Method Details

getDesc

public EntityFilterDesc getDesc()

Specified by:

getDesc in interface HasDesc<EntityFilterDesc>

getArg

public Object getArg(EntityFilterArg arg)

hasArg

public boolean hasArg(EntityFilterArg arg)

matcher

public <T extends Entity> Predicate<T> matcher(GameContext context,
 Player player,
 Entity host)

matches

public boolean matches(GameContext context,
 Player player,
 Entity entity,
 Entity host)

A method that calls the subclass's test(GameContext, Player, Entity, Entity) implementation that determines whether or not a given entity matches the filter.

EntityFilterArg.TARGET_PLAYER is interpreted as the point of view from which the test(GameContext, Player, Entity, Entity) call is evaluated.

If an EntityFilterArg.AND_CONDITION is specified, the filter's test and the condition must pass. Works The condition uses the player passed into this function, not the EntityFilterArg.TARGET_PLAYER that is potentially specified on this filter. for any filter. The condition uses the player passed into this function, not the EntityFilterArg.TARGET_PLAYER that is potentially specified on this filter.

Parameters:

context -

player -

entity -

host -

Returns:

true if the entity passes the filter, otherwise false.

test

protected abstract boolean test(GameContext context,
 Player player,
 Entity entity,
 Entity host)

The subclasses of this class implement this method to actually perform the logic of the filtering. Observe that results from filtering other entities are not available here; this function is stateless in the sense that an earlier acceptance or rejection of an entity cannot influence the acceptance or rejection of a current entity.

Parameters:

context -

player -

entity -

host -

Returns:

equals

public boolean equals(Object other)

Overrides:

equals in class Object

getTargetedEntities

protected List<Entity> getTargetedEntities(GameContext context,
 Player player,
 Entity host)

setDesc

public void setDesc(Desc<?,?> desc)

Specified by:

setDesc in interface HasDesc<EntityFilterDesc>
