NameMapImpl (Jackcess 5.0.2 API)

java.lang.Object
- com.healthmarketscience.jackcess.impl.NameMapImpl

All Implemented Interfaces:

NameMap, Iterable<NameMap.Record>

Direct Known Subclasses:

QueryNameMapImpl, TableNameMapImpl
```
public abstract class NameMapImpl
extends Object
implements NameMap
```
Reads and writes a name map, which tables and queries share. The encoding is
```
   NameMap := magic [u32 reserved record*]
   record  := guid own, u32 type, byte[16] payload, utf16 name, u32 zero
```
The name is null terminated. The trailing zero is left off the last record, and there is no record count, so a reader stops at the end of the data. The payload is a date and 8 bytes of writer state for a table record, the table guid for a column or a reference record, and the writer tag for the end record. A query which tracks no names, such as a union or a pass-through query, has the magic alone.
