Class ModelStream

java.lang.Object

sc.lang.SemanticNode

sc.lang.java.ModelStream

All Implemented Interfaces:

ISemanticNode, ICustomResolver, ILifecycle

public class ModelStream
extends SemanticNode
implements ICustomResolver

Stores a stream of changes that need to be made to a model. This object is used both for synchronization and for updating an application when the source code changes. It's the main data structure that stores info used in a sync update to/from the client. When the serialization format is 'stratacode', you can create the model stream by parsing the input using the ModelStream parselet in the JavaLanguage. Or a model stream can be created in the code from UpdateInstanceInfo - when changes are detected after the source code is refreshed (in this case, it represents the changes to the code since the source was last refreshed). The model stream can also be created from other serialization formats like JSON.

Field Detail

modelList

public SemanticNodeList<JavaModel> modelList

isSyncStream

syncCtx

public SyncManager.SyncContext syncCtx

bindCtx

public BindingContext bindCtx

useRuntimeResolution

public boolean useRuntimeResolution

globalModel

public JavaModel globalModel

globalType

public ClassDeclaration globalType

Constructor Detail

ModelStream

public ModelStream()

ModelStream

public ModelStream(boolean isSyncStream)

Method Detail

convertToJS

public java.lang.StringBuilder convertToJS(java.lang.String destName,
                                           java.lang.String defaultScope)

updateRuntime

public void updateRuntime(java.lang.String destName,
                          java.lang.String defaultScope,
                          boolean applyRemoteReset)

This is called to apply the model stream to the system using the supplied default scope.

setLayeredSystem

public void setLayeredSystem(LayeredSystem sys)

resolveType

public java.lang.Object resolveType(java.lang.String currentPackage,
                                    java.lang.String typeName,

                                    TypeDeclaration fromType)

Returns the type of the object with the given name - for compile time checks

Specified by:
