ICOperation
implements ICLeftExpression| com.pnfsoftware.jeb.core.units.code.asm.decompiler.ast.ICOperation |
Class Overview
C AST interface to represent arithmetic and logical expressions.
An expression consists of one or two members (the left and right members) and an operator. The left member is optional, and should be null for unary operators.
A third member may be specified for ternary expressions.
Examples:
a + 1 a * ((int)b - foo()) !x x ^ y | z c ? a: b

Public Methods
public abstract ICOperation duplicate ()
Deep duplication of the element. Sub-elements are duplicated.
Note: ICClass, ICMethod, ICField, ICIdentifier,
ICConstant, ICType and ICLabel are not duplicated.
public abstract int getCountOfOperands ()
public abstract boolean mirror (ICOperatorFactory of)
Mirror the operation order, whenever possible. The object is modified.
Returns
- true if mirroring was possible, false otherwise
public abstract boolean reverse (ICOperatorFactory of)
Logical negation of the operation, whenever possible. The object is modified.
Returns
- true if reversing was possible, false otherwise
public abstract void setOperator (ICOperator operator)
Set the operator for the expression. Dangerous method! the operator type is not checked, it is the caller's responsibility to do so.
Parameters
| operator | operator, cannot be null |
