Method Detail

addV

public void addV(V vV)
          throws IndexOutOfBoundsException

Parameters:

vV -

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

addV

public void addV(int index,
                 V vV)
          throws IndexOutOfBoundsException

Parameters:

index -

vV -

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

enumerateV

public Enumeration<V> enumerateV()

Method enumerateV.

Returns:

an Enumeration over all possible elements of this collection

equals

public boolean equals(Object obj)

Overrides the java.lang.Object.equals method.

Overrides:

equals in class Object

Parameters:

obj -

Returns:

true if the objects are equal.

getT

public T getT()

Returns the value of field 't'.

Returns:

the value of field 'T'.

getV

public V getV(int index)
       throws IndexOutOfBoundsException

Method getV.

Parameters:

index -

Returns:

the value of the org.opennms.netmgt.jasper.rrdtool.V at the given index

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

getV

public V[] getV()

Method getV.Returns the contents of the collection in an Array.

Note: Just in case the collection contents are changing in another thread, we pass a 0-length Array of the correct type into the API call. This way we know that the Array returned is of exactly the correct length.

Returns:

this collection as an Array

getVCollection

public List<V> getVCollection()

Method getVCollection.Returns a reference to '_vList'. No type checking is performed on any modifications to the Vector.

Returns:

a reference to the Vector backing this class

getVCount

public int getVCount()

Method getVCount.

Returns:

the size of this collection

hashCode

public int hashCode()

Overrides the java.lang.Object.hashCode method.

The following steps came from Effective Java Programming Language Guide by Joshua Bloch, Chapter 3

Overrides:

hashCode in class Object

Returns:

a hash code value for the object.

isValid

public boolean isValid()

Method isValid.

Returns:

true if this object is valid according to the schema

iterateV

public Iterator<V> iterateV()

Method iterateV.

Returns:

an Iterator over all possible elements in this collection

marshal

public void marshal(Writer out)
             throws org.exolab.castor.xml.MarshalException,
                    org.exolab.castor.xml.ValidationException

Parameters:

out -

Throws:

org.exolab.castor.xml.MarshalException - if object is null or if any SAXException is thrown during marshaling

org.exolab.castor.xml.ValidationException - if this object is an invalid instance according to the schema

marshal

public void marshal(ContentHandler handler)
             throws IOException,
                    org.exolab.castor.xml.MarshalException,
                    org.exolab.castor.xml.ValidationException

Parameters:

handler -

Throws:

IOException - if an IOException occurs during marshaling

org.exolab.castor.xml.ValidationException - if this object is an invalid instance according to the schema

org.exolab.castor.xml.MarshalException - if object is null or if any SAXException is thrown during marshaling

removeAllV

public void removeAllV()

removeV

public boolean removeV(V vV)

Method removeV.

Parameters:

vV -

Returns:

true if the object was removed from the collection.

removeVAt

public V removeVAt(int index)

Method removeVAt.

Parameters:

index -

Returns:

the element removed from the collection

setT

public void setT(T t)

Sets the value of field 't'.

Parameters:

t - the value of field 't'.

setV

public void setV(int index,
                 V vV)
          throws IndexOutOfBoundsException

Parameters:

index -

vV -

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

setV

public void setV(V[] vVArray)

Parameters:

vVArray -

setV

public void setV(List<V> vVList)

Sets the value of '_vList' by copying the given Vector. All elements will be checked for type safety.

Parameters:

vVList - the Vector to copy.

setVCollection

public void setVCollection(List<V> vList)

Deprecated.

Sets the value of '_vList' by setting it to the given Vector. No type checking is performed.

Parameters:

vList - the Vector to set.

unmarshal

public static Row unmarshal(Reader reader)
                     throws org.exolab.castor.xml.MarshalException,
                            org.exolab.castor.xml.ValidationException

Method unmarshal.

Parameters:

reader -

Returns:

the unmarshaled org.opennms.netmgt.jasper.rrdtool.Row
