Constructor Detail

JBinaryArithmeticExpression

public JBinaryArithmeticExpression(TokenReference where,
                                   JExpression left,
                                   JExpression right)
Constructs a node in the parsing tree. This method is directly called by the parser.

Parameters:
where - the line of this node in the source code
left - left operand
right - right operand
Method Detail

typecheck

public JExpression typecheck(CExpressionContextType context)
                      throws PositionedError
Typechecks the expression and mutates the context to record information gathered during typechecking.

Parameters:
context - the context in which this expression appears
Returns:
a desugared Java expression (see JExpression.typecheck())
Throws:
PositionedError - if the check fails

typecheckBinaryArith

public abstract JExpression typecheckBinaryArith(CExpressionContextType context)
                                          throws PositionedError
Typechecks a binary arithmetic expression and handles simple optimizations like constant folding.

Parameters:
context - the actual context of analysis
Returns:
a desugared Java expression (see JExpression.typecheck())
Throws:
PositionedError - if checks fail
