Field Detail

pos

int pos

Current offset.

Constructor Detail

Itr

private Itr()

Constructor.

Method Detail

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 DoubleIntegerDBIDArrayList.Itr advance()

Description copied from interface: Iter

Moves the iterator forward to the next entry.

Specified by:

advance in interface ArrayIter

Specified by:

advance in interface DBIDArrayIter

Specified by:

advance in interface DBIDIter

Specified by:

advance in interface DoubleDBIDIter

Specified by:

advance in interface DoubleDBIDListIter

Specified by:

advance in interface DoubleIntegerDBIDListIter

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 DoubleIntegerDBIDArrayList.Itr advance(int count)

Description copied from interface: ArrayIter

Moves the iterator forward or backward by the given offset.

Specified by:

advance in interface ArrayIter

Specified by:

advance in interface DBIDArrayIter

Specified by:

advance in interface DoubleDBIDListIter

Specified by:

advance in interface DoubleIntegerDBIDListIter

Parameters:

count - offset to move forward or backwards

Returns:

Iterator

retract

public DoubleIntegerDBIDArrayList.Itr retract()

Description copied from interface: ArrayIter

Moves the iterator backward to the previous entry.

Specified by:

retract in interface ArrayIter

Specified by:

retract in interface DBIDArrayIter

Specified by:

retract in interface DoubleDBIDListIter

Specified by:

retract in interface DoubleIntegerDBIDListIter

Returns:

Iterator

seek

public DoubleIntegerDBIDArrayList.Itr seek(int off)

Description copied from interface: ArrayIter

Moves the iterator to the given position

Specified by:

seek in interface ArrayIter

Specified by:

seek in interface DBIDArrayIter

Specified by:

seek in interface DBIDArrayMIter

Specified by:

seek in interface DoubleDBIDListIter

Specified by:

seek in interface DoubleDBIDListMIter

Specified by:

seek in interface DoubleIntegerDBIDListIter

Specified by:

seek in interface DoubleIntegerDBIDListMIter

Parameters:

off - Seek offset

Returns:

Iterator

internalGetIndex

public int internalGetIndex()

Description copied from interface: DBIDRef

Internal only: Get the internal index.

NOT FOR PUBLIC USE - ELKI Optimization engine only.

Specified by:

internalGetIndex in interface DBIDRef

Specified by:

internalGetIndex in interface IntegerDBIDRef

Returns:

Internal index

doubleValue

public double doubleValue()

Description copied from interface: DoubleDBIDIter

Get the double value

Specified by:

doubleValue in interface DoubleDBIDIter

Returns:

double value

remove

public void remove()

Description copied from interface: DBIDMIter

Remove the object the iterator currently points to. Note: Subsequent calls to DBIDUtil.deref(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:

remove in interface DBIDMIter

Specified by:

remove in interface MIter

setDBID

public void setDBID(DBIDRef ref)

Description copied from interface: DBIDArrayMIter

Set the current value. Note: if the iterator is just after the last position, this may be equivalent to an add, but some implementations may not support this operation!

Specified by:

setDBID in interface DBIDArrayMIter

Parameters:

ref - new value

setDouble

public void setDouble(double value)

Description copied from interface: DoubleDBIDListMIter

Update the value at the current position.

Specified by:

setDouble in interface DoubleDBIDListMIter

Parameters:

value - New value

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
