These identifiers indicate the type of a message so that the core can route
it to the correct method in the recipient.
Usage
GETDATA()
SETDATA()
BIOME_SPLIT_CHAR()
Functions
GETDATA(): Message type for retrieving data from a component
SETDATA(): Message type for setting data in a component
BIOME_SPLIT_CHAR(): Character used to separate biome from variable name
Note
Because these identifiers are provided as #define macros in the hector code,
these identifiers are provided in the R interface as functions. Therefore,
these objects must be called to use them; e.g., GETDATA()
instead of the more natural looking GETDATA.
