jbreport.core
Class QueryBoundResult  

java.lang.Object
  jbreport.core.AbstractReportElement
      jbreport.core.QueryBoundResult

All Implemented Interfaces:

java.lang.Cloneable, jbreport.ReportElement, Traversable, XMLAware

---

class QueryBoundResult

extends AbstractReportElement

This is used to get a particular cell of data from the results of the query to the datasource. It would normally be used to present information during section breaks.

Version:

$Revision: 1.1 $

Field Summary
private  java.lang.String	id           The identifier of the query result column that we will bind to
private  java.lang.String	value           The current value of the bound element

 

Fields inherited from class jbreport.core.AbstractReportElement

Fields inherited from interface jbreport.ReportElement

DEEP, SHALLOW

 

Constructor Summary
(package private)	QueryBoundResult()

 

Method Summary
void	accept(ReportVisitor visitor, ReportVisitorState state)           This defines the operation that the Traversable instance must perform at each node in the traversal.
java.lang.String	getString(java.lang.String property, java.lang.String defaultValue)           Returns the string value for the requested property.
void	updateData(jbreport.data.QueryResult queryResult)           This is called for every successful next() method call on the QueryResult contained by a group.
void	xmlInitialize(java.lang.String localName, org.xml.sax.Attributes attributes)           This should initialize the instance with data obtained during the traversal of an xml tree.

Method Detail

accept

public void accept(ReportVisitor visitor,
                   ReportVisitorState state)
            throws jbreport.ReportException

Description copied from interface: Traversable

This defines the operation that the Traversable instance must perform at each node in the traversal. It should be coded such that it calls an appropriate method on the ReportVisitor instance. Should an appropriate method not exist, one should be coded.

The accept method should not recurse into its children, it is the contract of the iterator to perform that function.

eg:- For node type Section the method on this node should be as follows.

   public void accept(ReportVisitor visitor, ReportVisitorState state) 
      throws ReportException {
      visitor.visitSection(this, state);
   }

Specified by:

accept in interface Traversable

Overrides:

accept in class AbstractReportElement

getString

public java.lang.String getString(java.lang.String property,
                                  java.lang.String defaultValue)
                           throws jbreport.ReportException

Description copied from interface: jbreport.ReportElement

Returns the string value for the requested property.

Specified by:

getString in interface jbreport.ReportElement

Overrides:

getString in class AbstractReportElement

---

updateData

public void updateData(jbreport.data.QueryResult queryResult)
                throws jbreport.ReportException

Description copied from class: AbstractReportElement

This is called for every successful next() method call on the QueryResult contained by a group.

Overrides:

updateData in class AbstractReportElement

---

xmlInitialize

public void xmlInitialize(java.lang.String localName,
                          org.xml.sax.Attributes attributes)
                   throws jbreport.ReportException

Description copied from interface: jbreport.ReportElement

This should initialize the instance with data obtained during the traversal of an xml tree. The child-parent relationship is catered for with the xmlEndChild() method.

Specified by:

xmlInitialize in interface jbreport.ReportElement

Overrides:

xmlInitialize in class AbstractReportElement
