get in interface LongArray<V>

Parameters:

lIndex - a long index value

Returns:

the object stored at the specified index, or null

add

public long add(V oValue)

Add the passed element value to the LongArray and return the index at which the element value was stored.

Specified by:

add in interface LongArray<V>

Parameters:

oValue - the object to add to the LongArray

Returns:

the long index value at which the element value was stored

exists

public boolean exists(long lIndex)

Determine if the specified index is in use.

Specified by:

exists in interface LongArray<V>

Parameters:

lIndex - a long index value

Returns:

true if a value (including null) is stored at the specified index, otherwise false

remove

public V remove(long lIndex)

Remove the specified key from the LongArray, returning its associated value.

Specified by:

remove in interface LongArray<V>

Parameters:

lIndex - the index of the key to look for in the LongArray

Returns:

the associated value (which can be null) or null if the key is not in the LongArray

remove

public void remove(long lIndexFrom,
                   long lIndexTo)

Remove all nodes in the specified range.

Specified by:

remove in interface LongArray<V>

Parameters:

lIndexFrom - the floor index

lIndexTo - the ceiling index (exclusive)

contains

public boolean contains(V value)

Determine if the LongArray contains the specified element.

More formally, returns true if and only if this LongArray contains at least one element e such that (o==null ? e==null : o.equals(e)).

Specified by:

contains in interface LongArray<V>

Parameters:

value - element whose presence in this list is to be tested

Returns:

true if this list contains the specified element

clear

public void clear()

Specified by:

clear in interface LongArray<V>

isEmpty

public boolean isEmpty()

Test for empty LongArray.

Specified by:

isEmpty in interface LongArray<V>

Returns:

true if LongArray has no nodes

getSize

public int getSize()
