This class is used to represent an association as part of the data management metadata. An association is used to represent a property of one object which refers to an instance or collection of instance of another managed type. These instances may be created automatically from server side configuration or automatically in the code generated wrappers. It is also possible to create these in those cases where the configuration is defined entirely in the runtime ActionScript code.

Property Detail

pagedUpdates

property

public var pagedUpdates:Boolean = false

When true, updates to the set of associated instances for this association are made in increments of pageSize. When false, the entire set is updated at once.

pageSize

property

public var pageSize:int = 0

Size of page to use for communication of changes to the set of associated instances for this association. Only relevant when pagedUpdates is true.

Constructor Detail

Method Detail

getAttributeMask

()

method

public function getAttributeMask():uint

Bit mask representing the attributes of this managed association. Starting with the smallest order bit: First bit - on when this association is lazy. Second bit - on when the association is loaded on demand. Third bit - on when the association is read only. Foruth bit - on when hierarchical events are enabled. Fifth bit - on when hierarchical events have been set. Sixth bit - on when updates are paged.

Returns

uint — bit mask representing the attributes of this managed association.

readExternal

()

method

public function readExternal(input:IDataInput):void

Parameters

input:IDataInput

setAttributeMask

()

method

public function setAttributeMask(mask:uint):void

Sets the attributes of this association based on the passed in bit mask. Starting with the smallest order bit: First bit - on when this association is lazy. Second bit - on when the association is loaded on demand. Third bit - on when the association is read only. Foruth bit - on when hierarchical events are enabled. Fifth bit - on when hierarchical events have been set. Sixth bit - on when updates are paged.

Parameters

mask:uint — bit mask representing the attributes of this managed association.
