This class is used to create State instances, that are use to hold data while unparsing a Ruby data structure into a JSON string.

Methods

forget   from_state   new   remember   seen?  

Attributes

array_nl  [RW]  This string is put at the end of a line that holds a JSON array.
indent  [RW]  This string is used to indent levels in the JSON string.
object_nl  [RW]  This string is put at the end of a line that holds a JSON object (or Hash).
space  [RW]  This string is used to include a space between the tokens in a JSON string.

Public Class methods

from_state(opts)

Creates a State object from opts, which ought to be Hash to create a new State instance configured by opts, something else to create an unconfigured instance. If opts is a State object, it is just returned.

Public Instance methods

forget(object)

Forget object for this Unparsing run.

     # File lib/json.rb, line 432
432:     def forget(object)
433:       @seen.delete object.__id__
434:     end
remember(object)

Remember object, to find out if it was already encountered (to find out if a cyclic data structure is unparsed).

[Source]

     # File lib/json.rb, line 427
427:     def remember(object)
428:       @seen[object.__id__] = true
429:     end
seen?(object)

Returns true, if object was already seen during this Unparsing run.

[Source]

     # File lib/json.rb, line 421
421:     def seen?(object)
422:       @seen.key?(object.__id__)
423:     end
