Class Variable

parseRaw

• parseRaw(raw: Buffer, fmt: string): void

• Parse Member information from XPORT file. Here is the C structure definition for the namestr record:

  struct NAMESTR {
  short ntype; / VARIABLE TYPE: 1=NUMERIC, 2=CHAR /
  short nhfun; / HASH OF NNAME (always 0) /
  short nlng; / LENGTH OF VARIABLE IN OBSERVATION /
  short nvar0; / VARNUM /
  char8 nname; / NAME OF VARIABLE /
  char40 nlabel; / LABEL OF VARIABLE /
  char8 nform; / NAME OF FORMAT /
  short nfl; / FORMAT FIELD LENGTH OR 0 /
  short nfd; / FORMAT NUMBER OF DECIMALS /
  short nfj; / 0=LEFT JUSTIFICATION, 1=RIGHT JUST /
  char nfill[2]; / (UNUSED, FOR ALIGNMENT AND FUTURE) /
  char8 niform; / NAME OF INPUT FORMAT /
  short nifl; / INFORMAT LENGTH ATTRIBUTE /
  short nifd; / INFORMAT NUMBER OF DECIMALS /
  long npos; / POSITION OF VALUE IN OBSERVATION /
  char rest[52]; / remaining fields are irrelevant /
  };

  Note that the length given in the last 4 bytes of the member header record indicates the actual number of bytes for the NAMESTR structure. The size of the structure listed above is 140 bytes. Under VAX/VMS, the size will be 136 bytes, meaning that the 'rest' variable may be truncated.

  Parameters

  • raw: Buffer

    Raw description of a varilable.

  • fmt: string

    Struct format used to parse the binary data.

  Returns void
