Class CustomEnumDefinitionProvider

java.lang.Object

com.github.victools.jsonschema.module.jackson.CustomEnumDefinitionProvider

All Implemented Interfaces:

CustomDefinitionProviderV2

public class CustomEnumDefinitionProvider
extends Object
implements CustomDefinitionProviderV2

Implementation of the CustomDefinitionProviderV2 interface for treating enum types as plain strings based on a JsonValue annotation being present with value = true on exactly one argument-free method and/or JsonProperty annotations being present on all enum constants. If no such annotations exist, no custom definition will be returned; thereby falling back on whatever is defined in a following custom definition (e.g. from one of the standard generator Options).

Constructor and Description
CustomEnumDefinitionProvider(boolean checkForJsonValueAnnotatedMethod, boolean checkForJsonPropertyAnnotations) Constructor indicating how to attempt to serialise enum constant values.

Method Summary

Modifier and Type	Method and Description
protected com.fasterxml.classmate.members.ResolvedMethod	getJsonValueAnnotatedMethod(com.fasterxml.classmate.ResolvedType javaType, SchemaGenerationContext context) Look-up the single JsonValue annotated method with value = true and no expected arguments.
protected List<String>	getSerializedValuesFromJsonProperty(com.fasterxml.classmate.ResolvedType javaType, Object[] enumConstants) Check whether the given type is an enum with at least one constant value and each enum constant value has a JsonProperty annotation.
protected List<Object>	getSerializedValuesFromJsonValue(com.fasterxml.classmate.ResolvedType javaType, Object[] enumConstants, SchemaGenerationContext context) Check whether the given type is an enum with at least one constant value and a single JsonValue annotated method with value = true and no expected arguments.

Constructor Detail

CustomEnumDefinitionProvider

public CustomEnumDefinitionProvider(boolean checkForJsonValueAnnotatedMethod,
                                    boolean checkForJsonPropertyAnnotations)

Constructor indicating how to attempt to serialise enum constant values. If both flags are provided as true, the JsonValue annotated method will take precedence over JsonProperty annotations.

Parameters:

checkForJsonValueAnnotatedMethod - whether a single JsonValue annotated method should be invoked on each enum constant value

checkForJsonPropertyAnnotations - whether each enum constant's JsonProperty annotation's value should be used

Method Detail

provideCustomSchemaDefinition

public CustomDefinition provideCustomSchemaDefinition(com.fasterxml.classmate.ResolvedType javaType,
                                                      SchemaGenerationContext context)

Specified by:

provideCustomSchemaDefinition in interface CustomDefinitionProviderV2

getSerializedValuesFromJsonValue

protected List<Object> getSerializedValuesFromJsonValue(com.fasterxml.classmate.ResolvedType javaType,
                                                        Object[] enumConstants,
                                                        SchemaGenerationContext context)

Check whether the given type is an enum with at least one constant value and a single JsonValue annotated method with value = true and no expected arguments.

Parameters:

javaType - encountered type during schema generation

enumConstants - non-empty array of enum constants

context - current generation context

Returns:

results from invoking the JsonValue annotated method for each enum constant (or null if the criteria are not met)

getJsonValueAnnotatedMethod

protected com.fasterxml.classmate.members.ResolvedMethod getJsonValueAnnotatedMethod(com.fasterxml.classmate.ResolvedType javaType,
                                                                                     SchemaGenerationContext context)

Look-up the single JsonValue annotated method with value = true and no expected arguments.

Parameters:

javaType - targeted type to look-up serialization method for

context - generation context providing access to type resolution context

Returns:

single method with JsonValue annotation

getSerializedValuesFromJsonProperty

protected List<String> getSerializedValuesFromJsonProperty(com.fasterxml.classmate.ResolvedType javaType,
                                                           Object[] enumConstants)

Check whether the given type is an enum with at least one constant value and each enum constant value has a JsonProperty annotation.

Parameters:

javaType - encountered type during schema generation

enumConstants - non-empty array of enum constants

Returns:

annotated JsonProperty.value() for each enum constant (or null if the criteria are not met)
