Method Detail

isImplicitUsage

boolean isImplicitUsage(PsiElement element)

Returns:

true if element should not be reported as unused

isImplicitRead

boolean isImplicitRead(PsiElement element)

Returns:

true if element should not be reported as "assigned but not used"

isImplicitWrite

boolean isImplicitWrite(PsiElement element)

Returns:

true if element should not be reported as "referenced but never assigned"

isImplicitlyNotNullInitialized

default boolean isImplicitlyNotNullInitialized(PsiElement element)

Returns:

true if the given element is implicitly initialized to a non-null value

isClassWithCustomizedInitialization

default boolean isClassWithCustomizedInitialization(PsiElement element)

Returns:

true if given element is represents a class (or another data structure declaration depending on language) which instances may have implicit initialization steps not directly available in the source code (e.g. Java class initializer is processed via annotation processor and custom steps added)
