The language of Orchids is statically typed.
Orchids knows about the following types. We first find the basic types, which can notably be used in database fields, or in array indices:
| Type | Description |
|---|---|
int |
signed machine integers (32/64 bit) |
uint |
unsigned machine integers (32/64 bit) |
float |
floating-point numbers, corresponding to C’s double |
str |
text strings |
bstr |
binary strings, i.e., raw data |
regex |
compiled regular expression |
ipv4 |
IPv4 network address |
ipv6 |
IPv6 network address |
ctime |
time, given as seconds since the Epoch (00:00:00 UTC, January 1, 1970) |
timeval |
time duration, given as seconds and microseconds |
snmpoid |
SNMP object identifier |
We then find the structured types.
| Type | Description |
|---|---|
event |
Orchids event, as produced by Orchids modules |
db[type1,…,typen] |
in memory database, namely set of n-tuples of elements of type type1,…,typen respectively; each typei must be a basic type, among str, bstr, int, uint, float, ipv4, ipv6, ctime, timeval, snmpoid |
db[*] |
database of arbitrary tuple types; that is, the type of the empty database |
[...[type |
n-dimensional array of elements of type type (n is the number of initial square brackets); the type of indices is not checked, apart from the fact that it should be a basic type |
