Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

overlaps

public boolean overlaps(Geometry g)

Checks whether the perceiver radius overlaps the specified geometry.

Specified by:

overlaps in class Perceiver<ElementType extends QuadTreeElement<ElementType>>

contains

public boolean contains(Geometry g)

Specified by:

contains in class Perceiver<ElementType extends QuadTreeElement<ElementType>>

shouldUpdateBasedOnLoc

public boolean shouldUpdateBasedOnLoc(Point loc)

This virtual function returns true if the elements visible to a perceiver should be updated if it moves to the loc supplied. MobilePerceivers determine whether elements should be updated based on whether the new location is further than defaultPerceiverUpdateDistance from the last update position.

Overrides:

shouldUpdateBasedOnLoc in class Perceiver<ElementType extends QuadTreeElement<ElementType>>
