Implementations

impl DatabaseProxy

pub fn new() -> TangoResult<DatabaseProxy>

Connect to the database.

Note: this always uses the database referenced by the TANGO_HOST environment variable.

pub fn get_device_exported(&self, name_filter: &str) -> TangoResult<DbDatum>

Return a list of exported devices, filtered by the given name, which can include * as wildcard.

The return value will be a DbDatum containing either PropertyValue::Empty or PropertyValue::StringArray with the device names.

pub fn get_device_exported_for_class(
    &self,
    class_name: &str
) -> TangoResult<DbDatum>

Return a list of exported devices, for the given class.

The return value will be a DbDatum containing either PropertyValue::Empty or PropertyValue::StringArray with the device names.

pub fn get_object_list(&self, name_filter: &str) -> TangoResult<DbDatum>

Return a list of objects for which free properties are defined, considering the given name filter, which can include * as a wildcard.

The return value will be a DbDatum containing either PropertyValue::Empty or PropertyValue::StringArray with the object names.

pub fn get_object_property_list(
    &self,
    obj_name: &str,
    name_filter: &str
) -> TangoResult<DbDatum>

    obj_name: &str,
    prop_list: Vec<DbDatum>
) -> TangoResult<Vec<DbDatum>>

Query the database for one or more free properties of the named object.

The value of the input DbDatums is ignored; in the output they contain the property values.

pub fn put_property(
    &mut self,
    obj_name: &str,
    prop_list: Vec<DbDatum>
) -> TangoResult<()>

Update one or more free properties of the named object.

    &mut self,
    obj_name: &str,
    prop_list: &[&str]
) -> TangoResult<()>
