Interface Normalizer<T>

All Known Subinterfaces:

PolyStringNormalizer, StringNormalizer

@Experimental
public interface Normalizer<T>

Normalizes and matches (arbitrary) values, typically strings.

Method Summary

Modifier and Type	Method	Description
@NotNull QName	getName()	Returns the qualified name identifying this normalizer.
boolean	isIdentity()	`true` if the normalizer is known to be the default one, i.e., one that does no transformations.
boolean	match(T a, T b)	Matches two values.
boolean	matchRegex(T a, String regex)	Matches a value against regular expression (if supported).
T	normalize(T orig)	Returns a normalized version of the value.
default String	normalizeString(String orig)	Temporary solution for untyped relation between normalizers vs.

Method Details

normalize

@Contract("null -> null; !null -> !null")
T normalize(T orig)
     throws SchemaException

Returns a normalized version of the value.

Throws:

SchemaException

match

boolean match(@Nullable
 T a,
 @Nullable
 T b)
       throws SchemaException

Matches two values.

Throws:

SchemaException

matchRegex

boolean matchRegex(T a,
 String regex)
            throws SchemaException

Matches a value against regular expression (if supported).

Throws:

SchemaException

getName

@NotNull
@NotNull QName getName()

Returns the qualified name identifying this normalizer.

isIdentity

boolean isIdentity()

`true` if the normalizer is known to be the default one, i.e., one that does no transformations.

normalizeString

default String normalizeString(String orig)
                        throws SchemaException

Temporary solution for untyped relation between normalizers vs. matching rules. (See the wildcard return type of MatchingRule.getNormalizer(). We often need to normalize strings into PolyStrings.

Throws:

SchemaException
