Annotation Summary

Modifier and Type	Annotation and Description
public @interface	AllowNarrowingCast Allows a method annotated with `CField` to have a value type that is narrower (smaller number of bits) than the C type.
public @interface	AllowWideningCast Allows a method annotated with `CField` to have a value type that is wider (larger number of bits) than the C type.
public @interface	CBitfield Denotes a method as a bitfield access of a `C struct`.
public @interface	CField Denotes a method as a field access of a `C struct`.
public @interface	CFieldAddress Denotes a method as a field address computation of a `C struct`.
public @interface	CFieldOffset Denotes a method as a field offset access of a `C struct`.
public @interface	CPointerTo Denotes Java interface that imports a C pointer type.
public @interface	CStruct Denotes Java interface that imports a C struct.
public @interface	CTypedefOfInfo Informational only.
public @interface	RawField Denotes a method as a field access of a `structured C memory`.
public @interface	RawFieldAddress Denotes a method as a field address computation of a `RawStructure`.
public @interface	RawFieldOffset Denotes a method as a field offset access of a `RawStructure`.
public @interface	RawPointerTo Denotes a Java interface that is a pointer to a `RawStructure`.
public @interface	RawStructure Denotes Java interface that represents C memory, but without a `C struct` definition.
public @interface	UniqueLocationIdentity A `CField` also annotated with this annotation gets a unique `LocationIdentity` assigned, i.e., reads and writes do not interfere with reads and writes to any other field and are optimized without regarding other fields.
