Module org.snmp4j.agent
Package org.snmp4j.agent.mo

Class DefaultMOTableRow

java.lang.Object
org.snmp4j.agent.mo.DefaultMOTableRow
All Implemented Interfaces:
Comparable<MOTableRow>, MOTableRow
Direct Known Subclasses:
DefaultMOMutableRow2PC
public class DefaultMOTableRow extends Object implements MOTableRow, Comparable<MOTableRow>
The DefaultMOTableRow is the default table row implementation. Instances are compared by their index value. The base row reference is not supported, since the default row implementation is designed for read-only tables. For mutable rows, use instances implementing the MOMutableTableRow interface.

      public static <V extends org.snmp4j.smi.Variable> V getColumnValue(MOTableRow row, MOTable<?,?,?> table, Class<MOColumn<V>> columnClass, SubRequest<?> subRequest)
      Gets the value of the first column (if it exists) in the specified row and table that matches (equals) the given column class. It starts searching for the column from the first column and then proceeds last until it finds it. If no matching column can be found, null is returned.
      Type Parameters:
      V - the value (Variable) class for this column.
      Parameters:
      row - a row with a RowStatus column (otherwise null is returned).
      table - the table of the given row.
      columnClass - the class of the column object.
      subRequest - an optional sub-request on which behalf this value retrieval is executed.
      Returns:
      the value of the matched column in the given row or null if the table has no column with the specified column class.
