Class TypedScopeCreator.FirstOrderFunctionAnalyzer

java.lang.Object

com.google.javascript.jscomp.NodeTraversal.AbstractScopedCallback

com.google.javascript.jscomp.TypedScopeCreator.FirstOrderFunctionAnalyzer

All Implemented Interfaces:

CompilerPass, NodeTraversal.Callback, NodeTraversal.ScopedCallback

Enclosing class:

TypedScopeCreator

private static class TypedScopeCreator.FirstOrderFunctionAnalyzer
extends NodeTraversal.AbstractScopedCallback
implements CompilerPass

Does a first-order function analysis that just looks at simple things like what variables are escaped, and whether 'this' is used.

Method Detail

process

public void process(Node externs,
                    Node root)

Description copied from interface: CompilerPass

Process the JS with root node root. Can modify the contents of each Node tree

Specified by:

process in interface CompilerPass

Parameters:

externs - Top of external JS tree

root - Top of JS tree

enterScope

public void enterScope(NodeTraversal t)

Description copied from interface: NodeTraversal.ScopedCallback

Called immediately after entering a new scope. The new scope can be accessed through t.getScope()

Specified by:

enterScope in interface NodeTraversal.ScopedCallback

Overrides:

enterScope in class NodeTraversal.AbstractScopedCallback

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
