Method Detail

compileForIpVersion

protected IRawInetAddressAuthorizer compileForIpVersion(java.lang.String filter)
                                                 throws java.net.UnknownHostException

Compiles for IPv4 specific address filter strings.

Specified by:

compileForIpVersion in class AbstractInetAddressAuthorizerCompiler

Parameters:

filter -

Returns:

Throws:

java.net.UnknownHostException

getAddressSeparator

protected java.lang.String getAddressSeparator()

Specified by:

getAddressSeparator in class AbstractInetAddressAuthorizerCompiler

Returns:

getBroadcastString

protected java.lang.String getBroadcastString()

Specified by:

getBroadcastString in class AbstractInetAddressAuthorizerCompiler

Returns:

getOctetFromString

protected short getOctetFromString(java.lang.String octect)

Mechanism to pull a short from the provided textual octet. Use short values as we have to do comparisons and bytes are signed (and we'd have to add 254 prior to comparison, blah, blah, blah)

Parameters:

octect -

Returns:

convertAddressBytesToShort

public static short[] convertAddressBytesToShort(byte[] bytes)

Utility method to convert between the actual byte[] address representation and a short[] used to perform the address and range comparison.

Parameters:

bytes -

Returns:

convertShortToAddressBytes

public static byte[] convertShortToAddressBytes(short[] shorts)

Utility method to convert between the short[] used for comparison and a byte[] for actual address representation.

Parameters:

shorts -

Returns:
