public class DescribeInstancesAction {
/**
* Describes one or more instances.
* Note: If you specify one or more instance IDs, Amazon EC2 returns information for those instances.
* If you do not specify instance IDs, Amazon EC2 returns information for all relevant instances.
* If you specify an instance that you do not own, it's not included in the output.
* Recently terminated instances might appear in the output. This interval is usually less than one hour.
*
* @param endpoint Endpoint to which request will be sent.
* Default: "https://ec2.amazonaws.com"
* @param identity ID of the secret access key associated with your Amazon AWS or IAM account.
* Example: "AKIAIOSFODNN7EXAMPLE"
* @param credential Secret access key associated with your Amazon AWS or IAM account.
* Example: "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
* @param proxyHost Optional - proxy server used to connect to Amazon API. If empty no proxy
* will be used.
* Default: ""
* @param proxyPort Optional - proxy server port. You must either specify values for both
* proxyHost and proxyPort inputs or leave them both empty.
* Default: ""
* @param proxyUsername Optional - proxy server user name.
* Default: ""
* @param proxyPassword Optional - proxy server password associated with the proxyUsername
* input value.
* Default: ""
* @param headers Optional - string containing the headers to use for the request separated
* by new line (CRLF). The header name-value pair will be separated by ":".
* Format: Conforming with HTTP standard for headers (RFC 2616)
* Examples: "Accept:text/plain"
* Default: ""
* @param queryParams Optional - string containing query parameters that will be appended to
* the URL. The names and the values must not be URL encoded because if
* they are encoded then a double encoded will occur. The separator between
* name-value pairs is "&" symbol. The query name will be separated from
* query value by "=".
* Examples: "parameterName1=parameterValue1¶meterName2=parameterValue2"
* Default: ""
* @param version Version of the web service to made the call against it.
* Example: "2016-11-15"
* Default: "2016-11-15"
* @param delimiter Optional - Delimiter that will be used.
* @param filterNamesString Optional - String that contains one or more values that represents filters for the search.
* For a complete list of valid filters see: http://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstances.html
* Example: "instance-type,block-device-mapping.status,block-device-mapping.delete-on-termination"
* Default: ""
* @param filterValuesString Optional - String that contains one or more values that represents filters values.
* For a complete list of valid filters see: http://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstances.html
* Example of filters values for the above filterNamesString input: "m1.small|m1.large,attached,true"
* Note that "m1.small|m1.large" represents values for "instance-type" and are separated
* by the enforced "|" symbol
* Default (describes all your instances): ""
* @param instanceIdsString Optional - String that contains one or more values that represents instance IDs.
* Example: "i-12345678,i-abcdef12,i-12ab34cd"
* Default: ""
* @param maxResults Optional - The maximum number of results to return in a single call. To retrieve the
* remaining results, make another call with the returned NextToken value. This value can
* be between 5 and 1000. You cannot specify this parameter and the instance IDs parameter
* or tag filters in the same call.
* Default: ""
* @param nextToken Optional - The token to use to retrieve the next page of results. This value is null when
* there are no more results to return.
* Default: ""
* @return A map with strings as keys and strings as values that contains: outcome of the action, returnCode of the
* operation, or failure message and the exception if there is one
