Examples of com.google.gxp.compiler.alerts.AlertSetBuilder

com.google.gxp.compiler.alerts.AlertSetBuilder
Builder for AlertSets. Note that there are very few "read" methods by design. An AlertSetBuilder is intended to be write-only, except for the {@link #buildAndClear()} method which returns a (by contrast, read-only)AlertSet. This is intended to discourage passing AlertSetBuilders between modules. Instead, pass AlertSets around between modules.
