# File lib/bson/int32.rb, line 48
def self.from_bson(buffer)
  buffer.get_int32
end
new(integer) click to toggle source

Instantiate a BSON Int32.

@param [ Integer ] integer The 32-bit integer.

@see bsonspec.org/#/specification

end

Public Instance Methods

==(other) click to toggle source

Check equality of the int32 with another object.

@param [ Object ] other The object to check against.

@return [ true, false ] If the objects are equal.

@since 4.4.0

# File lib/bson/int32.rb, line 99
def ==(other)
  return false unless other.is_a?(Int32)
  @integer == other.instance_variable_get('@integer')

Also aliased as: eql?, ===

to_bson(buffer = ByteBuffer.new, validating_keys = Config.validating_keys?) click to toggle source

Append the integer as encoded BSON to a ByteBuffer.

@example Encoded the integer and append to a ByteBuffer.

int32.to_bson

@return [ BSON::ByteBuffer ] The buffer with the encoded integer.

@see bsonspec.org/#/specification

@since 4.2.0

# File lib/bson/int32.rb, line 74
def to_bson(buffer = ByteBuffer.new, validating_keys = Config.validating_keys?)
  buffer.put_int32(@integer)
end
to_bson_key(validating_keys = Config.validating_keys?) click to toggle source

Convert the integer to a BSON string key.

@example Convert the integer to a BSON key string.

int.to_bson_key

@param [ true, false ] validating_keys If BSON should validate the key.

@return [ String ] The string key.
