Returns the content of this instance as string.

Here is the caller graph for this function:

get()

def smm.objects.Exchange.get (   id = None,   symbol = None,   city = None  )

static

Query Exchange objects.

There are three ways for querying objects:

• Querying by id returns an Exchange object or None
• Querying by symbol returns an Exchange object or None
• Querying without parameters to get all Exchange objects

The last way returns always a storm.store.ResultSet.

Parameters

id	Returns an Exchange specified by id.
symbol	Returns an Exchange specified by symbol.
city	Returns an Exchange specified by city.

Searching for city:

Searching to an exchange specified by the city parameter searches the database currently SQLite using the LIKE operator.

To balance the different behaviour of LIKE between ascii and unicode sequences. The city parameter is always capitalised.

SQLite documentation of the LIKE operator:

The default behavior of the LIKE operator is to ignore case for ASCII characters. Hence, by default 'a' LIKE 'A' is true. The case_sensitive_like pragma installs a new application-defined LIKE function that can change this behavior. When case_sensitive_like is enabled, 'a' LIKE 'A' is false but 'a' LIKE 'a' is still true.

Sorting:

The result are unsorted

Test:

tests.test_objects.TestObjects.test_Exchange_get()

getCount()

def smm.objects.Exchange.getCount ( )

static

Returns the number of known exchanges.
