Constructor Detail

AbstractLongArray

public AbstractLongArray()

Method Detail

get

public Object get(long lIndex)

Return the value stored at the specified index.

Specified by:

get in interface LongArray

Parameters:

lIndex - a long index value

Returns:

the object stored at the specified index, or null

add

public long add(Object 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

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

Parameters:

lIndex - a long index value

Returns:

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

remove

public Object remove(long lIndex)

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

Specified by:

remove in interface LongArray

Parameters:

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

Returns:

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

contains

public boolean contains(Object o)

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

Parameters:

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

Returns:

true if this list contains the specified element

clear

public void clear()

Remove all nodes from the LongArray.

Specified by:

clear in interface LongArray

isEmpty

public boolean isEmpty()

Test for empty LongArray.

Specified by:

isEmpty in interface LongArray

Returns:

true if LongArray has no nodes

getSize

public int getSize()

Determine the size of the LongArray.

Specified by:

getSize in interface LongArray

Returns:

the number of nodes in the LongArray

getFirstIndex

public long getFirstIndex()

Determine the first index that exists in the LongArray.

Specified by:

getFirstIndex in interface LongArray

Returns:

the lowest long value, 0 <= n <= Long.MAX_VALUE, that exists in this LongArray, or -1 if the LongArray is empty

getLastIndex

public long getLastIndex()

Determine the last index that exists in the LongArray.

Specified by:

getLastIndex in interface LongArray

Returns:

the highest long value, 0 <= n <= Long.MAX_VALUE, that exists in this LongArray, or -1 if the LongArray is empty

toString

public String toString()

Provide a string representation of the LongArray.

Specified by:

toString in interface LongArray

Returns:

a human-readable String value describing the LongArray instance

equals

public boolean equals(Object o)

Test for LongArray equality.

Specified by:

equals in interface LongArray

Parameters:

o - an Object to compare to this LongArray for equality

Returns:

true if the passed Object is a LongArray containing the same indexes and whose elements at those indexes are equal

clone

public Object clone()

Make a clone of the LongArray. The element values are not deep-cloned.

Specified by:

clone in interface LongArray

Returns:

a clone of this LongArray object
