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

equals

public boolean equals(Object obj)

Overrides:

equals in class TwoWayDiff
