Constructor Detail

FileStoreEditorInput

public FileStoreEditorInput(
IFileStore fileStore)
Parameters:
fileStore -
Method Detail

exists

public boolean exists()
Description copied from interface: IEditorInput
Returns whether the editor input exists.

This method is primarily used to determine if an editor input should appear in the "File Most Recently Used" menu. An editor input will appear in the list until the return value of exists becomes false or it drops off the bottom of the list.

Specified by:
exists in interface IEditorInput
Returns:
true if the editor input exists; false otherwise

getImageDescriptor

public 
ImageDescriptor getImageDescriptor()
Description copied from interface: IEditorInput
Returns the image descriptor for this input.

Note: although a null return value has never been permitted from this method, there are many known buggy implementations that return null. Clients that need the image for an editor are advised to use IWorkbenchPart.getImage() instead of IEditorInput.getImageDescriptor(), or to recover from a null return value in a manner that records the ID of the problematic editor input. Implementors that have been returning null from this method should pick some other default return value (such as ImageDescriptor.getMissingImageDescriptor()).

Specified by:
getImageDescriptor in interface IEditorInput
Returns:
the image descriptor for this input; may be null if there is no image.

getName

public 
String getName()
Description copied from interface: IEditorInput
Returns the name of this editor input for display purposes.

For instance, when the input is from a file, the return value would ordinarily be just the file name.

Specified by:
getName in interface IEditorInput
Returns:
the name string; never null;

getPersistable

public 
IPersistableElement getPersistable()
Description copied from interface: IEditorInput
Returns an object that can be used to save the state of this editor input.

Specified by:
getPersistable in interface IEditorInput
Returns:
the persistable element, or null if this editor input cannot be persisted

getToolTipText

public 
String getToolTipText()
Description copied from interface: IEditorInput
Returns the tool tip text for this editor input. This text is used to differentiate between two input with the same name. For instance, MyClass.java in folder X and MyClass.java in folder Y. The format of the text varies between input types.

Specified by:
getToolTipText in interface IEditorInput
Returns:
the tool tip text; never null.

getAdapter

public 
Object getAdapter(
Class adapter)
Description copied from interface: IAdaptable
Returns an object which is an instance of the given class associated with this object. Returns null if no such object can be found.

Specified by:
getAdapter in interface IAdaptable
Parameters:
adapter - the adapter class to look up
Returns:
a object castable to the given class, or null if this object does not have an adapter for the given class

equals

public boolean equals(
Object o)
Overrides:
equals in class Object

hashCode

public int hashCode()
Overrides:
hashCode in class Object

getURI

public 
URI getURI()
Description copied from interface: IURIEditorInput
Returns the URI of the file underlying this editor input.

Specified by:
getURI in interface IURIEditorInput
Returns:
URI

getFactoryId

public 
String getFactoryId()
Description copied from interface: IPersistableElement
Returns the id of the element factory which should be used to re-create this object.

Factory ids are declared in extensions to the standard extension point "org.eclipse.ui.elementFactories".

Specified by:
getFactoryId in interface IPersistableElement
Returns:
the element factory id
See Also:
IElementFactory

saveState

public void saveState(
IMemento memento)
Description copied from interface: IPersistable
Saves the state of the object in the given memento.

Specified by:
saveState in interface IPersistable
Parameters:
memento - the storage area for object's state
