Returns: True if the attribute value is NULL.

Reimplemented from te::da::DataSet.

Definition at line 155 of file gdal/DataSet.h.

bool te::gdal::DataSet::isPositionValid ( ) const

virtual

It tells if the dataset internal pointer is on a valid position.

Returns: True, if the dataset internal pointer is on a valid position.

void te::gdal::DataSet::loadTypeInfo ( )

private

bool te::gdal::DataSet::move ( std::size_t i )

virtual

It moves the dataset internal pointer to a given position.

Parameters

i	The position the dataset internal pointer must be set up.

Returns: True, if it was possible to move the dataset reading to the given position.

Note: The first item in the collection starts at address 0.

bool te::gdal::DataSet::moveBeforeFirst ( )

virtual

It moves the internal pointer to a position before the first item in the collection.

Returns: True, if it was possible to move to a sentinel position before the first item in the collection.

Note: This method is not supported by FORWARDONLY datasets.

bool te::gdal::DataSet::moveFirst ( )

virtual

It moves the internal pointer to the first item in the collection.

Returns: True, if it was possible to move to the first item in the collection.

Note: This method is not supported by FORWARDONLY datasets.

Implements te::da::DataSet.

bool te::gdal::DataSet::moveLast ( )

virtual

It sets the dataset internal pointer to the last item in the collection.

Returns: True, if it was possible to move to the last item in the collection.

Implements te::da::DataSet.

References m_i, and m_size.

bool te::gdal::DataSet::moveNext ( )

virtual

It moves the internal pointer to the next item of the collection.

You always has to call this method in order to move the internal pointer to the first item in the collection. This method can be used to traverse a dataset.

Returns: True if the internal pointer is on a valid item, or false otherwise.

Note: All dataset types support this method: FORWARDONLY, BIDIRECTIONAL and RANDOM.

bool te::gdal::DataSet::movePrevious ( )

virtual

It moves the internal pointer to the previous item of the collection.

Returns: True, if the internal pointer (cursor position) is on a valid item, or false otherwise.

Note: This method is not supported by FORWARDONLY datasets.

Implements te::da::DataSet.

std::size_t te::gdal::DataSet::size ( ) const

inlinevirtual

It returns the collection size, if it is known.

It may return std::string::npos if the size is not known, or it would be too costly to compute it.

Returns: The size of the collection, if it is known.
