Method Detail

isStateful

public boolean isStateful()

Description copied from class: DoCommand

Return true if this changes the state and false if it instead encodes a change. If isStateful() returns true, then change(State) has some effect. If isStateful() returns false, invert() must work.

Overrides:

isStateful in class DoCommand

Returns:

equals

public boolean equals(Object obj)

Overrides:

equals in class DoCommand

getParameters

public Map<String,Object> getParameters()

Specified by:

getParameters in interface ParameterChange

hashCode

public int hashCode()

Overrides:

hashCode in class DoCommand

toString

public String toString()

Overrides:

toString in class DoCommand

invert

public DoCommand invert()
                 throws UnsupportedOperationException

Description copied from class: DoCommand

invert this command. applying a DoCommand followed by its inverse will result in no net change.
If isStateful() returns true, then this will throw an UnsupportedOperationException and if isStateful() is false, this cannot throw an UnsupportedOperationException.

Overrides:

invert in class DoCommand

Returns:

the inverse of this command. By Default return this

Throws:

UnsupportedOperationException - if isStateful()

getOldParameters

public Map<String,Object> getOldParameters()

Specified by:

getOldParameters in interface ParameterChange

coalesce

public BulkParameterEvent coalesce(Undoable laterEvt)

Description copied from class: DoCommand

Coalesce these commands if we can. Any result other than null renders this event unusable.

Specified by:

coalesce in interface Undoable

Overrides:

coalesce in class DoCommand

Parameters:

laterEvt - the later event

Returns:

an event if we can coalesce, null if we can't.
