fillFields
Description copied from class:EscherRecord
The contract of this method is to deserialize an escher record including it's children.- Overrides:
fillFields
in classEscherBlipRecord
- Parameters:
data
- The byte array containing the serialized escher records.offset
- The offset into the byte array.recordFactory
- A factory for creating new escher records.- Returns:
- The number of bytes written.
-
serialize
Description copied from class:EscherRecord
Serializes the record to an existing byte array.- Overrides:
serialize
in classEscherBlipRecord
- Parameters:
offset
- the offset within the byte arraydata
- the data array to serialize tolistener
- a listener for begin and end serialization events. This is useful because the serialization is hierarchical/recursive and sometimes you need to be able break into that.- Returns:
- the number of bytes written.
-
getRecordSize
