Method Detail

match

default boolean match(Object inputVal,
                      Operand op,
                      Object val,
                      String name,
                      Row row)

convertVal

default Object convertVal(Object val)

projectAddReplica

default void projectAddReplica(Cell cell,
                               ReplicaInfo ri,
                               Consumer<org.apache.solr.client.solrj.cloud.autoscaling.Row.OperationInfo> opCollector,
                               boolean strictMode)

addViolatingReplicas

default boolean addViolatingReplicas(org.apache.solr.client.solrj.cloud.autoscaling.Violation.Ctx ctx)

getSuggestions

void getSuggestions(org.apache.solr.client.solrj.cloud.autoscaling.Suggestion.Ctx ctx)

computeValue

default Object computeValue(Policy.Session session,
                            Condition condition,

                                  Consumer<org.apache.solr.client.solrj.cloud.autoscaling.Row.OperationInfo> opCollector)

postValidate

default String postValidate(Condition condition)

getOperand

default Operand getOperand(Operand expected,
                           Object strVal,
                           ComputedType computedType)

validate

Object validate(String name,
                Object val,
                boolean isRuleVal)
