java.lang.Object

org.mapfish.print.processor.AbstractProcessor<JasperReportBuilder.Input,java.lang.Void>

org.mapfish.print.processor.jasper.JasperReportBuilder

All Implemented Interfaces:

ConfigurationObject, HasConfiguration, Processor<JasperReportBuilder.Input,java.lang.Void>

public final class JasperReportBuilder
extends AbstractProcessor<JasperReportBuilder.Input,java.lang.Void>
implements HasConfiguration

A processor that actually compiles a JasperReport template file.

Example

     processors:
         - !reportBuilder # compile all reports in current directory
               directory: '.'

Method Detail

execute

public java.lang.Void execute(JasperReportBuilder.Input param,
                              Processor.ExecutionContext context)
                       throws net.sf.jasperreports.engine.JRException

Description copied from interface: Processor

Perform the process on the input attributes.

Specified by:

execute in interface Processor<JasperReportBuilder.Input,java.lang.Void>

Parameters:

param - A Java object whose public fields are populated from the Values object (which is used for transferring properties between processors).

context - The execution context for a print task.

Returns:

A Java object whose public fields will be put into the Values object. The key in the Values object is the name of the field or if there is a mapping in the Processor.getOutputMapperBiMap() map, the mapped name. The key is determined in a similar way as for the input object.

Throws:

net.sf.jasperreports.engine.JRException

createInputParameter

public JasperReportBuilder.Input createInputParameter()

Description copied from interface: Processor

Returns a new/clean instance of a parameter object. This instance's will be inspected using reflection to find its public fields and the properties will be set from the Values object.

The way the properties will be looked up is to

1. take the bean property name
2. map it using the input mapper, (if the input mapper does not have a mapping for the property then the unmapped property name is used)
3. Look up the property value in the Values object using the mapped property name
4. set the value on the instance created by this method. If the value is null an exception will be thrown UNLESS the HasDefaultValue annotation is on the field for the property.

The populated instance will be passed to the execute method. It is imperative that a new instance is created each time because they will be used in a multi-threaded environment and thus the same processor instance may be ran in multiple threads with different instances of the parameter object.

It is important to realize that super classes will also be analyzed, so care must be had with inheritance.

Specified by:

createInputParameter in interface Processor<JasperReportBuilder.Input,java.lang.Void>

setDirectory

public void setDirectory(java.lang.String directory)

Set the directory and test that the directory exists and is contained within the Configuration directory.

Parameters:

directory - the new directory

setConfiguration

public void setConfiguration(Configuration configuration)

Description copied from interface: HasConfiguration

Set the configuration that the object belongs to.

Specified by:

setConfiguration in interface HasConfiguration

Parameters:

configuration - the configuration object

toString

public java.lang.String toString()

Overrides:

toString in class AbstractProcessor<JasperReportBuilder.Input,java.lang.Void>

extraValidation

protected void extraValidation(java.util.List<java.lang.Throwable> validationErrors,
                               Configuration config)

Description copied from class: AbstractProcessor

Perform any extra validation a subclass may need to perform.

Specified by:

extraValidation in class AbstractProcessor<JasperReportBuilder.Input,java.lang.Void>

Parameters:

validationErrors - a list to add errors to so that all validation errors are reported as one.

config - the containing configuration
