Constructor Details

MapBoundsEvent

public MapBoundsEvent(MapContent source,
 int type,
 ReferencedEnvelope oldAreaOfInterest,
 ReferencedEnvelope newAreaOfInterest)

Creates a new instance of BoundsEvent

Parameters:

source - the map context reporting the change

type - the type of change indicated by one or both of the bit masks AREA_OF_INTEREST_MASK and COORDINATE_SYSTEM_MASK

oldAreaOfInterest - the context's previous area of interest

newAreaOfInterest - the context's new area of interest

Throws:

IllegalArgumentException - if type is invalid

MapBoundsEvent

public MapBoundsEvent(MapViewport source,
 MapBoundsEvent.Type type,
 ReferencedEnvelope oldBounds,
 ReferencedEnvelope newBounds)

Creates a new instance of BoundsEvent.

Example:

 new MapBoundsEvent(map, EnumSet.of(Type.BOUNDS), null, bounds)
 

Parameters:

source - map viewport reporting the change

type - Type of event indicating MapBoundsEvent.Type.BOUNDS or MapBoundsEvent.Type.CRS

oldBounds - the context's previous area of interest

newBounds - the context's new area of interest

Throws:

IllegalArgumentException - if type is invalid

MapBoundsEvent

public MapBoundsEvent(MapViewport source,
 EnumSet<MapBoundsEvent.Type> type,
 ReferencedEnvelope oldBounds,
 ReferencedEnvelope newBounds)

Creates a new instance of BoundsEvent.

Example:

 new MapBoundsEvent(map, EnumSet.of(Type.BOUNDS), null, bounds)
 

Parameters:

source - map viewport reporting the change

type - EnumSet flagging one or both of the following AREA_OF_INTEREST_MASK and COORDINATE_SYSTEM_MASK

oldBounds - the context's previous area of interest

newBounds - the context's new area of interest

Throws:

IllegalArgumentException - if type is invalid

Method Details

getType

public int getType()

Getter for property type. The type is a bitwise or of the masks defined above.

Returns:

Value of property type.

getEventType

public EnumSet<MapBoundsEvent.Type> getEventType()

Set of event types raised for this event.

getOldCoordinateReferenceSystem

public CoordinateReferenceSystem getOldCoordinateReferenceSystem()

Get the previous coordinate reference system. This is a convenience method equivalent to getOldAreaOfInterest().getCoordinateReferenceSystem()

Returns:

the previous CoordinateReferenceSystem object

getNewCoordinateReferenceSystem

public CoordinateReferenceSystem getNewCoordinateReferenceSystem()

Get the new coordinate reference system. This is a convenience method equivalent to getNewAreaOfInterest().getCoordinateReferenceSystem()

Returns:

the new CoordinateReferenceSystem object

getOldAreaOfInterest

public ReferencedEnvelope getOldAreaOfInterest()

Get the old area of interest

getNewAreaOfInterest

public ReferencedEnvelope getNewAreaOfInterest()

Get the new area of interest
