Constructor Detail

SnmpNull

public SnmpNull()

Constructs a new SnmpNull.

SnmpNull

public SnmpNull(String dummy)

Constructs a new SnmpNull.
For mibgen private use only.

SnmpNull

public SnmpNull(int t)

Constructs a new SnmpNull from the specified tag value.

Parameters:

t - The initialization value.

Method Detail

getTag

public int getTag()

Returns the tag value of this SnmpNull.

Returns:

The value.

toString

public String toString()

Converts the NULL value to its ASN.1 String form. When the tag is not the universal one, it is prepended to the String form.

Overrides:

toString in class Object

Returns:

The String representation of the value.

toOid

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.

Specified by:

toOid in class SnmpValue

Returns:

The OID representation of the value.

duplicate

public final SnmpValue duplicate()

Performs a clone action. This provides a workaround for the SnmpValue interface.

Specified by:

duplicate in class SnmpValue

Returns:

The SnmpValue clone.

clone

public final Object clone()

Clones the SnmpNull object, making a copy of its data.

Overrides:

clone in class Object

Returns:

The object clone.

getTypeName

public final String getTypeName()

Returns a textual description of the type object.

Specified by:

getTypeName in class SnmpValue

Returns:

ASN.1 textual description.

isNoSuchObjectValue

public boolean isNoSuchObjectValue()

Checks if this SnmpNull object corresponds to a noSuchObject value.

Overrides:

isNoSuchObjectValue in class SnmpValue

Returns:

true if the tag equals SnmpDataTypeEnums.errNoSuchObjectTag, false otherwise.

isNoSuchInstanceValue

public boolean isNoSuchInstanceValue()

Checks if this SnmpNull object corresponds to a noSuchInstance value.

Overrides:

isNoSuchInstanceValue in class SnmpValue

Returns:

true if the tag equals SnmpDataTypeEnums.errNoSuchInstanceTag, false otherwise.

isEndOfMibViewValue

public boolean isEndOfMibViewValue()

Checks if this SnmpNull object corresponds to an endOfMibView value.

Overrides:

isEndOfMibViewValue in class SnmpValue

Returns:

true if the tag equals SnmpDataTypeEnums.errEndOfMibViewTag, false otherwise.
