Class Builder

java.lang.Object

org.apache.camel.builder.Builder

public final class Builder
extends Object

A helper class for including portions of the expression and predicate Java DSL

Implementation of this builder should favor build expressions using the definition classes from the org.apache.camel.model.language package, to build the routes using the same types as it would happen when using XML DSL.
