Method Detail

getQualifiedName

public static @Nullable Name getQualifiedName(DeclaredType type)

Gets the fully qualified name for a provided type. It returns an empty name if type is an anonymous type.

Parameters:

type - the declared type

Returns:

the name corresponding to that type

isObject

public static boolean isObject(TypeMirror type)

Checks if the type represents a java.lang.Object declared type.

Parameters:

type - the type

Returns:

true iff type represents java.lang.Object

isClass

public static boolean isClass(TypeMirror type)

Checks if the type represents a java.lang.Class declared type.

Parameters:

type - the type

Returns:

true iff type represents java.lang.Class

isString

public static boolean isString(TypeMirror type)

Checks if the type represents a java.lang.String declared type. TODO: it would be cleaner to use String.class.getCanonicalName(), but the two existing methods above don't do that, I guess for performance reasons.

Parameters:

type - the type

Returns:

true iff type represents java.lang.String

isDeclaredOfName

public static boolean isDeclaredOfName(TypeMirror type,
                       CharSequence qualifiedName)

type - the type

Returns:

type iff type represents a declared type of the qualified name

isAnonymousType

public static boolean isAnonymousType(TypeMirror type)

Checks if the type represents an anonymous type, e.g. as a result of an intersection type

Parameters:

type - the declared type

Returns:

true iff the type represents an anonymous type.

isBoxedPrimitive

public static boolean isBoxedPrimitive(TypeMirror type)

isThrowable

public static boolean isThrowable(TypeMirror type)

Returns:

type represents a Throwable type (e.g. Exception, Error)
