Method Detail

parse

public T parse(QName typeName,
               XNodeProcessorEvaluationMode mode)
        throws SchemaException

Specified by:

parse in interface ValueParser<T>

Throws:

SchemaException

canParseAs

public boolean canParseAs(QName typeName)

Description copied from interface: ValueParser

Checks if this parser can (by itself) parse the value as given type. (If it cannot, the parsing must be done by higher layers.) This method should be efficient. It may bring some performance penalty (when coupled with following parse() call) but we assume this situation is quite rare and performance effect is negligible.

Specified by:

canParseAs in interface ValueParser<T>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface ValueParser<T>

getStringValue

public String getStringValue()

Description copied from interface: ValueParser

Returns the value represented as string - in the best format that we can. This has to work even without knowing the exact data type. Therefore there is no guarantee that the returned value will be precise. This method is used as a "last instance" if everything else fails. Invocation of this method will not change the state of the xnode, e.g. it will NOT cause it to be parsed. It can be invoked without any side effects.

Specified by:

getStringValue in interface ValueParser<T>

toString

public String toString()

Overrides:

toString in class Object

getPotentiallyRelevantNamespaces

public Map<String,String> getPotentiallyRelevantNamespaces()

Description copied from interface: ValueParser

Returns namespaces that could be relevant when serializing unparsed string value of this item. Used to preserve xmlns declarations for QNames and ItemPaths in unparsed data. (MID-2196)

Specified by:

getPotentiallyRelevantNamespaces in interface ValueParser<T>

Returns:

May return null if not supported or no namespace declarations are present.

freeze

public ValueParser<T> freeze()

Specified by:

freeze in interface ValueParser<T>

Returns:

Frozen version of this parser.
