|
value := scalar value |

|
| 151 |

\b |
| 152 |
|
where: |
| 153 |
|
* zero or more occurrences |

? zero or one occurrence |

|
[] grouping of expressions to be used with ? and * |
| 156 |

| 159 |
|
\b |
| 160 |
|
"AttrName" is the name of one attribute in the data type that defines the representation |
| 161 |
|
of the resource. The dot (".") character in "simpleFilterExpr" allows concatenation of |
| 162 |
|
<attrName> entries to filter by attributes deeper in the hierarchy of a structured document. |
| 163 |
|
"Op" stands for the comparison operator. If the expression has concatenated <attrName> |
| 164 |
|
entries, it means that the operator "op" is applied to the attribute addressed by the last |
| 165 |
|
<attrName> entry included in the concatenation. All simple filter expressions are combined |
| 166 |
|
by the "AND" logical operator. In a concatenation of <attrName> entries in a <simpleFilterExpr>, |
| 167 |
|
the rightmost "attrName" entry in a "simpleFilterExpr" is called "leaf attribute". The |
| 168 |
|
concatenation of all "attrName" entries except the leaf attribute is called the "attribute |
| 169 |
|
prefix". If an attribute referenced in an expression is an array, an object that contains a |
| 170 |
|
corresponding array shall be considered to match the expression if any of the elements in the |
| 171 |
|
array matches all expressions that have the same attribute prefix. |
| 172 |
|
|
| 173 |
|

--filter vim-account-id=<VIM_ACCOUNT_ID> |

--filter vdur.ip-address=<IP_ADDRESS> |
