validate
public VariableSet validate(DMLProgram dmlProg, VariableSet ids, HashMap<String,ConstIdentifier> constVars, boolean conditional)
TODO: DRB: This needs to be changed to reflect: 1) Default values for variables -- need to add R styled check here to make sure that once vars with default values start, they keep going to the right 2) The other parameters for External Functions- Overrides:

getFunctionOpType
public FunctionOp.FunctionType getFunctionOpType()
-
initializeforwardLV
public VariableSet initializeforwardLV(VariableSet activeInPassed)
Description copied from class:StatementBlockFor each statement: gen rule: for each variable read in current statement but not updated in any PRIOR statement, add to gen Handles case where variable both read and updated in same statement (i = i + 1, i needs to be added to gen) kill rule: for each variable updated in current statement but not read in this or any PRIOR statement, add to kill.- Overrides:

public boolean isRecompileOnce()
-
setNondeterministic
public void setNondeterministic(boolean flag)
- Overrides:

cloneFunctionBlock
public Types.FunctionBlock cloneFunctionBlock()
- Specified by:
cloneFunctionBlockin interfaceTypes.FunctionBlock
-
updateRepetitionEstimates
public void updateRepetitionEstimates(double repetitions)
Description copied from class:StatementBlockUpdates the repetition estimate for this statement block and all contained hops. FunctionStatementBlocks are loaded from the function dictionary and repetitions are estimated for the contained statement blocks. This method is overridden in the subclasses of StatementBlock.- Overrides:
updateRepetitionEstimatesin classStatementBlock- Parameters:
repetitions- estimated for this statement block
