XQItemType

All Superinterfaces:

XQSequenceType
```
public interface XQItemType
extends XQSequenceType
```
The XQItemType interface represents an item type as defined in XQuery 1.0: An XML Query language.
The XQItemType extends the XQSequenceType but restricts the occurrance indicator to be exactly one. This derivation allows passing an item type wherever a sequence type is expected, but not the other way. The XQItemType interface contains methods to represent information about the following aspects of an item type:
- The kind of the item - one of XQITEMKIND_* constants
- The base type of the item - one of the XQBASETYPE_* constants. For atomic types this is the closest matching built-in XML Schema type, for element and attributes the closest matching built-in XML Schema type this node is based on.
- Name of the node, if any
- Type name, if any. If present, then also whether the typename is an anonymous type
- XML Schema URI associated with the type, if any
- The nillability characteristics, if any
An instance of the XQItemType is a standalone object that is independant of the XQConnection and any XQuery static or dynamic context.

- Method Detail
  - getBaseType
```
int getBaseType()
         throws XQException
```
    Returns the base type of the item. One of the XQBASETYPE_* constants.
    
    XQJ defines a constant for each of the built-in schema types defined in XML Schema. For atomic types this is the closest matching built-in XML Schema type, for element and attributes the closest matching built-in XML Schema type this node is based on.
    
    Returns:
    
    int one of the XQBASETYPE_* constants indicating the basic type of the item
    
    Throws:
    
    XQException - if the item kind is not one of: XQITEMKIND_DOCUMENT_ELEMENT, XQITEMKIND_DOCUMENT_SCHEMA_ELEMENT, XQITEMKIND_ELEMENT, XQITEMKIND_SCHEMA_ELEMENT, XQITEMKIND_ATTRIBUTE, XQITEMKIND_SCHEMA_ATTRIBUTE, or XQITEMKIND_ATOMIC
  - getItemKind
```
int getItemKind()
```
    Returns the kind of the item. One of the XQITEMKIND_* constants.
    
    Returns:
    
    int one of the XQITEMKIND_* constants indicating the basic kind of the item
  - getItemOccurrence
```
int getItemOccurrence()
```
    Returns the occurrence indicator for the item type. This method will always return the value XQSequenceType.OCC_EXACTLY_ONE.
    
    Specified by:
    
    getItemOccurrence in interface XQSequenceType
    
    Returns:
    
    int indicating the occurrence indicator
  - toString
```
String toString()
```
    Returns a human-readable implementation-defined string representation of the item type.
    
    Specified by:
    
    toString in interface XQSequenceType
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    String a string representation of the item type
  - getNodeName
```
QName getNodeName()
           throws XQException
```
    Returns the name of the node in case the item kind is an XQITEMKIND_DOCUMENT_ELEMENT, XQITEMKIND_DOCUMENT_SCHEMA_ELEMENT, XQITEMKIND_ELEMENT, XQITEMKIND_SCHEMA_ELEMENT, XQITEMKIND_ATTRIBUTE, or XQITEMKIND_SCHEMA_ATTRIBUTE. For example, in the case of a type for element "foo" this will return the QName foo. For wildcard entries a null value will be returned.
    
    Returns:
    
    QName for the name of the element, attribute, or document element node. null if it is a wildcard
    
    Throws:
    
    XQException - if the item kind is not one of: XQITEMKIND_DOCUMENT_ELEMENT, XQITEMKIND_DOCUMENT_SCHEMA_ELEMENT, XQITEMKIND_ELEMENT, XQITEMKIND_SCHEMA_ELEMENT, XQITEMKIND_ATTRIBUTE, or XQITEMKIND_SCHEMA_ATTRIBUTE
  - getSchemaURI
```
URI getSchemaURI()
```
    Returns the schema location URI of the schema that contains the item's element or type definition. This method is implementation-definied and an implementation will return a null value if it does not support retrieving the schema location URI. If the item corresponds to a validated global element in a schema, the result will be the schema location URI to the XMLSchema containing the element definition. Otherwise if the item is a schema validated node, the result will be the schema location URI of the XMLSchema containing the type definition of that node. If the item is not schema validated, the result is null
    
    Returns:
    
    URI representing the schema location URI of the XMLSchema containing the global element definition or the type definition of the current item. null in case the item is not schema validated or if the implementation does not support retrieving the schema URI.
  - getTypeName
```
QName getTypeName()
           throws XQException
```
    Represents a type name (global or local). This can be used to represent specific type name such as, element foo of type hatsize. The schema type name is represented as a single QName. If the return type is an anonymous type, the actual QName value returned is implementation defined.
    
    Returns:
    
    the QName of the schema type in case of a user defined or anonoymous types. For a built-in type, returns a predefined type name as QName (e.g.xs:anyType, xs:decimal, etc). Cannot be null
    
    Throws:
    
    XQException - if the item kind is not one of: XQITEMKIND_DOCUMENT_ELEMENT, XQITEMKIND_DOCUMENT_SCHEMA_ELEMENT, XQITEMKIND_ATOMIC, XQITEMKIND_ELEMENT, XQITEMKIND_SCHEMA_ELEMENT, XQITEMKIND_ATTRIBUTE, or XQITEMKIND_SCHEMA_ATTRIBUTE
  - isAnonymousType
```
boolean isAnonymousType()

```
String getPIName()
          throws XQException
```
    Returns the name of the processing instruction type. As such the item kind of this XQItemType must be XQITEMKIND_PI.
    
    Returns:
    
    the name of the processing instruction type. null if it is a wildcard
    
    Throws:
    
    XQException - if the item kind is not XQITEMKIND_PI
  - equals
```
boolean equals(Object o)
```
    Compares the specified object with this item type for equality. The result is true only if the argument is an item type object which represents the same XQuery item type.
    
    In order to comply with the general contract of equals and hashCode across different implementations the following algorithm must be used. Return true if and only if both objects are XQItemType and:
    - getItemKind() is equal
    - if getBaseType() is supported for the item kind, it must be equal
    - if getNodeName() is supported for the item kind, it must be equal
    - getSchemaURI() is equal
    - if getTypeName() is supported for the item kind, it must be equal
    - isAnonymousType() is equal
    - isElementNillable() is equal
    - if getPIName() is supported for the item kind, it must be equal
    Specified by:
    
    equals in interface XQSequenceType
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - an XQItemType object representing an XQuery item type
    
    Returns:
    
    true if the input item type object represents the same XQuery item type, false otherwise
  - hashCode
```
int hashCode()
```
    Returns a hash code consistent with the definition of the equals method.
    
    In order to comply with the general contract of equals and hashCode across different implementations the following algorithm must be used:
```
  hashCode = this.getItemKind();
  if this.getSchemaURI != null
    hashCode = 31*hashCode + this.getSchemaURI().hashCode();
  if this.getBaseType() is supported for the item kind
    hashCode = 31*hashCode + this.getbaseType();
  if this.getNodeName () is supported for the item kind and
    this.getNodeName() != null
    hashCode = 31*hashCode + this.getNodeName().hashCode()
  if this.getTypeName () is supported for the item kind
    hashCode = 31*hashCode + this.getTypeName().hashCode();
  if this.getPIName () is supported for the item kind and
    this.getPIName () != null
    hashCode = 31*hashCode + this.getPIName().hashCode();
 
```
    Specified by:
    
    hashCode in interface XQSequenceType
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    hash code for this item type
