Properties
The document's revision id. The revision id in the Document class is a constant while the revision id in the MutableDocument class is not. A newly created Document will have a null revision id. The revision id in a MutableDocument will be updated on save. The revision id format is opaque, which means its format has no meaning and shouldn't be parsed to get information.
The sequence number of the document in the database. The sequence number indicates how recently the document has been changed. Every time a document is updated, the database assigns it the next sequential sequence number. Thus, when a document's sequence number changes it means that the document been update (on-disk). If one document's sequence is different than another's, the document with the larger sequence number was changed more recently. Sequence numbers are not available for documents obtained from a replication filter. This method will always return 0 for such documents.
Functions
Tests whether a property exists or not. This can be less expensive than getValue(String), because it does not have to allocate an Object for the property value.
Gets a property's value as a boolean. Returns true if the value exists, and is either true
or a nonzero number.
Gets a property's value as a Date. JSON does not directly support dates, so the actual property value must be a string, which is then parsed according to the ISO-8601 date format (the default used in JSON.) Returns null if the value doesn't exist, is not a string, or is not parsable as a date. NOTE: This is not a generic date parser! It only recognizes the ISO-8601 format, with or without milliseconds.
Get a property's value as a Dictionary, which is a mapping object of a Dictionary value. Returns null if the property doesn't exist, or its value is not a Dictionary.
Gets a property's value as a double. Integers will be converted to double. The value true
is returned as 1.0, false
as 0.0. Returns 0.0 if the property doesn't exist or does not have a numeric value.
Gets a property's value as a float. Integers will be converted to float. The value true
is returned as 1.0, false
as 0.0. Returns 0.0 if the value doesn't exist or does not have a numeric value.
Gets a property's value as a long. Floating point values will be rounded. The value true
is returned as 1, false
as 0. Returns 0 if the value doesn't exist or does not have a numeric value.
Gets a property's value as an object. The object types are Blob, Array, Dictionary, Number, or String based on the underlying data type; or nil if the property value is null or the property doesn't exist.
Return a mutable copy of the document
