Enum Constant Detail

JSON

public static final TopicType JSON

The topic holds values in JSON format.

For efficiency the data is actually held in CBOR (Concise Binary Object Representation) format and values are presented by the Diffusion JSON type.

This is the most flexible type of topic that leverages all of the Diffusion in-server transformation capabilities.

STRING

public static final TopicType STRING

The topic holds values in {java.lang.String String} format.

BINARY

public static final TopicType BINARY

The topic holds values in raw binary format.

INT64

public static final TopicType INT64

The topic holds a 64 bit integer.

This equates to Long.

DOUBLE

public static final TopicType DOUBLE

The topic holds a double precision floating point number.

This equates to Double.

Method Detail

values

public static TopicType[] 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 (TopicType c : TopicType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TopicType valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
