Constructor Detail

Ip4AddressRegister

public Ip4AddressRegister()

Creates a new null-valued register.

Method Detail

setNull

public void setNull()

Description copied from interface: TokenSettable

Sets the contained value to be null valued.

Specified by:

setNull in interface TokenSettable

setZero

public void setZero()

Description copied from interface: TokenSettable

Sets the contained value to be zero valued.

Specified by:

setZero in interface TokenSettable

set

public void set(byte[] value)

Description copied from interface: Ip4AddressSettable

Sets the container to the given raw ip value.

Specified by:

set in interface Ip4AddressSettable

Parameters:

value - raw address value to which to set the container

set

public void set(Inet4Address value)

Description copied from interface: Ip4AddressSettable

Sets the container to the given Inet4Address value.

Specified by:

set in interface Ip4AddressSettable

Parameters:

value - Inet4Address value to which to set the container

set

public void set(TokenValued value)

Description copied from interface: TokenSettable

Sets the contained value to the given token value. The given value must have a type compatible with this object.

Specified by:

set in interface TokenSettable

Parameters:

value - the value to which to set the container

getType

public final ScalarTokenType getType()

Description copied from interface: TokenValued

Gets the data type of the token. This type will dictate the valid values that can be contained.

Specified by:

getType in interface ScalarValued

Specified by:

getType in interface TokenValued

Specified by:

getType in interface ScalarTyped

Specified by:

getType in interface TokenTyped

Returns:

the token type.

asAddress

public final byte[] asAddress()

Description copied from interface: Ip4AddressValued

Gets the contained raw IPv4 address value. The array returned is a copy of the binary data contained in the object.

Specified by:

asAddress in interface Ip4AddressValued

Returns:

the contained value as a byte[4]. If null valued, as indicated by TokenValued.isNull(), null is returned.

asInet4Address

public final Inet4Address asInet4Address()

Description copied from interface: Ip4AddressValued

Gets the contained IP address as an Inet4Address.

Specified by:

asInet4Address in interface Ip4AddressValued

Returns:

the contained value as a Inet4Address. If null valued, as indicated by TokenValued.isNull(), null is returned.

isZero

public final boolean isZero()

Description copied from interface: ScalarValued

Indicates whether the value is the zero value for the type. Zero values are not stored in sparse representation formats.

Specified by:

isZero in interface ScalarValued

Returns:

true if the value is the zero value, false otherwise.

toString

public String toString()

Overrides:

toString in class Object

isNull

public final boolean isNull()

Description copied from interface: TokenValued

Indicates whether the token is null valued. Tokens support null values analogous to SQL. Before accessing the value of the container, it is usually best to ensure it is not null valued using this method.

Specified by:

isNull in interface TokenValued

Returns:

true if the token is null valued, false otherwise
