Document

Method for registering a module that can extend functionality provided by this mapper; for example, by adding providers for custom serializers and deserializers.

Usage

From source file:com.chiralbehaviors.CoRE.kernel.Bootstrap.java

private void serialize(String fileName) throws IOException {
    ObjectMapper objMapper = new ObjectMapper();
    objMapper.registerModule(new CoREModule());
    objMapper.writerWithDefaultPrettyPrinter().writeValue(new File(fileName),
            new WorkspaceSnapshot(find(WellKnownProduct.KERNEL_WORKSPACE), em));
