Class SnmpTableModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      com.ireasoning.protocol.snmp.SnmpTableModel

All Implemented Interfaces:

Serializable, TableModel

public class SnmpTableModel

extends AbstractTableModel

This class is the data representation of a MIB table. It also implements Swing's TableModel interface, so it can used directly by Swing's JTable class.

Constructor Detail

SnmpTableModel

public SnmpTableModel()

Constructor

SnmpTableModel

public SnmpTableModel(String tableName)

Constructor

Parameters:

tableName - table name

Method Detail

setTableName

public void setTableName(String tableName)

Sets table name

Parameters:

tableName - table name

getTableName

public String getTableName()

Returns the table name

getTableOID

public SnmpOID getTableOID()

Returns the table OID

setTableOID

public void setTableOID(SnmpOID oid)

Sets a new table OID

getRow

public SnmpVarBind[] getRow(int index)

Returns row at specified index

Throws:

IndexOutOfBoundsException - if index is out of range

getRowIndexSuffix

public String getRowIndexSuffix(int row)

Returns index suffix of a row. For example, for ifTable, getRowIndexSuffix(0) may return a string "1", which is the value of ifIndex of the row. It returns null if there's not enough data to determine index.

Parameters:

row - row index

getColumn

public SnmpVarBind[] getColumn(int index)

Returns the column at specified index

Throws:

IndexOutOfBoundsException - if index is out of range

addRow

public void addRow(SnmpVarBind[] vbs)

Adds a new row

Parameters:

vbs - an SnmpVarBind array of each column in this new row

getVarBindAt

public SnmpVarBind getVarBindAt(int row,
                                int column)

getValueAt

public Object getValueAt(int row,
                         int column)

Returns the value for the cell at columnIndex and rowIndex.

Throws:

IndexOutOfBoundsException - if row or column is out of range

setValueAt

public void setValueAt(Object aValue,
                       int rowIndex,
                       int columnIndex)

Sets the value in the cell at columnIndex and rowIndex to aValue.

Parameters:

aValue - the new value, must be an instance of a class implementing SnmpDataType interface

rowIndex - the row whose value is to be changed

columnIndex - the column whose value is to be changed

setTranslateValue

public void setTranslateValue(boolean b)

If passed b is true, subsequent calls to getValueAt(int row, int column) will use corresponding value defined in MIB. For example, "1" of ifAdminStatus will be translated to "up"
