Method Summary

Modifier and Type	Method and Description
static int	getIndexFromPotentialInvalidPattern(String namespaceUri, NamespaceTable namespaceTable) Returns the NamespaceIndex of the given NamespaceUri using the given NamespaceTable with if not found, but recognizes special patterns returned by getUriOrUseInvalidPattern(int, NamespaceTable).
static int	getIndexFromPotentialInvalidPattern(UaNamespace namespace, NamespaceTable namespaceTable) Returns the NamespaceIndex of the given UaNamespace using the given NamespaceTable with if not found, but recognizes special patterns returned by getUriOrUseInvalidPattern(int, NamespaceTable).
static UaNamespace	getNamespace(String namespaceUri, NamespaceTable preLookupTable) Like UaNamespace.from(String), but first checks the given NamespaceTable for existing UaNamespace instances.
static UaNamespace	getNamespaceOrUseInvalidPattern(int namespaceIndex, NamespaceTable namespaceTable) Returns UaNamespace of the given NamespaceIndex based on the given NamespaceTable or creates a special pattern that getIndexFromPotentialInvalidPattern(String, NamespaceTable) can resolve back to the same int as the one given as parameter here.
static String	getUriOrUseInvalidPattern(int namespaceIndex, NamespaceTable namespaceTable) Returns NamespaceUri of the given NamespaceIndex based on the given NamespaceTable or creates a special pattern that getIndexFromPotentialInvalidPattern(String, NamespaceTable) can resolve back to the same int as the one given as parameter here.

Method Detail

getIndexFromPotentialInvalidPattern

public static int getIndexFromPotentialInvalidPattern(String namespaceUri,
                                                      NamespaceTable namespaceTable)
                                               throws ServiceResultException

Returns the NamespaceIndex of the given NamespaceUri using the given NamespaceTable with if not found, but recognizes special patterns returned by getUriOrUseInvalidPattern(int, NamespaceTable).

Throws:

ServiceResultException - if was not found and was not a special invalid uri pattern.

getIndexFromPotentialInvalidPattern

public static int getIndexFromPotentialInvalidPattern(UaNamespace namespace,
                                                      NamespaceTable namespaceTable)
                                               throws ServiceResultException

Returns the NamespaceIndex of the given UaNamespace using the given NamespaceTable with if not found, but recognizes special patterns returned by getUriOrUseInvalidPattern(int, NamespaceTable).

Throws:

ServiceResultException - if was not found and was not a special invalid uri pattern.

getNamespace

public static UaNamespace getNamespace(String namespaceUri,
                                       NamespaceTable preLookupTable)

Like UaNamespace.from(String), but first checks the given NamespaceTable for existing UaNamespace instances. The UaNamespace instances are interned, this method may perform better than just UaNamespace.from(String).

getNamespaceOrUseInvalidPattern

public static UaNamespace getNamespaceOrUseInvalidPattern(int namespaceIndex,
                                                          NamespaceTable namespaceTable)

Returns UaNamespace of the given NamespaceIndex based on the given NamespaceTable or creates a special pattern that getIndexFromPotentialInvalidPattern(String, NamespaceTable) can resolve back to the same int as the one given as parameter here.

getUriOrUseInvalidPattern

public static String getUriOrUseInvalidPattern(int namespaceIndex,
                                               NamespaceTable namespaceTable)

Returns NamespaceUri of the given NamespaceIndex based on the given NamespaceTable or creates a special pattern that getIndexFromPotentialInvalidPattern(String, NamespaceTable) can resolve back to the same int as the one given as parameter here.
