Method Detail

size

public int size()

Specified by:

size in interface IVecInt

shrink

public void shrink(int nofelems)

Remove the latest nofelems elements from the vector

Specified by:

shrink in interface IVecInt

Parameters:

nofelems -

shrinkTo

public void shrinkTo(int newsize)

Specified by:

shrinkTo in interface IVecInt

pop

public IVecInt pop()

d�pile le dernier �l�ment du vecteur. Si le vecteur est vide, ne fait rien.

Specified by:

pop in interface IVecInt

growTo

public void growTo(int newsize,
                   int pad)

Specified by:

growTo in interface IVecInt

ensure

public void ensure(int nsize)

Specified by:

ensure in interface IVecInt

push

public IVecInt push(int elem)

Specified by:

push in interface IVecInt

unsafePush

public void unsafePush(int elem)

Description copied from interface: IVecInt

Push the element in the Vector without verifying if there is room for it. USE WITH CAUTION!

Specified by:

unsafePush in interface IVecInt

clear

public void clear()

Specified by:

clear in interface IVecInt

last

public int last()

Specified by:

last in interface IVecInt

get

public int get(int i)

Specified by:

get in interface IVecInt

unsafeGet

public int unsafeGet(int i)

Specified by:

unsafeGet in interface IVecInt

set

public void set(int i,
                int o)

Specified by:

set in interface IVecInt

contains

public boolean contains(int e)

Specified by:

contains in interface IVecInt

copyTo

public void copyTo(IVecInt copy)

C'est op�rations devraient se faire en temps constant. Ce n'est pas le cas ici.

Specified by:

copyTo in interface IVecInt

Parameters:

copy -

copyTo

public void copyTo(int[] is)

Specified by:

copyTo in interface IVecInt

Parameters:

is -

moveTo

public void moveTo(IVecInt dest)

Specified by:

moveTo in interface IVecInt

moveTo2

Description copied from interface: IVecInt

Move elements inside the vector. The content of the method is equivalent to: vec[dest] = vec[source]

Specified by:

moveTo in interface IVecInt

Parameters:

dest - the index of the destination

source - the index of the source

moveTo

Specified by:

moveTo in interface IVecInt

insertFirst

public void insertFirst(int elem)

Insert an element at the very begining of the vector. The former first element is appended to the end of the vector in order to have a constant time operation.

Specified by:
