Constructor Detail

AttributeWildcard

public AttributeWildcard()

isInexpressible

public boolean isInexpressible()

Determine whether this wildcard represents an "inexpressible" intersection or union

Returns:

true if the intersection or union is inexpressible, as defined in XML Schema. This is essentially an error condition, so the wildcard should not be used if this property is true.

getStructureType

public short getStructureType()

Returns the type of this SchemaElement

Specified by:

getStructureType in class SchemaElement

Returns:

the type of this SchemaElement: always SchemaElement.WILDCARD_ATTRIBUTE

makeIntersection

public static AttributeWildcard makeIntersection(AttributeWildcard wat1,
                                                 AttributeWildcard wat2)

Create an AttributeWildcard as the intersection of two AttributeWildcards. For internal use only.

Parameters:

wat1 - the first operand: the processContents is taken from this operand

wat2 - the second operand

Returns:

a new AttributeWildcard representing the intersection, as defined in Schema Component Constraint: Attribute Wildcard Intersection; if the intersection "is not expressible" this will be flagged as such, for later rejection by the validator.

makeUnion

public static AttributeWildcard makeUnion(AttributeWildcard wat1,
                                          AttributeWildcard wat2)

Create a AttributeWildcard as the union of two AttributeWildcards. For internal use only.

Parameters:

wat1 - the first operand: the processContents is taken from this operand

wat2 - the second operand

Returns:

a new AttributeWildcard representing the intersection, as defined in Schema Component Constraint: Attribute Wildcard Union; if the union "is not expressible" then the result will be marked as such, for later use by the validator.

validate

public boolean validate(Schema schema)
                 throws javax.xml.transform.TransformerException

Validate that this AttributeWildcard obeys the schema consistency rules. Any errors are notified to the ErrorListener, and result in the method returning false.

Overrides:

validate in class Wildcard

Parameters:

schema - the containing schema (used for error reporting)

Returns:

false if any errors were found, true if everything is OK

Throws:

javax.xml.transform.TransformerException - if the error listener decided to treat the error as fatal.
