public enum Type extends java.lang.Enum<Type>
Enumeration of all possible types accessed by the Inspector API. Note that: - the EMPTY type is used as a placeholder where data is missing. - all integers are put into LONGs; the encoding takes care of packing small integers compactly so this is also efficient. - likeweise DOUBLE is the only floating-point type, but "simple" numbers (like 0.0 or 1.0) are packed compactly anyway. - DATA can be used anything for wrapping anything else serialized as an array of bytes. - maps should be represented as an ARRAY of OBJECTs where each object has the fields "key" and "value".

values
public static Type[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (Type c : Type.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static Type valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
