Method Detail

createChangeProxy

RecordValue createChangeProxy(RecordProxySetValue proxySet,
                              boolean isLazySpreading)

Created a change proxy on this object.

Parameters:

proxySet -

isLazySpreading -

Returns:

a change proxy on this object

getOriginalRecord

RecordChangeProxy getOriginalRecord()

Returns a record object that is original non-proxy record. If this is a proxy it returns proxied object recursively. If this is not proxy it returns itself.

Returns:

a record object that is original non-proxy record

getProxyLevel

int getProxyLevel()

Gets number of proxies from this object to original non-proxy record. If this is not a proxy it returns 0. If this is a proxy it returns "proxy level of proxied object" + 1.

Returns:

level of wrapping for this object

isProxyOf

boolean isProxyOf(RecordChangeProxy record)

Returns true if this is direct or non-direct proxy of the record.

Parameters:

record -

Returns:

true if this is direct or non-direct proxy of the record

getProxySet

RecordProxySetValue getProxySet()

Returns proxy set in which the proxy is registered.

Returns:

proxy set in which the proxy is registered

isLazySpreadingProxy

boolean isLazySpreadingProxy()

Returns true if the proxy is lazy spreading. It means that all accessed properties are automatically converted to proxy objects and the created proxies are again lazy spreading.

Returns:

true if the proxy is lazy spreading

createCopy

com.whitestein.lsps.engine.state.xml.Copiable createCopy(ModelInstance targetModelInstance)

Creates a copy without references to other objects.

Parameters:

targetModelInstance -

Returns:

creates a copy

finishCopy

void finishCopy(com.whitestein.lsps.engine.state.xml.Copiable source,
                CopyHelper helper)

Copy references.

Parameters:

source -

helper -
