Interface ItemPSVI

All Known Subinterfaces:
  AttributePSVI, ElementPSVI

public interface ItemPSVI

Represents an abstract PSVI item for an element or an attribute information item.

Field Summary
`static short` | `VALIDATION_FULL` Validation status indicating that full schema validation has been performed on the item.
`static short` | `VALIDATION_NONE` Validation status indicating that schema validation has been performed and the item in question has specifically been skipped.
`static short` | `VALIDATION_PARTIAL` Validation status indicating that schema validation has been performed on the item in question under the rules of lax validation.
`static short` | `VALIDITY_INVALID` Validity value indicating that validation has been strictly assessed and the item in question is invalid according to the rules of schema validation.
`static short` | `VALIDITY_NOTKNOWN` Validity value indicating that validation has either not been performed or that a strict assessment of validity could not be performed.
`static short` | `VALIDITY_VALID` Validation status indicating that schema validation has been performed and the item in question is valid according to the rules of schema validation.

Method Summary
`java.lang.Object` | `getActualNormalizedValue()` `[schema normalized value]`: Binding specific actual value or `null` if the value is in error.
`short` | `getActualNormalizedValueType()` The actual value built-in datatype, e.g.
`StringList` | `getErrorCodes()` `[schema error code]`: a list of error codes generated from the validation attempt or an empty `StringList` if no errors occurred during the validation attempt.
`boolean` | `getIsSchemaSpecified()` `[schema specified]`: if true, the value was specified in the schema.
`ShortList` | `getItemValueTypes()` In the case the actual value represents a list, i.e.
`XSSimpleTypeDefinition` | `getMemberTypeDefinition()` `[member type definition]`: 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 type definition with {variety} union, then an item isomorphic to that member of the union's {member type definitions} which actually validated the schema item's normalized value.
`java.lang.String` | `getSchemaDefault()` `[schema default]`: the canonical lexical representation of the declaration's {value constraint} value.
`java.lang.String` | `getSchemaNormalizedValue()` `[schema normalized value]`: the normalized value of this item after validation.
`XSTypeDefinition` | `getTypeDefinition()` `[type definition]`: an item isomorphic to the type definition used to validate the schema item.
`short` | `getValidationAttempted()` `[validation attempted]`: determines the extent to which the schema item has been validated.
`java.lang.String` | `getValidationContext()` The nearest ancestor element information item with a `[schema information]` property (or this element item itself if it has such a property).
`short` | `getValidity()` `[validity]`: determines the validity of the schema item with respect to the validation being attempted.

Field Detail

### VALIDITY_NOTKNOWN

    public static final short VALIDITY_NOTKNOWN

  Validity value indicating that validation has either not been performed or that a strict assessment of validity could not be performed.

### VALIDITY_INVALID

    public static final short VALIDITY_INVALID

  Validity value indicating that validation has been strictly assessed and the item in question is invalid according to the rules of schema validation.

### VALIDITY_VALID

    public static final short VALIDITY_VALID

  Validation status indicating that schema validation has been performed and the item in question is valid according to the rules of schema validation.

### VALIDATION_NONE

    public static final short VALIDATION_NONE

  Validation status indicating that schema validation has been performed and the item in question has specifically been skipped.

### VALIDATION_PARTIAL

    public static final short VALIDATION_PARTIAL

  Validation status indicating that schema validation has been performed on the item in question under the rules of lax validation.

### VALIDATION_FULL

    public static final short VALIDATION_FULL

  Validation status indicating that full schema validation has been performed on the item.

Method Detail

### getValidationContext

    public java.lang.String getValidationContext()

  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 .

### getValidity

    public short getValidity()

  `[validity]`: determines the validity of the schema item with respect to the validation being attempted. The value will be one of the constants: `VALIDITY_NOTKNOWN`, `VALIDITY_INVALID` or `VALIDITY_VALID`.

### getValidationAttempted

    public short getValidationAttempted()

  `[validation attempted]`: determines the extent to which the schema item has been validated. The value will be one of the constants: `VALIDATION_NONE`, `VALIDATION_PARTIAL` or `VALIDATION_FULL`.

### getErrorCodes

    public StringList getErrorCodes()

  `[schema error code]`: a list of error codes generated from the validation attempt or an empty `StringList` if no errors occurred during the validation attempt.

### getSchemaNormalizedValue

    public java.lang.String getSchemaNormalizedValue()

  `[schema normalized value]`: the normalized value of this item after validation.

### getActualNormalizedValue

    public java.lang.Object getActualNormalizedValue()
                                              throws XSException

  `[schema normalized value]`: Binding specific actual value or `null` if the value is in error.
  Throws:
    `XSException` - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

### getActualNormalizedValueType

    public short getActualNormalizedValueType()
                                       throws XSException

  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` .
  Throws:
    `XSException` - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

### getItemValueTypes

    public ShortList getItemValueTypes()
                                throws XSException

  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`.
  Throws:
    `XSException` - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

### getTypeDefinition

    public XSTypeDefinition getTypeDefinition()

  `[type definition]`: an item isomorphic to the type definition used to validate the schema item.

### getMemberTypeDefinition

    public XSSimpleTypeDefinition getMemberTypeDefinition()

  `[member type definition]`: 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 type definition with {variety} union, then an item isomorphic to that member of the union's {member type definitions} which actually validated the schema item's normalized value.

### getSchemaDefault

    public java.lang.String getSchemaDefault()

  `[schema default]`: the canonical lexical representation of the declaration's {value constraint} value. For more information refer to element schema default and attribute schema default.

### getIsSchemaSpecified

    public boolean getIsSchemaSpecified()

  `[schema specified]`: if true, the value was specified in the schema. If false, the value comes from the infoset. For more information refer to element specified and attribute specified.
