Constructor Detail

BooleanQualifier

public BooleanQualifier(String key)
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.

Overrides:
addQualifierKeysToSet in class EOQualifier
Following copied from class: com.webobjects.eocontrol.EOQualifier
Parameters:
qualifierKeys - 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
Following copied from interface: com.webobjects.eocontrol.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.
Overrides:
qualifierWithBindings in class EOQualifier
Following copied from class: com.webobjects.eocontrol.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()
Overrides:
toString in class Object

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.
Overrides:
validateKeysWithRootClassDescription in class EOQualifier
Following copied from class: com.webobjects.eocontrol.EOQualifier
Parameters:
classDescription - The EOClassDescription to be checked with the receiver
