Value-objects

Numeric value-objects

Int

Integer numbers without a fractional component that don't support decimal points.

from pyvalueobjects import Int

# Creation
my_integer = Int(9)

# Getting raw value
my_integer.value() # returns -> 9

Nullable Int

Integer numbers and None.

from pyvalueobjects import NullableInt

# Creation
my_integer = NullableInt(9)

# Creating from None
my_nullable_integer = NullableInt(None)

# Getting raw value
my_integer.value() # returns -> 9
my_nullable_integer.value() # returns -> None

String value-objects

String

from pyvalueobjects import String

# Creation
my_str = String('potato')

# Getting raw value
my_str.value() # returns -> 'potato'

Nullable String

from pyvalueobjects import NullableString

# Creation
my_str = NullableString('potato')

# Getting raw value
my_str.value() # returns -> 'potato'

# Creation
my_nullable_str = NullableString(None)

# Getting raw value
my_nullable_str.value() # returns -> None

Non Empty String

from pyvalueobjects import NonEmptyString

# Creation
my_str = NonEmptyString('potato')

# Getting raw value
my_str.value() # returns -> 'potato'

# Creation
my_str2 = NonEmptyString('') # raises error

Nullable non Empty String

from pyvalueobjects import NullableNonEmptyString

# Creation
my_str = NullableNonEmptyString('potato')

# Getting raw value
my_str.value() # returns -> 'potato'

# Creation
my_str2 = NullableNonEmptyString(None)

# Getting raw value
my_str2.value() # returns -> None

# Creation
my_str3 = NullableNonEmptyString('') # raises error

Uuid4

from pyvalueobjects import Uuid4

# Creation
my_uuid4 = Uuid4('6c7add12-bf35-459e-a6c5-3178a2a33011')

# Getting raw value
my_uuid4.value()  # returns -> '6c7add12-bf35-459e-a6c5-3178a2a33011'

Nullable Uuid4

from pyvalueobjects import NullableUuid4

# Creation
my_uuid4 = NullableUuid4('6c7add12-bf35-459e-a6c5-3178a2a33011')
my_null_uuid4 = NullableUuid4(None)

# Getting raw value
my_uuid4.value()  # returns -> '6c7add12-bf35-459e-a6c5-3178a2a33011'
my_null_uuid4.value()  # returns -> 'None'

Date value-objects

ISO Date

from pyvalueobjects import IsoDate

# Creation
my_date = IsoDate('2023-08-15T04:55:12.076Z')

# Getting raw value
my_date.value()  # returns -> '2023-08-15T04:55:12.076Z'

Security value-objects

CVE

from pyvalueobjects import Cve

# Creation
my_cve = Cve('CVE-2014-9418')

# Getting raw value
my_cve.value()  # returns -> 'CVE-2014-9418'

Nullable CVE

from pyvalueobjects import NullableCve

# Creation
my_cve = NullableCve('CVE-2014-9418')
my_null_cve = NullableCve(None)

# Getting raw value
my_cve.value()  # returns -> 'CVE-2014-9418'
my_null_cve.value()  # returns -> None

CPE

from pyvalueobjects import Cpe

# Creation
my_cpe = Cpe('cpe:/a:openjdk:openjdk:8u282')

# Getting raw value
my_cpe.value()  # returns -> 'cpe:/a:openjdk:openjdk:8u282'
