Class ChmPmgiHeader

java.lang.Object
  org.apache.tika.parser.chm.accessor.ChmPmgiHeader

All Implemented Interfaces:

Serializable, ChmAccessor<ChmPmgiHeader>

public class ChmPmgiHeader
extends Object
implements ChmAccessor<ChmPmgiHeader>

Description Note: not always exists An index chunk has the following format: 0000: char[4] 'PMGI' 0004: DWORD Length of quickref/free area at end of directory chunk 0008: Directory index entries (to quickref/free area) The quickref area in an PMGI is the same as in an PMGL The format of a directory index entry is as follows: BYTE: length of name BYTEs: name (UTF-8 encoded) ENCINT: directory listing chunk which starts with name Encoded Integers aka ENCINT An ENCINT is a variable-length integer. The high bit of each byte indicates "continued to the next byte". Bytes are stored most significant to least significant. So, for example, $EA $15 is (((0xEA&0x7F)<<7)|0x15) = 0x3515.
