Returns an array containing the values associated with the given keys.
Returns true if specified value
is found in the database.
Creates a class to wrap the C struct with the value ty
See also Fiddle::Importer.struct
Returns a new instance of the C struct with the value ty
at the addr
address.
Fills the buffer from the underlying SSLSocket
Returns an Array
of individual raw profile data Hashes ordered from earliest to latest by :GC_INVOKE_TIME
.
For example:
[ { :GC_TIME=>1.3000000000000858e-05, :GC_INVOKE_TIME=>0.010634999999999999, :HEAP_USE_SIZE=>289640, :HEAP_TOTAL_SIZE=>588960, :HEAP_TOTAL_OBJECTS=>14724, :GC_IS_MARKED=>false }, # ... ]
The keys mean:
:GC_TIME
:GC_INVOKE_TIME
Time
elapsed in seconds from startup to when the GC
was invoked
:HEAP_USE_SIZE
Total bytes of heap used
:HEAP_TOTAL_SIZE
Total size of heap in bytes
:HEAP_TOTAL_OBJECTS
Total number of objects
:GC_IS_MARKED
Returns true
if the GC
is in mark phase
If ruby was built with GC_PROFILE_MORE_DETAIL
, you will also have access to the following hash keys:
:GC_MARK_TIME
:GC_SWEEP_TIME
:ALLOCATE_INCREASE
:ALLOCATE_LIMIT
:HEAP_USE_PAGES
:HEAP_LIVE_OBJECTS
:HEAP_FREE_OBJECTS
:HAVE_FINALIZE
A wrapper class to use a StringIO
object as the body and switch to a TempFile when the passed threshold is passed. Initialize the data from the query.
Handles multipart forms (in particular, forms that involve file uploads). Reads query parameters in the @params field, and cookies into @cookies.
Iterates through header values, passing each value to the code block.
Returns an enumerator if no block is given.
This code is based directly on the Text
gem implementation Returns a value representing the “cost” of transforming str1 into str2
Displays an error statement
to the error output location. Asks a question
if given.
Displays a warning statement
to the warning output location. Asks a question
if given.
Creates and pushes the initial state for the resolution, based upon the {#requested} dependencies @return [void]
Returns the concatenated string from strings
.
Tags the current state of the dependency as the given tag @param [Object] tag an opaque tag for the current state of the graph @return [Void]
Returns the value of the given instance variable, or nil if the instance variable is not set. The @
part of the variable name should be included for regular instance variables. Throws a NameError
exception if the supplied symbol is not valid as an instance variable name. String
arguments are converted to symbols.
class Fred def initialize(p1, p2) @a, @b = p1, p2 end end fred = Fred.new('cat', 99) fred.instance_variable_get(:@a) #=> "cat" fred.instance_variable_get("@b") #=> 99
Sets the instance variable named by symbol to the given object. This may circumvent the encapsulation intended by the author of the class, so it should be used with care. The variable does not have to exist prior to this call. If the instance variable name is passed as a string, that string is converted to a symbol.
class Fred def initialize(p1, p2) @a, @b = p1, p2 end end fred = Fred.new('cat', 99) fred.instance_variable_set(:@a, 'dog') #=> "dog" fred.instance_variable_set(:@c, 'cat') #=> "cat" fred.inspect #=> "#<Fred:0x401b3da8 @a=\"dog\", @b=99, @c=\"cat\">"
Returns true
if the given instance variable is defined in obj. String
arguments are converted to symbols.
class Fred def initialize(p1, p2) @a, @b = p1, p2 end end fred = Fred.new('cat', 99) fred.instance_variable_defined?(:@a) #=> true fred.instance_variable_defined?("@b") #=> true fred.instance_variable_defined?("@c") #=> false
Removes the named instance variable from obj, returning that variable’s value. String
arguments are converted to symbols.
class Dummy attr_reader :var def initialize @var = 99 end def remove remove_instance_variable(:@var) end end d = Dummy.new d.var #=> 99 d.remove #=> 99 d.var #=> nil
