createRecord

public EscherRecord createRecord(byte[] data,
                                 int offset)

Specified by:: createRecord in interface EscherRecordFactory

Parameters:: data - The byte array containing the records; offset - The starting offset into the byte array
Returns:: The generated escher record

recordsToMap

protected static java.util.Map<java.lang.Short,java.lang.reflect.Constructor<? extends EscherRecord>> recordsToMap(java.lang.Class<?>[] recClasses)

Converts from a list of classes into a map that contains the record id as the key and the Constructor in the value part of the map. It does this by using reflection to look up the RECORD_ID field then using reflection again to find a reference to the constructor.

Parameters:: recClasses - The records to convert
Returns:: The map containing the id/constructor pairs.

isContainer

public static boolean isContainer(short options,
                                  short recordId)
