erl_internal(3erl) Erlang Module Definition erl_internal(3erl) 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.
