java.lang.Object

com.github.fge.jsonschema.core.util.Dictionary<T>

Type Parameters:

T - the type of values for this dictionary

All Implemented Interfaces:

Frozen<DictionaryBuilder<T>>

@Immutable
public final class Dictionary<T>
extends Object
implements Frozen<DictionaryBuilder<T>>

A dictionary

This class is a wrapper over a Map, where keys are always Strings. The type of values is arbitrary.

This class is immutable. If you want to build a dictionary, you have two options:

• create a new builder using newBuilder();
• create a builder with all elements from an existing dictionary using thaw().

For instance:

     // New builder
     final DictionaryBuilder<Foo> builder = Dictionary.newBuilder();
     // From an existing dictionary
     final DictionaryBuilder<Foo> builder = dict.thaw();
