Class Assert

java.lang.Object

org.apache.tools.ant.ProjectComponent

org.apache.tools.ant.Task

net.sf.antcontrib.logic.Assert

All Implemented Interfaces:

java.lang.Cloneable, org.apache.tools.ant.TaskContainer

public class Assert
extends org.apache.tools.ant.Task
implements org.apache.tools.ant.TaskContainer

Based on the Sequential task. Similar to Java's 'assert' keyword, verifies that a given property has a given value. Throws a BuildException if the property value is not as expected or the property does not exist.

Also like Java's 'assert' keyword, the Assert task must be 'turned on' using the property "ant.enable.asserts". If not set, or is set to false, the Assert task works exactly like the Sequential task.

Can hold other tasks including Assert. Attributes:

• name - the name of a property. Required.
• exists - boolean, if true, throws BuildException if the property does not exist. Optional, default is true.
• value - the expected value of a property. Implies 'exists'. Throws BuildException if the actual value is not the same as this value. Optional.
• execute - boolean, if true, execute any contained tasks. Optional, default is true. Can also be set globally by setting the value of "assert.execute" to true or false. The local setting overrides the global setting.

The assert task supports a single nested BooleanCondition task, otherwise, the assert task does not support any nested elements apart from Ant tasks. Any valid Ant task may be embedded within the assert task.

Developed for use with Antelope, migrated to ant-contrib Oct 2003.

Method Detail

setName

public void setName(java.lang.String name)

Set the name of the property to test. Required.

Parameters:

name - the name of the property to test.

setValue

public void setValue(java.lang.String value)

Set the expected value of the property. Implies 'exists'. Throws BuildException if the actual value is not the same as this value. Optional.

Parameters:

value - the expected value of the property.

setMessage

public void setMessage(java.lang.String msg)

setExists

public void setExists(java.lang.String exists)

Set the 'exists' attribute. If true, throws BuildException if the property does not exist. Optional, default is true.

Parameters:

exists - Ant boolean, whether the value must exist.

setExecute

public void setExecute(java.lang.String execute)

Ant boolean, if true, execute any contained tasks. Optional, default is true. Can also be set globally by setting the value of "assert.execute" to true or false. The local setting overrides the global setting.

Parameters:

execute - Ant boolean, whether to execute contained tasks.

setFailonerror

public void setFailonerror(java.lang.String fail)

Ant boolean, stop the build process if the assertion fails. Defaults to true. Setting this to false is contrary to the intented use of assertions, but may be useful in certain situations.

Parameters:

fail - Ant boolean, whether to stop the build on assertion error.

maybeConfigure

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

Override maybeConfigure in a way that leaves the nested tasks unconfigured until they get executed.

Overrides:

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

Throws:

org.apache.tools.ant.BuildException

Since:

Ant 1.5

addTask

public void addTask(org.apache.tools.ant.Task task)

Add a nested task to execute.

Specified by:

addTask in interface org.apache.tools.ant.TaskContainer

Parameters:

task - Nested task to execute.

addBool

public void addBool(BooleanConditionTask boolTask)

execute

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

Execute this task and all nested Tasks.

Overrides:

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

Throws:

org.apache.tools.ant.BuildException

runTests

public static int runTests()

main

public static void main(java.lang.String[] args)
