Constructor Detail

Facet

public Facet()

Method Detail

isFixed

public boolean isFixed()

Test if the facet is defined in the schema with fixed="true"

Returns:

true if fixed

setFixed

public void setFixed(boolean fixed)

Set whether the facet is defined as fixed

Parameters:

fixed - true if the facet is fixed

getName

public String getName()

Returns the name of this Facet

Returns:

the name of this Facet

getValue

public String getValue()

Returns the character (String) representation of this facet

Returns:

the value of this facet

toLong

public long toLong()
            throws NumberFormatException

Returns the numeric value of this facet

Returns:

a long representation of the value of this facet

Throws:

NumberFormatException

checkFacetRestriction

public void checkFacetRestriction(UserSimpleType type,
                                  SimpleType base)
                           throws SchemaException,
                                  ValidationException

Check that this facet is legal when used on a type derived by restriction

Parameters:

type - the type on which the facet is defined

base - the type from which the restricted type is derived

Throws:

SchemaException - if the facet is not legal

ValidationException

isNewlyIntroduced

public boolean isNewlyIntroduced(SimpleType base)

Test whether this facet is newly introduced on this type, that is, whether it is absent from the base type

appliesToWholeList

public boolean appliesToWholeList()

Test whether this is a facet that can be used to test the normalized value of a list type. (Specifically, this is true only for pattern facets and enumeration facets)

testAtomicValue

public boolean testAtomicValue(AtomicValue value)

Test whether an atomic value conforms to this facet

Parameters:

value - the value to be tested

Returns:

true if the value conforms; false if it doesn't conform, or if the test fails

testLength

public boolean testLength(int count)

Test whether the length of a list conforms to this facet. Always true except for length facets

getWhitespaceAction

public int getWhitespaceAction()

Get the whitespace action required by this facet: one of PRESERVE, REPLACE, or COLLAPSE. Returns a dummy value of PRESERVE for facets other than whitespace facets.

serialize

public void serialize(SchemaSerializer serializer)
               throws IOException

Serialize the schema component

Specified by:

serialize in interface SerializableSchemaComponent

Throws:

IOException

getComponentTypeCode

public int getComponentTypeCode()

Get a unique number identifying the type of component

Specified by:

getComponentTypeCode in interface SerializableSchemaComponent
