CachedRange

Represents a ForwardRange (and a RandomAccessRange when possible) over the cached elements of a source range. Provides the range algorithm length() only if the source range does so.

struct CachedRange (

) {

~this();

Stats stats();

int opApply(int delegate(const(EC.ET)) func);

int opApply(int delegate(size_t, const(EC.ET)) func);

auto opIndex(size_t index);

static if(EC.rangeHasLength)

auto length();

}

Destructor

~this ~this(): Unregisters this slices from the actual ElementCache storage.

Postblit

this(this) this(this): Undocumented in source.

Members

Functions

empty auto empty(): Whether the range is empty
front auto front(): The front element of the range
length auto length(): Number of elements of this range
opApply int opApply(int delegate(const(EC.ET)) func)
int opApply(int delegate(size_t, const(EC.ET)) func): Support for foreach loops
opIndex auto opIndex(size_t index): Return a reference to an element
popFront void popFront(): Remove the front element from the range
save auto save(): Make and return a new ForwardRange object that is the equivalent of this range object
stats Stats stats(): Return statistics about the operation of ElementCache as well as the underlying CircularBlocks that it uses for element storage

Parameters

EC: the template instance of the ElementCache template that this range provides access to the elements of. The users are expected to call one of the cached functions, which sets this parameter automatically.
