Detailed Description

A class to traverse the observations of a TimeSeries.

This class provides a mechanism to traverse the time series observations sequentially, ordered by time.

An example of use:

TimeSeriesIterator it = tj.begin(); while(it!=tj.end()) { DateTime* t = it.getTime(); double v = it.getDouble(); //or getValue() or getInt or... ++it; }

Member Function Documentation

double te::st::TimeSeriesIterator::getDouble

(

)

const

It returns the attribute value as a double pointed by the internal cursor.

Returns

A pointer to the attribute value as a double pointed by the internal cursor.

int te::st::TimeSeriesIterator::getInt

(

)

const

It returns the attribute value as an integer pointed by the internal cursor.

Returns

A pointer to the attribute value as an integer pointed by the internal cursor.

std::string te::st::TimeSeriesIterator::getString

(

)

const

It returns the attribute value as a string pointed by the internal cursor.

Returns

A pointer to the attribute value as a string pointed by the internal cursor.

te::dt::DateTime* te::st::TimeSeriesIterator::getTime

(

)

const

It returns the datetime pointed by the internal cursor.

Returns

A pointer to the datetime pointed by the internal cursor.

Note

The caller will NOT take the ownership of the returned pointer.

te::dt::AbstractData* te::st::TimeSeriesIterator::getValue

(

)

const

It returns the attribute value pointed by the internal cursor.

Returns

A pointer to the attribute value pointed by the internal cursor.

Note

The caller will NOT take the ownership of the returned pointer.

bool te::st::TimeSeriesIterator::operator!=

(

const TimeSeriesIterator &

rhs

)

Operator !=.

TimeSeriesObservation te::st::TimeSeriesIterator::operator*

(

)

const

Prefix operator *.

It returns the observation (a pair of shared pointers to the time and value) pointed by the internal cursor.

TimeSeriesIterator& te::st::TimeSeriesIterator::operator++

(

)

Prefix operator ++.

After using this operator, the internal cursor points to the next TimeSeries observation.

The semantics of prefix is this: Increment the value and then fetch it.

TimeSeriesIterator te::st::TimeSeriesIterator::operator++

(

int

aux

)

Postfix operator ++.

After using this operator, the internal cursor points to the next TimeSeries observation.

The semantics of postfix is: Fetch the value and then increment the original.

TimeSeriesIterator& te::st::TimeSeriesIterator::operator--

(

)

Prefix operator –.

After using this operator, the internal cursor points to the preceding TimeSeries observation.

The semantics of prefix is this: Increment the value and then fetch it.

TimeSeriesIterator te::st::TimeSeriesIterator::operator--

(

int

aux

)

Postfix operator –.

After using this operator, the internal cursor points to the preceding TimeSeries observation.

The semantics of postfix is: Fetch the value and then increment the original.

const TimeSeriesIterator& te::st::TimeSeriesIterator::operator=

(

const TimeSeriesIterator &

rhs

)

Assignment operator.

bool te::st::TimeSeriesIterator::operator==

(

const TimeSeriesIterator &

rhs

)

Operator ==.
