Examples of com.vaadin.data.util.filter.SimpleStringFilter

com.vaadin.data.util.filter.SimpleStringFilter
Simple string filter for matching items that start with or contain a specified string. The matching can be case-sensitive or case-insensitive. This filter also directly supports in-memory filtering. When performing in-memory filtering, values of other types are converted using toString(), but other (lazy container) implementations do not need to perform such conversions and might not support values of different types. Note that this filter is modeled after the pre-6.6 filtering mechanisms, and might not be very efficient e.g. for database filtering. TODO this might still change @since 6.6
