Class ObjectLiteral

All Implemented Interfaces:
Comparable<AstNode>, Iterable<Node>, DestructuringForm

public class ObjectLiteral extends AstNode implements DestructuringForm
AST node for an Object literal (also called an Object initializer in Ecma-262). The elements list will always be non-null, although the list will have no elements if the Object literal is empty.

Node type is Token.OBJECTLIT.

  • Method Details

    • getElements

      public List<ObjectProperty> getElements()
      Returns the element list. Returns an immutable empty list if there are no elements.
    • setElements

      public void setElements(List<ObjectProperty> elements)
      Sets the element list, and updates the parent of each element. Replaces any existing elements.
      Parameters:
      elements - the element list. Can be null.
    • addElement

      public void addElement(ObjectProperty element)
      Adds an element to the list, and sets its parent to this node.
      Parameters:
      element - the property node to append to the end of the list
      Throws:
      IllegalArgumentException - } if element is null
    • setIsDestructuring

      public void setIsDestructuring(boolean destructuring)
      Marks this node as being a destructuring form - that is, appearing in a context such as for ([a, b] in ...) where it's the target of a destructuring assignment.
      Specified by:
      setIsDestructuring in interface DestructuringForm
    • isDestructuring

      public boolean isDestructuring()
      Returns true if this node is in a destructuring position: a function parameter, the target of a variable initializer, the iterator of a for..in loop, etc.
      Specified by:
      isDestructuring in interface DestructuringForm
    • toSource

      public String toSource(int depth)
      Description copied from class: AstNode
      Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

      Note: if the parser was in error-recovery mode, some AST nodes may have null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

      Specified by:
      toSource in class AstNode
      Parameters:
      depth - the current recursion depth, typically beginning at 0 when called on the root node.
    • visit

      public void visit(NodeVisitor v)
      Visits this node, then visits each child property node, in lexical (source) order.
      Specified by:
      visit in class AstNode
      Parameters:
      v - the object to call with this node and its children
