Method Detail

isTransientAttribute

public static boolean isTransientAttribute(java.lang.String attrName)

Checks if a given attributename is a transient attribute by checking if the first char is an underscore

Returns:

true if the given attribute name starts with underscore

checkSyntacticallyValidAttPath

public static void checkSyntacticallyValidAttPath(java.lang.String attrPath)

Da gibts auch schon sowas wie splitBydelimeter]

Parameters:

Returns:

the given String as String-Array splitted at the dots positions

splitAtDelim

                                           java.lang.String attPath)

Checks if the given BO or any BO along the specified attribute path is deleted.

This method traverses the attribute path from the given BO and checks if any BO along the path, including the starting BO, is marked as deleted. It handles cases where the path contains relations to other BOs and returns false if the path is empty or if any attribute along the path does not exist or has a non-BO value (i.e. a many-relation).

Parameters:

schema - The schema used to resolve the BO's entity.

bo - The starting business object.

attPath - The attribute path to traverse.

Returns:

true if the starting BO or any BO along the path is deleted, false otherwise.
