Method Detail

addQualifierKeysToSet

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

Parameters:

qualKeys - The mutable array of qualifier keys

decodeWithKeyValueUnarchiver

public static Object decodeWithKeyValueUnarchiver(EOKeyValueUnarchiver unarchiver)

description

public String description()

encodeWithKeyValueArchiver

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

Parameters:

archiver - the EOKeyValueArchiver

See Also:

EOKeyValueArchiver

evaluateWithObject

public boolean evaluateWithObject(EOKeyValueCodingAdditions o)

qualifierWithBindings

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

Parameters:

bindings - bindings dictionary

requiresAll - Value indicating if all the criteria are required

Returns:

new qualifier substituting all variables with values in bindings

toString

public String toString()

validateKeysWithRootClassDescription

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

Parameters:

classDesc - The EOClassDescription to be checked with the receiver
