Attributes

db_type [RW]

The type of this multirange (e.g. ‘int4multirange’).

Public Class methods

new(ranges, db_type)

Set the array of ranges to delegate to, and the database type.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
266 def initialize(ranges, db_type)
267   super(ranges)
268   @db_type = db_type.to_s
269 end

Public Instance methods

==(other)

Don’t consider multiranges with different database types equal.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
309 def ==(other)
310   return false if PGMultiRange === other && other.db_type != db_type
311   super
312 end
cover?(value)

Return whether the value is inside any of the ranges in the multirange.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
294 def cover?(value)
295   any?{|range| range.cover?(value)}
296 end
eql?(other)

Don’t consider multiranges with different database types equal.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
300 def eql?(other)
301   if PGMultiRange === other
302     return false unless other.db_type == db_type
303     other = other.__getobj__
304   end
305   __getobj__.eql?(other)
306 end
op()

Wrap the PGRange instance in an RangeOp, allowing you to easily use the PostgreSQL range functions and operators with literal ranges.

[show source] 
    # File lib/sequel/extensions/pg_range_ops.rb
153 def op
154   RangeOp.new(self)
155 end
sequel_auto_param_type(ds)

Allow automatic parameterization.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
341 def sequel_auto_param_type(ds)
342   "::#{db_type}"
343 end
sql_literal_append(ds, sql)

Append the multirange SQL to the given sql string.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
272 def sql_literal_append(ds, sql)
273   sql << db_type << '('
274   joiner = nil
275   conversion_meth = nil
276   each do |range|
277     if joiner
278       sql << joiner
279     else
280       joiner = ', '
281     end
282 
283     unless range.is_a?(PGRange)
284       conversion_meth ||= :"typecast_value_#{db_type.sub('multi', '')}"
285       range = ds.db.send(conversion_meth, range)
286     end
287 
288     ds.literal_append(sql, range)
289   end
290   sql << ')'
291 end
unquoted_literal(ds)

Return a string containing the unescaped version of the multirange. Separated out for use by the bound argument code.

[show source] 
    # File lib/sequel/extensions/pg_multirange.rb
316 def unquoted_literal(ds)
317   val = String.new
318   val << "{"
319 
320   joiner = nil
321   conversion_meth = nil
322   each do |range|
323     if joiner
324       val << joiner
325     else
326       joiner = ', '
327     end
328 
329     unless range.is_a?(PGRange)
330       conversion_meth ||= :"typecast_value_#{db_type.sub('multi', '')}"
331       range = ds.db.send(conversion_meth, range)
332     end
333 
334     val << range.unquoted_literal(ds)
335   end
336    
337   val << "}"
