Method Detail

values

public static HttpdAddressUtility[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (HttpdAddressUtility c : HttpdAddressUtility.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static HttpdAddressUtility valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

get

public static HttpdAddressUtility get(String version)

getAllMainServerAddresses

public abstract List<HttpdAddressUtility.Address> getAllMainServerAddresses(ApacheDirectiveTree ag,
                                                                            boolean substituteWildcards)

This returns all the addresses the server listens on.

Parameters:

ag - the tree of the httpd configuration

substituteWildcards - true if wildcard substitution should be made on host and port specs

Returns:

the addresses or null on failure

getMainServerSampleAddress

public HttpdAddressUtility.Address getMainServerSampleAddress(ApacheDirectiveTree ag,
                                                              String limitToHost,
                                                              int limitToPort)

This just constructs a first available address under which the server or one of its virtual hosts can be reached.

Parameters:

ag - the tree of the httpd configuration

limitToHost - if non-null and different from HttpdAddressUtility.Address.DEFAULT_HOST and HttpdAddressUtility.Address.WILDCARD, the sample address is looked for only for the given host

limitToPort - if > 0, the sample address is looked for only for the given port

Returns:

the address or null on failure

getVirtualHostSampleAddress

public HttpdAddressUtility.Address getVirtualHostSampleAddress(ApacheDirectiveTree ag,
                                                               String virtualHost,
                                                               String serverName)

This constructs an address on which given virtual host can be accessed.

Parameters:

ag - the augeas tree of the httpd configuration

virtualHost - the port or address:port of the virtual host

serverName - the server name for the namebased virtual hosts (or null if the virtual host is ip based)

Returns:

the address on which the virtual host can be accessed or null on error

getHttpdInternalMainServerAddressRepresentation

public HttpdAddressUtility.Address getHttpdInternalMainServerAddressRepresentation(ApacheDirectiveTree runtimeConfig)

getHttpdInternalVirtualHostAddressRepresentation

public HttpdAddressUtility.Address getHttpdInternalVirtualHostAddressRepresentation(ApacheDirectiveTree runtimeConfig,
                                                                                    String virtualHost,
                                                                                    String serverName)
