getMessage

public java.lang.String getMessage()

Returns error message key

setMessage

public void setMessage(java.lang.String message)

Sets error message key

toSource

public java.lang.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)

Error nodes are not visited during normal visitor traversals, but comply with the AstNode.visit(org.mozilla.javascript.ast.NodeVisitor) interface.

Specified by:

visit in class AstNode

Parameters:

v - the object to call with this node and its children
