SnmpNull

• java.lang.Object
  • SnmpValue

Fields Summary
static final String	name Name of the type.
private int	tag This is the tag of the NULL value. By default, it is the universal tag value.

Constructors Summary
public SnmpNull() Constructs a new SnmpNull. tag = NullTag ;
public SnmpNull(String dummy) Constructs a new SnmpNull. For mibgen private use only. this();
public SnmpNull(int t) Constructs a new SnmpNull from the specified tag value. param t The initialization value. tag = t ;

Methods Summary
public final synchronized java.lang.Object	clone() Clones the SnmpNull object, making a copy of its data. return The object clone. SnmpNull newclone = null ; try { newclone = (SnmpNull) super.clone() ; newclone.tag = tag ; } catch (CloneNotSupportedException e) { throw new InternalError() ; // vm bug. } return newclone ;
public final synchronized SnmpValue	duplicate() Performs a clone action. This provides a workaround for the SnmpValue interface. return The SnmpValue clone. return (SnmpValue) clone() ;
public int	getTag() Returns the tag value of this SnmpNull. return The value. return tag ;
public final java.lang.String	getTypeName() Returns a textual description of the type object. return ASN.1 textual description. return name ;
public boolean	isEndOfMibViewValue() Checks if this SnmpNull object corresponds to an endOfMibView value. return true if the tag equals {@link com.sun.jmx.snmp.SnmpDataTypeEnums#errEndOfMibViewTag}, false otherwise. return (tag == SnmpDataTypeEnums.errEndOfMibViewTag);
public boolean	isNoSuchInstanceValue() Checks if this SnmpNull object corresponds to a noSuchInstance value. return true if the tag equals {@link com.sun.jmx.snmp.SnmpDataTypeEnums#errNoSuchInstanceTag}, false otherwise. return (tag == SnmpDataTypeEnums.errNoSuchInstanceTag);
public boolean	isNoSuchObjectValue() Checks if this SnmpNull object corresponds to a noSuchObject value. return true if the tag equals {@link com.sun.jmx.snmp.SnmpDataTypeEnums#errNoSuchObjectTag}, false otherwise. return (tag == SnmpDataTypeEnums.errNoSuchObjectTag);
public SnmpOid	toOid() Converts the NULL value to its SnmpOid form. Normally, a NULL value cannot be used as an index value, this method triggers an exception. return The OID representation of the value. throw new IllegalArgumentException() ;
public java.lang.String	toString() Converts the NULL value to its ASN.1 String form. When the tag is not the universal one, it is preprended to the String form. return The String representation of the value. String result = "" ; if (tag != 5) { result += "[" + tag + "] " ; } result += "NULL" ; switch(tag) { case errNoSuchObjectTag : result += " (noSuchObject)" ; break ; case errNoSuchInstanceTag : result += " (noSuchInstance)" ; break ; case errEndOfMibViewTag : result += " (endOfMibView)" ; break ; } return result ;
