Initializer the statement node.

Method Detail

visit

public boolean visit(Visitor visitor,
                     java.lang.Object user1,
                     java.lang.Object user2)
              throws NodeException

Specified by:

visit in interface Visitable

Throws:

NodeException

parseLValue

protected void parseLValue(ExpTokenizer tokens)
                    throws SyntaxError

Overrides:

parseLValue in class StatementNode

Throws:

SyntaxError

acceptModifier

protected boolean acceptModifier(Token token)

Overrides:

acceptModifier in class StatementNode

parsePostModifiers

protected void parsePostModifiers(ExpTokenizer tokens)
                           throws SyntaxError

Overrides:

parsePostModifiers in class StatementNode

Throws:

SyntaxError

isOptional

public boolean isOptional()

Returns weather this header is optional. This flag really indicates how far the AssertFailure exceptions should go. If the header is marked optional then the AssertFailure stops there. Otherwise its passed on to the parent header and so on.

hasArray

public boolean hasArray()

getArrayDimension

public ArrayDimensionNode getArrayDimension()

getArrayScalarSize

public int getArrayScalarSize()
                       throws NodeException

Throws:

NodeException

isDefaultCandidate

public boolean isDefaultCandidate()

toString

public java.lang.String toString()

Overrides:

toString in class StatementNode

main

public static void main(java.lang.String[] args)

Test function for StatementNode

Parameters:

args - command line arguments
