java.lang.Object

ru.yojo.codegen.mapper.AbstractMapper

Direct Known Subclasses:

MessageMapper, SchemaMapper

public class AbstractMapper
extends Object

Base class for schema and message mapping logic.

Responsible for:

• Populating VariableProperties from YAML property definitions
• Resolving $ref, polymorphism (oneOf/allOf), collections, maps, enums
• Inferring Java types, validation annotations, and required imports

Method Details

fillProperties

public void fillProperties(String schemaName,
 VariableProperties variableProperties,
 Map<String,Object> currentSchema,
 Map<String,Object> schemas,
 String propertyName,
 Map<String,Object> propertiesMap,
 ProcessContext processContext,
 Map<String,Object> innerSchemas)

Populates a VariableProperties instance from a single property definition in a schema.

Handles:

• Basic metadata: name, description, example, default
• Validation: min/max length/size, pattern, digits, min/max value
• Type/format inference (string, date, uuid, etc.)
• Polymorphism detection (oneOf, allOf, anyOf)
• Delegation to fillVariableProperties(java.lang.String, ru.yojo.codegen.domain.VariableProperties, java.util.Map<java.lang.String, java.lang.Object>, java.util.Map<java.lang.String, java.lang.Object>, java.lang.String, java.util.Map<java.lang.String, java.lang.Object>, ru.yojo.codegen.context.ProcessContext, java.util.Map<java.lang.String, java.lang.Object>) for type resolution
• Required annotations/imports for validation

Parameters:

schemaName - name of the containing schema (for diagnostics)

variableProperties - target to populate

currentSchema - full current schema map (used for required lookup)

schemas - global schemas map (for $ref resolution)

propertyName - raw property name from YAML

propertiesMap - property definition map (e.g., { type: string, format: email })

processContext - current generation context

innerSchemas - accumulator for generated inner schemas (e.g., enums, inner DTOs)

fillVariableProperties

public void fillVariableProperties(String schemaName,
 VariableProperties variableProperties,
 Map<String,Object> currentSchema,
 Map<String,Object> schemas,
 String propertyName,
 Map<String,Object> propertiesMap,
 ProcessContext processContext,
 Map<String,Object> innerSchemas)

Resolves the Java type and metadata for a property, based on its definition.

Dispatches to specialized handlers for:

• Empty property → Object
• format override for type: object (e.g., uuid, date)
• Arrays/collections
• $ref references
• Inner objects (with properties)
• Enums
• Existing classes (format: existing)
• Maps (additionalProperties)
• Polymorphic types

Parameters:

schemaName - schema name (for diagnostics)

variableProperties - target to populate

currentSchema - current schema map

schemas - global schemas map

propertyName - property name

propertiesMap - property definition

processContext - generation context

innerSchemas - inner schema accumulator

fillMessageFromChannel

public static void fillMessageFromChannel(Map<String,Object> allContent,
 Map<String,Object> messagesMap,
 Set<String> excludeSchemas,
 Map<String,Object> mapToMessage,
 String channelName,
 String channelType)

Extracts message definitions from AsyncAPI 2.0 channels/publish/subscribe.

Parameters:

allContent - full spec document

messagesMap - output map to populate

excludeSchemas - schemas to preserve (for polymorphic cases)

mapToMessage - channel message map

channelName - channel name

channelType - "publish" or "subscribe"

fillRequiredAnnotationsAndImports

public static void fillRequiredAnnotationsAndImports(VariableProperties variableProperties,
 Map<String,Object> currentSchema,
 String propertyName)

Adds validation annotations and imports based on required list and field type.

Supports:

• Basic: @NotNull, @NotBlank, @NotEmpty
• Validation groups (groups = {...})
• jakarta vs javax packages (via Spring Boot version)

Parameters:

variableProperties - field metadata

currentSchema - schema containing required list

propertyName - field name
