> Key: PIVOT-550
> URL: https://issues.apache.org/jira/browse/PIVOT-550
> Project: Pivot
> Issue Type: Improvement
> Components: wtk
> Reporter: Greg Brown
> Assignee: Noel Grandin
> Priority: Minor
> Fix For: 2.0
>
>
> Currently, this class uses a StringBuilder internally to manage text updates.
> While this is efficient for constructing strings, TextNode is not as
> efficient at handling strings that are not being modified: TextNode#getText()
> calls toString() on the internal StringBuilder, which generates a new String
> instance each time it is called. Since paint operations (which call
> getText()) are likely to occur more often than changes to the text, this is
> most likely producing a number of unnecessary heap allocations.
> TextInput was recently updated to use a StringBuilder to construct new
> Strings when changes are made, but it uses a String instance internally to
> store the text property value. A similar approach could be taken in TextNode.
