org.mozilla.javascript.ast.AstNode
org.mozilla.javascript.ast.InfixExpression
public class InfixExpression
AST node representing an infix (binary operator) expression.
The operator is the node's Token type.

Returns relative offset of operator token |
AstNode |
getRight()
Returns the right-hand side of the expression |

void |
setLeftAndRight(AstNode left,
AstNode right)
|
void |
setOperator(int operator)

an exception if the operator is invalid. |
void |
setOperatorPosition(int operatorPosition)
Sets operator token's relative offset |
void |
setRight(AstNode right)
Sets the right-hand side of the expression, and sets its parent to this node. |
java.lang.String |
toSource(int depth)
Emits source code for this node. |
void |
visit(NodeVisitor v)
Visits this node, the left operand, and the right operand. |

AstNode
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.
toSource in class AstNodedepth - the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit in class AstNodev - the object to call with this node and its children
