public class JRAntApiWriteTask
extends JRBaseAntTask

Ant task for batch-generating the Java source file that uses the JR API to create the report design, from compiled report template files or from source JRXML files. Works like the built-in javac Ant task.

This task can take the following arguments:

• src
• destdir

Of these arguments, the src and destdir are required. When this task executes, it will recursively scan the src and destdir looking for compiled report template files or for source JRXML report template files and it will recreate the Java source file for each of them. This task makes its file creation decision based on timestamp and only input files that have no corresponding file in the target directory or where the destination Java file is older than the input file will be processed.

Constructor Detail

JRAntApiWriteTask

public JRAntApiWriteTask()

Method Detail

setSrcdir

public void setSrcdir(org.apache.tools.ant.types.Path srcdir)

Sets the source directories to find the source files.

Parameters:

srcdir - source path

createSrc

public org.apache.tools.ant.types.Path createSrc()

Adds a path for source report templates.

Returns:

source path

setDestdir

public void setDestdir(File destdir)

Sets the destination directory into which the Java report design files should be generated.

Parameters:

destdir - destination directory

createClasspath

public org.apache.tools.ant.types.Path createClasspath()

Adds a path to the classpath.

Returns:

classpath to use when updating the report

setRunApi

public void setRunApi(boolean runApi)

If set to true, the task will run the API writer generated classes and produce JRXML source files.

execute

public void execute()
             throws org.apache.tools.ant.BuildException

Executes the task.

Overrides:

execute in class org.apache.tools.ant.Task

Throws:

org.apache.tools.ant.BuildException

checkParameters

protected void checkParameters()
                        throws org.apache.tools.ant.BuildException

Checks that all required attributes have been set and that the supplied values are valid.

Throws:

org.apache.tools.ant.BuildException

scanSrc

protected void scanSrc()
                throws org.apache.tools.ant.BuildException

Scans the source directories looking for source report design files to be processed.

Throws:

org.apache.tools.ant.BuildException

scanDir

protected void scanDir(File srcdir,
                       File destdir,
                       String[] files)

Scans the directory looking for source report design files to be processed. The results are returned in the instance variable reportFilesMap.

Parameters:

srcdir - source directory

destdir - destination directory

files - included file names

writeApi

protected void writeApi()
                 throws org.apache.tools.ant.BuildException

Performs the API code generation for the selected report design files.

Throws:

org.apache.tools.ant.BuildException

runApi

protected void runApi()
               throws org.apache.tools.ant.BuildException

Runs the generated code and produces the JRXML image of the report.

Throws:

org.apache.tools.ant.BuildException
