Enclosing class:
ContractCondition<T>
public static final class ContractCondition.Builder<T> extends Object
Builds instances of type ContractCondition. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.
