Method Detail

isPrimitive

public static boolean isPrimitive(Class<?> c)

Parameters:

c - Class to test

Returns:

boolean true if the passed in class is a Java primitive, false otherwise. The Wrapper classes Integer, Long, Boolean, etc. are considered primitives by this method.

isJsonType

public static boolean isJsonType(Class<?> c)

Parameters:

c - Class to test

Returns:

boolean true if the passed in class is a Java primitive, false otherwise. The Wrapper classes Integer, Long, Boolean, etc. are considered primitives by this method.

isLogicalPrimitive

public static boolean isLogicalPrimitive(Class<?> c,
                                         Set<Class<?>> logicalPrimitives)

Parameters:

c - Class to test

logicalPrimitives - - set of logical primitives

Returns:

boolean true if the passed in class is a 'logical' primitive. A logical primitive is defined as all Java primitives, the primitive wrapper classes, String, Number, and Date. This covers BigDecimal, BigInteger, AtomicInteger, AtomicLong, as these are 'Number instances. The reason these are considered 'logical' primitives is that they are immutable and therefore can be written without references in JSON content (making the JSON more readable - less @id / @ref), without breaking the semantics (shape) of the object graph being written.
