Field Detail

kind

protected IntLit.Kind kind

The kind of literal: INT or LONG.

Constructor Detail

IntLit_c

public IntLit_c(Position pos,
        IntLit.Kind kind,
        long value)

IntLit_c

public IntLit_c(Position pos,
        IntLit.Kind kind,
        long value,

Method Detail

boundary

public boolean boundary()

Description copied from interface: IntLit

Is this a boundary case, i.e., max int or max long + 1?

Specified by:

boundary in interface IntLit

Returns:

True if this is a boundary case: the literal can only appear as the operand of a unary minus.

value

public long value()

Description copied from interface: IntLit

Get the literal's value.

Specified by:

value in interface IntLit

value

public IntLit value(long value)

Description copied from interface: IntLit

Set the literal's value.

Specified by:

value in interface IntLit

value

protected <N extends IntLit_c> N value(N n,
                           long value)

kind

public IntLit.Kind kind()

Description copied from interface: IntLit

Get the kind of the literal: INT or LONG.

Specified by:

kind in interface IntLit

kind

public IntLit kind(IntLit.Kind kind)

Description copied from interface: IntLit

Set the kind of the literal: INT or LONG.

Specified by:

kind in interface IntLit

kind

protected <N extends IntLit_c> N kind(N n,
                          IntLit.Kind kind)

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException

Description copied from interface: NodeOps

Type check the AST. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

Specified by:

typeCheck in interface NodeOps

Overrides:

typeCheck in class Node_c

Parameters:

tc - The type checking visitor.

Throws:

SemanticException

positiveToString

public java.lang.String positiveToString()

Description copied from interface: IntLit

Print the string as a positive number.

Specified by:

positiveToString in interface IntLit

toString

public java.lang.String toString()

Overrides:

toString in class Node_c

prettyPrint

public void prettyPrint(CodeWriter w,
               PrettyPrinter tr)

Description copied from class: Node_c

Pretty-print the AST using the given CodeWriter.

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.

constantValue

public java.lang.Object constantValue(Lang lang)

Description copied from interface: ExprOps

Return the constant value of the expression, if any. Requires that isConstant() is true.

Specified by:

constantValue in interface ExprOps

Specified by:

constantValue in class Lit_c

precedence

public Precedence precedence()

Description copied from interface: Expr

Get the precedence of the expression.

Specified by:

precedence in interface Expr

Overrides:

precedence in class Lit_c

copy

public Node copy(NodeFactory nf)

Description copied from interface: NodeOps

Produce a copy of this node using the given NodeFactory.

Specified by:

copy in interface NodeOps

Overrides:

copy in class Node_c
