public ScriptConnector()

Method Detail

initialize

public void initialize(Object obj)
                throws Exception

Description copied from class: Connector

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 Connector

Parameters:

obj - User provided parameter

Throws:

Exception

selectEntries

public void selectEntries()
                   throws Exception

Description copied from class: Connector

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 Connector

Throws:

Exception

getNextEntry

public Entry getNextEntry()
                   throws Exception

Description copied from class: Connector

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

Specified by:

getNextEntry in interface ConnectorInterface

Overrides:

getNextEntry in class Connector

Returns:

- the next Entry, or null if no more data

Throws:

Exception

See Also:

Connector.selectEntries()

modEntry

public void modEntry(Entry entry,
                     SearchCriteria search)
              throws Exception

Description copied from class: Connector

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 Connector

Parameters:

entry - The entry data

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

Throws:

Exception - Any exceptions thrown by the connector's underlying classes

modEntry

public void modEntry(Entry entry,
                     SearchCriteria search,
                     Entry old)
              throws Exception

Description copied from class: Connector

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 Connector

Parameters:

entry - The entry data

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

old - The old entry found by the search criteria

Throws:

Exception - Any exceptions thrown by the connector's underlying classes

deleteEntry

public void deleteEntry(Entry entry,
                        SearchCriteria search)
                 throws Exception

Description copied from class: Connector

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 wheter the search parameter is used or not.

Specified by:

deleteEntry in interface ConnectorInterface

Overrides:

deleteEntry in class Connector

Parameters:

entry - The entry data

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

Throws:

Exception - Any exceptions thrown by the connector's underlying classes

findEntry

public Entry findEntry(SearchCriteria search)
                throws Exception

Description copied from class: Connector

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

Specified by:

findEntry in interface ConnectorInterface

Overrides:

findEntry in class Connector

Parameters:

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

Returns:

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

Throws:

Exception - Any exceptions thrown by the connector's underlying classes

putEntry

public void putEntry(Entry entry)
              throws Exception

Description copied from class: Connector

Adds a new entry to the data source

Specified by:

putEntry in interface ConnectorInterface

Overrides:

putEntry in class Connector

Parameters:

entry - The entry data to add

Throws:

Exception - Any exceptions thrown by the connector's underlying classes

queryReply

public Entry queryReply(Entry entry)
                 throws Exception

Description copied from class: Connector

Performs a query/reply operations.

Specified by:

queryReply in interface ConnectorInterface

Overrides:

queryReply in class Connector

Parameters:

entry - The data used in outgoing call

Returns:

The entry returned by the peer

Throws:

Exception - Any exceptions thrown by the connector's underlying classes

terminate

public void terminate()
               throws Exception

Description copied from class: Connector

Terminate the connector. This function closes all connection and releases all resources used by the connector. This function also calls the parser's closeParser() method if a parser is active.

Specified by:

terminate in interface ConnectorInterface

Overrides:

terminate in class Connector

Throws:

Exception

querySchema

public Object querySchema(Object source)
                   throws Exception

Description copied from class: Connector

This function translates to whatever means a connector has to discover schema for a connection. The connector may implement this, in which case a Vector of Entry objects is returned for each column/attribute it discovered. For a database connector this would typically be column names and their attributes.

Each Entry in the Vector returned should contain the following attributes:

Name	Value
name	The name of the column/attribute/field ....
syntax	The syntax or expected value type
size	If specified this will give the user a hint as to how long the field may be

Specified by:

querySchema in interface ConnectorInterface

Overrides:

querySchema in class Connector

Parameters:

source - 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:

Exception

Entry, Vector

getVersion

public String getVersion()

Return version information

Specified by:

getVersion in interface VersionInfoInterface
