NAME
erl_internal - Internal Erlang Definitions
DESCRIPTION
This module defines Erlang BIFs, guard tests and operators. This module is only of interest to programmers who manipulate Erlang code.
EXPORTS
bif(Name, Arity) -> bool()
- 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.
