Detailed Description

Extensions for System.Enum.

Member Function Documentation

static bool TriDevs.TriEngine.Extensions.EnumerationExtensions.Has< T > ( this Enum  value, T  check  )

static

Checks if an enumerated type contains a value.

Template Parameters

T	The enum type.

Parameters

value	The enum to check.
check	Value to check for.

Returns

True if the enum has the value(s), false otherwise.

        {
            Type type = value.GetType();

            //determine the values
            var parsed = new _Value(check, type);
            if (parsed.Signed.HasValue) //if (parsed.Signed is long)
            {
                return (Convert.ToInt64(value) & (long)parsed.Signed) == (long)parsed.Signed;
            }
            if (parsed.Unsigned.HasValue) //if (parsed.Unsigned is ulong)
            {
                return (Convert.ToUInt64(value) & (ulong)parsed.Unsigned) == (ulong)parsed.Unsigned;
            }
            return false;
        }

static T TriDevs.TriEngine.Extensions.EnumerationExtensions.Include< T > ( this Enum  value, T  append  )

static

Includes an enumerated type and returns the new value.

Template Parameters

T	The enum type.

Parameters

value	The enum to append to.
append	Value to append.

Returns

New enum T with the new values.

        {
            var type = value.GetType();

            //determine the values
            object result = value;
            var parsed = new _Value(append, type);
            if (parsed.Signed.HasValue) //if (parsed.Signed is long)
            {
                result = Convert.ToInt64(value) | (long)parsed.Signed;
            }
            else if (parsed.Unsigned.HasValue) //else if (parsed.Unsigned is ulong)
            {
                result = Convert.ToUInt64(value) | (ulong)parsed.Unsigned;
            }

            //return the final value
            return (T)Enum.Parse(type, result.ToString());
        }

static bool TriDevs.TriEngine.Extensions.EnumerationExtensions.Missing< T > ( this Enum  obj, T  value  )

static

Checks if an enumerated type is missing a value.

Template Parameters

T	The enum type.

Parameters

obj	The enum to check.
value	Value to check for.

Returns

True if the enum is missing the value(s), false otherwise.

        {
            return !Has(obj, value);
        }

static T TriDevs.TriEngine.Extensions.EnumerationExtensions.Remove< T > ( this Enum  value, T  remove  )

static

Removes an enumerated type and returns the new value.

Template Parameters

T	The enum type.

Parameters

value	The enum to remove from.
remove	Value to remove.

Returns

New enum T with the value(s) removed.

        {
            Type type = value.GetType();

            //determine the values
            object result = value;
            var parsed = new _Value(remove, type);
            if (parsed.Signed.HasValue) //if (parsed.Signed is long)
            {
                result = Convert.ToInt64(value) & ~(long)parsed.Signed;
            }
            else if (parsed.Unsigned.HasValue) //else if (parsed.Unsigned is ulong)
            {
                result = Convert.ToUInt64(value) & ~(ulong)parsed.Unsigned;
            }

            //return the final value
            return (T)Enum.Parse(type, result.ToString());
        }
