Class EvioEvent

java.lang.Object
  org.jlab.coda.jevio.BaseStructure
      org.jlab.coda.jevio.EvioBank
          org.jlab.coda.jevio.EvioEvent

All Implemented Interfaces:

java.lang.Cloneable, javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode, IEvioStructure, IEvioWriter

public class EvioEvent
extends EvioBank

An event is really just the outer, primary bank. That is, the first structure in an event (aka logical record, aka buffer) must be a bank, probably a bank of banks. The Event trivially extends bank, just so there can be a distinct EvioEvent class, for clarity.

Constructor Detail

EvioEvent

public EvioEvent()

Explicit null constructor for evio event.

EvioEvent

public EvioEvent(BankHeader bankHeader)

Constructor using a provided BankHeader.

Parameters:

bankHeader - the header to use.

See Also:

BankHeader

EvioEvent

public EvioEvent(int tag,
                 DataType dataType,
                 int num)

This is a general constructor to use for an EvioEvent.

Parameters:

tag - the tag for the event header (which is just a bank header).

dataType - the (enum) data type for the content of the bank.

num - sometimes, but not necessarily, an ordinal enumeration.

Method Detail

clone

public java.lang.Object clone()

Deep clone of BaseStructure does most of the work. Leave EvioBank's attachment as a reference. Only thing we need to do get rid of any cloned treeModel.

Overrides:

clone in class BaseStructure

hasDictionaryXML

public boolean hasDictionaryXML()

Is there an XML dictionary associated with this event?

Returns:

true if there is an XML dictionary associated with this event, else false

getDictionaryXML

public java.lang.String getDictionaryXML()

Get the XML dictionary associated with this event if there is one.

Returns:

the XML dictionary associated with this event if there is one, else null

setDictionaryXML

public void setDictionaryXML(java.lang.String dictionaryXML)

Set the XML dictionary associated with this event.

Parameters:

dictionaryXML - the XML dictionary associated with this event.

toString

public java.lang.String toString()

Create a string representation of the event.

Overrides:

toString in class BaseStructure

Returns:

a string representation of the event.

getTreeModel

public javax.swing.tree.DefaultTreeModel getTreeModel()

Get the tree model representing this event. This would have been generated as the event was being parsed.

Returns:

the tree model representing this event.

insert

public void insert(BaseStructure child,
                   BaseStructure parent)

Inserts a child structure into the event's JTree. This is called when the event is being parsed, and when an event is being created.

Parameters:

child - the child structure being added to the tree.

parent - the parent structure of the new child.

getEventNumber

public int getEventNumber()

This returns a number [1..] indicating which event this was in the event file from which it was read. It is not the "num" field from the header.

Returns:

a number [1..] indicating which event this was in the event file from which it was read.

setEventNumber

public void setEventNumber(int eventNumber)

This sets a number [1..] indicating which event this was in the event file from which it was read. It is not the "num" field from the header.

Parameters:

eventNumber - a number [1..] indicating which event this was in the event file from which it was read.

toXML

public void toXML(javax.xml.stream.XMLStreamWriter xmlWriter)

Write this event structure out as an XML record.

Overrides:

toXML in class EvioBank

Parameters:

xmlWriter - the writer used to write the events.

getXMLElementName

public java.lang.String getXMLElementName()

Get the element name for the bank for writing to XML.

Overrides:

getXMLElementName in class EvioBank

Returns:

the element name for the structure for writing to XML.
