Method Detail

get

double 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 Double getAsObj(K element)

Deprecated.

Description copied from interface: Weights

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,Double>

Parameters:

element - an element (edge/vertex)

Returns:

the weight associated with the given element

set

void set(K element,
         double 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,
                      Double weight)

Deprecated.

Description copied from interface: Weights

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,Double>

Parameters:

element - an element (edge/vertex)

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

defaultWeight

double 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, double).

Returns:

the default weight of this weights container.

defaultWeightAsObj

@Deprecated
default Double defaultWeightAsObj()

Deprecated.

Description copied from interface: Weights

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,Double>

Returns:

the default weight of this weights container

weight

default double weight(K element)

Get the weight of an element.

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

Specified by:

weight in interface WeightFunction<K>

Parameters:

element - an element identifier

Returns:

the weight of the element
