ICReturn

implements ICTerminalStatement

com.pnfsoftware.jeb.core.units.code.asm.decompiler.ast.ICReturn

Class Overview

C AST interface to represent return statements of methods. Return statements may or may not return expressions.

Examples:

 return;
 
 return 1;

Public Methods

public abstract ICReturn duplicate ()

Deep duplication of the element. Sub-elements are duplicated.

Note: ICClass, ICMethod, ICField, ICIdentifier, ICConstant, ICType and ICLabel are not duplicated.

public abstract ICExpression getExpression ()

Get the (optional) returned expression.

Returns

returned expression, null if none

public abstract boolean returnsVoid ()

Determine if the return statement returns void.

Returns

true if void
