* @page eina_value_example_01_page Eina_Value usage
|
|
* @dontinclude eina_value_01.c
|
|
*
|
|
* This very simple example shows how to use some of the basic features of eina
|
|
* value: setting and getting values, converting between types and printing a
|
|
* value as a string.
|
|
*
|
|
* Our main function starts out with the basic, declaring some variables and
|
|
* initializing eina:
|
|
* @until eina_init
|
|
*
|
|
* Now we can jump into using eina value. We set a value, get this value and
|
|
* then print it:
|
|
* @until printf
|
|
*
|
|
* In the above snippet of code we printed an @c int value, we can however print
|
|
* the value as a string:
|
|
* @until free
|
|
*
|
|
* And once done with a value it's good practice to destroy it:
|
|
* @until eina_value_flush
|
|
*
|
|
* We now reuse @c v to store a string, get its value and print it:
|
|
* @until printf
|
|
* @note Since @c s is the value and not returned by @c eina_value_to_string()
|
|
* we don't need to free it.
|
|
*
|
|
* Just because we stored a string doesn't mean we can't use the @c
|
|
* eina_value_to_string() function, we can and it's important to note that it
|
|
* will return not the stored string but rather a copy of it(one we have to
|
|
* free):
|
|
* @until eina_value_flush
|
|
*
|
|
* And now to explore conversions between two type we'll create another value:
|
|
* @until eina_value_setup
|
|
*
|
|
* And make sure @c v and @c others have different types:
|
|
* @until eina_value_setup
|
|
*
|
|
* We then set a value to @c v and have it converted, to do this we don't need
|
|
* to tell to which type we want to convert, we just say were we want to store
|
|
* the converted value and eina value will figure out what to convert to, and
|
|
* how:
|
|
* @until eina_value_convert
|
|
*
|
|
* And now let's check the conversion worked:
|
|
* @until printf
|
|
*
|
|
* But converting to strings is not particularly exciting, @c
|
|
* eina_value_to_string() already did that, so now let's make the conversion the
|
|
* other way around, from string to @c int:
|
|
* @until printf
|
|
*
|
|
* And once done, destroy the values:
|
|
* @until }

/**
|
|
* @page eina_value_example_02_page Eina_Value struct usage
|
|
* @dontinclude eina_value_02.c
|
|
*
|
|
* This example will examine a hypothetical situation in which we had a
|
|
* structure(which represented parameters) with two fields, and then need to add
|
|
* a third field to our structure. If using structs directly we'd need to
|
|
* rewrite every piece of code that touches the struct, by using eina value, and
|
|
* thus having the compiler not even know the struct, we can reduce the amount
|
|
* of changes needed and retain interoperability between the old and new format.
|
|
*
|
|
* Our example will start with a function that creates descriptions of both of
|
|
* our structs for eina value usage. The first step is to create a struct and
|
|
* describe its members:
|
|
* @until v1_members[1]
|
|
* @note We can't pass the types of the members to EINA_VALUE_STRUCT_MEMBER
|
|
* macro because they are not constant initializers.
|
|
*
|
|
* So far it should be pretty easy to understand, we said @c My_Struct_V1 has
|
|
* two members, one of type @c int and another of type @c char. We now create
|
|
* the description of the actual struct, again nothing overly complex, we signal
|
|
* which version of EINA_VALUE_STRUCT we're using, we declare no special
|
|
* operations, our members and our size:
|
|
* @until V1_DESC
|
|
*
|
|
* We now repeat the process for the second version of our struct, the only
|
|
* difference is the addition of a third parameter of type @c int :
|
|
* @until V2_DESC
|
|
* @until }
|
|
*
|
|
* We'll now look at a function that sets the values of our structs. For
|
|
* simplicity's sake we initialize it we random values, a real world case would
|
|
* read these values from a file, a database or even from the network. The
|
|
* fundamental detail here is that this function works for both V1 and V2
|
|
* structs, this is because setting a parameter that a struct that doesn't have
|
|
* does nothing without throwing any errors:
|
|
* @until }
|
|
* @note While using eina_value_struct_set() with an in-existing parameter
|
|
* causes no error, it does return #EINA_FALSE, to notify it was not possible
|
|
* to set the value. This could be used to determine that we're handling a V1
|
|
* struct and take some action based on that.
|
|
*
|
|
* The next thing is to do is see what a function that uses the values of the
|
|
* struct looks like. We'll again be very simplistic in our usage, we'll just
|
|
* print the values, but a real world case, might send these values to another
|
|
* process use them to open a network/database connection or anything else.
