~~Title: Efl.Io.Reader: can_read,changed~~

===== Description =====

%%Notifies can_read property changed.%%

%%If %%[[:develop:api:efl:io:reader:property:can_read|Efl.Io.Reader.can_read]]%% is %%''true''%% there is data to %%[[:develop:api:efl:io:reader:method:read|Efl.Io.Reader.read]]%% without blocking/error. If %%[[:develop:api:efl:io:reader:property:can_read|Efl.Io.Reader.can_read]]%% is %%''false''%%, %%[[:develop:api:efl:io:reader:method:read|Efl.Io.Reader.read]]%% would either block or fail.%%

%%Note that usually this event is dispatched from inside %%[[:develop:api:efl:io:reader:method:read|Efl.Io.Reader.read]]%%, thus before it returns.%%
