Specified by:

constant in interface ItemPSVI

isConstant

public boolean isConstant()

Description copied from interface: ItemPSVI

Returns true if this specific instance of ItemPSVI is immutable, otherwise false.

Specified by:

isConstant in interface ItemPSVI

getSchemaDefault

public String getSchemaDefault()

[schema default]

Specified by:

getSchemaDefault in interface ItemPSVI

Returns:

The canonical lexical representation of the declaration's {value constraint} value.

See Also:

getSchemaNormalizedValue

public String getSchemaNormalizedValue()

[schema normalized value]

Specified by:

getSchemaNormalizedValue in interface ItemPSVI

Returns:

the normalized value of this item after validation

See Also:

getIsSchemaSpecified

public boolean getIsSchemaSpecified()

[schema specified]

Specified by:

getIsSchemaSpecified in interface ItemPSVI

Returns:

true - value was specified in schema, false - value comes from the infoset

See Also:

XML Schema Part 1: Structures [schema specified]

getValidationAttempted

public short getValidationAttempted()

Determines the extent to which the document has been validated

Specified by:

getValidationAttempted in interface ItemPSVI

Returns:

return the [validation attempted] property. The possible values are NO_VALIDATION, PARTIAL_VALIDATION and FULL_VALIDATION

getValidity

public short getValidity()

Determine the validity of the node with respect to the validation being attempted

Specified by:

getValidity in interface ItemPSVI

Returns:

return the [validity] property. Possible values are: UNKNOWN_VALIDITY, INVALID_VALIDITY, VALID_VALIDITY

getErrorCodes

public StringList getErrorCodes()

A list of error codes generated from validation attempts. Need to find all the possible subclause reports that need reporting

Specified by:

getErrorCodes in interface ItemPSVI

Returns:

list of error codes

getErrorMessages

public StringList getErrorMessages()

A list of error messages generated from the validation attempt or an empty StringList if no errors occurred during the validation attempt. The indices of error messages in this list are aligned with those in the [schema error code] list.

Specified by:

getErrorMessages in interface ItemPSVI

getValidationContext

public String getValidationContext()

Description copied from interface: ItemPSVI

The nearest ancestor element information item with a [schema information] property (or this element item itself if it has such a property). For more information refer to element validation context and attribute validation context .

Specified by:

getValidationContext in interface ItemPSVI

getTypeDefinition

public XSTypeDefinition getTypeDefinition()

An item isomorphic to the type definition used to validate this element.

Specified by:

getTypeDefinition in interface ItemPSVI

Returns:

a type declaration

getMemberTypeDefinition

public XSSimpleTypeDefinition getMemberTypeDefinition()

If and only if that type definition is a simple type definition with {variety} union, or a complex type definition whose {content type} is a simple thype definition with {variety} union, then an item isomorphic to that member of the union's {member type definitions} which actually validated the element item's normalized value.

Specified by:

getMemberTypeDefinition in interface ItemPSVI

Returns:

a simple type declaration

getAttributeDeclaration

public XSAttributeDeclaration getAttributeDeclaration()

An item isomorphic to the attribute declaration used to validate this attribute.

Specified by:

getAttributeDeclaration in interface AttributePSVI

Returns:

an attribute declaration

getActualNormalizedValue

public Object getActualNormalizedValue()

Description copied from interface: ItemPSVI

[schema normalized value]: Binding specific actual value or null if the value is in error.

Specified by:

getActualNormalizedValue in interface ItemPSVI

getActualNormalizedValueType

public short getActualNormalizedValueType()

Description copied from interface: ItemPSVI

The actual value built-in datatype, e.g. STRING_DT, SHORT_DT. If the type definition of this value is a list type definition, this method returns LIST_DT. If the type definition of this value is a list type definition whose item type is a union type definition, this method returns LISTOFUNION_DT. To query the actual value of the list or list of union type definitions use itemValueTypes. If the actualNormalizedValue is null, this method returns UNAVAILABLE_DT.

Specified by:

getActualNormalizedValueType in interface ItemPSVI

getItemValueTypes

public ShortList getItemValueTypes()

Description copied from interface: ItemPSVI

In the case the actual value represents a list, i.e. the actualNormalizedValueType is LIST_DT, the returned array consists of one type kind which represents the itemType . For example:

 <simpleType name="listtype"> <list 
 itemType="positiveInteger"/> </simpleType> <element 
 name="list" type="listtype"/> ... <list>1 2 3</list> 

The schemaNormalizedValue value is "1 2 3", the actualNormalizedValueType value is LIST_DT, and the itemValueTypes is an array of size 1 with the value POSITIVEINTEGER_DT.
If the actual value represents a list type definition whose item type is a union type definition, i.e. LISTOFUNION_DT, for each actual value in the list the array contains the corresponding memberType kind. For example:

 <simpleType 
 name='union_type' memberTypes="integer string"/> <simpleType 
 name='listOfUnion'> <list itemType='union_type'/> 
 </simpleType> <element name="list" type="listOfUnion"/> 
 ... <list>1 2 foo</list> 

The schemaNormalizedValue value is "1 2 foo", the actualNormalizedValueType is LISTOFUNION_DT , and the itemValueTypes is an array of size 3 with the following values: INTEGER_DT, INTEGER_DT, STRING_DT.

Specified by:

getItemValueTypes in interface ItemPSVI

getSchemaValue

public XSValue getSchemaValue()

Description copied from interface: ItemPSVI

If this item has a simple type definition or a complex type with simple content, then return the value with respect to the simple type. If this item doesn't have a simple-typed value, the behavior of this method is not specified.

Specified by:

getSchemaValue in interface ItemPSVI

reset

public void reset()

Reset()
