Releases the lock and sleeps timeout seconds if it is given and non-nil or forever. Raises ThreadError if mutex wasn’t locked by the current thread.
When the thread is next woken up, it will attempt to reacquire the lock.
Note that this method can wakeup without explicit Thread#wakeup call. For example, receiving signal and so on.
Returns the slept time in seconds if woken up, or nil if timed out.
Removes all objects from the queue.
Returns the length of the queue.
Removes all objects from the queue.
Returns the length of the queue.
Deletes the entry for the given key and returns its associated value.
If no block is given and key is found, deletes the entry and returns the associated value:
m = ObjectSpace::WeakMap.new key = "foo" m[key] = 1 m.delete(key) # => 1 m[key] # => nil
If no block is given and key is not found, returns nil.
If a block is given and key is found, ignores the block, deletes the entry, and returns the associated value:
m = ObjectSpace::WeakMap.new key = "foo" m[key] = 2 m.delete(key) { |key| raise 'Will never happen'} # => 2
If a block is given and key is not found, yields the key to the block and returns the block’s return value:
m = ObjectSpace::WeakMap.new m.delete("nosuch") { |key| "Key #{key} not found" } # => "Key nosuch not found"
Returns the number of referenced objects
Deletes the entry for the given key and returns its associated value.
If no block is given and key is found, deletes the entry and returns the associated value:
m = ObjectSpace::WeakKeyMap.new key = "foo" # to hold reference to the key m[key] = 1 m.delete("foo") # => 1 m["foo"] # => nil
If no block given and key is not found, returns nil.
If a block is given and key is found, ignores the block, deletes the entry, and returns the associated value:
m = ObjectSpace::WeakKeyMap.new key = "foo" # to hold reference to the key m[key] = 2 m.delete("foo") { |key| raise 'Will never happen'} # => 2
If a block is given and key is not found, yields the key to the block and returns the block’s return value:
m = ObjectSpace::WeakKeyMap.new m.delete("nosuch") { |key| "Key #{key} not found" } # => "Key nosuch not found"
Removes all map entries; returns self.
Escape only the tags of certain HTML elements in string.
Takes an element or elements or array of elements. Each element is specified by the name of the element, without angle brackets. This matches both the start and the end tag of that element. The attribute list of the open tag will also be escaped (for instance, the double-quotes surrounding attribute values).
print CGI.escapeElement('<BR><A HREF="url"></A>', "A", "IMG") # "<BR><A HREF="url"></A>" print CGI.escapeElement('<BR><A HREF="url"></A>', ["A", "IMG"]) # "<BR><A HREF="url"></A>"
Returns digest_obj.digest_length().
Updates the digest with the contents of a given file name and returns self.
The Fiddle::CompositeHandler instance
Will raise an error if no handlers are open.
Decodes a BER- or DER-encoded value and creates an ASN1Data instance. der may be a String or any object that features a .to_der method transforming it into a BER-/DER-encoded String+
der = File.binread('asn1data') asn1 = OpenSSL::ASN1.decode(der)
Removes the header for the given case-insensitive key (see Fields); returns the deleted value, or nil if no such field exists:
req = Net::HTTP::Get.new(uri) req.delete('Accept') # => ["*/*"] req.delete('Nosuch') # => nil
NOTE: This means Fiddle and curses are enabled.
Return true if RJIT is enabled.
Start JIT compilation after --rjit-disable.
