private ArrayModifiableIntegerDBIDs.Itr()

Method Detail

internalGetIndex

public int internalGetIndex()

Description copied from interface: IntegerDBIDRef

Return the integer value of the object ID.

Specified by:

internalGetIndex in interface DBIDRef

Specified by:

internalGetIndex in interface IntegerDBIDRef

Returns:

integer id

valid

public boolean valid()

Description copied from interface: Iter

Returns true if the iterator currently points to a valid object.

Specified by:

valid in interface Iter

Returns:

a boolean value, whether the position is valid.

advance

public ArrayModifiableIntegerDBIDs.Itr advance()

Description copied from interface: Iter

Moves the iterator forward to the next entry.

Specified by:

advance in interface DBIDArrayIter

Specified by:

advance in interface DBIDIter

Specified by:

advance in interface ArrayIter

Specified by:

advance in interface Iter

Returns:

The iterator itself.

getOffset

public int getOffset()

Description copied from interface: ArrayIter

Get current iterator offset.

Specified by:

getOffset in interface ArrayIter

Returns:

Iterator position

advance

public ArrayModifiableIntegerDBIDs.Itr advance(int count)

Description copied from interface: ArrayIter

Moves the iterator forward or backward by the given offset.

Specified by:

advance in interface DBIDArrayIter

Specified by:

advance in interface ArrayIter

Parameters:

count - offset to move forward or backwards

Returns:

Iterator

retract

public ArrayModifiableIntegerDBIDs.Itr retract()

Description copied from interface: ArrayIter

Moves the iterator backward to the previous entry.

Specified by:

retract in interface DBIDArrayIter

Specified by:

retract in interface ArrayIter

Returns:

Iterator

seek

public ArrayModifiableIntegerDBIDs.Itr seek(int off)

Description copied from interface: ArrayIter

Moves the iterator to the given position

Specified by:

seek in interface DBIDArrayIter

Specified by:

seek in interface ArrayIter

Parameters:

off - Seek offset

Returns:

Iterator

remove

public void remove()

Description copied from interface: DBIDMIter

Remove the object the iterator currently points to. Note: Subsequent calls to DBIDUtil.deref(de.lmu.ifi.dbs.elki.database.ids.DBIDRef) may return a different element. Call DBIDIter.advance() to advance the iterator to the next element for further processing.

Specified by:
