.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This object describes the attachment of a elastic network interface
(\s-1ENI\s0) to an instance, and allows you to manipulate the attachment.
.PP
Please see VM::EC2::Generic for methods shared by all \s-1VM::EC2\s0
objects.
.SH "METHODS"
.IX Header "METHODS"
These object methods are supported:
.PP
.Vb 7
\& attachmentId          \-\- ID of the attachment
\& instanceId            \-\- ID of the instance
\& instanceOwnerId       \-\- ID of the owner of the instance
\& deviceIndex           \-\- Ethernet device number, e.g. "0" for eth0
\& status                \-\- Always "attached"; see below.
\& attachmentTime        \-\- Time this ENI was attached to the instance, as a DateTime
\& deleteOnTermination   \-\- If true, this ENI will be deleted when the instance terminates.
.Ve
.PP
Amazon does not document the network interface attachment object well,
and many of these fields are inferred by inspection of \s-1EC2 REST\s0
responses. In particular, the status field always seems to be
\&\*(L"attached\*(R", but there may be another state, such as \*(L"pending\*(R", which
is too short lived to be apparent.
.PP
In addition, this object supports the following convenience methods:
.PP
.Vb 1
\& instance    \-\- The VM::EC2::Instance to which the ENI is attached.
.Ve
.SH "STRING OVERLOADING"
.IX Header "STRING OVERLOADING"
When used in a string context, this object will be interpolated as the
attachmentId.
