Constructor Detail

KubernetesSerialization

public KubernetesSerialization()

Creates a new instance with a fresh ObjectMapper

KubernetesSerialization

public KubernetesSerialization(com.fasterxml.jackson.databind.ObjectMapper mapper,
                               boolean searchClassloaders)

Creates a new instance with the given ObjectMapper, which will be configured for use for kubernetes resource serialization / deserialization.

Parameters:

searchClassloaders - if KubernetesResource should be automatically discovered via ServiceLoader

Method Detail

configureMapper

protected void configureMapper(com.fasterxml.jackson.databind.ObjectMapper mapper)

asJson

public <T> String asJson(T object)

Returns a JSON representation of the given object.

If the provided object contains a JsonAnyGetter annotated method with a Map that contains an entry that overrides a field of the provided object, the Map entry will take precedence upon serialization. Properties won't be duplicated.

Type Parameters:

T - the type of the object being serialized.

Parameters:

object - the object to serialize.

Returns:

a String containing a JSON representation of the provided object.

asYaml

public <T> String asYaml(T object)

Returns a YAML representation of the given object.

If the provided object contains a JsonAnyGetter annotated method with a Map that contains an entry that overrides a field of the provided object, the Map entry will take precedence upon serialization. Properties won't be duplicated.

Type Parameters:

T - the type of the object being serialized.

Parameters:

object - the object to serialize.

Returns:

a String containing a JSON representation of the provided object.

unmarshal

public <T> T unmarshal(InputStream is)

Unmarshals a stream.

The type is assumed to be KubernetesResource

Type Parameters:

T - The target type.

Parameters:

is - The InputStream.

Returns:

returns de-serialized object

unmarshal

public <T> T unmarshal(InputStream is,
                       com.fasterxml.jackson.core.type.TypeReference<T> type)

unmarshal

public <T> T unmarshal(String str)

Unmarshals a String

The type is assumed to be KubernetesResource

Type Parameters:

T - template argument denoting type

Parameters:

str - The String.

Returns:

returns de-serialized object

unmarshal

public <T> T unmarshal(String str,
                       Class<T> type)

Unmarshals a String

Type Parameters:

T - template argument denoting type

Parameters:

str - The String.

type - The target type.

Returns:

returns de-serialized object

unmarshal

public <T> T unmarshal(InputStream is,
                       Class<T> type)

Unmarshals an InputStream.

Type Parameters:

T - Template argument denoting type

Parameters:

is - The InputStream.

type - The type.

Returns:

returns de-serialized object

clone

public <T> T clone(T resource)

Create a copy of the resource via serialization.

Returns:

a deep clone of the resource

Throws:

IllegalArgumentException - if the cloning cannot be performed

convertValue

public <T> T convertValue(Object value,
                          Class<T> type)

constructParametricType

public Type constructParametricType(Class<?> parameterizedClass,
                                    Class<?>... parameterClasses)

getRegisteredKubernetesResource

public Class<? extends io.fabric8.kubernetes.api.model.KubernetesResource> getRegisteredKubernetesResource(String apiVersion,
                                                                                                           String kind)

getUnmatchedFieldTypeModule

public io.fabric8.kubernetes.model.jackson.UnmatchedFieldTypeModule getUnmatchedFieldTypeModule()

registerKubernetesResource

public void registerKubernetesResource(Class<? extends io.fabric8.kubernetes.api.model.KubernetesResource> clazz)

Registers a new resource, which can then be recognized for deserialization

registerKubernetesResource

public void registerKubernetesResource(String apiVersion,
                                       String kind,
                                       Class<? extends io.fabric8.kubernetes.api.model.KubernetesResource> clazz)

Registers a new resource, which can then be recognized for deserialization.

This is for advanced usage scenarios where you have a class that lacks annotations, or you can have the same class represent multiple versions or groups. However the DSL won't work with those classes - the resource(Class) method and other DSL logic only consults annotations via static HasMetadata methods.

convertToJson

public String convertToJson(String input)
