- path_relative_to
-
$rel_path = UR::Util::path_relative_to($base, $target);
Returns the pathname to $target relative to $base. If $base and $target are
the same, then it returns '.'. If $target is a subdirectory of of $base,
then it returns the portion of $target that is unique compared to $base.
If $target is not a subdirectory of $base, then it returns a relative
pathname starting with $base.
- generate_readwrite_methods
-
UR::Util->generate_readwrite_methods
(
some_scalar_property => 1,
some_array_property => []
);
This method generates accessor/set methods named after the keys of its hash
argument. The type of function generated depends on the default value
provided as the hash key value. If the hash key is a scalar, a scalar
method is generated. If the hash key is a reference to an array, an array
method is generated.
This method does not overwrite class methods that already exist.
- generate_readwrite_methods_override
-
UR::Util->generate_readwrite_methods_override
(
some_scalar_property => 1,
some_array_property => []
);
Same as generate_readwrite_function except that we force the functions into
the namespace even if the function is already defined
- generate_readonly_methods
-
UR::Util->generate_readonly_methods
(
some_scalar_property => 1,
some_array_property => []
);
This method generates accessor methods named after the keys of its hash
argument. The type of function generated depends on the default value
provided as the hash key value. If the hash key is a scalar, a scalar
method is generated. If the hash key is a reference to an array, an array
method is generated.
This method does not overwrite class methods that already exist.
- object
-
my $o = UR::Util::object($something);
Return the object form of the supplied argument. For regular objects, it
returns the argument unchanged. For singleton class names, it returns the
instance of the Singleton. For other class names, it throws an
exception.
- mapreduce_grep
-
my @matches = UR::Util->map_reduce_grep { shift->some_test } @candidates;
Works similar to the Perl "grep" builtin, but in a
possibly-parallel fashion. If the environment variable UR_NR_CPU is set to
a number greater than one, it will fork off child processes to perform the
test on slices of the input list, collect the results, and return the
matching items as a list.
The test function is called with a single argument, an item from the list to
be tested, and should return a true of false value.
NAME¶
UR::Util - Collection of utility subroutines and methods
DESCRIPTION¶
This package contains subroutines and methods used by other parts of the
infrastructure. These subs are not likely to be useful to outside code.
