Interner

public Interner()

Interner

public Interner(int minimumCapacity)

grow

public void grow(int minimumCapacity)

Ensures that the set has at least the specifies capacity. Higher capacity ensures fewer collisions hence faster lookup. Does nothing if the specified capacity is smaller than the current capacity.

intern

public E intern(E object)

getEntry

protected Interner.Entry<E> getEntry(int hashCode)

Gets the first entry in the table with exactly the given hash code. It's very useful to call Interner.Entry.getNextEntry() to yield the next entry with exactly this same hash code.

hashCode

protected int hashCode(E object)

equals

protected boolean equals(E object,
                         E otherObject)

Returns true if the two objects are to be considered equal. The first object will always be the one passed in as an argument to add, contains, get, intern(Object), #remove(Object).

createEntry

protected Interner.Entry<E> createEntry(E object,
                                        int hashCode)

addEntry

protected void addEntry(Interner.Entry<E> entry)

Adds a new entry, ensures the capacity is sufficient and increases the size.
