Properties (8)

datacontrolsvisibility

<attribute name="datacontrolsvisibility" type="boolean" />

public var datacontrolsvisibility : Boolean = true;

This attribute is deprecated, and should not be used. Developers should use a view's visible property to control visibility.

_dpevents

<attribute name="_dpevents" />

private var _dpevents;

these are the events that datapaths publish. This is used by the replication manager to copy and delegates that are registered when it replaces the original datapath

__LZisclone

<attribute name="__LZisclone" />

private var __LZisclone = false;

__LZtakeDPSlot

<attribute name="__LZtakeDPSlot" />

private var __LZtakeDPSlot = true;

pooling

<attribute name="pooling" type="boolean" />

public var pooling : Boolean;

This attribute applies to datapaths which match multiple nodes and force replication. See the section on Pooling in the Guide for information about the use of this attribute.

replication

<attribute name="replication" type="string" />

public var replication : String;

Determines whether to use normal or lazy replication, if the datapath matches more than one node. See the section on Replication in the Guide for information about the use of this attribute.

sortorder

<attribute name="sortorder" type="expression" />

public var sortorder : String|Function;

The order to use to sort the dataset if replication occurs. One of ascending or descending to use built in dictionary sort, or a function which compares two strings and returns 1 if the strings are in order, 0 if they are the same, and -1 if they are out of order. To change this attribute, call the setOrder or setComparator method.

sortpath

<attribute name="sortpath" type="string" />

public var sortpath : String;

An XPath to use to obtain the sort key for sorting if replication occurs. To change this attribute, call the setOrder method.

Setters (1)

Setters for virtual properties, to be used with setAttribute. A setter may or may not have a corresponding getter method; consult the Methods list in this section.

Methods (21)

construct()

<method name="construct" args="v, args" />

private function construct(v, args);

destroy()

<method name="destroy" args="recur" />

private function destroy(recur);

Removes the datapath from its parent

__LZApplyData()

<method name="__LZApplyData" args="force" />

private function __LZApplyData(force);

__LZApplyDataOnInit()

<method name="__LZApplyDataOnInit" />

private function __LZApplyDataOnInit();

__LZcheckChange()

<method name="__LZcheckChange" args="chgpkg" />

private function __LZcheckChange(chgpkg);

__LZgetLast()

<method name="__LZgetLast" />

private function __LZgetLast();

__LZgetPosition()

<method name="__LZgetPosition" />

private function __LZgetPosition();

__LZHandleDocChange()

<method name="__LZHandleDocChange" args="who" />

private function __LZHandleDocChange(who);

__LZHandleMultiNodes()

<method name="__LZHandleMultiNodes" args="nodes" />

private function __LZHandleMultiNodes(nodes);

__LZsendUpdate()

<method name="__LZsendUpdate" args="upd, upp" />

private function __LZsendUpdate(upd, upp);

__LZsetCloneManager()

<method name="__LZsetCloneManager" args="m" />

private function __LZsetCloneManager(m);

__LZsetTracking()

<method name="__LZsetTracking" args="who, additive, needscheck" />

private function __LZsetTracking(who, additive : Boolean, needscheck : Boolean);

Overrides LzDatapointer.__LZsetTracking to handle the additive case

retrieveData()

<method name="retrieveData" />

private function retrieveData();

setClonePointer()

<method name="setClonePointer" args="p" />

private function setClonePointer(p);

Called by the clone manager to point the datapath to the right node

setComparator()

<method name="setComparator" args="comparator" />

public function setComparator(comparator);

Sets the comparator for the sort used by the replication manager.

setDataContext()

<method name="setDataContext" args="p, implicit" />

private function setDataContext(p, implicit);

setNodes()

<method name="setNodes" args="nodes" />

public function setNodes(nodes);

Normally, replication is started when a datapath xpath binding returns multiple nodes. This function overides that behavior and forces replication, and replicates over the list of nodes supplied to this function. Note that once this function is called, the replication manager is no longer actively bound to the data it replicates over by its xpath (if it had one); henceforth the replication set can *only* be controlled by calling setNodes.

setOrder()

<method name="setOrder" args="xpath, comparator" />

public function setOrder(xpath : String, comparator);

Orders the replicated nodes based on the value of the path passed in.

setSelected()

<method name="setSelected" args="torf" />

private function setSelected(torf);

toString()

<method name="toString" />

private function toString();

updateData()

<method name="updateData" />

public function updateData();

This method is used to transfer any values that may have been edited in a datamapped UI control back to the dataset. If the current datapath's xpath ends in a terminal selector (an attribute, text(), or name() expression), then the datapath attempts to call its parent's updateData method. If this method is defined, the datapath sets the data element's attribute, text, or name, respectively, to updateData's return value. The method then calls any other updateData on any datapaths which depend on this one for context. In short, to make datamapping work both ways for a given UI control, define a updateData method that returns the value for the data mapped to the node. This is already done for the base LzInputText class, but not for any other LFC classes.

rerunxpath

<attribute name="rerunxpath" />

public var rerunxpath = true;

By default, this is false for instances of datapointer, and true for instances of datapath.
