Class PeepholeCollectPropertyAssignments

java.lang.Object
  com.google.javascript.jscomp.PeepholeCollectPropertyAssignments

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.

Constructor Summary
`PeepholeCollectPropertyAssignments()`

Method Summary
`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.
`protected void`	`error(DiagnosticType diagnostic, Node n)` Helper method for reporting an error to the compiler when applying a peephole optimization.
`protected boolean`	`isASTNormalized()` Is the current AST normalized? (e.g.
`protected void`	`reportCodeChange()` Helper method for telling the compiler that something has changed.

public PeepholeCollectPropertyAssignments()

Method Detail

protected void error(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

protected void reportCodeChange()

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

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.

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?)
