Constructor Detail

MoveBranchRequest

public MoveBranchRequest(Location from,
                         Location into)

Create a request to move a branch from one location into another.

Parameters:

from - the location of the top node in the existing branch that is to be moved

into - the location of the existing node into which the branch should be moved

Throws:

IllegalArgumentException - if from or into are null

MoveBranchRequest

public MoveBranchRequest(Location from,
                         Location into,
                         NodeConflictBehavior conflictBehavior)

Create a request to move a branch from one location into another.

Parameters:

from - the location of the top node in the existing branch that is to be moved

into - the location of the existing node into which the branch should be moved

conflictBehavior - the expected behavior if an equivalently-named child already exists at the into location

Throws:

IllegalArgumentException - if any of the parameters are null

Method Detail

from

public Location from()

Get the location defining the top of the branch to be moved

Returns:

the from location; never null

into

public Location into()

Get the location defining the parent where the branch is to be placed

Returns:

the to location; never null

conflictBehavior

public NodeConflictBehavior conflictBehavior()

Get the expected behavior when copying the branch and the destination already has a node with the same name.

Returns:

the behavior specification

isReadOnly

public boolean isReadOnly()

Return whether this request only reads information.

Specified by:

isReadOnly in class Request

Returns:

true if this request reads information, or false if it requests that the repository content be changed in some way

See Also:

Request.isReadOnly()

setActualLocations

public void setActualLocations(Location oldLocation,
                               Location newLocation)

Sets the actual and complete location of the node being renamed and its new location. This method must be called when processing the request, and the actual location must have a path.

Parameters:

oldLocation - the actual location of the node before being renamed

newLocation - the actual location of the node after being renamed

Throws:

IllegalArgumentException - if the either location is null, if the old location does not represent the same location as the from location, if the new location does not represent the same location as the into location, or if the either location does not have a path

getActualLocationBefore

public Location getActualLocationBefore()

Get the actual location of the node before being moved.

Returns:

the actual location of the node before being moved, or null if the actual location was not set

getActualLocationAfter

public Location getActualLocationAfter()

Get the actual location of the node after being moved.

Returns:

the actual location of the node after being moved, or null if the actual location was not set

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:
