Class EOGenericRecord

java.lang.Object
  net.wotonomy.control.EOCustomObject
      net.wotonomy.control.EOGenericRecord

All Implemented Interfaces:

EODeferredFaulting, EOEnterpriseObject, EOFaulting, EOKeyValueCoding, EOKeyValueCodingAdditions, EORelationshipManipulation, EOValidation, net.wotonomy.foundation.NSKeyValueCoding, net.wotonomy.foundation.NSKeyValueCodingAdditions

public class EOGenericRecord
extends EOCustomObject

EOGenericRecord extends EOCustomObject to provide a general-purpose implementation, relying entirely on the class description for entity-specific behavior, and storing data in a dictionary.

void	takeValueForKey(java.lang.Object aValue, java.lang.String aKey) Calls willChange and then calls takeStoredValueForKey.
static boolean	usesDeferredFaultCreation() Overridden to return true so that deferred faults are used.
java.lang.Object	valueForKey(java.lang.String aKey) Calls storedValueForKey.

Constructor Detail

EOGenericRecord

protected EOGenericRecord()

Default constructor.

EOGenericRecord

public EOGenericRecord(EOClassDescription aDescription)

Preferred constructor.

EOGenericRecord

public EOGenericRecord(EOEditingContext aContext,
                       EOClassDescription aDescription,
                       EOGlobalID anID)

Compatibility constructor: aContext and anID are ignored.

Method Detail

usesDeferredFaultCreation

public static boolean usesDeferredFaultCreation()

Overridden to return true so that deferred faults are used.

classDescription

public EOClassDescription classDescription()

Returns a class description for this object. Overridden to return the class description passed into the constructor.

Specified by:

classDescription in interface EOEnterpriseObject

Overrides:

classDescription in class EOCustomObject

valueForKey

public java.lang.Object valueForKey(java.lang.String aKey)

Calls storedValueForKey.

Specified by:

valueForKey in interface EOKeyValueCoding

Specified by:

valueForKey in interface net.wotonomy.foundation.NSKeyValueCoding

Overrides:

valueForKey in class EOCustomObject

takeValueForKey

public void takeValueForKey(java.lang.Object aValue,
                            java.lang.String aKey)

Calls willChange and then calls takeStoredValueForKey.

Specified by:

takeValueForKey in interface EOKeyValueCoding

Specified by:

takeValueForKey in interface net.wotonomy.foundation.NSKeyValueCoding

Overrides:

takeValueForKey in class EOCustomObject

storedValueForKey

public java.lang.Object storedValueForKey(java.lang.String aKey)

Calls willRead for the specified key, and returns the corresponding value from the data dictionary. Keys that do not exist will return null.

Specified by:

storedValueForKey in interface EOKeyValueCoding

Specified by:

storedValueForKey in interface net.wotonomy.foundation.NSKeyValueCoding

Overrides:

storedValueForKey in class EOCustomObject

takeStoredValueForKey

public void takeStoredValueForKey(java.lang.Object aValue,
                                  java.lang.String aKey)

Writes the specified value into the data dictionary for the specified key. Nulls are stored as NSNulls in the dictionary. No checking is performed to determine whether the key is a valid attribute key.

Specified by:

takeStoredValueForKey in interface EOKeyValueCoding

Specified by:

takeStoredValueForKey in interface net.wotonomy.foundation.NSKeyValueCoding

Overrides:

takeStoredValueForKey in class EOCustomObject
