Class CheckProvidesSorted

java.lang.Object

com.google.javascript.jscomp.lint.CheckProvidesSorted

All Implemented Interfaces:

NodeTraversal.Callback

public final class CheckProvidesSorted
extends java.lang.Object
implements NodeTraversal.Callback

Checks that goog.provide statements are sorted and deduplicated, exposing the necessary information to produce a suggested fix.

Method Summary

Modifier and Type	Method and Description
Node	getFirstNode() Returns the node for the first recognized provide statement.
Node	getLastNode() Returns the node for the last recognized provide statement.
java.lang.String	getReplacement() Returns a textual replacement yielding a canonical version of the provides.
boolean	needsFix() Returns whether the provides need to be fixed, i.e., whether they are *not* already canonical.
boolean	shouldTraverse(NodeTraversal t, Node n, Node parent) Visits a node in pre order (before visiting its children) and decides whether this node's children should be traversed.
void	visit(NodeTraversal t, Node n, Node parent) Visits a node in postorder (after its children have been visited).

Method Detail

getFirstNode

public Node getFirstNode()

Returns the node for the first recognized provide statement.

getLastNode

public Node getLastNode()

Returns the node for the last recognized provide statement.

getReplacement

public java.lang.String getReplacement()

Returns a textual replacement yielding a canonical version of the provides.

needsFix

public boolean needsFix()

Returns whether the provides need to be fixed, i.e., whether they are *not* already canonical.

shouldTraverse

public boolean shouldTraverse(NodeTraversal t,
                              Node n,
                              Node parent)

Description copied from interface: NodeTraversal.Callback

Visits a node in pre order (before visiting its children) and decides whether this node's children should be traversed. If children are traversed, they will be visited by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) in postorder.

Implementations can have side effects (e.g. modifying the parse tree).

Specified by:

shouldTraverse in interface NodeTraversal.Callback

Returns:

whether the children of this node should be visited

visit

public void visit(NodeTraversal t,
                  Node n,
                  Node parent)

Description copied from interface: NodeTraversal.Callback

Visits a node in postorder (after its children have been visited). A node is visited only if all its parents should be traversed (NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node)).

Implementations can have side effects (e.g. modifying the parse tree).

Specified by:

visit in interface NodeTraversal.Callback
