Data::Object::Code
Code Class for Perl 5
package main; use Data::Object::Code; my $code = Data::Object::Code->new(sub { $_[0] + 1 });
This package provides methods for manipulating code data.
This package inherits behaviors from:
Data::Object::Kind
This package integrates behaviors from:
Data::Object::Role::Dumpable
Data::Object::Role::Proxyable
Data::Object::Role::Throwable
This package uses type constraints from:
Data::Object::Types
This package implements the following methods:
call(Any $arg1) : Any
The call method executes and returns the result of the code.
my $code = Data::Object::Code->new(sub { ($_[0] // 0) + 1 }); $code->call; # 1
my $code = Data::Object::Code->new(sub { ($_[0] // 0) + 1 }); $code->call(0); # 1
my $code = Data::Object::Code->new(sub { ($_[0] // 0) + 1 }); $code->call(1); # 2
my $code = Data::Object::Code->new(sub { ($_[0] // 0) + 1 }); $code->call(2); # 3
compose(CodeRef $arg1, Any $arg2) : CodeLike
The compose method creates a code reference which executes the first argument (another code reference) using the result from executing the code as it's argument, and returns a code reference which executes the created code reference passing it the remaining arguments when executed.
my $code = Data::Object::Code->new(sub { [@_] }); $code->compose($code, 1,2,3); # $code->(4,5,6); # [[1,2,3,4,5,6]]
conjoin(CodeRef $arg1) : CodeLike
The conjoin method creates a code reference which execute the code and the argument in a logical AND operation having the code as the lvalue and the argument as the rvalue.
my $code = Data::Object::Code->new(sub { $_[0] % 2 }); $code = $code->conjoin(sub { 1 }); # $code->(0); # 0 # $code->(1); # 1 # $code->(2); # 0 # $code->(3); # 1 # $code->(4); # 0
curry(CodeRef $arg1) : CodeLike
The curry method returns a code reference which executes the code passing it the arguments and any additional parameters when executed.
my $code = Data::Object::Code->new(sub { [@_] }); $code = $code->curry(1,2,3); # $code->(4,5,6); # [1,2,3,4,5,6]
defined() : Num
The defined method returns true if the object represents a value that meets the criteria for being defined, otherwise it returns false.
my $code = Data::Object::Code->new; $code->defined; # 1
disjoin(CodeRef $arg1) : CodeRef
The disjoin method creates a code reference which execute the code and the argument in a logical OR operation having the code as the lvalue and the argument as the rvalue.
my $code = Data::Object::Code->new(sub { $_[0] % 2 }); $code = $code->disjoin(sub { -1 }); # $code->(0); # -1 # $code->(1); # 1 # $code->(2); # -1 # $code->(3); # 1 # $code->(4); # -1
next(Any $arg1) : Any
The next method is an alias to the call method. The naming is especially useful (i.e. helps with readability) when used with closure-based iterators.
my $code = Data::Object::Code->new(sub { $_[0] * 2 }); $code->next(72); # 144
rcurry(Any $arg1) : CodeLike
The rcurry method returns a code reference which executes the code passing it the any additional parameters and any arguments when executed.
my $code = Data::Object::Code->new(sub { [@_] }); $code = $code->rcurry(1,2,3); # $code->(4,5,6); # [4,5,6,1,2,3]
