- Description
-
Bitwise or/join operator.
- Returns
-
If there's a single argument, that argument will be returned.
If there are more than two arguments, the result will be:
`|(`|(arg1 , arg2 ), @extras ) .
If arg1 is an object that has an lfun::`|() , that function
will be called with arg2 as the single argument.
If arg2 is an object that has an lfun::``|() , that function
will be called with arg1 as the single argument.
Otherwise the result will be as follows:
arg1 can have any of the following types:
int | The result will be the binary or of arg1 and arg2 .
|
mapping|multiset | The result will be the join of arg1 and arg2 .
|
array | The result will be the concatenation of arg1 and arg2 .
|
string | The result will be the pairwise bitwose or of arg1 and arg2 .
|
type|program | The result will be the type join of arg1 and arg2 .
