Throws:

SyntaxError

getStringExpression

public StringNode getStringExpression()

acceptModifier

protected boolean acceptModifier(Token token)

Overrides:

acceptModifier in class StatementNode

getNewlineFlag

public boolean getNewlineFlag()

Returns the state of the newline flag. If true print the newline at end of the string, or if false do not.

Returns:

true print newline, false do not.

getPrefixFlag

public boolean getPrefixFlag()

Returns the state of the display prefix flag. If true a prefix should be displayed, if false then not. Prefix is displayer specific but usually is the name of the protocol with appropriate amount of spaces for alignment.

Returns:

Display prefix if true, otherwise not.

public int getWhereToPrint()

Returns where to print.
