All Known Implementing Classes:

AbstractContributedRulerColumn

---

public interface IContributedRulerColumn
extends 
IVerticalRulerColumn

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 Detail

getDescriptor

RulerColumnDescriptor getDescriptor()

Returns the extension point descriptor of this ruler.

Returns:

descriptor the extension point descriptor of this ruler or null if called before columnCreated()

---

setDescriptor

void setDescriptor(
RulerColumnDescriptor descriptor)

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)

Sets the editor (called right after the extension was instantiated).

This method will be called by the framework and must not be called by clients.

Parameters:

editor - the editor targeted by this ruler instance

---

getEditor

ITextEditor getEditor()

Returns the editor targeted by this ruler instance.

Returns:

the editor targeted by this ruler instance or null if called before columnCreated()

---

columnCreated

void columnCreated()

Hook method called after a column has been instantiated, but before it is added to a CompositeRuler and before createControl 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()

Hook method called after a column has been removed from the 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.
