Class constructor

Method Detail

selectEntries

public void selectEntries()
                   throws Exception

Default implementation

Specified by:

selectEntries in interface ConnectorInterface

Overrides:

selectEntries in class Connector

Throws:

Exception - never

initialize

public void initialize(Object o)
                throws 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 Connector

Parameters:

o - User provided parameter

Throws:

Exception - if the initialization of this connector fails.

setNextEntry

public void setNextEntry(Entry e)

Sets next entry for server mode

Parameters:

e - next clien

getNextEntry

public Entry getNextEntry()
                   throws Exception

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 Connector

Returns:

- the next Entry, or null if no more data

Throws:

Exception - if an error occurs.

ConnectorInterface.selectEntries()

getNextClient

public ConnectorInterface getNextClient()
                                 throws Exception

Server mode - return a clone of self that handles the next client instance when running in server mode. The returned connector may be used in its own thread to handle a "client" request so if the returned instance is returned more than once it must be thread safe.

Specified by:

getNextClient in interface ConnectorInterface

Overrides:

getNextClient in class Connector

Returns:

the clone of itself

Throws:

Exception - if an error occurs.

checkDay

public void checkDay(String month,
                     int dateNum,
                     String[] checkTime)
              throws Exception

Checks if the specified day options are correct

Parameters:

month - month name

dateNum - date number

checkTime - time

Throws:

Exception - if the day is not valid

checkDate

public void checkDate(String[] checkTime,
                      int dateNum,
                      int whichDate)
               throws Exception

Checks if the date specified is correct

Parameters:

checkTime - time

dateNum - month number

whichDate - date number

Throws:

Exception - if an error occurs

validSchedule

public void validSchedule(String[] checkTime)
                   throws Exception

Verifies the the schedule is correct

Parameters:

checkTime - time to be checked

Throws:

Exception - if a problem occurs

calcNextRun

public void calcNextRun()
                 throws Exception

Calculates the next run

Throws:

Exception - if schedule is invalid or missing

doWait

public void doWait(long p1,
                   long p2)
            throws InterruptedException

Connector waits for the specified difference in the parameters

Parameters:

p1 - wait until

p2 - current time in milliseconds

Throws:

InterruptedException - if the connector is interrupted

sleepSeconds

public boolean sleepSeconds(long p1)

This function is not used directly, but maybe some old configurations use this.Connector sleeps for the specified time

Parameters:

p1 - time to wait

Returns:

is connector sleeping

getMaskSchedule

public String getMaskSchedule()

Retrieves the schedule to next run

Returns:
