Method Detail

selectEntries

public void selectEntries()
                   throws Exception

default implementation

Specified by:

selectEntries in interface ConnectorInterface

Overrides:

selectEntries in class Connector

Throws:

Exception - never

terminate

public void terminate()

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

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.

getNextEntry

public Entry getNextEntry()
                   throws Exception

Returns the next Entry from the connector. If we are in Server mode, accept a new Connection. If there is a Parser connected to this Connector, the Parser is used to read the next Entry. The Entry will have three special Properties:

• socket - The socket we are reading from
• inp - a BufferedReader using the socket
• out - a BufferedWriter using the socket

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

See Also:

selectEntries()

putEntry

public void putEntry(Entry entry)
              throws Exception

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 Connector

Parameters:

entry - The entry data to add

Throws:

Exception - if an error occurs.

getReader

public Reader getReader()
                 throws Exception

Returns a reader object for the socket

Returns:

the input reader

Throws:

Exception - if an error occurs

getWriter

public Writer getWriter()
                 throws Exception

Returns a writer object for the socket

Returns:

the output writer

Throws:

Exception - if an error occurs

getSocket

public Socket getSocket()

Returns the Socket we are reading from or writing to

Returns:

the Socket we are reading from or writing to

getCertificates

public Certificate[] getCertificates()
                              throws SSLPeerUnverifiedException

Returns the Certificates of the peer. If this is not an SSL Session, return null, otherwise return the same as

 getSocket().getSession().getPeerCertificates();
 

Returns:

an ordered array of peer certificates, with the peer's own certificate first followed by any certificate authorities.

Throws:

SSLPeerUnverifiedException - if the peer's identity has not been verified

getVersion

public String getVersion()

Return version information

Specified by:

getVersion in interface VersionInfoInterface

Returns:

version info
