Module jpastreamer.field

Package com.speedment.jpastreamer.field.predicate

package com.speedment.jpastreamer.field.predicate

The different types of predicates generated by Fields are located in this package. The main difference between a Speedment predicate and an ordinary java predicate is that Speedment predicates also carry metadata about the Field and other conditions used to create it. This metadata can be parsed to produce smarter queries runtime.

This package is part of the API. Modifications to classes here should only (if ever) be done in major releases.
