question: a unique number that ensures the request ca n't be replayed . if the callerreference is new no matter the content of the cloudfrontoriginaccessidentityconfig object , a new origin access identity is created . if the callerreference is a value you already sent in a previous request to create an identity , and the content of the cloudfrontoriginaccessidentityconfig is identical to the original request ignoring white space , the response includes the same information returned to the original request . if the callerreference is a value you already sent in a previous request to create an identity but the content of the cloudfrontoriginaccessidentityconfig is different from the original request , cloudfront returns a cloudfrontoriginaccessidentityalreadyexists error . concode_field_sep String callerReference concode_elem_sep String comment concode_field_sep String getCallerReference concode_elem_sep CloudFrontOriginAccessIdentityConfig withComment concode_elem_sep CloudFrontOriginAccessIdentityConfig withCallerReference concode_elem_sep int hashCode concode_elem_sep boolean equals concode_elem_sep void setComment concode_elem_sep String getComment concode_elem_sep String toString
target: void function ( String arg0 ) { this . callerReference = arg0 ; }
