LuciadFusionClass TLspPaintedObjectsBoundsQuery

com.luciad.view.lightspeed.query.ALspPaintQuery<Collection<ALspBoundsInfo>>

com.luciad.view.lightspeed.query.TLspPaintedObjectsBoundsQuery

public class TLspPaintedObjectsBoundsQuery
extends ALspPaintQuery<Collection<ALspBoundsInfo>>

Query to retrieve the bounds of all objects that are painted and overlap with a specified view region.

This query only takes the objects that are currently painted into account.

The bounds(com.luciad.view.lightspeed.layer.ALspWorldBoundsInfo) methods may be called multiple times for the same object if it has multiple bounds. This implementation collects all bounds.

Since:

2012.0

Constructor Detail

TLspPaintedObjectsBoundsQuery

public TLspPaintedObjectsBoundsQuery(TLspPaintRepresentationState aPaintRepresentationState,
                                     ILcdPoint aViewPoint,
                                     double aSensitivity)

Creates a new objects bounds query.

Parameters:

aPaintRepresentationState - the paint representation state

aViewPoint - the view point

aSensitivity - the sensitivity

TLspPaintedObjectsBoundsQuery

public TLspPaintedObjectsBoundsQuery(TLspPaintRepresentationState aPaintRepresentationState,
                                     ILcdBounds aViewBounds,
                                     double aSensitivity)

Creates a new objects bounds query.

Parameters:

aPaintRepresentationState - the paint representation state

aViewBounds - the view bounds or null if unrestricted

aSensitivity - the sensitivity

Method Detail

getPaintRepresentationState

public TLspPaintRepresentationState getPaintRepresentationState()

Returns the paint representation state that should be queried.

Returns:

the paint representation state

getViewBounds

public ILcdBounds getViewBounds()

Returns the view bounds that should be queried or null if unrestricted.

Returns:

the view bounds or null

getSensitivity

public double getSensitivity()

Returns the sensitivity in pixels.

Returns:

the sensitivity

getResult

public Collection<ALspBoundsInfo> getResult()

Returns the bounds infos of all objects.

Specified by:

getResult in class ALspPaintQuery<Collection<ALspBoundsInfo>>

Returns:

the bounds infos, never null.

bounds

public boolean bounds(ALspWorldBoundsInfo aBoundsInfo)

Called for all objects with world bounds.

Note that the aBoundsInfo may change after this method call returns. The implementation can create a ALspBoundsInfo.clone() if it still needs it after the method call returns.

Parameters:

aBoundsInfo - the bounds info

Returns:

true if the query should continue, false if it should stop

bounds

public boolean bounds(ALspViewBoundsInfo aBoundsInfo)

Called for all objects with view bounds.

Note that the aBoundsInfo may change after this method call returns. The implementation can create a ALspBoundsInfo.clone() if it still needs it after the method call returns.

Parameters:

aBoundsInfo - the bounds info

Returns:

true if the query should continue, false if it should stop
