Methods

Modifier and Type	Method and Description
void	add(T e) Adds obj to this.
void	clear() implemented, but *very* inefficient.
ArraySparseSet<T>	clone() Clones the current FlowSet.
boolean	contains(java.lang.Object obj) Deprecated. This method uses linear-time lookup. For better performance, consider using a HashSet instead, if you require this operation.
void	copy(FlowSet<T> destFlow) Copies the current FlowSet into dest.
void	difference(FlowSet<T> otherFlow, FlowSet<T> destFlow) Returns the set difference (this intersect ~other) of this FlowSet and other, putting result into dest.
FlowSet<T>	emptySet() implemented, but inefficient.
boolean	equals(java.lang.Object otherFlow)
void	intersection(FlowSet<T> otherFlow, FlowSet<T> destFlow) Returns the intersection (meet) of this FlowSet and other, putting result into dest.
boolean	isEmpty() Returns true if this FlowSet is the empty set.
java.util.Iterator<T>	iterator() returns an iterator over the elements of the flowSet.
void	remove(int idx)
void	remove(java.lang.Object obj) Removes obj from this.
int	size() Returns the size of the current FlowSet.
java.util.List<T>	toList() Returns a unbacked list of elements in this set.
void	union(FlowSet<T> otherFlow, FlowSet<T> destFlow) Returns the union (join) of this FlowSet and other, putting result into dest.

Description copied from interface: FlowSet

Clones the current FlowSet.

Specified by:

clone in interface FlowSet<T>

Specified by:

clone in class AbstractFlowSet<T>

emptySet

public FlowSet<T> emptySet()

Description copied from class: AbstractFlowSet

implemented, but inefficient.

Specified by:

emptySet in interface FlowSet<T>

Overrides:

emptySet in class AbstractFlowSet<T>

clear

public void clear()

Description copied from class: AbstractFlowSet

implemented, but *very* inefficient.

Specified by:

clear in interface FlowSet<T>

Overrides:

clear in class AbstractFlowSet<T>

size

public int size()

Description copied from interface: FlowSet

Returns the size of the current FlowSet.

Specified by:

size in interface FlowSet<T>

Specified by:

size in class AbstractFlowSet<T>

isEmpty

public boolean isEmpty()

Description copied from interface: FlowSet

Returns true if this FlowSet is the empty set.

Specified by:

isEmpty in interface FlowSet<T>

Specified by:

isEmpty in class AbstractFlowSet<T>

toList

public java.util.List<T> toList()

Returns a unbacked list of elements in this set.

Specified by:

toList in interface FlowSet<T>

Specified by:

toList in class AbstractFlowSet<T>

add

public void add(T e)

Description copied from interface: FlowSet

Adds obj to this.

Specified by:

add in interface FlowSet<T>

Specified by:

add in class AbstractFlowSet<T>

remove

public void remove(java.lang.Object obj)

Description copied from interface: FlowSet

Removes obj from this.

Specified by:

remove in interface FlowSet<T>

Specified by:

remove in class AbstractFlowSet<T>

remove

public void remove(int idx)

union

public void union(FlowSet<T> otherFlow,
         FlowSet<T> destFlow)

Description copied from interface: FlowSet

Returns the union (join) of this FlowSet and other, putting result into dest. dest, other and this could be the same object.

Specified by:

union in interface FlowSet<T>

Overrides:

union in class AbstractFlowSet<T>

intersection

public void intersection(FlowSet<T> otherFlow,
                FlowSet<T> destFlow)

Description copied from interface: FlowSet

Returns the intersection (meet) of this FlowSet and other, putting result into dest. dest, other and this could be the same object.

Specified by:

intersection in interface FlowSet<T>

Overrides:

intersection in class AbstractFlowSet<T>

difference

public void difference(FlowSet<T> otherFlow,
              FlowSet<T> destFlow)

Description copied from interface: FlowSet

Returns the set difference (this intersect ~other) of this FlowSet and other, putting result into dest. dest, other and this could be the same object.

Specified by:

difference in interface FlowSet<T>

Overrides:

difference in class AbstractFlowSet<T>

contains

@Deprecated
public boolean contains(java.lang.Object obj)

Deprecated. This method uses linear-time lookup. For better performance, consider using a HashSet instead, if you require this operation.

Description copied from interface: FlowSet

Returns true if this FlowSet contains obj.

Specified by:

contains in interface FlowSet<T>

Specified by:

contains in class AbstractFlowSet<T>

equals

public boolean equals(java.lang.Object otherFlow)

Overrides:

equals in class AbstractFlowSet<T>

copy

public void copy(FlowSet<T> destFlow)

Description copied from interface: FlowSet

Copies the current FlowSet into dest.

Specified by:

copy in interface FlowSet<T>

Overrides:

copy in class AbstractFlowSet<T>

iterator

public java.util.Iterator<T> iterator()

Description copied from interface: FlowSet

returns an iterator over the elements of the flowSet. Note that the iterator might be backed, and hence be faster in the creation, than doing toList().iterator().

Specified by:

iterator in interface java.lang.Iterable<T>

Specified by:

iterator in interface FlowSet<T>

Specified by:

iterator in class AbstractFlowSet<T>
