IEnum

Interface defining the basic functionality of an enum class.

interface IEnum {

alias Name = istring;

alias Value = int;

Name* opIn_r(Value v);

Value* opIn_r(Name n);

alias opBinaryRight(istring op : "in") = opIn_r;

Name opIndex(Value v);

Value opIndex(Name n);

size_t length();

int opApply(int delegate(ref const(Name) name, ref const(Value) value) dg);

int opApply(int delegate(ref size_t i, ref const(Name) name, ref const(Value) value) dg);

}

Members

Aliases

Name alias Name = istring: Aliases for the types of an enum class' names & values.
Value alias Value = int: Undocumented in source.
opBinaryRight alias opBinaryRight(istring op : "in") = opIn_r: Support for the 'in' operator

Functions

length size_t length()
max Value max()
min Value min()
opApply int opApply(int delegate(ref const(Name) name, ref const(Value) value) dg): foreach iteration over the names and values in the enum.
opApply int opApply(int delegate(ref size_t i, ref const(Name) name, ref const(Value) value) dg): foreach iteration over the names and values in the enum and their indices.
opIn_r Name* opIn_r(Value v): Looks up an enum member's name from its value.
opIn_r Value* opIn_r(Name n): Looks up an enum member's value from its name.
opIndex Name opIndex(Value v): Looks up an enum member's name from its value, using opIndex.
opIndex Value opIndex(Name n): Looks up an enum member's value from its name, using opIndex.
