Constructor Summary

ResourceDiff(IResource resource, int kind)
Convenience constructor for creating a simple folder diff that consists of a resource and a kind only.

ResourceDiff(IResource resource, int kind, int flags, IFileRevision before, IFileRevision after)
Create a two-way resource diff

Method Summary

IFileRevision	getAfterState() Return a handle to the file state representing the "after" state of the file used to calculate this diff.
IFileRevision	getBeforeState() Return a handle to the file state representing the "before" state of the file used to calculate this diff.
IResource	getResource() Return the local resource to which this diff applies.

Constructor Detail

ResourceDiff

public ResourceDiff(IResource resource,
                    int kind,
                    int flags,
                    IFileRevision before,
                    IFileRevision after)

Create a two-way resource diff

Parameters:

resource - the resource

kind - the kind of change (ADDED, REMOVED or CHANGED)

flags - additional flags that describe the change

before - the before state of the model object

after - the after state of the model object

ResourceDiff

public ResourceDiff(IResource resource,
                    int kind)

Convenience constructor for creating a simple folder diff that consists of a resource and a kind only. It is equivalent to ResourceDiff(resource, kind, 0, null, null)

Parameters:

resource - a resource

kind - the kind of change (ADDED, REMOVED or CHANGED)

Method Detail

getBeforeState

public IFileRevision getBeforeState()

Description copied from interface: IResourceDiff

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.

Specified by:

getBeforeState in interface IResourceDiff

Returns:

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

getAfterState

public IFileRevision getAfterState()

Description copied from interface: IResourceDiff

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.

Specified by:

getAfterState in interface IResourceDiff

Returns:

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

getResource

public IResource getResource()

Description copied from interface: IResourceDiff

Return the local resource to which this diff applies.

Specified by:

getResource in interface IResourceDiff

Returns:

the local resource to which this diff applies
