Results for: "Logger"

Display an informational alert. Will ask question if it is not nil.

Returns the parser to be used.

Unless a URI::Parser is defined, DEFAULT_PARSER is used.

Sets userinfo, argument is string like ‘name:pass’.

Args

v

String

Description

Public setter for the user component (with validation).

See also URI::Generic.check_user.

Usage

require 'uri'

uri = URI.parse("http://john:S3nsit1ve@my.example.com")
uri.user = "sam"
uri.to_s  #=> "http://sam:V3ry_S3nsit1ve@my.example.com"

Returns the userinfo, either as ‘user’ or ‘user:password’.

Returns the user component.

Args

v

String

Description

Public setter for the query component v.

Usage

require 'uri'

uri = URI.parse("http://my.example.com/?id=25")
uri.query = "id=1"
uri.to_s  #=> "http://my.example.com/?id=1"

Returns true if URI is hierarchical.

Description

URI has components listed in order of decreasing significance from left to right, see RFC3986 tools.ietf.org/html/rfc3986 1.2.3.

Usage

require 'uri'

uri = URI.parse("http://my.example.com/")
uri.hierarchical?
#=> true
uri = URI.parse("mailto:joe@example.com")
uri.hierarchical?
#=> false

Args

v

URI or String

Description

Attempts to parse other URI oth, returns [parsed_oth, self].

Usage

require 'uri'

uri = URI.parse("http://my.example.com")
uri.coerce("http://foo.com")
#=> [#<URI::HTTP http://foo.com>, #<URI::HTTP http://my.example.com>]

Returns filter.

Setter for filter val.

Checks if URI has a path. For URI::LDAP this will return false.

Setter for headers v.

Returns a Hash (not a DBM database) created by using each value in the database as a key, with the corresponding key as its value.

Note that all values in the hash will be Strings, but the keys will be actual objects.

Returns the number of the signal that caused stat to terminate (or nil if self was not terminated by an uncaught signal).

Returns true if this lock is currently held by some thread.

Attempts to grab the lock and waits if it isn’t available. Raises ThreadError if mutex was locked by the current thread.

Releases the lock. Raises ThreadError if mutex wasn’t locked by the current thread.

Closes the queue. A closed queue cannot be re-opened.

After the call to close completes, the following are true:

• closed? will return true

• close will be ignored.

• calling enq/push/<< will raise a ClosedQueueError.

• when empty? is false, calling deq/pop/shift will return an object from the queue as usual.

• when empty? is true, deq(false) will not suspend the thread and will return nil. deq(true) will raise a ThreadError.

ClosedQueueError is inherited from StopIteration, so that you can break loop block.

Example:

q = Thread::Queue.new
Thread.new{
  while e = q.deq # wait for nil to break loop
    # ...
  end
}
q.close

Returns true if the queue is closed.

Similar to Thread::Queue#close.

The difference is behavior with waiting enqueuing threads.

If there are waiting enqueuing threads, they are interrupted by raising ClosedQueueError(‘queue closed’).

Convert source_string and return destination_string.

source_string is assumed as a part of source. i.e. :partial_input=>true is specified internally. finish method should be used last.

ec = Encoding::Converter.new("utf-8", "euc-jp")
puts ec.convert("\u3042").dump     #=> "\xA4\xA2"
puts ec.finish.dump                #=> ""

ec = Encoding::Converter.new("euc-jp", "utf-8")
puts ec.convert("\xA4").dump       #=> ""
puts ec.convert("\xA2").dump       #=> "\xE3\x81\x82"
puts ec.finish.dump                #=> ""

ec = Encoding::Converter.new("utf-8", "iso-2022-jp")
puts ec.convert("\xE3").dump       #=> "".force_encoding("ISO-2022-JP")
puts ec.convert("\x81").dump       #=> "".force_encoding("ISO-2022-JP")
puts ec.convert("\x82").dump       #=> "\e$B$\"".force_encoding("ISO-2022-JP")
puts ec.finish.dump                #=> "\e(B".force_encoding("ISO-2022-JP")

If a conversion error occur, Encoding::UndefinedConversionError or Encoding::InvalidByteSequenceError is raised. Encoding::Converter#convert doesn’t supply methods to recover or restart from these exceptions. When you want to handle these conversion errors, use Encoding::Converter#primitive_convert.

If none is given, returns the resulting hash value of the digest, keeping the digest’s state.

If a string is given, returns the hash value for the given string, resetting the digest to the initial state before and after the process.
