Method Detail

checkSyntax

public void checkSyntax(java.lang.String value)
                 throws PObjSyntaxException

Specified by:

checkSyntax in interface Type

Overrides:

checkSyntax in class StringType

Throws:

PObjSyntaxException

getIPv4Address

public final java.lang.String getIPv4Address(java.lang.String network)

Returns the IPv4 address of the network.

For the network 192.168.25.0/24 the returned IPv4 address is 192.168.25.0.

Throws:

java.lang.IllegalArgumentException - if the string is null, empty or does not represent a valid network.

getNetmask

public final java.lang.String getNetmask(java.lang.String network)

Returns the IPv4 network mask.

For the network 192.168.25.0/24 the returned network mask is 255.255.255.0.

Throws:

java.lang.IllegalArgumentException - if the string is null, empty or does not represent a valid network.
