Class SafeUriAttributeParser

java.lang.Object
  com.google.gwt.uibinder.attributeparsers.StrictAttributeParser
      com.google.gwt.uibinder.attributeparsers.SafeUriAttributeParser

All Implemented Interfaces:

AttributeParser

public class SafeUriAttributeParser
extends StrictAttributeParser

Parses SafeUri literals or references.

Simple String literals are passed through UriUtils.fromConstantString(String)

Accepts concatenated string expressions, mainly for compatibility with legacy <a href="{foo.bar}{baz.bang}"> abuses. Passes such nonsense through UriUtils.fromString(String)
