Method Detail

applyDiffOnNodeState

public static SegmentNodeState applyDiffOnNodeState(FileStore fileStore,
                                                    @NotNull
                                                    @NotNull NodeState before,
                                                    @NotNull
                                                    @NotNull NodeState after,
                                                    @NotNull
                                                    @NotNull NodeState onto)
                                             throws IOException

Throws:

IOException

propertyAdded

public boolean propertyAdded(@NotNull
                             @NotNull PropertyState after)

Description copied from interface: NodeStateDiff

Called for all added properties.

Specified by:

propertyAdded in interface NodeStateDiff

Parameters:

after - property state after the change

Returns:

true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.

propertyChanged

public boolean propertyChanged(@NotNull
                               @NotNull PropertyState before,
                               @NotNull
                               @NotNull PropertyState after)

Description copied from interface: NodeStateDiff

Called for all changed properties. The names of the given two property states are guaranteed to be the same.

Specified by:

propertyChanged in interface NodeStateDiff

Parameters:

before - property state before the change

after - property state after the change

Returns:

true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.

propertyDeleted

public boolean propertyDeleted(PropertyState before)

Description copied from interface: NodeStateDiff

Called for all deleted properties.

Specified by:

propertyDeleted in interface NodeStateDiff

Parameters:

before - property state before the change

Returns:

true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.

childNodeAdded

public boolean childNodeAdded(@NotNull
                              @NotNull String name,
                              @NotNull
                              @NotNull NodeState after)

Description copied from interface: NodeStateDiff

Called for all added child nodes.

Specified by:

childNodeAdded in interface NodeStateDiff

Parameters:

name - name of the added child node

after - child node state after the change

Returns:

true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.

childNodeChanged

public boolean childNodeChanged(@NotNull
                                @NotNull String name,
                                @NotNull
                                @NotNull NodeState before,
                                @NotNull
                                @NotNull NodeState after)

Description copied from interface: NodeStateDiff

Called for all child nodes that may contain changes between the before and after states. The comparison implementation is expected to make an effort to avoid calling this method on child nodes under which nothing has changed.

Specified by:

childNodeChanged in interface NodeStateDiff

Parameters:

name - name of the changed child node

before - child node state before the change

after - child node state after the change

Returns:

true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.

childNodeDeleted

public boolean childNodeDeleted(String name,
                                NodeState before)

Description copied from interface: NodeStateDiff

Called for all deleted child nodes.

Specified by:

childNodeDeleted in interface NodeStateDiff

Parameters:

name - name of the deleted child node

before - child node state before the change

Returns:

true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
