## org.apache.xerces.xs
Interface XSAttributeDeclaration

All Superinterfaces:
  XSObject

public interface XSAttributeDeclaration
extends XSObject

The interface represents the Attribute Declaration schema component.

Method Summary
`java.lang.Object` | `getActualVC()` Value Constraint: Binding specific actual constraint value or `null` if the value is in error or there is no value constraint.
`short` | `getActualVCType()` The actual constraint value built-in datatype, e.g.
`XSAnnotation` | `getAnnotation()` An annotation if it exists, otherwise `null`.
`short` | `getConstraintType()` Value constraint: one of `VC_NONE, VC_DEFAULT, VC_FIXED`.
`java.lang.String` | `getConstraintValue()` Value constraint: The constraint value with respect to the [type definition], otherwise `null`.
`XSComplexTypeDefinition` | `getEnclosingCTDefinition()` The complex type definition for locally scoped declarations (see `scope`), otherwise `null` if no such definition exists.
`ShortList` | `getItemValueTypes()` In the case the actual constraint value represents a list, i.e.
`short` | `getScope()` [scope].
`XSSimpleTypeDefinition` | `getTypeDefinition()` [type definition]: A simple type definition.

Method Detail

### getTypeDefinition

    public XSSimpleTypeDefinition getTypeDefinition()

  [type definition]: A simple type definition.

### getScope

    public short getScope()

  [scope]. One of `SCOPE_GLOBAL`, `SCOPE_LOCAL`, or `SCOPE_ABSENT`. If the scope is local, then the `enclosingCTDefinition` is present.

### getEnclosingCTDefinition

    public XSComplexTypeDefinition getEnclosingCTDefinition()

  The complex type definition for locally scoped declarations (see `scope`), otherwise `null` if no such definition exists.

### getConstraintType

    public short getConstraintType()

  Value constraint: one of `VC_NONE, VC_DEFAULT, VC_FIXED`.

### getConstraintValue

    public java.lang.String getConstraintValue()

  Value constraint: The constraint value with respect to the [type definition], otherwise `null`.

### getActualVC

    public java.lang.Object getActualVC()
                                 throws XSException

  Value Constraint: Binding specific actual constraint value or `null` if the value is in error or there is no value constraint.
  Throws:
    `XSException` - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

### getActualVCType

    public short getActualVCType()
                          throws XSException

  The actual constraint 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 constraint value of the list or list of union type definitions use `itemValueTypes`. If the `actualValue` 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 constraint value represents a list, i.e. the `actualValueType` is `LIST_DT`, the returned array consists of one type kind which represents the itemType. If the actual constraint value represents a list type definition whose item type is a union type definition, i.e. `LISTOFUNION_DT`, for each actual constraint value in the list the array contains the corresponding memberType kind. For examples, see `ItemPSVI.itemValueTypes`.
  Throws:
    `XSException` - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.

### getAnnotation

    public XSAnnotation getAnnotation()

  An annotation if it exists, otherwise `null`.
