Method Details

toFilePath

public static String toFilePath(TypeName typeName)

Converts the provided name to a type name path.

Parameters:

typeName - the type name to evaluate

Returns:

the file path expression where dots are translated to file separators

toFilePath

public static String toFilePath(TypeName typeName,
 String fileType)

Converts the provided name to a type name path.

Parameters:

typeName - the type name to evaluate

fileType - the file type, typically ".java"

Returns:

the file path expression where dots are translated to file separators

createAnnotationAndValueListFromAnnotations

@Deprecated
public static List<AnnotationAndValue> createAnnotationAndValueListFromAnnotations(Annotation[] annotations)

Deprecated.

switch to use pure annotation processing instead of reflection

Creates an instance from reflective access. Note that this approach will only have visibility to the RetentionPolicy.RUNTIME type annotations.

Parameters:

annotations - the annotations on the type, method, or parameters

Returns:

the new instance

createQualifierAndValueSet

public static Set<QualifierAndValue> createQualifierAndValueSet(Element type)

Creates a set of qualifiers given the owning element.

Parameters:

type - the element type (from anno processing)

Returns:

the set of qualifiers that the owning element has

createQualifierAndValueSet

public static Set<QualifierAndValue> createQualifierAndValueSet(List<? extends AnnotationMirror> annoMirrors)

Creates a set of qualifiers given the owning element's annotation type mirror.

Parameters:

annoMirrors - the annotation type mirrors (from anno processing)

Returns:

the set of qualifiers that the owning element has

createAnnotationAndValueSet

public static Set<AnnotationAndValue> createAnnotationAndValueSet(Element type)

Creates a set of annotations based using annotation processor.

Parameters:

type - the enclosing/owing type element

Returns:

the annotation value set

createAnnotationAndValueSet

public static Set<AnnotationAndValue> createAnnotationAndValueSet(io.github.classgraph.AnnotationInfoList annotationInfoList)

Creates a set of annotations given the owning element.

Parameters:

annotationInfoList - the list of annotations

Returns:

the annotation and value set

extractInjectionPointTypeInfo

public static String extractInjectionPointTypeInfo(Element typeElement,
 AtomicReference<Boolean> isProviderWrapped,
 AtomicReference<Boolean> isListWrapped,
 AtomicReference<Boolean> isOptionalWrapped)

Determines the meta parts making up InjectionPointInfo for annotation processing.

Parameters:

typeElement - the variable / element type

isProviderWrapped - set to indicate that the ip is a provided type

isListWrapped - set to indicate that the ip is a list type

isOptionalWrapped - set to indicate that the ip is an optional type

Returns:

the return type of the injection point

Throws:

IllegalStateException - thrown if internal state inconsistencies are found

isProviderType

public static boolean isProviderType(String typeName)

Determines whether the type is a Provider (or javax equiv) type.

Parameters:

typeName - the type name to check

Returns:

true if Provider or InjectionPointProvider

oppositeOf

public static String oppositeOf(String typeName)

Transposes "jakarta." from and/or to "javax.".

Parameters:

typeName - the type name to transpose

Returns:

the transposed value, or the same if not able to be transposed

isStatic

public static boolean isStatic(Element element)

Returns true if the element is static.

Parameters:

element - the element

Returns:

true if static

isAbstract

public static boolean isAbstract(Element element)

Returns true if the element is abstract.

Parameters:

element - the element

Returns:

true if abstract

toAccess

public static ElementInfo.Access toAccess(Element element)

Determines the access from an Element (from anno processing).

Parameters:

element - the element

Returns:

the access

needToDeclarePackageUsage

public static boolean needToDeclarePackageUsage(String packageName)

Checks whether the package name need to be declared.

Parameters:

packageName - the package name

Returns:

true if the package name needs to be declared

needToDeclareModuleUsage

public static boolean needToDeclareModuleUsage(String moduleName)

Checks whether the module name needs to be declared.

Parameters:
