Class SearchSortSpecification


java.lang.Object

  +--oracle.ifs.search.SearchSortSpecification

All Implemented Interfaces:
java.lang.Cloneable, java.io.Serializable

public final class SearchSortSpecification
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable

A SearchSortSpecification represents the order-by-clause of the Select statement. Attribute names can be qualified by the SearchClass. Also provides a way to specify ASCENDING or DESCEDING order based on the attribute.

 // Code Sample
 //
 // Following code shows a SearchSortSpecification which represents
 // ORDER by DOCUMENT.NAME, FOLDER.NAME 
 //
 // Array of classes involved in the order by clause
 String [] sortClasses = new String[] {"DOCUMENT", "FOLDER"}
 //
 // Array of Attribute Names to match class names.
 String [] attNames = new String[] {"NAME", "NAME"}
 //
 // Order of Sort for each sort element
 boolean [] orders = new boolean[] {true, false}
 //
 // Create the SortSpecification
 SearchSortSpecification someSortSpec = new SearchSortSpecification(sortClasses, attNames, orders);

Constructor Detail

SearchSortSpecification


public SearchSortSpecification(java.lang.String defaultClass)
Constructs a SearchSortSpecification. The sort list is set to an empty list. User can specify the default Class for the attributes.
Parameters:
defaultClass - default Class for sort Attributes

SearchSortSpecification


public SearchSortSpecification()
Constructs a SearchSortSpecification, calls this(null).

SearchSortSpecification


public SearchSortSpecification(java.lang.String[] classes,
                               java.lang.String[] attributes,
                               boolean[] orders)
                        throws IfsException
Constructs a SearchSortSpecification. Initializes Sort list with specified attributes. Calls add(classes, attributes, orders)
Parameters:
classes - Classes for the sort Attributes
attributes - Sort Attributes
orders - Sort Order for each attribute, true implies ascending, false implies descending.
Throws:
IfsException - if adding sort Attributes fails.
Method Detail

add


public void add(java.lang.String[] sortClasses,
                java.lang.String[] sortAttributes,
                boolean[] sortOrders)
         throws IfsException
Add Attributes to sort list. Attributes are added to the end of the existing list. Calls add on each attribute in the list.
Parameters:
sortClasses - list of classes, each entry specifies the class of the corresponding entry in the attribute list.
sortAttributes - list of sort Attributes
sortOrders - order of sorting attribute, true implies ascending, false implies descending. If this null, then ascending is assumed for all attributes.
Throws:
IfsException - if operation fails

add


public void add(java.lang.String[] sortAttributes,
                boolean[] sortOrders)
         throws IfsException
Adds the unqualified attributes to the sort list. The default Class is assumed for these attributes. Calls add(null, sortAttributes, sortOrders)
Parameters:
sortAttributes - list of sort Attributes
sortOrders - order of sorting attribute
Throws:
IfsException - if operation fails
