Returns:

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

See Also:

getSchemaNormalizedValue

public java.lang.String getSchemaNormalizedValue()

[schema normalized value]

Specified by:

getSchemaNormalizedValue in interface org.apache.xerces.xs.ItemPSVI

Returns:

the normalized value of this item after validation

See Also:

getIsSchemaSpecified

public boolean getIsSchemaSpecified()

[schema specified]

Specified by:

getIsSchemaSpecified in interface org.apache.xerces.xs.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 org.apache.xerces.xs.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 org.apache.xerces.xs.ItemPSVI

Returns:

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

getErrorCodes

public org.apache.xerces.xs.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 org.apache.xerces.xs.ItemPSVI

Returns:

list of error codes

getValidationContext

public java.lang.String getValidationContext()

Description copied from interface: org.apache.xerces.xs.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 org.apache.xerces.xs.ItemPSVI

getTypeDefinition

public org.apache.xerces.xs.XSTypeDefinition getTypeDefinition()

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

Specified by:

getTypeDefinition in interface org.apache.xerces.xs.ItemPSVI

Returns:

a type declaration

getMemberTypeDefinition

public org.apache.xerces.xs.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 org.apache.xerces.xs.ItemPSVI

Returns:

a simple type declaration

getAttributeDeclaration

public org.apache.xerces.xs.XSAttributeDeclaration getAttributeDeclaration()

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

Specified by:

getAttributeDeclaration in interface org.apache.xerces.xs.AttributePSVI

Returns:

an attribute declaration

getActualNormalizedValue

public java.lang.Object getActualNormalizedValue()

Description copied from interface: org.apache.xerces.xs.ItemPSVI

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

Specified by:

getActualNormalizedValue in interface org.apache.xerces.xs.ItemPSVI

Following copied from interface: org.apache.xerces.xs.ItemPSVI

Throws:

org.apache.xerces.xs.XSException - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

getActualNormalizedValueType

public short getActualNormalizedValueType()

Description copied from interface: org.apache.xerces.xs.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 org.apache.xerces.xs.ItemPSVI

Following copied from interface: org.apache.xerces.xs.ItemPSVI

Throws:

org.apache.xerces.xs.XSException - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

getItemValueTypes

public org.apache.xerces.xs.ShortList getItemValueTypes()

Description copied from interface: org.apache.xerces.xs.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 org.apache.xerces.xs.ItemPSVI

Following copied from interface: org.apache.xerces.xs.ItemPSVI

Throws:

org.apache.xerces.xs.XSException - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.
