Constructor Detail

StringLit_c

public StringLit_c(Position pos,
                   java.lang.String value)

Method Detail

value

public java.lang.String value()

Get the value of the expression.

Specified by:

value in interface StringLit

value

public StringLit value(java.lang.String value)

Set the value of the expression.

Specified by:

value in interface StringLit

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException

Type check the expression.

Specified by:

typeCheck in interface NodeOps

Overrides:

typeCheck in class Node_c

Parameters:

tc - The type checking visitor.

Throws:

SemanticException

toString

public java.lang.String toString()

Overrides:

toString in class Node_c

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)

Write the expression to an output file.

Specified by:

prettyPrint in interface NodeOps

Overrides:

prettyPrint in class Node_c

Parameters:

w - The code writer to which to write.

tr - The pretty printer. This is not a visitor.

breakupString

public java.util.List breakupString()

Break a long string literal into a concatenation of small string literals. This avoids messing up the pretty printer and editors. ak333: made public to allow CppStringLitDel to get to it.

constantValue

public java.lang.Object constantValue()

Description copied from interface: Expr

Returns the constant value of the expression, if any.

Specified by:

constantValue in interface Expr

Specified by:

constantValue in class Lit_c
