java.lang.Object

com.google.javascript.jscomp.PeepholeCollectPropertyAssignments

public class PeepholeCollectPropertyAssignments
extends Object

A pass that looks for assignments to properties of an object or array immediately following its creation using the abbreviated syntax.

E.g. var a = [];a[0] = 0 is optimized to var a = [0] and similarly for the object constructor.

Method Detail

report

protected void report(DiagnosticType diagnostic,
                      Node n)

Helper method for reporting an error to the compiler when applying a peephole optimization.

Parameters:

diagnostic - The error type

n - The node for which the error should be reported

reportCodeChange

protected void reportCodeChange()

Helper method for telling the compiler that something has changed. Subclasses must call these if they have changed the AST.

areNodesEqualForInlining

protected boolean areNodesEqualForInlining(Node n1,
                                           Node n2)

Are the nodes equal for the purpose of inlining? If type aware optimizations are on, type equality is checked.

isASTNormalized

protected boolean isASTNormalized()

Is the current AST normalized? (e.g. has the Normalize pass been run and has the Denormalize pass not yet been run?)
