Method Summary

java.lang.String	getDescription() Get the current state of the description field.
boolean	getIsOver() Get the current value of the isOver field.
boolean	requiresPointOnly() Flag to notify the user whether the node implementation only needs the hit point information, or it needs everything else as well.

Method Detail

requiresPointOnly

public boolean requiresPointOnly()

Flag to notify the user whether the node implementation only needs the hit point information, or it needs everything else as well. This is an optimisation method that allows the internals of the event model to avoid doing unnecessary work. If the return value is true, then the hitNormal and hitTexCoord parameter values will not be supplied (they'll be null references).

Returns:

true if the node implementation only requires hitPoint information

setDescription

public void setDescription(java.lang.String desc)

Set a new value for the description field.

Parameters:

desc - The new value for the description field

getDescription

public java.lang.String getDescription()

Get the current state of the description field.

Returns:

The current value of description

setIsOver

public void setIsOver(boolean newIsOver)

Set the flag describing whether the pointing device is over this sensor. The result should be that isOver SFBool output only field is set appropriately at the node level.

Parameters:

newIsOver - The new value for isOver

getIsOver

public boolean getIsOver()

Get the current value of the isOver field.

Returns:

The current value of isOver
