Class AgentClient

java.lang.Object

      edu.sdsc.inca.Client
          edu.sdsc.inca.AgentClient

public class AgentClient
extends Client

This class allows access to the services provided by an Inca Agent. Along with defining an API that understands the Agent protocol, it defines a main method that allows access to an Agent via a telnet-style interface and provides a means for configuring an Inca installation from the command line.

Method Detail

getCatalog

public java.util.Properties[] getCatalog(java.lang.String url)
                                  throws java.io.IOException,
                                         ProtocolException

Returns properties for all reporters contained within one repository or all repositories known to the Agent.

Parameters:

url - the url of the repository to query; if null, a merged catalog from all repositories known to the Agent is returned

Returns:

an array of Properties, each of which represents the attributes of a single repository package

Throws:

java.io.IOException - on read/write error

ProtocolException - on an invalid message

getCatalogAsXml

public java.lang.String getCatalogAsXml(java.lang.String uri)
                                 throws java.io.IOException,
                                        ProtocolException

Like getCatlog, but returns wraps the catalog information into XML instead of an array of Properties. The outer tag of the XML is <catalog>, which returns 0 or more <reporter> subtags. Each of these contains zero or more <property> subtags, which list the property name and value in subtags.

Parameters:

url - the url of the repository to query; if null, a merged catalog from all repositories known to the Agent is returned

Returns:

XML, described above, that gives the contents of the repository

Throws:

java.io.IOException - on read/write error

ProtocolException - on an invalid message

getConfig

public java.lang.String getConfig()
                           throws java.io.IOException,
                                  ProtocolException

Returns IncaDocument XML for the Inca deployment configuration.

Returns:

IncaDocument XML for the deployment configuration

Throws:

java.io.IOException - on read/write error

ProtocolException - on an invalid message

getDeployPath

public java.lang.String getDeployPath()

Returns the path to the IncaDocument XML deployment file.

Returns:

the path to the deployment file

setConfig

public void setConfig(java.lang.String config)
               throws java.io.IOException,
                      ProtocolException

Replaces or updates the Inca deployment configuration.

Parameters:

config - IncaDocument XML specifying changes in the configuration

Throws:

java.io.IOException - on read/write error

ProtocolException - on an invalid message

setConfiguration

public void setConfiguration(java.util.Properties config)
                      throws ConfigurationException

A convenience function for setting multiple configuration properties at once. In addition to the keys recognized by the superclass, recognizes: "agent", the specification of the Agent; "file", a path to an IncaDocument XML file.

Overrides:

setConfiguration in class Client

Parameters:

config - contains AgentClient configuration values

Throws:

ConfigurationException - on a faulty configuration property value

setDeployPath

public void setDeployPath(java.lang.String path)

Sets the path to the IncaDocument XML deployment file.

Parameters:

path - the path to the deployment file

main

public static void main(java.lang.String[] args)

A simple main method for exercising the AgentClient.

 usage: java inca.AgentClient

  -a|--auth     boolean Authenticated (secure) connection?
  -A|--agent    str     Agent specification; host:port
  -c|--cert     path    Path to the authentication certificate
  -f|--file     path    Inca installation configuration file path
  -h|--help     null    Print help/usage
  -i|--init     path    Path to properties file
  -k|--key      path    Path to the authentication key
  -P|--password str     Specify how to obtain encryption password
  -t|--trusted  path    Path to authentication trusted certificate dir
  -V|--version  null    Display program version
 

Each of these properties, other than --init, can also be specified in the initialization file or in system properties defined via the -D switch. In each of these cases, the configuration name must be prefixed with "inca.agent.", e.g., use "inca.agent.cert" to specify the cert value. Command line arguments override any properties specified in this fashion. If --file is specified, the main method reads the specified file and sends it to the Agent in a setConfig message; otherwise, main allows the user to communicate with the Agent via a telnet-style interface. Supported values for the --password argument are: "no" or "false" (no encryption); "yes", "true", or "stdin:prompt" (read password from stdin after optionally prompting); "pass:text" (specify the password directly--should only be used for testing and, possibly, in the init file).

Parameters:

args - command line arguments, as above.
