Class Expression
- All Implemented Interfaces:
Serializable
,SdkPojo
,ToCopyableBuilder<Expression.Builder,
Expression>
Use Expression
to filter in various Cost Explorer APIs.
Not all Expression
types are supported in each API. Refer to the documentation for each specific API to
see what is supported.
There are two patterns:
-
Simple dimension values.
-
There are three types of simple dimension values:
CostCategories
,Tags
, andDimensions
.-
Specify the
CostCategories
field to define a filter that acts on Cost Categories. -
Specify the
Tags
field to define a filter that acts on Cost Allocation Tags. -
Specify the
Dimensions
field to define a filter that acts on theDimensionValues
.
-
-
For each filter type, you can set the dimension name and values for the filters that you plan to use.
-
For example, you can filter for
REGION==us-east-1 OR REGION==us-west-1
. ForGetRightsizingRecommendation
, the Region is a full name (for example,REGION==US East (N. Virginia)
. -
The corresponding
Expression
for this example is as follows:{ "Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] } }
-
As shown in the previous example, lists of dimension values are combined with
OR
when applying the filter.
-
-
You can also set different match options to further control how the filter behaves. Not all APIs support match options. Refer to the documentation for each specific API to see what is supported.
-
For example, you can filter for linked account names that start with "a".
-
The corresponding
Expression
for this example is as follows:{ "Dimensions": { "Key": "LINKED_ACCOUNT_NAME", "MatchOptions": [ "STARTS_WITH" ], "Values": [ "a" ] } }
-
-
-
Compound
Expression
types with logical operations.-
You can use multiple
Expression
types and the logical operatorsAND/OR/NOT
to create a list of one or moreExpression
objects. By doing this, you can filter by more advanced options. -
For example, you can filter by
((REGION == us-east-1 OR REGION == us-west-1) OR (TAG.Type == Type1)) AND (USAGE_TYPE != DataTransfer)
. -
The corresponding
Expression
for this example is as follows:{ "And": [ {"Or": [ {"Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] }}, {"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 anExpression
object that creates an error:{ "And": [ ... ], "Dimensions": { "Key": "USAGE_TYPE", "Values": [ "DataTransfer" ] } }
The following is an example of the corresponding error message:
"Expression has more than one roots. Only one root operator is allowed for each expression: And, Or, Not, Dimensions, Tags, CostCategories"
-
For the GetRightsizingRecommendation
action, a combination of OR and NOT isn't supported. OR isn't
supported between different dimensions, or dimensions and tags. NOT operators aren't supported. Dimensions are also
limited to LINKED_ACCOUNT
, REGION
, or RIGHTSIZING_TYPE
.
For the GetReservationPurchaseRecommendation
action, only NOT is supported. AND and OR aren't supported.
Dimensions are limited to LINKED_ACCOUNT
.

Method Details
-
hasOr
public final boolean hasOr()For responses, this returns true if the service returned a value for the Or property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
or
Return results that match either
Dimension
object.Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasOr()
method.- Returns:
- Return results that match either
Dimension
object.
-
hasAnd
public final boolean hasAnd()For responses, this returns true if the service returned a value for the And property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
and
Return results that match both
Dimension
objects.Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasAnd()
method.- Returns:
- Return results that match both
Dimension
objects.
-
not
Return results that don't match a
Dimension
object.- Returns:
- Return results that don't match a
Dimension
object.

toBuilder
Description copied from interface:ToCopyableBuilder
Take this object and create a builder that contains all of the current property values of this object.- Specified by:

equalsBySdkFields
Description copied from interface:SdkPojo
Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
toString
Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value. -
