Method Detail

get

int get(K element)

Get the weight associated with the given element.

Parameters:

element - an element (edge/vertex).

Returns:

the weight associated with the given element.

getAsObj

@Deprecated
default Integer getAsObj(K element)

Deprecated.

Please use get(Object) instead to avoid un/boxing.

Get the weight associated with the given element.

This method return the weight as an object, and should not be used when its known what type the weights are.

Specified by:

getAsObj in interface Weights<K,Integer>

Parameters:

element - an element (edge/vertex)

Returns:

the weight associated with the given element

set

void set(K element,
         int weight)

Set the weight associated with the given element.

Parameters:

element - an element (edge/vertex).

weight - new weight that will be associated with the given element

setAsObj

@Deprecated
default void setAsObj(K element,
                      Integer weight)

Deprecated.

Please use set(Object, int) instead to avoid un/boxing.

Set the weight associated with the given element.

This method accept the weight as an object, and should not be used when its known what type the weights are.

Specified by:

setAsObj in interface Weights<K,Integer>

Parameters:

element - an element (edge/vertex)

weight - new weight that will be associated with the given element

defaultWeight

int defaultWeight()

Get the default weight of this weights container.

The default weight is the weight associated with all elements that were not explicitly set using set(Object, int).

Returns:

the default weight of this weights container.

defaultWeightAsObj

@Deprecated
default Integer defaultWeightAsObj()

Deprecated.

Please use defaultWeight() instead to avoid un/boxing.

Get the default weight of this weights container.

The default weight is the weight associated with all ids that were not explicitly set. This method return the default weight as an object, and should not be used when its known what type the weights are.

Specified by:

defaultWeightAsObj in interface Weights<K,Integer>

Returns:

the default weight of this weights container

weightInt

default int weightInt(K element)

Get the integer weight of an element.

Implement the WeightFunctionInt interface by using the weights of the container.

Specified by:

weightInt in interface WeightFunctionInt<K>

Parameters:

element - an element identifier

Returns:

the weight of the element
