Class Assertions

      org.apache.tools.ant.types.DataType
          org.apache.tools.ant.types.Assertions

All Implemented Interfaces:

java.lang.Cloneable

public class Assertions
extends DataType
implements java.lang.Cloneable

The assertion datatype. This type describes assertion settings for the <java> task and others. One can set the system assertions, and enable/disable those in packages and classes. Assertions can only be enabled or disabled when forking Java. Example: set system assertions and all org.apache packages except for ant, and the class org.apache.tools.ant.Main.

 <assertions enableSystemAssertions="true" >
   <enable package="org.apache" />
   <disable package="org.apache.ant" />
   <enable class="org.apache.tools.ant.Main"/>
 </assertions>

Disable system assertions; enable those in the anonymous package

 <assertions enableSystemAssertions="false" >
   <enable package="..." />
 </assertions>
 

enable assertions in a class called Test

 <assertions >
   <enable class="Test" />
 </assertions>
 

This type is a datatype, so you can declare assertions and use them later

 <assertions id="project.assertions" >
   <enable project="org.apache.test" />
 </assertions>

 <assertions refid="project.assertions" />

 

Since:

Ant 1.6

Method Detail

addEnable

public void addEnable(Assertions.EnabledAssertion assertion)

enable assertions

Parameters:

assertion - an enable assertion nested element

addDisable

public void addDisable(Assertions.DisabledAssertion assertion)

disable assertions

Parameters:

assertion - a disable assertion nested element

setEnableSystemAssertions

public void setEnableSystemAssertions(java.lang.Boolean enableSystemAssertions)

enable or disable system assertions. Default is not set (neither -enablesystemassersions or -disablesytemassertions are used on the command line).

Parameters:

enableSystemAssertions - if true enable system assertions

setRefid

public void setRefid(Reference ref)

Set the value of the refid attribute.

Subclasses may need to check whether any other attributes have been set as well or child elements have been created and thus override this method. if they do the must call super.setRefid.

Overrides:

setRefid in class DataType

Parameters:

ref - the reference to use

size

public int size()

how many assertions are made...will resolve references before returning

Returns:

total # of commands to make

applyAssertions

public void applyAssertions(java.util.List<java.lang.String> commandList)

add the assertions to a list in a format suitable for adding to a command line

Parameters:

commandList - the command line to format

applyAssertions

public void applyAssertions(CommandlineJava command)

apply all the assertions to the command.

Parameters:

command - the command line to format

applyAssertions

public void applyAssertions(java.util.ListIterator<java.lang.String> commandIterator)

add the assertions to a list in a format suitable for adding to a command line

Parameters:

commandIterator - list of commands

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

clone the objects. This is not a full depth clone; the list of assertions is cloned, but it does not clone the underlying assertions.

Overrides:

clone in class DataType

Returns:

a cli

Throws:

java.lang.CloneNotSupportedException - if the super class does not support cloning
