Examples of FilterBuilder

com.smartgwt.client.widgets.form.FilterBuilder
A form that allows the user to input advanced search criteria, including operators on field values such as "less than", and sub-clauses using "AND" and "OR" operators.
A FilterBuilder produces an {@link com.smartgwt.client.data.AdvancedCriteria} object, which the {@link com.smartgwt.client.data.DataSource} subsystem canuse to filter datasets, including the ability to perform such filtering within the browser for datasets that are completely loaded.
orestes.bloomfilter.FilterBuilder
Builder for Bloom Filters.
org.apache.hadoop.hive.metastore.parser.ExpressionTree.FilterBuilder
org.apache.jackrabbit.oak.plugins.observation.filter.FilterBuilder
Builder for {@link FilterProvider} instances.
org.apache.uima.lucas.indexer.FilterBuilder
org.elasticsearch.index.query.FilterBuilder

org.gephi.filters.spi.FilterBuilder
Filter builder, creating Filter instances for a single type of filters. Provides also the settings panel for the type of filter.
Implementors should add the @ServiceProvider annotation to be registered by the system or call FilterLibrary.addBuilder().
The JPanel returned by the getPanel() method is the settings panel that configures the filter parameters. These parameters can be get and set by using {@link Filter#getProperties()}. Settings panel should always set parameters values in that way. As a result the system will be aware values changed and update the filter.
See {@link CategoryBuilder} for builders that host multiple types of filters. @author Mathieu Bastian @see FilterLibrary

org.jboss.errai.reflections.util.FilterBuilder

an include exclude filter builder

for example:

 Predicate filter1 = FilterBuilder.parse("+.*, -java.*"); Predicate filter2 = new FilterBuilder().include(".*").exclude("java.*");
