public EOQualifier qualifierWithBindings(NSDictionary bindings,
                                         boolean requiresAll)
Description copied from class: EOQualifier
Returns a new qualifier substituting all variables with values found in bindings. If requiresAll is true, any variable not found in bindings throws an exception. If requiresAll is false, missing variable values cause the qualifier node to be pruned from the tree.

Specified by:
qualifierWithBindings in class EOQualifier
bindings - bindings dictionary
requiresAll - Value indicating if all the criteria are required
new qualifier substituting all variables with values in bindings


public void validateKeysWithRootClassDescription(EOClassDescription classDesc)
Description copied from class: EOQualifier
Ensures that the receiver contains keys and key paths that belong to or originate from classDescription. This method raises an exception if an unknown key is found, otherwise it returns null to indicate that the keys contained by the qualifier are valid.

Specified by:
validateKeysWithRootClassDescription in class EOQualifier
classDesc - The EOClassDescription to be checked with the receiver


public void addQualifierKeysToSet(NSMutableSet qualKeys)
Description copied from class: EOQualifier
Adds the receiver's qualifier keys to qualifierKeys. The subclasses in the EOControl framework do this by traversing the tree of qualifiers. Node qualifiers (such as EOAndQualifier) recursively invoke this method until they reach a leaf qualifier (such as EOKeyValueQualifier) which adds its key to the set.

Subclasses of EOQualifier must implement this method.

Specified by:
addQualifierKeysToSet in class EOQualifier
qualKeys - The mutable array of qualifier keys


public void encodeWithKeyValueArchiver(EOKeyValueArchiver archiver)
Description copied from interface: EOKeyValueArchiving
Asks the receiver to archive its state into the EOKeyValueArchiver archiver.

Specified by:
encodeWithKeyValueArchiver in interface EOKeyValueArchiving
archiver - the EOKeyValueArchiver

public static Object decodeWithKeyValueUnarchiver(EOKeyValueUnarchiver unarchiver)
