Constructor Details

BasePersistenceGenerator

protected BasePersistenceGenerator()

Creates an instance of specific persistence provider generator base class.

Method Details

generate

public void generate(CodegenContext codegenContext,
 RoundContext roundContext,
 TypeInfo interfaceInfo,
 RepositoryGenerator repositoryGenerator)

Description copied from interface: PersistenceGenerator

Generate persistence provider specific code. There is always just one data repository provider bound to single data repository interface and its implementing class.

Specified by:

generate in interface PersistenceGenerator

Parameters:

codegenContext - code processing and generation context

roundContext - codegen round context

interfaceInfo - data repository interface info

repositoryGenerator - specific data repository code generator

provider

protected abstract String provider()

Name of the provider.

Returns:

provider name

repositoryClassName

protected abstract TypeName repositoryClassName(TypeName baseName)

Data repository interface implementing class name for specific persistence provider.

Parameters:

baseName - repository interface name (target name base)

Returns:

@return implementing class name

generateRepositoryClass

protected abstract void generateRepositoryClass(CodegenContext codegenContext,
 RoundContext roundContext,
 RepositoryGenerator repositoryGenerator,
 RepositoryInfo repositoryInfo,
 TypeName className,
 ClassModel.Builder classModel)

Generate data repository interface implementing class for specific persistence provider.

Parameters:

codegenContext - code processing and generation context.

roundContext - code processing and generation round contexts

repositoryGenerator - specific data repository code generator

repositoryInfo - data repository interface info

className - implementing class name (from {#link repositoryClassName(TypeName)})

classModel - target implementing class model builder
