A class to store the proxy information that must be used to access data located in URIs.
Definition: URI.h:50
A class that represents the known capabilities of a specific data source, i.e. this class informs all...
An abstract class for data providers like a DBMS, Web Services or a regular file.
Definition: DataSource.h:120
It represents the SQL query dialect accepted by a given data source.
Definition: SQLDialect.h:56
static te::da::DataSourceCapabilities sm_capabilities
Definition: DataSource.h:97
std::vector< std::string > getTL4Layers()
bool exists(const std::string &dsInfo)
Check the existence of a data source in a driver.
std::vector< std::string > getTL4Tables()
void close()
It closes the data source and clears all the resources used by its internal communication channel.
bool isValid() const
It checks if the data source is valid (available for using).
DataSource(const te::core::URI &uri)
std::string getType() const
It returns the data source type name (in UPPER CASE). Ex: POSTGIS, SQLITE, WFS, WMS,...
TeTheme * getTL4Theme(const ::terralib4::ThemeInfo &theme)
const te::da::DataSourceCapabilities & getCapabilities() const
It returns the known capabilities of the data source.
void open()
It opens the data source and makes it ready for using.
void create(const std::string &dsInfo)
It creates a new data source.
bool isOpened() const
It returns true if the data source is opened, otherwise it returns false.
std::vector< std::string > getTL4Rasters()
int getLayerSRID(const std::string &layerName)
std::unique_ptr< te::da::DataSourceTransactor > getTransactor()
It returns the set of parameters used to set up the access channel to the underlying repository.
const te::da::SQLDialect * getDialect() const
It returns the data source SQL dialect, if there is one.
std::vector< std::pair< std::string, std::string > > getTL4RasterFiles()
void drop(const std::string &dsInfo)
It removes the data source with the connection information from a driver.
~DataSource()
Virtual destructor.
std::vector<::terralib4::ThemeInfo > getTL4Themes()
static te::da::SQLDialect * sm_dialect
Definition: DataSource.h:98
TeDatabase * getTerralib4Db()
TeDatabase * m_db
Definition: DataSource.h:95
std::vector< std::string > getDataSourceNames(const std::string &dsInfo)
It gets the data source names available in a driver.
DataSource(const std::string &connInfo)

#define TETERRALIB4EXPORT
You can use this macro in order to export/import classes and functions from this module.
Definition: Config.h:123
