Class SortDirectives

java.lang.Object

atg.repository.SortDirectives

All Implemented Interfaces:

atg.core.util.SortOrder, SortingConstants, java.util.Comparator

public class SortDirectives
extends java.lang.Object
implements atg.core.util.SortOrder, SortingConstants, java.util.Comparator

A structure representing a set of sorting directives. Contains an ordered list of SortDirective objects; the order of the objects implies the sorting order.

Sorting can be performed either by the Repository, through the executeQuery methods or as a post-processing step on the results. One can use the RepositorySorter class to sort an array of RepositoryItems.

SortDirective, RepositoryView.executeQuery(atg.repository.Query), RepositorySorter

Constructor Detail

SortDirectives

public SortDirectives()

Create a new instance.

SortDirectives

public SortDirectives(java.util.List<SortDirective> pDirectives)

Create a new instance with the specified directives. The Directives will be cloned into a new list.

Parameters:

pDirectives - to the

SortDirectives

public SortDirectives(SortDirective... pDirectives)

Create a SortDirectives instance with the specified directives.

Parameters:

pDirectives - the individual SortDirective instances to use.

Method Detail

copy

public SortDirectives copy()

Returns a deep copy of this object

isEmpty

public boolean isEmpty()

Returns true if there are no sort directives.

getNumDirectives

public int getNumDirectives()

Returns the number of sort directives.

getDirective

public SortDirective getDirective(int pIndex)

Returns the sort directive at the specified index.

addDirective

public void addDirective(SortDirective pDirective)

Adds the specified SortDirective to the end of the list of sort directives.

addDirective

public void addDirective(SortDirective pDirective,
                         int pIndex)

Adds the specified SortDirective at the specified index in the list of sort directives.

removeDirective

public void removeDirective(int pIndex)

Removes the sort directive at the specified index.

setCollator

public void setCollator(java.text.Collator pCollator)

Set property collator

Parameters:

pCollator - new value to set

getCollator

public java.text.Collator getCollator()

Get property collator

Returns:

collator

toString

public java.lang.String toString(java.lang.String pIndent)

Returns the string representation of the object, indenting the text using the specified pIndent string.

order

public int order(java.lang.Object pObject1,
                 java.lang.Object pObject2)

Compares two objects as Dynamic Beans, based on the sorting directives contained in this object. Returns an integer that is < 0 if pObject1 should come before pObject2, > 0 if pObject should come after pObject2, or = 0 if the order is indeterminate.

RepositorySorter uses this procedure to sort an array of RepositoryItems according to an order determined by a given SortDirectives object.

Specified by:

order in interface atg.core.util.SortOrder

See Also:

RepositoryItem, RepositorySorter.sort(atg.repository.RepositoryItem[], atg.repository.SortDirectives), RepositorySorter.compare(java.lang.Object, java.lang.Object, int, boolean)

compare

public int compare(java.lang.String pString1,
                   java.lang.String pString2)

Compare two Strings in a locale-sensitive manner if we have a Collator, otherwise using String.compareTo().

Parameters:

pString1 - first string to compare, cannot be null

pString2 - second string to compare, cannot be null

Returns:

an integer value less than zero if pString1 is less than pString2, zero if pString1 and pString2 are equal, greater than zero if pString1 is greater than pString2.

compare

public final int compare(java.lang.Object pObject1,
                         java.lang.Object pObject2)

Specified by:

compare in interface java.util.Comparator

hashCode

public int hashCode()

Return an integer hash code for this object

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code

equals

public boolean equals(java.lang.Object obj)

Returns true if the given SortDirectives has same number of elements as this one and each individual SortDirective object in the given SortDirectives equals (via its equals method) the corresponding SortDirective in this SortDirectives object. Otherwise, returns false.

Specified by:

equals in interface java.util.Comparator

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Returns the string representation of the object.

Overrides:

toString in class java.lang.Object
