Method Detail- 
validatepublic VariableSet validate(DMLProgram dmlProg, VariableSet ids, HashMap<String,ConstIdentifier> constVars, boolean conditional) - Overrides:
- validatein class- StatementBlock
 
 - 
initializeforwardLVpublic 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:
- initializeforwardLVin class- StatementBlock
 
 - 
initializebackwardLVpublic VariableSet initializebackwardLV(VariableSet loPassed) - Overrides:
- initializebackwardLVin class- StatementBlock
 
 - 
setPredicateHopspublic void setPredicateHops(Hop hops) 
 - 
getPredicateHopspublic Hop getPredicateHops() 
 - 
getPredicateLopspublic Lop getPredicateLops() 
 - 
setPredicateLopspublic void setPredicateLops(Lop predicateLops) 
 - 
getInputstoSBpublic ArrayList<String> getInputstoSB() - Overrides:
- getInputstoSBin class- StatementBlock
 
 - 
analyzepublic VariableSet analyze(VariableSet loPassed) - Overrides:
- analyzein class- StatementBlock
 
 - 
updateRepetitionEstimatespublic 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 class- StatementBlock
- Parameters:
- repetitions- estimated for this statement block
