If *isValue* is `False` then this object represents just ASN.1 schema. If *isValue* is `True` then, in addition to its ASN.1 schema features, this object can also be used like a Python built-in object (e.g. `int`, `str`, `dict` etc.). Returns ------- : :class:`bool` :class:`False` if object represents just ASN.1 schema. :class:`True` if object represents ASN.1 schema and can be used as a normal value. Note ---- There is an important distinction between PyASN1 schema and value objects. The PyASN1 schema objects can only participate in ASN.1 schema-related operations (e.g. defining or testing the structure of the data). Most obvious uses of ASN.1 schema is to guide serialisation codecs whilst encoding/decoding serialised ASN.1 contents. The PyASN1 value objects can **additionally** participate in many operations involving regular Python objects (e.g. arithmetic, comprehension etc). )rn r0 r' r r r r9 ' s z AbstractSimpleAsn1Item.isValuec K s8 |t kr|s| S | j}| j�� }|�|� | j|f|�S )a` Create a modified version of |ASN.1| schema or value object.

The subtype relationship between ASN.1 types has no correlation with subtype relationship between Python types. ASN.1 type is mainly identified by its tag(s) (:py:class:`~pyasn1.type.tag.TagSet`) and value range constraints (:py:class:`~pyasn1.type.constraint.ConstraintsIntersection`). These ASN.1 type properties are implemented as |ASN.1| attributes. The `subtype()` method accepts the same set arguments as |ASN.1| class takes on instantiation except that all parameters of the `subtype()` method are optional. With the exception of the arguments described below, the rest of supplied arguments they are used to create a copy of `self` taking precedence over the ones used to instantiate `self`. The following arguments to `subtype()` create a ASN.1 subtype out of |ASN.1| type: Other Parameters ---------------- implicitTag: :py:class:`~pyasn1.type.tag.Tag` Implicitly apply given ASN.1 tag object to `self`'s :py:class:`~pyasn1.type.tag.TagSet`, then use the result as new object's ASN.1 tag(s). explicitTag: :py:class:`~pyasn1.type.tag.Tag` Explicitly apply given ASN.1 tag object to `self`'s :py:class:`~pyasn1.type.tag.TagSet`, then use the result as new object's ASN.1 tag(s). subtypeSpec: :py:class:`~pyasn1.type.constraint.ConstraintsIntersection` Add ASN.1 constraints object to one of the `self`'s, then use the result as new object's ASN.1 constraints.
