| Expr | | abstract public class Expr extends Node implements Cloneable(Code) | | Expr is the superclass for a number of other classes representing expressions
in byte code. Expressions are typed and may be nested.

| public | Expr(Type type)
Constructor. |
| Method Summary | |
| public void | cleanupOnly()
Cleans up this expression only, not its children. | | abstract public Object | clone()
| | public Object | comparator()
Returns an Object that can be used to compare other Expr to this. | | protected Expr | copyInto(Expr expr)
Copies the contents of another expression in this one. | | public DefExpr | def()
Returns the expression in which this Expr is defined. | | abstract public boolean | equalsExpr(Expr other)
Compares this expression to another. | | abstract public int | exprHashCode()
Returns the hash code for this expresion. | | public boolean | isDef()
Returns whether or not this expression is a defining occurrence. | | public void | setDef(DefExpr def)
Sets the expression that defines this expression. | | public boolean | setType(Type type)
Sets the type of this expression. | | public Stmt | stmt()
Returns the statement to which this expression belongs. | | public Type | type()

| Expr | | public Expr(Type type)(Code) | | Constructor. Initializes an expression with a given type.
Parameters:
type - The initial Type (descriptor) of this expression. |
| cleanupOnly | | public void cleanupOnly()(Code) | | Cleans up this expression only, not its children.
|
| comparator | | public Object comparator()(Code) | | Returns an Object that can be used to compare other Expr to this.
|
| copyInto | | protected Expr copyInto(Expr expr)(Code) | | Copies the contents of another expression in this one.
Parameters:
expr - The expression from which to copy. |
| def | | public DefExpr def()(Code) | | Returns the expression in which this Expr is defined.
|
| equalsExpr | | abstract public boolean equalsExpr(Expr other)(Code) | | Compares this expression to another.
Parameters:
other - Expr to which to compare this. |
| exprHashCode | | abstract public int exprHashCode()(Code) | | Returns the hash code for this expresion.
|
| isDef | | public boolean isDef()(Code) | | Returns whether or not this expression is a defining occurrence. By
default, false is returned.
|
| setDef | | public void setDef(DefExpr def)(Code) | | Sets the expression that defines this expression.
Parameters:
def - Defining expression. |
| setType | | public boolean setType(Type type)(Code) | | Sets the type of this expression. Returns whether or not the type changed
as a result of calling this method.
|
| stmt | | public Stmt stmt()(Code) | | Returns the statement to which this expression belongs. It essentially
searches up the expression tree for this expression's first ancestor
which is a Stmt.
|
| type | | public Type type()(Code) | | Returns the Type of this expression.
