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 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(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(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(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>

copyFreshToExisting

public void copyFreshToExisting(FlowSet<T> destFlow)

Description copied from interface: FlowSet

Copies a *fresh* copy of this to dest. The input (this) is not referenced somewhere else. This allows subclasses for a smarter and faster copying.

iterator

public 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 FlowSet<T>

Specified by:

iterator in interface Iterable<T>

Specified by:

iterator in class AbstractFlowSet<T>
