Method Detail

contains

public boolean contains(Triple t)

Description copied from interface: TripleBunch

Answer true iff this TripleBunch contains a triple .equals to t.

Specified by:

contains in interface TripleBunch

containsBySameValueAs

public boolean containsBySameValueAs(Triple t)

Description copied from interface: TripleBunch

Answer true iff this TripleBunch contains a triple with .sameValueAs subject, predicate, and object. (Typically this only matters for the object. For example, integer literals with different numbers of leading zeroes can be .sameValueAs but not .equals).

Specified by:

containsBySameValueAs in interface TripleBunch

size

public int size()

Answer the number of items currently in this TripleBunch.

Specified by:

size in interface TripleBunch

See Also:

TripleBunch.size()

currentCapacity

public int currentCapacity()

Answer the current capacity of this HashedTripleBunch; for testing purposes only. [Note that the bunch is resized when it is more than half-occupied.]

add

public void add(Triple t)

Description copied from interface: TripleBunch

Add t to the triples in this bunch. If t is already a member, nothing happens. The bunch now .contains this triple.

Specified by:

add in interface TripleBunch

remove

public void remove(Triple t)

Description copied from class: HashCommon

Remove the object key from this hash's keys if it is present (if it's absent, do nothing). If a key is removed, the removeAssociatedValues will be invoked. If a key is moved, the moveAssociatedValues method will be called.

Specified by:

remove in interface TripleBunch

Overrides:

remove in class HashCommon<Triple>

iterator

public ExtendedIterator<Triple> iterator()

Description copied from interface: TripleBunch

Answer an iterator over all the triples in this bunch. It is unwise to .remove from this iterator. (It may become illegal.)

Specified by:

iterator in interface TripleBunch

iterator

public ExtendedIterator<Triple> iterator(HashCommon.NotifyEmpty container)

Description copied from interface: TripleBunch

Answer an iterator over all the triples in this bunch. If use of .remove on this iterator empties the bunch, the emptied method of container is invoked.

Specified by:

iterator in interface TripleBunch
