Constructor Detail

JCTreeData

public JCTreeData()

JCTreeData

public JCTreeData(int type)

JCTreeData

public JCTreeData(Applet applet,
                  String name)

Creates a JCTreeData which reads parameters from the applet's HTML file.

Parameters:

applet - the applet whose PARAM tags are to be read

name - if this is not null, only parameters preceded by this name are read

See Also:

Applet.getParameter(java.lang.String)

Method Detail

getName

public String getName()

Gets the name of the Bean, as set in the constructor or by setName. If no name has been set, a 0-length String will be returned.

Returns:

See Also:

setName(java.lang.String)

setName

public void setName(String name)

Sets the name of the Bean.

Parameters:

name - Bean name

getParameters

public void getParameters(Applet applet)

Reads the parameter values from the HTML page using the specified applet. The values will override those previously set.

Parameters:

applet -

See Also:

Applet.getParameter(java.lang.String)

getParameters

public void getParameters(Applet applet,
                          String file)

Reads the parameter values from the file. The values will override those previously set.

Parameters:

applet - if not null and in a browser, its documentBase() is used to construct a complete filename if necessary

file - if an http protocol is not specified (if a ":" is not present), the current working directory is used

getAppletContext

public AppletContext getAppletContext()

Gets the Bean's applet's context. The applet context lets an applet control the applet's environment, which is usually the browser or the applet viewer.

Returns:

null if the component is not in an applet or the applet is not in a browser

See Also:

Applet.getAppletContext()

getAppletContext

public static AppletContext getAppletContext(Applet applet)

Gets the Bean's applet's context. The applet context lets an applet control the applet's environment, which is usually the browser or the applet viewer.

Parameters:

applet -

Returns:

null if the component is not in an applet or the applet is not in a browser.

See Also:

Applet.getAppletContext()

getAbout

public String getAbout()

Gets the about property. The about property displays contact information for Quest Software.

Returns:

the about propety

setAbout

public void setAbout(String s)

about property is read-only.

Parameters:

s -

getVersion

public String getVersion()

Gets the value of the Version property. The Version property specifies the JClass version number.

Returns:

setVersion

public void setVersion(String s)

Version property is read-only.

Parameters:

s -

setModelName

public void setModelName(String s)

Sets the model name of the tree data Bean.

Specified by:

setModelName in interface DataModel

Overrides:

setModelName in class TreeData

Parameters:

s -

setTreeProperties

public void setTreeProperties(com.klg.jclass.datasource.beans.TreeProperties comp)
                       throws DataModelException

Sets TreeProperties property.

Parameters:

comp -

Throws:

DataModelException - If fails to create a meta data.

getTreeProperties

public com.klg.jclass.datasource.beans.TreeProperties getTreeProperties()

Gets TreeProperties property.

Returns:

See Also:

setTreeProperties(com.klg.jclass.datasource.beans.TreeProperties)

setTreeProperties

public void setTreeProperties(String resource_name,
                              ClassLoader cl)
                       throws DataModelException

Sets the tree data Bean component using a serialization file.

Parameters:

resource_name - resource name relative to a class loader to the tree data Bean component

cl - class loader used to get the resource

Throws:

DataModelException - If fails to create a meta data.

addDataModelListener

public void addDataModelListener(com.klg.jclass.datasource.DataModelListener listener)

implements DataModel method addDataModelListener.

Specified by:

addDataModelListener in interface DataModel

Overrides:

addDataModelListener in class TreeData

Parameters:

listener -

See Also:

DataModelListener

createMetaData

protected void createMetaData()
                       throws DataModelException

Creates meta data for the tree data Bean.

Throws:

DataModelException - If fails to create a meta data.

getParameters

protected void getParameters()

Reads the parameter values from the HTML page using the tree data Bean's applet. The values will override those previously set. Subclasses may override this method to set their own values; in this case, the method should first call super.getParameters().
