Method: OCI8::OracleVersion#initialize

Defined in:
lib/oci8/oracle_version.rb

#initialize(arg, minor = nil, update = nil, patch = nil, port_update = nil) ⇒ OCI8::OracleVersion

Creates an OCI8::OracleVersion object.

If the first argument arg is a String, it is parsed as dotted version string. If it is bigger than 0x08000000, it is parsed as a number contains 5-digit Oracle version. Otherwise, it is used as a major version and the rest arguments are minor, update, patch and port_update. Unspecified version numbers are zeros by default.

Examples:

# When the first argument is a String,
oraver = OCI8::OracleVersion.new('11.2.0.3')
oraver.major       # => 11
oraver.minor       # =>  2
oraver.update      # =>  0
oraver.patch       # =>  3
oraver.port_update # =>  0

# When the first argument is bigger than 0x08000000,
oraver = OCI8::OracleVersion.new(0x0b200300)
oraver.major       # => 11
oraver.minor       # =>  2
oraver.update      # =>  0
oraver.patch       # =>  3
oraver.port_update # =>  0

# Otherwise,
oraver = OCI8::OracleVersion.new(11, 2, 0, 3)
oraver.major       # => 11
oraver.minor       # =>  2
oraver.update      # =>  0
oraver.patch       # =>  3
oraver.port_update # =>  0
