldEntry - The old entry found by the search criteria

Throws:

MxConnectorException

deleteEntry

public void deleteEntry(Entry entry,
                        SearchCriteria sc)
                 throws MxConnectorException

Deletes an existing entry. The search criteria specifies which entry to modify. Some connectors may silently ignore the search criteria. For example, the LDAP connector will use the distinguished name ($dn) from the entry parameter (if it exists) rather than expanding the search criteria and search for the entry. Each connector's inner semantics governs whether the search parameter is used or not.

Specified by:

deleteEntry in interface ConnectorInterface

Overrides:

deleteEntry in class SimpleTpaeIFConnector

Parameters:

entry - The entry data

sc - The search criteria used to locate the entry to be deleted

Throws:

MxConnectorException

querySchema

public java.lang.Object querySchema(java.lang.Object obj)
                             throws java.lang.Exception

This method populates the input/output map of the connector with the hierarchical schema of the specified Object structure.

Note: This method uses SchemaUtils.convertEntryToSchemaHier(Entry, ConnectorConfig, boolean) method to display a hierarchical schema. However currently this method is no converting correctly the hierarchical entry to a hierarchical schema. This will be addressed later in the release.

Specified by:

querySchema in interface ConnectorInterface

Overrides:

querySchema in class SimpleTpaeIFConnector

Parameters:

obj - The object on which to discover schema. This may be an Entry or a string value

Returns:

A Vector of com.ibm.di.entry.Entry objects describing each entity

Throws:

java.lang.Exception - if an error while retrieving the schema occurs.

See Also:

Entry, Vector

getVersion

public java.lang.String getVersion()

Version information.

Specified by:

getVersion in interface VersionInfoInterface

Overrides:

getVersion in class SimpleTpaeIFConnector

Returns:

version information
