Constructor Details

BaseRepositoryMethodsGenerator

protected BaseRepositoryMethodsGenerator(RepositoryInfo repositoryInfo,
 ClassModel.Builder classModel,
 CodegenContext codegenContext,
 PersistenceGenerator persistenceGenerator)

Creates an instance of data repository interface code generator base class for methods generators.

Parameters:

repositoryInfo - data repository interface info

classModel - target class builder

codegenContext - code processing and generation context

persistenceGenerator - persistence provider specific generator

Method Details

genericReturnTypeArgument

protected static TypeName genericReturnTypeArgument(TypedElementInfo methodInfo)

Extract TypeName of generic argument from provided TypedElementInfo methodInfo return type. Retrieves generic argument from single generic argument types like List or Stream

Parameters:

methodInfo - method info

Returns:

TypeName of generic argument

isListOrCollection

protected static boolean isListOrCollection(TypeName typeName)

Check whether provided TypeName is List or Collection.

Parameters:

typeName - type to check

Returns:

value of true when provided TypeName is List or Collection, value of false otherwise

isStream

protected static boolean isStream(TypeName typeName)

Check whether provided TypeName is Stream.

Parameters:

typeName - type to check

Returns:

value of true when provided TypeName is Stream, value of false otherwise

isSlice

protected static boolean isSlice(TypeName typeName)

Check whether provided TypeName is io.helidon.data.Slice.

Parameters:

typeName - type to check

Returns:

value of true when provided TypeName is io.helidon.data.Slice, value of false otherwise

isPage

protected static boolean isPage(TypeName typeName)

Check whether provided TypeName is io.helidon.data.Page.

Parameters:

typeName - type to check

Returns:

value of true when provided TypeName is io.helidon.data.Page, value of false otherwise

isSliceOrPage

protected static boolean isSliceOrPage(TypeName typeName)

Check whether provided TypeName is io.helidon.data.Slice or io.helidon.data.Page.

Parameters:

typeName - type to check

Returns:

value of true when provided TypeName is io.helidon.data.Slice or io.helidon.data.Page, value of false otherwise

paramElementName

protected static String paramElementName(TypedElementInfo param)

Retrieve name of the method parameter from provided TypedElementInfo param.

Parameters:

param - method parameter info

Returns:

name of the method parameter

generateHeader

protected MethodParams generateHeader(Method.Builder builder,
 TypedElementInfo methodInfo)

Generate method header matching interface prototype and return method parameters.

Parameters:

builder - method builder

methodInfo - method info

Returns:

method parameters

processParam

protected abstract void processParam(MethodParams.Builder builder,
 TypedElementInfo paramInfo)

Process method parameter. Extending class must implement this method to properly handle each parameter of the generated method.

Parameters:

builder - method builder

paramInfo - method parameter info
