public class PECFrame
extends javax.swing.JInternalFrame
implements XMLChangeListener

The Policy Editor Component Frame, extends a JInternalFrame.

This is the Class that specifies the container of what is displayed in the PEComponent.

Each instantiation of a PECFrame would mean that a policy is instantiated.

Field Detail

PECFname

public java.lang.String PECFname

The Name that the JInternalFrame Displays in the top right corner.

It is usually also connected to the policies file name.

PECFPath

public java.lang.String PECFPath

Constructor Detail

PECFrame

public PECFrame(PEApplication PEA,
                java.lang.String newPolicyCaption)

Constructor for PECFrame. This loads a new JInternalFrame, as required by the super class, and sets some GUI properties that will be needed.

An initial size is set although the frame later on calls pack() to set itself to its best size. A minimum size is also set so that it does not get too squashed and leaves the minimum working area.

A new Policy Editor Component (PEComponent) is loaded on creating a PECFrame, and this frame is registered as its the PEComponents Frame.

Each PEComponent is registered as an XMLChangeListener to act when XMLChangeEvents are received.

Parameters:

PEA - a reference to the Policy Editor Application to be able to modify it as needed.

Method Detail

setPECFileName

public void setPECFileName(java.lang.String s)

Sets the PECF File name.

Parameters:

s - a String specifying the File Name to set the PECF to.

getPECFileName

public java.lang.String getPECFileName()

Gets the PECF File name.

Returns:

a String with the File Name.

setPECFPathName

public void setPECFPathName(java.lang.String s)

getPECFPathName

public java.lang.String getPECFPathName()

XMLChanged

public void XMLChanged(XMLChangeEvent ev)

When an XMLChangeEvent is received it will set the XMLEditor to the editor from which the request has come.

canUndo and canRedo, flags are updated, and the Frame is automatically set that it is not saved. Also the appropriate GUI for the PEApplication are set.

Specified by:

XMLChanged in interface XMLChangeListener

Parameters:

ev - The Event that just took place.

newOrOpen

public void newOrOpen(boolean choosePolicy,
                      java.lang.String types)

Gets the filename of a file from a FileDialog. The FileChooser Dialog, will have the .xml file filters that was declared in the PEApplication.

Checks if the file that was typed in exists or not when the user clicks ok. If it exists it will set the File Name for the PECFrame, and if it doesn't exist it will exit the dialog and inform the user that a valid filename needs to be entered.

Parameters:

choosePolicy - True to open an existing file

loadFromFile

public void loadFromFile(java.lang.String fname)
                  throws java.lang.Exception

Method that creates or loads a policy.

• if fname is empty it creates a new policy.
• Otherwise it loads the existing policy.

Parameters:

fname - the file name to open

Throws:

java.lang.Exception

extractPolicy

public java.lang.String extractPolicy(java.lang.String s)
                               throws java.lang.Exception

Extracts the policy from a signed File and Returns it as a string.

Throws:

java.lang.Exception

savePECF

public boolean savePECF(boolean show_dialog)

Performs the saving of the XML Policy.

Takes two values for it parameter, either true or false. When:

• True - It will display a dialog for a save as function.
• False - It will perform the save function.

Parameters:

show_dialog - boolean parameter for the correct action required from this method.
