public class Wildcard
A class that represents an XML Schema Wildcard. This is a helper class used to support the two distinct but similar schema components ElementWildcard and AttributeWildcard. A wilcard is represented by the XML elements xs:any and xs:anyAttribute

boolean |
isInexpressible()
Determine whether this wildcard represents an "inexpressible" intersection or union |
static boolean |
isNotStronger(String str1,
String str2)
Test whether one processContents value is <= the strength of another, where skip < lax < strict |
boolean |
isSubset(Wildcard sup,
NamePool pool)
Determine whether this wildcard is a subset of another wildcard. |
static Wildcard |
makeIntersection(Wildcard wat1,
Wildcard wat2,
NamePool pool)
Create an AttributeWildcard as the intersection of two AttributeWildcards. |
static Wildcard |
makeUnion(Wildcard wat1,
Wildcard wat2,
NamePool pool)
Create a AttributeWildcard as the union of two AttributeWildcards. |
boolean |
matches(int fingerprint,
boolean isElement,
Configuration config,
UserComplexType parentType)
Determine whether a name is allowed by this wildcard. |
boolean |
matches(String uri)
Determine whether a particular namespace is allowed by this wildcard. |
boolean |
overlaps(Wildcard other)
Determine whether this wildcard overlaps another wildcard, that is, whether there is an element that could match either. |
String |
reasonForNonMatch(int fingerprint,
boolean isElement,
Configuration config)
If matches() returns false, return a string explaining the reason for the non-match |
void |
serialize(SchemaModelSerializer serializer)
Serialize this schema component |
void |
setDisallowDefinedNames(boolean disallow)
Say that defined names are not allowed (notQName = "##defined") |
void |
setDisallowDefinedSiblings(boolean disallow)
Say that defined siblings are not allowed (notQName = "##definedSibling") |
void |
setNoNamespacesAllowed()
Initialize the set of permitted namespaces to an empty set. |
void |
setProcessContents(String process)
Sets the processContents attribute of the wildCard. |
String |
toString()
Get a string representation of this wildcard, used for diagnostics |
boolean |
validate(SchemaCompiler compiler)
Perform validation on this wildcard (this implementation of the method is a no-op) |

public void addAllowedNamespace(String namespace)
namespace
- the namespace to addpublic void addDisallowedNamespace(String namespace)
namespace
- the disallowed namespace to be addedpublic Set<String> getDisallowedNamespaces()
public boolean matches(String uri)
uri
- the namespace to be tested. Supply "" for the no-namespace.
public boolean matches(int fingerprint, boolean isElement, Configuration config, UserComplexType parentType)
fingerprint
- the fingerprint of the nameisElement
- true if looking for an element, false if looking for an attributeconfig
- the Saxon configurationparentType
- the governing type definition of the parent element, used to assess whether
the ##definedSibling constraint prevents an element from matching. May be null, in which case
##definedSibling is ignored.
public String reasonForNonMatch(int fingerprint, boolean isElement, Configuration config)
fingerprint
- the fingerprint of the nameisElement
- true if looking for an element, false if looking for an attributeconfig
- the Saxon configuration
public boolean disallowsQName(int fingerprint)
fingerprint
- the fingerprint of the name to be tested
public Set<String> getAllowedNamespaces()
public String getProcessContents()
public void setProcessContents(String process)
process
- the processContents value to set (e.g. "strict", "lax").
Validation of the value is the responsibility of the caller.public void setDisallowDefinedNames(boolean disallow)
disallow
- true if defined names are disallowedpublic boolean isDisallowDefinedNames()
public void setDisallowDefinedSiblings(boolean disallow)
disallow
- true if defined siblings are disallowedpublic boolean isDisallowDefinedSiblings()
public void addDisallowedQName(int fingerprint)
fingerprint
- the NamePool fingerprint of the disallowed namepublic boolean isDisallowedQName(int fingerprint)
fingerprint
- the NamePool fingerprint of the QName in question
public boolean validate(SchemaCompiler compiler) throws SchemaException
validate
in interface UserSchemaComponent
SchemaException
public String toString()
toString
in class Object
public boolean isSubset(Wildcard sup, NamePool pool)
sup
- the other wildcardpool
- the NamePool
public boolean overlaps(Wildcard other)
other
- the other wildcard
public static boolean isNotStronger(String str1, String str2)
str1
- the first processContents value, as a stringstr2
- the second processContents value, as a string
public int compareStrength(Wildcard other)
public static Wildcard makeIntersection(Wildcard wat1, Wildcard wat2, NamePool pool)
In XML Schema 1.1, the intersection of two wildcards is always expressible. The resulting wildcard might not be expressible using XML Schema 1.0, however.

serializer
- the object responsible for performing the serialization
