Method Detail

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:

validate in class StatementBlock

getFunctionOpType

public FunctionOp.FunctionType getFunctionOpType()

initializeforwardLV

public VariableSet initializeforwardLV(VariableSet activeInPassed)

Description copied from class: StatementBlock

For 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:

initializeforwardLV in class StatementBlock

initializebackwardLV

public VariableSet initializebackwardLV(VariableSet loPassed)

Overrides:

initializebackwardLV in class StatementBlock

analyze

public VariableSet analyze(VariableSet loPassed)

Overrides:

analyze in class StatementBlock

analyze

public VariableSet analyze(VariableSet liPassed,
                           VariableSet loPassed)

setRecompileOnce

public void setRecompileOnce(boolean flag)

isRecompileOnce

public boolean isRecompileOnce()

setNondeterministic

public void setNondeterministic(boolean flag)

Overrides:

setNondeterministic in class StatementBlock

isNondeterministic

public boolean isNondeterministic()

Overrides:

isNondeterministic in class StatementBlock

cloneFunctionBlock

public Types.FunctionBlock cloneFunctionBlock()

Specified by:

cloneFunctionBlock in interface Types.FunctionBlock

updateRepetitionEstimates

public void updateRepetitionEstimates(double repetitions)

Description copied from class: StatementBlock

Updates 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:

updateRepetitionEstimates in class StatementBlock

Parameters:

repetitions - estimated for this statement block