|
|
* Since all versions of the struct have @c param1 and @c param2 we'll
|
|
* unconditionally use them:
|
|
* @until printf
|
|
*
|
|
* The next step is to conditionally use @c param3, which can fortunately be
|
|
* done in the same step in which we get it's value:
|
|
* @until }
|
|
*
|
|
* There we've now got functions that can both populate and use values from both
|
|
* our structs, so now let's actually use them in our main function by creating
|
|
* a struct of each type, initializing them and them using them:
|
|
* @until }
|
|
*
|
|
* This concludes our example. For the full source code see @ref
|
|
* eina_value_02_c.

/**
|
|
* @page eina_value_example_03_page Eina value custom type example
|
|
* @dontinclude eina_value_03.c
|
|
*
|
|
* For this example we'll be creating our own custom type of eina value. Eina
|
|
* value can already store struct timeval(man gettimeofday for more information)
|
|
* but it has no type to store struct timezone, so that's what this example will
|
|
* do.
|
|
* @note Struct timezone is actually obsolete, so using it in real world
|
|
* programs is probably not a good idea, but this is an example so, bear with
|
|
* us.
|
|
*
|
|
* To create our own custom eina value type we need to define functions to
|
|
* do the following operations on it:
|
|
* @li Setup
|
|
* @li Flush
|
|
* @li Copy
|
|
* @li Compare
|
|
* @li Set
|
|
* @li Get
|
|
* @li Conversion
|
|
*
|
|
* Most of this functions are very simple, so let's look at them, starting with
|
|
* setup which only clear the memory so that we can be certain we won't be using
|
|
* stale data:
|
|
* @until }
|
|
*
|
|
* Now the flush function, which is even simpler, it does nothing, that's
|
|
* because there is nothing we need to do, all the necessary steps are taken by
|
|
* eina value itself:
|
|
* @until }
|
|
*
|
|
* Our next function, copy, is a bit more interesting, but not much, it just
|
|
* casts our void pointers to struct timezone pointers and does the copy:
|
|
* @until }
|
|
* @note By now you might be wondering why our functions receive void pointers
|
|
* instead of pointers to struct timezone, and this is a good point. The reason
|
|
* for this is that eina value doesn't know anything about our type so it must
|
|
* use a generic void pointer, casting that pointer into a proper value is the
|
|
* job of the implementer of the new type.
|
|
*
|
|
* Next we have the comparison function, which compares the @c tz_minuteswest
|
|
* field of struct timezone, we don't compare @c tz_dsttime because that field
|
|
* is not used in linux:
|
|
* @until }
|
|
*
|
|
* Next we have setting, this however requires not one but rather two functions,
|
|
* the reason for this is because to be able to receive arguments of any type
|
|
* eina value uses <a href="https://wikipedia.org/wiki/Variadic_functions">
|
|
* variadic functions</a>, so we need a function to get the argument from a
|
|
* va_list and another to actually to the setting.
|
|
*
|
|
* Lets first look at the pset function which sets the received value to a
|
|
* pointer:
|
|
* @until }
|
|
*
|
|
* Next we have the vset function which get the argument from the va_list and
|
|
* passes it to the pset function:
|
|
* @until }
|
|
*
|
|
* And now the function to get the value, a very simple copying of the value to
|
|
* the given pointer:
|
|
* @until }
|
|
*
|
|
* And finally our conversion function, this is our longest and most interesting
|
|
* one. For numeric type we simply assign the value of @c tz_minuteswest to the
|
|
* new type and call a set function using it:
|
|
* @until EINA_VALUE_TYPE_DOUBLE
|
|
* @until return
|
|
* @note It would be a good idea to add checks for over and underflow for these
|
|
* types and return #EINA_FALSE in those cases, we omit this here for brevity.
|
|
*
|
|
* For string types we use @c snprintf() to format our @c tz_minuteswest field
|
|
* and put it in a string(again @c tz_dsttime is ignored because it's not used):
|
|
* @until }
|
|
*
|
|
* Finally we handle any other types by returning an error in that case:
|
|
* @until }
|
|
*
|
|
* Now that we have all the functions, we can populate an @c Eina_Value_Type to
|
|
* later use it with @c eina_value_setup():
|
|
* @until }
|
|
*
|
|
* We can now finally use our new TZ_TYPE with eina value, so lets conclude our
|
|
* example by practicing that by setting its value and printing it:
|
|
* @until }
|
|
*
