/**
*
* Use Expression to filter by cost or by usage. There are two patterns:
*
*
* -
*
* Simple dimension values - You can set the dimension name and values for the filters that you plan to use. For
* example, you can filter for INSTANCE_TYPE==m4.xlarge OR INSTANCE_TYPE==c4.large. The
* Expression for that looks like this:
*
*
* { "Dimensions": { "Key": "INSTANCE_TYPE", "Values": [ "m4.xlarge", “c4.large” ] } }
*
*
* The list of dimension values are OR'd together to retrieve cost or usage data. You can create Expression
* and DimensionValues objects using either with* methods or set* methods in
* multiple lines.
*
*
* -
*
* Compound dimension values with logical operations - You can use multiple Expression types and the
* logical operators AND/OR/NOT to create a list of one or more Expression objects. This
* allows you to filter on more advanced options. For example, you can filter on
* ((INSTANCE_TYPE == m4.large OR INSTANCE_TYPE == m3.large) OR (TAG.Type == Type1)) AND (USAGE_TYPE != DataTransfer)
* . The Expression for that looks like this:
*
*
* { "And": [ {"Or": [ {"Dimensions": { "Key": "INSTANCE_TYPE", "Values": [ "m4.x.large", "c4.large" ] }}, {"Tags": { "Key": "TagName", "Values": ["Value1"] } } ]}, {"Not": {"Dimensions": { "Key": "USAGE_TYPE", "Values": ["DataTransfer"] }}} ] }
*
*
*
* Because each Expression can have only one operator, the service returns an error if more than one is
* specified. The following example shows an Expression object that creates an error.
*
*
*
* { "And": [ ... ], "DimensionValues": { "Dimension": "USAGE_TYPE", "Values": [ "DataTransfer" ] } }
*
*
*
