Method Summary

Modifier and Type	Method	Description
protected void	applyState(Module module, net.sf.json.JSONObject serializedState)	For modules only.
QDLStem	convertArgsToStem(Polyad polyad, Object arg, State state, String component)	Converts a couple of different arguments to the form [[a0{,b0}],[a1{,b1}],...,[an{,bn}] or (if a single argument that is a stem) can pass back:
Module	deserializeFromJSON(State state, net.sf.json.JSONObject json, boolean useModule, SerializationState serializationState)
Module	deserializeFromJSON(State state, net.sf.json.JSONObject json, SerializationState serializationState)	This starts the load from the JSON since which type of module to instantiate is needed, so the right module has to exist before Module.deserializeFromJSON(JSONObject, SerializationState) can be called.
void	deserializeUsedModules(State state, net.sf.json.JSONArray jsonArray, SerializationState serializationState)
List<String>	doJavaModuleLoad(State state, String resourceName, JavaModuleConfig javaModuleConfig)	Load a single java module, returning a null if it failed or the FQ name if it worked.
List<String>	doQDLModuleLoad(State state, String resourceName)	Load the module(s) in a single resource.

Method Detail

convertArgsToStem

public QDLStem convertArgsToStem(Polyad polyad,
                                 Object arg,
                                 State state,
                                 String component)

Converts a couple of different arguments to the form [[a0{,b0}],[a1{,b1}],...,[an{,bn}] or (if a single argument that is a stem) can pass back:

{key0:[[a0{,b0}], key1:[a1{,b1}],...}

where the bk are optional. All ak, bk are strings. a,b -> [[a,b]] (pair of arguments, function is dyadic [a,b] ->[[a,b]] (simple list, convert to nested list [a0,a1,...] -> [[a0],[a1],...] allow for scalars Use in both module import and load for consistent arguments

Parameters:

polyad -

state -

component -

Returns:

doJavaModuleLoad

public List<String> doJavaModuleLoad(State state,
                                     String resourceName,
                                     JavaModuleConfig javaModuleConfig)

Load a single java module, returning a null if it failed or the FQ name if it worked.

Parameters:

state -

resourceName -

doQDLModuleLoad

public List<String> doQDLModuleLoad(State state,
                                    String resourceName)

Load the module(s) in a single resource.

Parameters:

state -

resourceName -

Returns:

deserializeFromJSON

public Module deserializeFromJSON(State state,
                                  net.sf.json.JSONObject json,
                                  SerializationState serializationState)
                           throws Throwable

This starts the load from the JSON since which type of module to instantiate is needed, so the right module has to exist before Module.deserializeFromJSON(JSONObject, SerializationState) can be called.

Parameters:

state -

json -

Returns:

Throws:

Throwable

deserializeFromJSON

public Module deserializeFromJSON(State state,
                                  net.sf.json.JSONObject json,
                                  boolean useModule,
                                  SerializationState serializationState)
                           throws Throwable

Parameters:

state -

json -

useModule - if this module is used (i.e. imported to current scope) vs. imported

serializationState -

Returns:

Throws:

Throwable

updateUsedModuleState

public void updateUsedModuleState(net.sf.json.JSONObject jsonObject,
                                  State state,
                                  SerializationState serializationState)
                           throws Throwable

Throws:

Throwable

updateSerializedState

public void updateSerializedState(net.sf.json.JSONObject jsonObject,
                                  State state,
                                  SerializationState serializationState)
                           throws Throwable

There are two steps to deserialzing a workspace. First, run the QDL which sets up the (arbitrarily complex) network of objects. Then make a second pass with any state objects that have been updated.

Parameters:

jsonObject -

serializationState -

Throws:

Throwable

serializeUsedModules

public net.sf.json.JSONArray serializeUsedModules(State state,
                                                  SerializationState serializationState)
                                           throws Throwable

Throws:

Throwable

deserializeUsedModules

public void deserializeUsedModules(State state,
                                   net.sf.json.JSONArray jsonArray,
                                   SerializationState serializationState)
                            throws Throwable

Throws:

Throwable

getStack

protected net.sf.json.JSONArray getStack(net.sf.json.JSONObject state,
                                         String tag)

applyState

protected void applyState(Module module,
                          net.sf.json.JSONObject serializedState)

For modules only. Applies the serialized module state. If the module was created with the shared state, then only the local tables are updated.

Parameters:

module -

serializedState -
