Event types
The following example illustrates how each type is specified in an event representation. Given the event type definitions:
event Nested {
integer i;
}
event EveryType {
boolean b;
integer i;
float f;
string s;
location l;
sequence<integer> si;
dictionary<integer, string> dis;
Nested n;
}
the following is a valid event representation for an EveryType event:
EveryType (
true, # boolean is true/false (lower-case)
-10, # positive or negative integer
1.73, # float
"foo", # strings are (double) quoted
(1.0,1.0,5.0,5.0), # locations are 4-tuples of float values
[1,2,3], # sequences are enclosed in brackets []
{1:"a",2:"b"}, # dictionaries are enclosed in braces {}
Nested(1) # nested events include event type name
)
Note that this example is split over several lines for clarity; in practice this definition would all be written on the same line.
Types can of course be nested to create more complex structures. For example, the following is a valid event field definition:
sequence<dictionary<integer, Nested> >
and the following is a valid representation of a value for this field:
[{1:Nested(1)}, {2:Nested(2)}, {3:Nested(3)}]
