Method Details

create

public static Optional<TypeInfo> create(AptContext ctx,
 TypeName typeName)

Create type information for a type name, reading all child elements.

Parameters:

ctx - annotation processor processing context

typeName - type name to find

Returns:

type info for the type element

Throws:

IllegalArgumentException - when the element cannot be resolved into type info (such as if you ask for a primitive type)

create

public static Optional<TypeInfo> create(AptContext ctx,
 TypeName typeName,
 Predicate<TypedElementInfo> elementPredicate)
                                 throws IllegalArgumentException

Create type information for a type name.

Parameters:

ctx - annotation processor processing environment

typeName - type name to find

elementPredicate - predicate for child elements

Returns:

type info for the type element, or empty if it cannot be resolved

Throws:

IllegalArgumentException

create

public static Optional<TypeInfo> create(AptContext ctx,
 TypeElement typeElement)

Create type information from a type element, reading all child elements.

Parameters:

ctx - annotation processor processing context

typeElement - type element of the type we want to analyze

Returns:

type info for the type element

Throws:

IllegalArgumentException - when the element cannot be resolved into type info (such as if you ask for a primitive type)

create

public static Optional<TypeInfo> create(AptContext ctx,
 TypeElement typeElement,
 Predicate<TypedElementInfo> elementPredicate)
                                 throws IllegalArgumentException

Create type information from a type element.

Parameters:

ctx - annotation processor processing context

typeElement - type element of the type we want to analyze

elementPredicate - predicate for child elements

Returns:

type info for the type element, or empty if it cannot be resolved

Throws:

IllegalArgumentException

createTypedElementInfoFromElement

public static Optional<TypedElementInfo> createTypedElementInfoFromElement(AptContext ctx,
 Element v,
 Elements elements)

Creates an instance of a TypedElementInfo given its type and variable element from annotation processing. If the passed in element is not a ElementKind.FIELD, ElementKind.METHOD, ElementKind.CONSTRUCTOR, or ElementKind.PARAMETER then this method may return empty.

Parameters:

ctx - annotation processing context

v - the element (from annotation processing)

elements - the elements

Returns:

the created instance
