Constructor Details

TaggedComponentList

public TaggedComponentList()

TaggedComponentList

public TaggedComponentList(byte[] data)
Constructs a TaggedComponentList from a CDR encapsulation of an array of tagged components.


TaggedComponentList

public TaggedComponentList(InputStream in)
Constructs a TaggedComponentList object from a CDR representation of an array of tagged components.

Method Details

addAll

public void addAll(TaggedComponentList other)
Adds an entire TaggedComponentList to this list.


addComponent

public void addComponent(int tag,
                         Object data,
                         Class helper)
Adds a tagged component to this list. The component's data is created by marshaling the given data Object using the write() method of the given helper class.


addComponent

public void addComponent(int tag,
                         byte[] data)
Adds a tagged component to this list.


addComponent

public void addComponent(TaggedComponent component)
Adds a tagged component to this list.


asArray

public TaggedComponent[] asArray()


clone

public Object clone()
            throws CloneNotSupportedException


get

public TaggedComponent get(int index)


getComponent

public Object getComponent(int tag,
                           Class helper)
Searches for a component with the given tag in this component list. If one is found, this method reads the corresponding data with the given helper class, and returns the resulting object, otherwise returns null.


getComponents

public List getComponents(int tag,
                          Class helper)
Returns a List of all components with the given tag from this TaggedComponentList. Each individual component is read with the given helper class. If no components with the given tag can be found, an empty list is returned.


getStringComponent

public String getStringComponent(int tag)
Returns the first component with the given tag, which is assumed to be a CDR string. If no component with the given tag exists, returns null.


isEmpty

public boolean isEmpty()


size

public int size()
