public class PeepholeCollectPropertyAssignments extends java.lang.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 tovar 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 typen
- 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?)
