org.eclipse.ui.texteditor.rulers .IContributedRulerColumn

All known Subclasses:   org.eclipse.ui.texteditor.rulers .AbstractContributedRulerColumn,
IContributedRulerColumn
public interface IContributedRulerColumn extends IVerticalRulerColumn(Code)
Interface that has to be implemented by contributions to the org.eclipse.ui.texteditor.rulerColumns extension point.
Implementors must have a zero-argument constructor so that they can be created by IConfigurationElement.createExecutableExtension(String) .

since:
   3.3

Method Summary
void columnCreated()
     Hook method called after a column has been instantiated, but before it is added to a org.eclipse.jface.text.source.CompositeRuler and before is called.
void columnRemoved()
     Hook method called after a column has been removed from the org.eclipse.jface.text.source.CompositeRuler .
This happens when

the column is hidden by the user or programmatically

the editor is closed

the editor input changes and the column no longer targets the editor contents.

The column will not be used after this method has been called.
RulerColumnDescriptor getDescriptor()
     Returns the extension point descriptor of this ruler.
ITextEditor getEditor()
     Returns the editor targeted by this ruler instance.
void setDescriptor(RulerColumnDescriptor descriptor)
     Sets the extension point descriptor of this ruler.
void setEditor(ITextEditor editor)
     Sets the editor (called right after the extension was instantiated).

Method Detail
columnCreated
void columnCreated()(Code)
Hook method called after a column has been instantiated, but before it is added to a org.eclipse.jface.text.source.CompositeRuler and before is called.
This happens when

the column is set visible by the user or programmatically

the editor is created, if this ruler targets the editor and is enabled by default

the editor input changes and the column now targets the new editor contents.

columnRemoved
void columnRemoved()(Code)
Hook method called after a column has been removed from the org.eclipse.jface.text.source.CompositeRuler .
This happens when

the column is hidden by the user or programmatically

the editor is closed

the editor input changes and the column no longer targets the editor contents.

The column will not be used after this method has been called. A new column will be instantiated if the same column type should be shown for the same editor.

getDescriptor
RulerColumnDescriptor getDescriptor()(Code)
Returns the extension point descriptor of this ruler. descriptor the extension point descriptor of this ruler or null if called before IContributedRulerColumn.columnCreated()

getEditor
ITextEditor getEditor()(Code)
Returns the editor targeted by this ruler instance. the editor targeted by this ruler instance or null if called before IContributedRulerColumn.columnCreated()

setDescriptor
void setDescriptor(RulerColumnDescriptor descriptor)(Code)
Sets the extension point descriptor of this ruler.
This method will be called by the framework and must not be called by clients.

Parameters:
  descriptor - the extension point descriptor

setEditor
void setEditor(ITextEditor editor)(Code)
Sets the editor (called right after the extension was instantiated).
