get

public final JsIDBRequest get(IDBKeyRange key)

Description copied from interface: IDBIndex

Returns an IDBRequest object, and, in a separate thread, finds either:

The value in the referenced object store that corresponds to the given key.
The first corresponding value, if key is a key range.

If a value is successfully found, then a structured clone of it is created and set as the result of the request object.

Note: This method produces the same result for: a) a record that doesn't exist in the database and b) a record that has an undefined value. To tell these situations apart, call the openCursor() method with the same key. That method provides a cursor if the record exists, and not if it does not.

IDBRequest get (
  in any key
) raises (IDBDatabaseException);

Parameters

key: The key or key range that identifies the record to be retrieved.

Returns

IDBRequest

A request object on which subsequent events related to this operation are fired.

Exceptions

This method can raise an IDBDatabaseException with the following code:

Attribute	Description
`TRANSACTION_INACTIVE_ERR`	The index's transaction is not active.
`DATA_ERR`	The `key` parameter was not a valid value.
`NOT_ALLOWED_ERR`	The request was made on a source object that has been deleted or removed.

openCursor

public final JsIDBRequest openCursor()

Description copied from interface: IDBIndex

Returns an IDBRequest object, and, in a separate thread, creates a cursor over the specified key range. The method sets the position of the cursor to the appropriate record, based on the specified direction.

If the key range is not specified or is null, then the range includes all the records.
If at least one record matches the key range, then a success event is fired on the result object, with its result set to the new IDBCursor object; the value of the cursor object is set to a structured clone of the referenced value.
If no records match the key range, then then an error event is fired on the request object, with its code set to NOT_FOUND_ERR and a suitable message.

IDBRequest openCursor (
  in optional any? range,

Description copied from interface: IDBIndex

If the key range is not specified or is null, then the range includes all the records.
If at least one record matches the key range, then a success event is fired on the result object, with its result set to the new IDBCursor object; the value of the cursor object is set to the value of the found record.
If no records match the key range, then then an error event is fired on the request object, with its code set to NOT_FOUND_ERR and a suitable message.

IDBRequest openKeyCursor (
  in optional any? range, 
  in optional unsigned short direction
) raises (IDBDatabaseException);

Parameters

range: Optional. The key range to use as the cursor's range.
direction: Optional. The cursor's required direction. See IDBCursor Constants for possible values.

Returns

IDBRequest

A request object on which subsequent events related to this operation are fired.

Exceptions

This method can raise an IDBDatabaseException with the following code:

Attribute	Description
`TRANSACTION_INACTIVE_ERR`	The index's transaction is not active.
`DATA_ERR`	The `key` parameter was not a valid value.
`NOT_ALLOWED_ERR`	The request was made on a source object that has been deleted or removed.
