Examples of com.foundationdb.server.rowdata.RowData

com.foundationdb.server.rowdata.RowData
Represent one or more rows of table data. The backing store is a byte array supplied in the constructor. The {@link #RowData(byte[],int,int)}constructor allows use of a partially filled reusable buffer. This class provides methods for both interpreting and constructing row data structures in the byte array. After a call to {@link #reset(int,int)} theindex will point to the first field of the first row represented in the buffer.
```
 +0: record length (Z)  +4: signature bytes, e.g., 'AB'  +6: field count (short)  +8: rowDefId (int)  +12: null-map (1 bit per schema-defined column) +M: fixed-length field  +N: fixed-length field ...  +Q: variable-length field +R: variable-length field ...  +Z-6: signature bytes: e.g., 'BA'  +Z-4: record length (Z)
