Field Detail

NOT_AN_IDVALUE

protected IDValue NOT_AN_IDVALUE

Not a value (Unicode: #FFFF).

fIdentityConstraint

protected IdentityConstraint fIdentityConstraint

Identity constraint.

fValues

protected final org.apache.xerces.validators.common.XMLValidator.OrderedHashtable fValues

Current data values.

fValuesCount

protected int fValuesCount

Current data value count.

fValueTuples

protected final java.util.Vector fValueTuples

Data value tuples.

Constructor Detail

XMLValidator.ValueStoreBase

protected XMLValidator.ValueStoreBase(IdentityConstraint identityConstraint)

Constructs a value store for the specified identity constraint.

Method Detail

destroy

public void destroy()

append

public void append(XMLValidator.ValueStoreBase newVal)

startValueScope

public void startValueScope()
                     throws java.lang.Exception

Start scope for value store.

endValueScope

public void endValueScope()
                   throws java.lang.Exception

Ends scope for value store.

endDocumentFragment

public void endDocumentFragment()
                         throws java.lang.Exception

endDocument

public void endDocument()
                 throws java.lang.Exception

Signals the end of the document. This is where the specific instances of value stores can verify the integrity of the identity constraints.

reportNilError

public void reportNilError(IdentityConstraint id)
                    throws java.lang.Exception

Specified by:

reportNilError in interface ValueStore

addValue

public void addValue(Field field,
                     IDValue value)
              throws java.lang.Exception

Adds the specified value to the value store.

Specified by:

addValue in interface ValueStore

Parameters:

value - The value to add.

field - The field associated to the value. This reference is used to ensure that each field only adds a value once within a selection scope.

contains

public boolean contains(org.apache.xerces.validators.common.XMLValidator.OrderedHashtable tuple)

Returns true if this value store contains the specified values tuple.

duplicateValue

protected void duplicateValue(org.apache.xerces.validators.common.XMLValidator.OrderedHashtable tuple)
                       throws java.lang.Exception

Called when a duplicate value is added. Subclasses should override this method to perform error checking.

Parameters:

tuple - The duplicate value tuple.

toString

protected java.lang.String toString(org.apache.xerces.validators.common.XMLValidator.OrderedHashtable tuple)

Returns a string of the specified values.

toString

public java.lang.String toString()

Returns a string representation of this object.

Overrides:

toString in class java.lang.Object
