mongo.regex: The mongo.regex class

In jonkatz2/rmongodb: R-MongoDB driver

Description

Objects of class "mongo.regex" represent regular expressions and are strings with the options value stored in the "options" attribute.

Details

See http://www.mongodb.org/display/DOCS/Advanced+Queries#AdvancedQueries-RegularExpressions

mongo.regex objects have "mongo.regex" as their class so that
mongo.bson.buffer.append() may detect them and append the appropriate BSON regex-typed value to a buffer.

These mongo.regex values may also be present in a list and will be handled properly
by mongo.bson.buffer.append.list() and mongo.bson.from.list().

Examples

buf <- mongo.bson.buffer.create()
regex <- mongo.regex.create("acme.*corp", options="i")
mongo.bson.buffer.append.regex(buf, "MatchAcme", regex)
b <- mongo.bson.from.buffer(buf)
