The "rightHandSide" structural property of this node type.

Since:

3.0

---

PROPERTY_DESCRIPTORS

private static final java.util.List PROPERTY_DESCRIPTORS

A list of property descriptors (element type: StructuralPropertyDescriptor), or null if uninitialized.

---

assignmentOperator

private Assignment.Operator assignmentOperator

The assignment operator; defaults to Assignment.Operator.ASSIGN

---

private Expression leftHandSide

The left hand side; lazily initialized; defaults to an unspecified, but legal, simple name.

---

rightHandSide

private Expression rightHandSide

The right hand side; lazily initialized; defaults to an unspecified, but legal, simple name.

Constructor Detail

Assignment

Assignment(AST ast)

Creates a new AST node for an assignment expression owned by the given AST. By default, the node has an assignment operator, and unspecified left and right hand sides.

Method Detail

propertyDescriptors

public static java.util.List propertyDescriptors(int apiLevel)

Returns a list of structural property descriptors for this node type. Clients must not modify the result.

Since:

3.0

---

internalStructuralPropertiesForType

final java.util.List internalStructuralPropertiesForType(int apiLevel)

Description copied from class: ASTNode

Returns a list of property descriptors for this node type. Clients must not modify the result. This abstract method must be implemented in each concrete AST node type.

N.B. This method is package-private, so that the implementations of this method in each of the concrete AST node types do not clutter up the API doc.

Specified by:

internalStructuralPropertiesForType in class ASTNode

---

internalGetSetObjectProperty

final java.lang.Object internalGetSetObjectProperty(SimplePropertyDescriptor property,
                                                    boolean get,
                                                    java.lang.Object value)

Description copied from class: ASTNode

Sets the value of the given property for this node. The default implementation of this method throws an exception explaining that this node does not have such a property. This method should be extended in subclasses that have at leasy one simple property whose value type is a reference type.

Overrides:

internalGetSetObjectProperty in class ASTNode

---

internalGetSetChildProperty

final ASTNode internalGetSetChildProperty(ChildPropertyDescriptor property,
                                          boolean get,
                                          ASTNode child)

Description copied from class: ASTNode

Sets the child value of the given property for this node. The default implementation of this method throws an exception explaining that this node does not have such a property. This method should be extended in subclasses that have at leasy one child property.

Overrides:

internalGetSetChildProperty in class ASTNode

---

getNodeType0

final int getNodeType0()

Description copied from class: ASTNode

Returns an integer value identifying the type of this concrete AST node.

This internal method is implemented in each of the concrete node subclasses.

Specified by:

getNodeType0 in class ASTNode

---

clone0

ASTNode clone0(AST target)

Description copied from class: ASTNode

Returns a deep copy of the subtree of AST nodes rooted at this node. The resulting nodes are owned by the given AST, which may be different from the AST of this node. Even if this node has a parent, the result node will be unparented.

This method must be implemented in subclasses.

This method does not report pre- and post-clone events. All callers should instead call clone(AST) to ensure that pre- and post-clone events are reported.

N.B. This method is package-private, so that the implementations of this method in each of the concrete AST node types do not clutter up the API doc.

Specified by:

clone0 in class ASTNode

---

subtreeMatch0

final boolean subtreeMatch0(ASTMatcher matcher,
                            java.lang.Object other)

Description copied from class: ASTNode

Returns whether the subtree rooted at the given node matches the given other object as decided by the given matcher.

This internal method is implemented in each of the concrete node subclasses.

Specified by:

subtreeMatch0 in class ASTNode

---

accept0

void accept0(ASTVisitor visitor)

Description copied from class: ASTNode

Accepts the given visitor on a type-specific visit of the current node. This method must be implemented in all concrete AST node types.

General template for implementation on each concrete ASTNode class:

 
 boolean visitChildren = visitor.visit(this);
 if (visitChildren) {
    // visit children in normal left to right reading order
    acceptChild(visitor, getProperty1());
    acceptChildren(visitor, rawListProperty);
    acceptChild(visitor, getProperty2());
 }
 visitor.endVisit(this);
 
 

Note that the caller (accept) take cares of invoking visitor.preVisit(this) and visitor.postVisit(this).

Specified by:

accept0 in class ASTNode

---

getOperator

public Assignment.Operator getOperator()

Returns the operator of this assignment expression.

---

setOperator

public void setOperator(Assignment.Operator assignmentOperator)

Sets the operator of this assignment expression.

---

getLeftHandSide

public Expression getLeftHandSide()

Returns the left hand side of this assignment expression.

---

setLeftHandSide

public void setLeftHandSide(Expression expression)

Sets the left hand side of this assignment expression.

---

getRightHandSide

public Expression getRightHandSide()

Returns the right hand side of this assignment expression.

---

setRightHandSide

public void setRightHandSide(Expression expression)

Sets the right hand side of this assignment expression.

memSize

int memSize()

Description copied from class: ASTNode

Returns an estimate of the memory footprint of this node in bytes. The estimate does not include the space occupied by child nodes.

Specified by:

memSize in class ASTNode

---

treeSize

int treeSize()

Description copied from class: ASTNode

Returns an estimate of the memory footprint in bytes of the entire subtree rooted at this node.

N.B. This method is package-private, so that the implementations of this method in each of the concrete AST node types do not clutter up the API doc.
