std.range.interfaces.OutputRangeObject/outputRangeObject - multiple declarations

Class OutputRangeObject

Implements the OutputRange interface for all types E and wraps the put method for each type E in a virtual function.

class OutputRangeObject(R, E...) ;

Constructors

NameDescription
this (range)

Methods

NameDescription
factory (classname) Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
opCmp (o) Compare with another Object obj.
opEquals (o) Test whether this is equal to o. The default implementation only compares by identity (using the is operator). Generally, overrides and overloads for opEquals should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for null on the typed overload.
toHash () Compute hash function for Object.
toString () Convert Object to a human readable string.

Template outputRangeObject

Convenience function for creating an OutputRangeObject with a base range of type R that accepts types E.

template outputRangeObject(E...) ;

Contained Functions

NameDescription
outputRangeObject

Example

import std.array;
auto app = appender!(uint[])();
auto appWrapped = outputRangeObject!(uint, uint[])(app);
static assert(is(typeof(appWrapped) : OutputRange!(uint[])));
static assert(is(typeof(appWrapped) : OutputRange!(uint)));
