NullType

public NullType()

Creates a new null MIB type.

Method Detail

initialize

public MibType initialize(MibSymbol symbol,
                 MibLoaderLog log)

Initializes the MIB type. This will remove all levels of indirection present, such as references to types or values. No information is lost by this operation. This method may modify this object as a side-effect, and will return the basic type.

NOTE: This is an internal method that should only be called by the MIB loader.

Specified by:

initialize in class MibType

Parameters:

symbol - the MIB symbol containing this type

log - the MIB loader log

Returns:

the basic MIB type

Since:

2.2

createReference

public MibType createReference()

Creates a type reference to this type. The type reference is normally an identical type, but with the primitive flag set to false. Only certain types support being referenced, and the default implementation of this method throws an exception.

NOTE: This is an internal method that should only be called by the MIB loader.

Overrides:

createReference in class MibType

Returns:

the MIB type reference

Since:

2.2

isCompatible

public boolean isCompatible(MibValue value)

Checks if the specified value is compatible with this type. A value is compatible if and only if it is a null value.

Specified by:

isCompatible in class MibType

Parameters:

value - the value to check

Returns:

true if the value is compatible, or false otherwise
