Class IltSystem

java.lang.Object

ilog.cpl.IlpSystem

ilog.tgo.IltSystem

public class IltSystem
extends IlpSystem

This class is used to initialize a JTGO application or applet. It inherits almost all its functionality from IlpSystem. The following differences exist:

• it creates an instance of IltDefaultContext instead of IlpDefaultContext, if jviews-tgo.jar or jviews-tgo-all.jar are found on the classpath.

Since:

JTGO 3.0

Field Detail

StyleCompatibilityMode

public static boolean StyleCompatibilityMode

Indicates that compatibility with previous style customization shall be used.

This flag is used for the following scenarios:

• Style property IlpObject.PositionFixed: instead of using this style key, use CSS property fixed as a per-object parameter in the configuration of the link or node graph layout renderers (See IlpGraphLayoutParameters.isFixed())

Since:

JViews 7.5

Method Detail

BeanInit

public static final void BeanInit(Object theCreatedBean,
                                  boolean verbose)

This method should be called in the constructor of any JavaBean that uses JTGO. This method should be the first instruction after the call to any constructor of the superclass.

Init

public static void Init()

Initializes a JTGO process and creates a default context using a deployment descriptor.

The system looks for the deployment descriptor as follows:

• a file name obtained from the ilog.cpl.deploymentDescriptorName property
• a file called cpldeploy.xml

The file is looked for:

• in the current directory,
• in the user's home directory on Windows, in a subdirectory $HOME/.cpl/ of the user's home directory on Unix,
• on the classpath.

To use a custom deployment descriptor you could also use one of the versions of this method that takes a deployment descriptor name as a parameter.

If no custom deployment descriptor is found, a default one of type IlpDefaultContext is created.

This method should not be used to initialize an applet. Use the versions of Init that take an Applet parameter or an absolute URL instead.

If this method is called more than once the initialization is performed only once.

Init

public static void Init(String deploymentDescriptorName)
                 throws FileNotFoundException,
                        IOException,
                        IlpDeploymentParsingException

Initializes a JTGO process and creates a default context using a deployment descriptor specified by a file name.

The deployment descriptor name provided may be an absolute path, or relative to the current directory for the application. Under Windows, the drive letter in an absolute path is considered as the type of the file; to avoid confusion, you must specify "file:" at the very beginning of the path.

This method should not be used to initialize an applet. Use the versions of Init that take an Applet parameter or an absolute URL instead.

Parameters:

deploymentDescriptorName - absolute or relative file name

Throws:

FileNotFoundException

IOException

IlpDeploymentParsingException

Init

public static void Init(URL documentBase,
                        String deploymentDescriptorName)
                 throws FileNotFoundException,
                        IOException,
                        IlpDeploymentParsingException

Initializes the system using a deployment descriptor specified by a relative URL, relative to a given base URL.

Throws:

FileNotFoundException

IOException

IlpDeploymentParsingException

Internal: do not use!

Init

public static void Init(URL deploymentDescriptorURL,
                        URL defaultDocumentBase)
                 throws FileNotFoundException,
                        IOException,
                        IlpDeploymentParsingException

Initializes the system using a deployment descriptor specified by an URL.

This method may be used to initialize either an application or an applet.

Parameters:

deploymentDescriptorURL - URL of deployment descriptor

defaultDocumentBase - Default document base URL

Throws:

FileNotFoundException

IOException

IlpDeploymentParsingException

Internal: do not use!

Init

public static void Init(Applet applet)

Deprecated. since 9.0 : Applet will be deprecated with JDK 9

Initializes a CPL applet and creates a default context using a default deployment descriptor.

The document base of the applet is used as the document base for the default URL access service created.

The default deployment descriptor is obtained from the CPL jar. To use a custom deployment descriptor, use one of the versions of this method that takes a deployment descriptor name as a parameter.

Init

public static void Init(Applet applet,
                        String deploymentDescriptorName)
                 throws FileNotFoundException,
                        IOException,
                        IlpDeploymentParsingException

Deprecated. since 9.0 : Applet will be deprecated with JDK 9

Initializes a CPL applet and creates a default context using a deployment descriptor specified by a relative file name. Under Windows, the drive letter in a path is considered as the type of the file; to avoid confusion, you must specify "file:" at the very beginning of the path.

The document base of the applet is used as the document base for the default URL access service.

Throws:

FileNotFoundException

IOException

IlpDeploymentParsingException

Init

public static void Init(IlpContext defaultContext)

Initializes the system based on a service context.

The user should ensure that the context is properly configured for subsequent use.

Parameters:

defaultContext - The default service context used in the application
