Detailed Description

This class represents a database-cursor.

Member Function Documentation

get() [1/2]

template<typename T>

RowReader tntdb::Statement::const_iterator::get

(

T &

ret

)

const

Instantiates a tntdb::RowReader and fetches the value of the first column.

get() [2/2]

template<typename T>

RowReader tntdb::Statement::const_iterator::get	(	T &	ret,
		bool &	nullInd ) const

Instantiates a tntdb::RowReader and fetches the value of the first column and sets the null indicator.

getImpl()

const ICursor * tntdb::Statement::const_iterator::getImpl ( ) const

inline

Returns the actual implementation-class.

operator!=()

bool tntdb::Statement::const_iterator::operator!= ( const const_iterator & c ) const

inline

Returns true, when the cursor does not point to the same iteration as the passed iterator.

operator*()

const Row & tntdb::Statement::const_iterator::operator* ( ) const

inline

Returns the current tntdb::Row-object.

operator++()

const_iterator & tntdb::Statement::const_iterator::operator++

(

)

Fetches the next row.

If no rows are available, the cursor is closed and removed from this class.

operator->()

const Row * tntdb::Statement::const_iterator::operator-> ( ) const

inline

This operator makes the const_iterator look like a pointer.

operator==()

bool tntdb::Statement::const_iterator::operator== ( const const_iterator & c ) const

inline

Returns true, when the cursor points to the same iteration as the passed iterator.
