Method Detail

getLogger

public org.apache.log4j.Logger getLogger()

Returns:

the logger

nodeAdded

public void nodeAdded(javax.swing.tree.TreeNode treeNode)

Description copied from interface: TreeNodeChangeListener

The TreeNode passed to this method has just been added to the a containing element.

Specified by:

nodeAdded in interface TreeNodeChangeListener

Parameters:

treeNode - This element is now part of the SBMLDocument.

nodeRemoved

public void nodeRemoved(TreeNodeRemovedEvent evt)

Description copied from interface: TreeNodeChangeListener

The TreeNodeRemovedEvent passed to this method provides information about the node that has been removed from a containing parent and does hence no longer belong to the SBMLDocument anymore. In addition, a pointer to its previous parent is also provided. In this way, an implementing class can identify the location within the tree where it was before.

Specified by:

nodeRemoved in interface TreeNodeChangeListener

Parameters:

evt - The event containing information about the removed TreeNode.

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

saveToString

private java.lang.String saveToString(java.lang.Object object)

Tries to call the Object.toString() method on the given object. If the argument is null, it returns "null". In case that the call of Object.toString() fails, the simple class name of the object is returned.

Parameters:

object - the java Object to write as a String

Returns:

some String representation of the given object.

toString

public java.lang.String toString(java.beans.PropertyChangeEvent evt)
