Class Overview
C AST interface to represent assignments.
Example of a simple assignment:
left = right
A simple assignment can be modified to represent non-standard assignments:
- A combined-operator assignment
- A unary-operator assignment

Public Methods
public abstract ICAssignment duplicate ()
Deep duplication of the element. Sub-elements are duplicated.
Note: ICClass, ICMethod, ICField, ICIdentifier,
ICConstant, ICType and ICLabel are not duplicated.
public abstract ICOperator getCombinedOperator ()
Get the operator used for combined operator assignments
public abstract ICExpression getRight ()
Get the right-hand side of the assignment.
Warning: null for unary operator assignments, and does not represent the final right value for combined operator assignments.
public abstract void getUnaryOperator (boolean[] r)
Get the operator used for a unary operator assignment.
Parameters
| r | will be filled with two values: r[0] is true for ++, false for --; r[1] is true for prefix ++/--, false for postfix ++/-- |
|---|
public abstract boolean isCombinedOperatorAssignment ()
Check if the assignment is a combined operator assignment (+=, -=, ...).
public abstract boolean isSimpleAssignment ()
Check if the assignment is simple, i.e. it is not a combined operator assignment and not a unary operator assignment.
public abstract boolean isUnaryOperatorAssignment ()
Check if the assignment is a unary operator assignment (++, --).
public abstract void setCombinedOperatorAssignment (ICOperator op, ICExpression right)
Set an extra operator, to transform the simple assignment (=) into one of the 11 allowed combined assignment operators.
This operation is irreversible!
Parameters
| op | non-null, can be: MUL, DIV, ADD, SUB, REM, SHL, SHR, USHR, AND, XOR, OR |
|---|---|
| right | optional, updated right member of the assignment |
Throws
| IllegalStateException | if the assignment is a unary operator assignment |
|---|
public abstract void setRight (ICExpression right)
Throws
| IllegalStateException | if the assignment is a unary operator assignment |
|---|
