Method Detail

addEntry

public void addEntry(Entry vEntry)
              throws IndexOutOfBoundsException

Parameters:

vEntry -

Throws:

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

addEntry

public void addEntry(int index,
                     Entry vEntry)
              throws IndexOutOfBoundsException

Parameters:

index -

vEntry -

Throws:

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

enumerateEntry

public Enumeration<Entry> enumerateEntry()

Method enumerateEntry.

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.

getEntry

public Entry getEntry(int index)
               throws IndexOutOfBoundsException

Method getEntry.

Parameters:

index -

Returns:

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

Throws:

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

getEntry

public Entry[] getEntry()

Method getEntry.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

getEntryCollection

public List<Entry> getEntryCollection()

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

Returns:

a reference to the Vector backing this class

getEntryCount

public int getEntryCount()

Method getEntryCount.

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

iterateEntry

public Iterator<Entry> iterateEntry()

Method iterateEntry.

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

removeAllEntry

public void removeAllEntry()

removeEntry

public boolean removeEntry(Entry vEntry)

Method removeEntry.

Parameters:

vEntry -

Returns:

true if the object was removed from the collection.

removeEntryAt

public Entry removeEntryAt(int index)

Method removeEntryAt.

Parameters:

index -

Returns:

the element removed from the collection

setEntry

public void setEntry(int index,
                     Entry vEntry)
              throws IndexOutOfBoundsException

Parameters:

index -

Throws:

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

setEntry

public void setEntry(Entry[] vEntryArray)

Parameters:

vEntryArray -

setEntry

public void setEntry(List<Entry> vEntryList)

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

Parameters:

vEntryList - the Vector to copy.

setEntryCollection

public void setEntryCollection(List<Entry> entryList)

Deprecated.

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

Parameters:

entryList - the Vector to set.

unmarshal

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

Method unmarshal.

Parameters:

reader -
