      net.ontopia.infoset.impl.basic.GenericLocator

All Implemented Interfaces:

Externalizable, Serializable, LocatorIF

public class GenericLocator
extends AbstractLocator
implements Externalizable

INTERNAL: A generic locator class. Addresses of any notation can be used with this locator class. No normalization or absolutization is done.

Field Summary

protected String	address
protected String	notation

Constructor Summary

GenericLocator()
INTERNAL: No-argument constructor used by serialization.

GenericLocator(String notation, String address)

Method Summary

boolean	equals(Object object) PUBLIC: Two LocatorIFs are considered equal if they have the same address and notation properties.
String	getAddress() PUBLIC: Returns the locator address in absolute and normalized form.
String	getExternalForm() PUBLIC: Returns the address of the locator in external form; that is, with special characters that need to be escaped escaped using the escape syntax of the locator notation.
String	getNotation() PUBLIC: Gets the locator notation.
int	hashCode() PUBLIC: Returns the hashcode of the address property.
void	readExternal(ObjectInput in)
LocatorIF	resolveAbsolute(String address) PUBLIC: Given a locator address string that is relative to this locator, return an absolute locator.
void	writeExternal(ObjectOutput out)

GenericLocator

               throws IllegalArgumentException

Throws:

IllegalArgumentException

Method Detail

getNotation

public String getNotation()

Description copied from interface: LocatorIF

PUBLIC: Gets the locator notation. The default notation is URI. Ontopia will never use notation names which begin with 'x-'. Notation names are case-insensitive.

Note that only the URI notation is supported in release OKS 4.0 and newer.

Specified by:

getNotation in interface LocatorIF

getAddress

public String getAddress()

Description copied from interface: LocatorIF

PUBLIC: Returns the locator address in absolute and normalized form. Whether addresses are case-sensitive or not depends on the locator notation.

Specified by:

getAddress in interface LocatorIF

resolveAbsolute

public LocatorIF resolveAbsolute(String address)

Description copied from interface: LocatorIF

PUBLIC: Given a locator address string that is relative to this locator, return an absolute locator. If the input locator address is absolute the returned locator object will simply contain that absolute locator address.

Specified by:

resolveAbsolute in interface LocatorIF

getExternalForm

public String getExternalForm()

Description copied from interface: LocatorIF

PUBLIC: Returns the address of the locator in external form; that is, with special characters that need to be escaped escaped using the escape syntax of the locator notation.

Specified by:

getExternalForm in interface LocatorIF

hashCode

public int hashCode()

Description copied from class: AbstractLocator

PUBLIC: Returns the hashcode of the address property. All subclasses of AbstractLocator must use the same hashCode implementation in order to guarantee interoperability. E.g. when looking up LocatorIFs in Maps.

Overrides:

hashCode in class AbstractLocator

equals

public boolean equals(Object object)

Description copied from class: AbstractLocator

PUBLIC: Two LocatorIFs are considered equal if they have the same address and notation properties.

Overrides:

equals in class AbstractLocator

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException
