Class HubMerger<F extends OAObject,T extends OAObject>

java.lang.Object

com.viaoa.hub.HubMerger<F,T>

public class HubMerger<F extends OAObject,T extends OAObject>
extends Object

Used to combine objects from a property path of a root Hub into a single Hub. As any changes are made to any objects included in the property path, the Hub will automatically be updated. Property path can include either type of reference: One or Many.

Examples:

 new HubMerger(hubSalesmen, hubOrders, "customers.orders");
 
 new HubMerger(hubItem, hubForm, "formItem.formSection.formRow.form");
 
 new HubMerger(hubForm, hubItem, "formRows.formSections.formItems.item");

                 boolean bUseBackgroundThread)

Main constructor that includes all of the config params Used to create an new hubMerger that will automatically update a Hub with all of the objects from a property path from a root Hub.

Parameters:

hubRoot - root Hub. The active object of this Hub will be used to get all objects in the propertyPath.

hubCombinedObjects - will have all of the objects from the active object of the hubRoot, using propertyPath. If hubCombinedObjects.getObjectClass() is null, then it will be assigned the correct class.

propertyPath - dot seperated property path from the class of rootHub to the class of combinedHub.

bShareActiveObject - if true then the Active Object from found hub will be shared.

bUseAll - if true, then each object in hubRoot will be used. If false, then only the Active Object is used.

bIncludeRootHub - if the objects in the rootHub should also be included.

Method Detail

setUseBackgroundThread

public void setUseBackgroundThread(boolean b)

getUseBackgroundThread

public boolean getUseBackgroundThread()

getObjectCount

public int getObjectCount()

Number of objects that are used in this merger.

setServerSideOnly

public void setServerSideOnly(boolean b)

This needs to be set to true if it is only created on the server, but client applications will be using the same Hub that is filtered. This is so that changes on the hub will be published to the clients, even if initiated on an OAClientThread.

getSiblingHelper

public OASiblingHelper getSiblingHelper()

getRootHub

public Hub getRootHub()

getCombinedHub

public Hub getCombinedHub()

setEnabled

public void setEnabled(boolean b)

getEnabled

public boolean getEnabled()

getPath

public String getPath()

setDescription

public void setDescription(String desc)

getDescription

public String getDescription()

verify

public void verify()

Note: if multiple threads are making changes that affect the node data, then errors could show up.
