Constructor Details

ForEachStatementTransformer

private ForEachStatementTransformer(TopLevelTransformationContext cc,
 ForEachStatement stmt)

Method Details

compile

public static IRStatement compile(TopLevelTransformationContext cc,
 ForEachStatement stmt)

compile_impl

protected IRStatement compile_impl()

Specified by:

compile_impl in class AbstractStatementTransformer<ForEachStatement>

makeLoop

public static IRForEachStatement makeLoop(TopLevelTransformationContext cc,
 IRExpression rootExpression,
 IType type,
 Symbol identifier,
 Symbol indexSymbol)

Helper for creating iterative loops. Note that after calling this method, you should compile and call gw.internal.gosu.ir.nodes.statement.IRForEachStatement#setBody(gw.internal.gosu.ir.nodes.IRStatement) on the IRForEachStatement. Since the body often depends on symbols introduced in the loop, you must usually compile it after the loop has been created. Thus it cannot be an argument to this function.

makeLoopImpl

private IRForEachStatement makeLoopImpl(TopLevelTransformationContext cc,
 IRExpression rootExpression,
 IType type,
 Symbol identifier,
 Symbol indexSymbol,
 Symbol iteratorIdentifier)

makeIteratorLoop

private void makeIteratorLoop(TopLevelTransformationContext cc,
 IRExpression rootExpression,
 IRForEachStatement forLoop,
 Symbol identifier,
 Symbol iteratorIdentifier)

makeArrayLoop

private void makeArrayLoop(TopLevelTransformationContext cc,
 IRExpression rootExpression,
 IRForEachStatement forLoop,
 Symbol identifier)

makeIntLoop

private void makeIntLoop(TopLevelTransformationContext cc,
 IRExpression rootExpression,
 IRForEachStatement forLoop,
 Symbol identifier)

makeInt

private IRExpression makeInt(IRExpression rootExpression)

isArrayIteration

private static boolean isArrayIteration(IType iterationType)

makeIterator

public static Iterator makeIterator(Object obj,
 boolean bStructuralIterable)
