public static final class QueryHeader.Builder extends com.google.protobuf.GeneratedMessageLite.Builder<QueryHeader,QueryHeader.Builder> implements QueryHeaderOrBuilder
 *
 A standard query header.<br/>
 Each query from the client to the node must contain a QueryHeader, which
 specifies the desired response type, and includes a payment transaction
 that will compensate the network for responding to the query.
 The payment may be blank if the query is free.

 The payment transaction MUST be a `cryptoTransfer` from the payer account
 to the account of the node where the query is submitted.<br/>
 If the payment is sufficient, the network SHALL respond with the response
 type requested.<br/>
 If the response type is `COST_ANSWER` the payment MUST be unset.
 A state proof SHALL be available for some types of information.<br/>
 A state proof SHALL be available for a Record, but not a receipt, and the
 response entry for each supported "get info" query.
