Event

An event structure representing a one-to-many function/delegate relationship. It mimics a function by overriding the call operator. It also implements the bidirectional range interface.

Destructor

~this ~this(): Undocumented in source.

Members

Aliases

ListenerType alias ListenerType = T: The listeners' type.
ParamTypes alias ParamTypes = ParameterTypeTuple!T: The event's argument type tuple.
ReturnType alias ReturnType = void: The event's return type.
ReturnType alias ReturnType = void: Undocumented in source.
ReturnType alias ReturnType = ReturnTypeTpl!T[]: Undocumented in source.

Functions

append void append(T[] listeners): Appends a listener to the listener collection.
back T back(): Get the last listener or throw an error if there are no listeners. Part of the bidirectional range interface.
call void call(ParamTypes params): Calls all the registered listeners in order.
clear void clear(): Clears all listeners.
empty bool empty(): A boolean property indicating whether there are listeners. Part of the bidirectional range interface.
front T front(): Get the first listener or throw an error if there are no listeners. Part of the bidirectional range interface.
listeners auto listeners(): A range array of all the listeners.
opCall void opCall(ParamTypes params): Aliases $(DDOC_PSYMBOL call).
opOpAssign void opOpAssign(T listener): Aliases $(DDOC_PSYMBOL append).
opOpAssign void opOpAssign(T listener): Aliases $(DDOC_PSYMBOL remove).
opSlice auto opSlice()
popBack void popBack(): Remove the last listener or throw an error if there are no listeners. Part of the bidirectional range interface.
popFront void popFront(): Remove the first listener or throw an error if there are no listeners. Part of the bidirectional range interface.
prepend void prepend(T[] listeners): Prepend listeners to the listener collection.
remove void remove(T[] listeners): Removed all occurrences of the given listeners.
save auto save(): Copies the event to allow multiple range-like iteration. Part of the bidirectional range interface.
size size_t size(): The number of listeners.
