extendFlowGraph

public static FlowGraphFragment extendFlowGraph(FlowGraph existingFlowGraph,
                                                java.lang.String newSourceCode,
                                                java.lang.String sourceCodeIdentifier,
                                                FlowGraphFragment previousExtension,
                                                LoadNode extenderNode,
                                                boolean asTimeOutEvent,
                                                java.lang.String resultVariableName)

Extends the given flow graph.

Parameters:

existingFlowGraph - the existing flow graph

newSourceCode - new JavaScript code

sourceCodeIdentifier - key to use for the new flow graph fragment

previousExtension - previous extension that should be replaced by this one, or null if none

extenderNode - node in the existing flow graph where the new fragment should be placed

asTimeOutEvent - if true, add the code as a timeout/interval event handler; if false, add the code as ordinary embedded code

resultVariableName - variable name for the expression result, or null if not used

Returns:

new flow graph fragment

extendFlowGraphWithTopLevelFunction

public static Function extendFlowGraphWithTopLevelFunction(java.util.List<java.lang.String> parameterNames,
                                                           java.lang.String source,
                                                           FlowGraph existingFlowgraph,
                                                           SourceLocation.SourceLocationMaker sourceLocationMaker)

Adds a top-level function to the current flowgraph.

extendFlowGraphWithTopLevelFunction

public static Function extendFlowGraphWithTopLevelFunction(java.util.List<java.lang.String> parameterNames,
                                                           java.net.URL sourceFile,
                                                           boolean isHostEnvironment,
                                                           FlowGraph existingFlowgraph,
                                                           SourceLocation.SourceLocationMaker sourceLocationMaker)

Adds a top-level function to the current flowgraph.

Parameters:

parameterNames - pararmeter names of the function

sourceFile - source code of the function body

isHostEnvironment - true if the function is part of the host environment

existingFlowgraph - flowgraph to extend

Returns:

newly created function
