Detailed Description

Helper class to collect various static functions that provide some interfaces used in SMW 1.6 that are no longer available in SMW 1.7.

In particular, this relates to the new data model based on data items instead of data value classes with DB key arrays and singatures.

Since:

1.6

Note:

This class will vanish before SMW 1.7. Please change your code to not require the old interfaces at all.

static SMWCompatibilityHelpers::getSignatureFromDataItemId	(	$	dataItemId,
		$	typeid
	)			[static]

Compatibility function for computing the old getSignature() string based on dataitem IDs.

To maintain full compatibility, the typeid is relevant here, too.

Use SMWDataValueFactory::getDataItemId() if only the $typeid is known.

Parameters:

	$dataItemId	integer
	$typeid	string

Returns:

string

static SMWCompatibilityHelpers::getIndexFromDataItemId	(	$	dataItemId,
		$	typeid,
		$	labelIndex = false
	)			[static]

Compatibility function for computing the old getValueIndex() and getLabelIndex() numbers based on dataitem IDs.

To maintain full compatibility, the typeid is relevant here, too.

Note:

Use SMWDataValueFactory::getDataItemId() if only the $typeid is known.

Parameters:

	$dataItemId	integer
	$typeid	string
	$labelIndex	boolean, if true get the label index, else the value index

Returns:

string
