android.gov.nist.core.GenericObjectList

All Implemented Interfaces:

Serializable, Cloneable, Iterable<GenericObject>, Collection<GenericObject>, Deque<GenericObject>, List<GenericObject>, Queue<GenericObject>

Direct Known Subclasses:

NetObjectList, SDPObjectList, SIPObjectList

public abstract class GenericObjectList
extends LinkedList<GenericObject>
implements Serializable, Cloneable

Implements a homogenous consistent linked list. All the objects in the linked list must derive from the same root class. This is a useful constraint to place on our code as this property is invariant.The list is created with the superclass which can be specified as either a class name or a Class.

Method Detail

getIndentation

protected String getIndentation()

isCloneable

protected static boolean isCloneable(Object obj)

Return true if this supports reflection based cloning.

isMySubclass

public static boolean isMySubclass(Class<?> other)

clone

public Object clone()

Makes a deep clone of this list.

Overrides:

clone in class LinkedList<GenericObject>

setMyClass

public void setMyClass(Class cl)

next

protected GenericObject next(ListIterator iterator)

Traverse the list given a list iterator

first

protected GenericObject first()

This is the default list iterator.This will not handle nested list traversal.

next

protected GenericObject next()

Fetch the next object from the list based on the default list iterator

concatenate

protected void concatenate(GenericObjectList objList)

Concatenate two compatible header lists, adding the argument to the tail end of this list.

Type Parameters:

var - topFlag set to true to add items to top of list

concatenate

protected void concatenate(GenericObjectList objList,
               boolean topFlag)

Concatenate two compatible header lists, adding the argument either to the beginning or the tail end of this list. A type check is done before concatenation.

Type Parameters:

var - topFlag set to true to add items to top of list else add them to the tail end of the list.

debugDump

public String debugDump()

Convert this list of headers to a formatted string.

debugDump

public String debugDump(int indent)

Convert this list of headers to a string (for printing) with an indentation given.

addFirst

public void addFirst(GenericObject objToAdd)

Specified by:

addFirst in interface Deque<GenericObject>

Overrides:

addFirst in class LinkedList<GenericObject>

mergeObjects

public void mergeObjects(GenericObjectList mergeList)

Do a merge of the GenericObjects contained in this list with the GenericObjects in the mergeList. Note that this does an inplace modification of the given list. This does an object by object merge of the given objects.

Parameters:

mergeList - is the list of Generic objects that we want to do an object by object merge with. Note that no new objects are added to this list.

encode

public String encode()

Encode the list in semicolon separated form.

Returns:

an encoded string containing the objects in this list.

Since:

v1.0

toString

public String toString()

Alias for the encode function above.

Overrides:

toString in class AbstractCollection<GenericObject>

hashCode

public int hashCode()

Hash code. We never expect to put this in a hash table so return a constant.

Specified by:

hashCode in interface Collection<GenericObject>

Specified by:

hashCode in interface List<GenericObject>

Overrides:

hashCode in class AbstractList<GenericObject>

equals

public boolean equals(Object other)

Equality checking predicate.

Specified by:

equals in interface Collection<GenericObject>

Specified by:

equals in interface List<GenericObject>

Overrides:

equals in class AbstractList<GenericObject>

Parameters:

other - is the object to compare ourselves to.

Returns:

true if the objects are equal.

match

public boolean match(Object other)

Match with a template (return true if we have a superset of the given template. This can be used for partial match (template matching of SIP objects). Note -- this implementation is not unnecessarily efficient :-)

Parameters:

other - template object to compare against.
