RefAppender

A version of Appender that can update an array in-place. It forwards all calls to an underlying appender implementation. Any calls made to the appender also update the pointer to the original array passed in.

Tip: Use the arrayPtr overload of appender for construction with type-inference.

struct RefAppender (

) if (

isDynamicArray!A

) {

this(A* arr);

void opDispatch(Args args);

void opOpAssign(U rhs);

size_t capacity [@property getter];

inout(ElementEncodingType!A)[] opSlice [@property getter];

}

Constructors

this this(A* arr): Constructs a RefAppender with a given array reference. This does not copy the data. If the array has a larger capacity as determined by arr.capacity, it will be used by the appender.

Members

Functions

opDispatch void opDispatch(Args args): Wraps remaining Appender methods such as put.
opOpAssign void opOpAssign(U rhs): Appends rhs to the managed array.

Properties

capacity size_t capacity [@property getter]: Returns the capacity of the array (the maximum number of elements the managed array can accommodate before triggering a reallocation). If any appending will reallocate, capacity returns 0.
opSlice inout(ElementEncodingType!A)[] opSlice [@property getter]

Parameters

A: The array type to simulate

Examples

int[] a = [1, 2];
auto app2 = appender(&a);
assert(app2[] == [1, 2]);
assert(a == [1, 2]);
app2 ~= 3;
app2 ~= [4, 5, 6];
assert(app2[] == [1, 2, 3, 4, 5, 6]);
assert(a == [1, 2, 3, 4, 5, 6]);

app2.reserve(5);
assert(app2.capacity >= 5);
