inlineinherited

Get number of matching fields.

Parameters

header

header

Returns

number of matching header fields

Definition at line 1460 of file JHead.hh.

    {
      const JHead head = getMatch(header);
 
      return head.size();
    }

match() [1/4]

bool JAANET::JHead::match ( const JHead & header ) const

inlineinherited

Test match of headers.

N.B.: If header 1 matches header 2, this does not necessarily imply header 2 matches header 1;
This is because header 1 may contain only a subsection of the fields of header 2 and vice versa.
E.g.: Header1:

       <tt>Header2</tt>:\n

            start_run: 1
            UUID: 09ee8c7a-4160-467e-99cf-0fee788e23d7
            primary: 16
            end_event:

In this case Header1.match(Header2) returns true, but not the other way around.

Parameters

header

second header

Returns

true if all header fields match; else false

Definition at line 1492 of file JHead.hh.

    {
      return getNumberOfMatches(header) == getNumberOfMatches(*this);
