Interface ConstantNode

All Superinterfaces:

ASTNode, ExpressionNode, ForLoopInitializerNode, InitializerNode, SizeableNode

All Known Subinterfaces:

CharacterConstantNode, EnumerationConstantNode, FloatingConstantNode, HereOrRootNode, IntegerConstantNode, ProcnullNode, SelfNode, StatenullNode

public interface ConstantNode
extends ExpressionNode

A "constant" in the sense of the C11 Standard. See C11 Sec. 6.4.4. Note that C uses the word "constant" in a limited way. Character, integer, and floating point literals and enumeration constants are all considered "constants". String literals and compound literals (array, structure, and union literals) are not considered constants.

Method Details

constantKind

ConstantNode.ConstantKind constantKind()

getStringRepresentation

String getStringRepresentation()

Returns the representation of the constant exactly as it occurred in the source code.

Returns:

the original representation of this constant in the source code

setStringRepresentation

void setStringRepresentation(String representation)

Sets the value returned by getStringRepresentation().

Parameters:

representation - the original representation of this constant in the source code

getConstantValue

Value getConstantValue()

Returns the actual constant value, obtained by evaluating this constant expression.

Returns:

the value of this constant expression

copy

ConstantNode copy()

Description copied from interface: ASTNode

Returns a deep copy of this AST node. The node and all of its descendants will be cloned. The cloning does not copy analysis or attribute information.

Specified by:

copy in interface ASTNode

copy in interface ForLoopInitializerNode

Specified by:

copy in interface InitializerNode

Specified by:

copy in interface SizeableNode

Returns:

deep copy of this node
