Interface IResourceDiff

All Superinterfaces:

IDiff, ITwoWayDiff

All Known Implementing Classes:

ResourceDiff

public interface IResourceDiff
extends ITwoWayDiff

A resource diff represents the changes between two resources. The diff can be used to describe the change between an ancestor and remote, an ancestor and local or between the local and a remote for two-way comparisons.

Since:

3.2

Restriction:

This interface is not intended to be implemented by clients. Clients that need to create deltas should instead use or subclass ResourceDiff

Methods

Modifier and Type	Method and Description
IFileRevision	getAfterState() Return a handle to the file state representing the "after" state of the file used to calculate this diff.

Field Detail

OPEN

static final int OPEN

Change constant (bit mask) indicating that the resource was opened or closed. For example, if the current state of the resource is open then it was previously closed.

DESCRIPTION

static final int DESCRIPTION

Change constant (bit mask) indicating that a project's description has changed.

Method Detail

getResource

IResource getResource()

Return the local resource to which this diff applies.

Returns:

the local resource to which this diff applies

getBeforeState

IFileRevision getBeforeState()

Return a handle to the file state representing the "before" state of the file used to calculate this diff. A null is returned if the resource is not a file or if the file does not exist in the before state. If a file state is returned, clients should still check the IFileState.exists() method to see if the file existed in the before state.

Returns:

a handle to the file state representing the "before" state used to calculate this diff

getAfterState

IFileRevision getAfterState()

Return a handle to the file state representing the "after" state of the file used to calculate this diff. A null is returned if the resource is not a file or if the file does not exist in the after state. If a file state is returned, clients should still check the IFileState.exists() method to see if the file existed in the after state.

Returns:

a handle to the file state representing the "before" state used to calculate this diff
