Examples with SnmpPduBulkType com.sun.jmx.snmp.SnmpPduBulkType used on opensource projects

Example 1 with SnmpPduBulkType

use of com.sun.jmx.snmp.SnmpPduBulkType in project jdk8u_jdk by JetBrains.

the class SnmpV3Message method encodeSnmpPdu.

/**
     * Initializes this message with the specified <CODE>pdu</CODE>.
     * <P>
     * This method initializes the data field with an array of
     * <CODE>maxDataLength</CODE> bytes. It encodes the <CODE>pdu</CODE>.
     * The resulting encoding is stored in the data field
     * and the length of the encoding is stored in <CODE>dataLength</CODE>.
     * <p>
     * If the encoding length exceeds <CODE>maxDataLength</CODE>,
     * the method throws an exception.
     *
     * @param p The PDU to be encoded.
     * @param maxDataLength The maximum length permitted for the data field.
     *
     * @exception SnmpStatusException If the specified <CODE>pdu</CODE>
     *   is not valid.
     * @exception SnmpTooBigException If the resulting encoding does not fit
     * into <CODE>maxDataLength</CODE> bytes.
     * @exception ArrayIndexOutOfBoundsException If the encoding exceeds
     *    <CODE>maxDataLength</CODE>.
