Member Function Documentation

void DatabaseManager.addEventListener	(	[in] String	event_name,
		[in] EventListener	listener
	)

Adds DOM2 event listener for specified event.

Possible values are: event_name: "keyValueChanged", listener: function that has arguments similar to the keyValueChanged interface properties.

Parameters

event_name	Name of the event.
listener	javascript function that has arguments like the properties listed in the listener's interface.

Boolean DatabaseManager.clear

(

)

Clear lookup table.

            var clearReturn = DatabaseManager.clear();

Returns

true if lookup table exists and is cleared successfully; false, otherwise.

String DatabaseManager.read

(

[in] String

key

)

Get data from lookup table of corresponding key. Exceeding size of parameters throws runtime error.

            var readReturn = DatabaseManager.read("ValidKey3");

Parameters

key	String that is queried in lookup table - max size is 255 char.

Returns

data if key is found in lookup table; empty string, otherwise.

void DatabaseManager.removeEventListener	(	[in] String	event_name,
		[in] EventListener	listener
	)

Removes single DOM2 event listener for specified event

Possible values are: event_name: "keyValueChanged", listener: function that has arguments similar to the keyValueChanged interface properties.

Parameters

event_name	Name of the event
listener	named javascript function that has arguments like the properties listed in the listener's interface.

void DatabaseManager.removeEventListener

(

[in] String

event_name

)

Removes all DOM2 event listeners for specified event

Parameters

event_name

Name of the event

removeEventListener([in] String event_name, [in] EventListener listener);

Boolean DatabaseManager.write	(	[in] String	key,
		[in] String	value
	)

Insert key-value pair into lookup table. If key is already exists in lookup table, then its value is updated. That means key is master and unique. Exceeding size of parameters throws runtime error.

            var writeReturn = DatabaseManager.write("ValidKey1", "ValidValue");

Parameters

key	data - max size is 255 char.
value	data - max size is 255 char.

Returns

true if data is written successfully; false, otherwise.
