Constructor Detail

ForAST

public ForAST(antlr.Token token)
Create a new for statement AST

Parameters:
token - the token represented by this AST node
Method Detail

parseComplete

public void parseComplete()
Description copied from class: JavaAST
Compute any derived attributes that must be evaluated after the initial parse. The default action is to just tell your children that the parse is complete.

Overrides:
parseComplete in class StatementAST

computeExceptions

protected Type[] computeExceptions()
Description copied from class: StatementAST
Compute the checked exception types that might be thrown by this statement

Specified by:
computeExceptions in class StatementAST
Returns:
an array of types representing the exceptions that this statement might throw

computeControl

protected StatementAST[] computeControl()
Description copied from class: StatementAST
Compute the list of points to which control might flow after this statement

Specified by:
computeControl in class StatementAST
Returns:
a list of statements to which control might pass from this one

getVarList

public VarList getVarList()
Description copied from class: StatementAST
Get the list of variables read, written, and declared by this statement

Specified by:
getVarList in class StatementAST
Returns:
the list of variables read, written, and declared by this statement

getInit

public HasExceptions getInit()
Get the initialization clause of the for loop

Returns:
the initialization clause, which is either a DeclarationAST or a ListAST

getCondition

public ExpressionAST getCondition()
Get the condition clause of the for loop

Returns:
the condition clause

getIncrement

public ExpressionAST getIncrement()
Get the increment clause of the for loop

Returns:
the increment clause

getBody

public StatementAST getBody()
Get the body of the for loop

Returns:
the body
