This module defines Erlang BIFs, guard tests and operators. This module is only of interest to programmers who manipulate Erlang code.
Types:
Name = atom()
Arity = integer()
Returns true if Name/Arity is an Erlang BIF
which is automatically recognized by the compiler, otherwise
false.
guard_bif(Name, Arity) -> bool()
Types:
Name = atom()
Arity = integer()
Returns true if Name/Arity is an Erlang BIF
which is allowed in guards, otherwise false.
type_test(Name, Arity) -> bool()
Types:
Name = atom()
Arity = integer()
Returns true if Name/Arity is a valid Erlang
type test, otherwise false.
arith_op(OpName, Arity) -> bool()
Types:
OpName = atom()
Arity = integer()
Returns true if OpName/Arity is an arithmetic
operator, otherwise false.
bool_op(OpName, Arity) -> bool()
Types:
OpName = atom()
Arity = integer()
Returns true if OpName/Arity is a Boolean
operator, otherwise false.
comp_op(OpName, Arity) -> bool()
Types:
OpName = atom()
Arity = integer()
Returns true if OpName/Arity is a comparison
operator, otherwise false.
list_op(OpName, Arity) -> bool()
Types:
OpName = atom()
Arity = integer()
Returns true if OpName/Arity is a list
operator, otherwise false.
send_op(OpName, Arity) -> bool()
Types:
OpName = atom()
Arity = integer()
Returns true if OpName/Arity is a send
operator, otherwise false.
op_type(OpName, Arity) -> Type
Types:
OpName = atom()
Arity = integer()
Type = arith | bool | comp | list | send
Returns the Type of operator that OpName/Arity
belongs to,
or generates a function_clause error if it is not an
operator at all.
