Constructor Summary
`Mapper(Project p)` Construct a new `Mapper` element.

Method Summary
`void` `add(FileNameMapper fileNameMapper)` Add a nested `FileNameMapper`.
`void` `addConfigured(FileNameMapper fileNameMapper)` Cannot mix add and addconfigured in same type, so provide this to override the add method.
`void` `addConfiguredMapper(Mapper mapper)` Add a Mapper
`Path` `createClasspath()` Set the classpath to load the FileNameMapper through (nested element).
`FileNameMapper` `getImplementation()` Returns a fully configured FileNameMapper implementation.
`protected java.lang.Class` `getImplementationClass()` Gets the Class object associated with the mapper implementation.
`protected Mapper` `getRef()` Deprecated. since Ant 1.7.1 because a mapper might ref a FileNameMapper implementation directly.
`void` `setClassname(java.lang.String classname)` Set the class name of the FileNameMapper to use.
`void` `setClasspath(Path classpath)` Set the classpath to load the FileNameMapper through (attribute).
`void` `setClasspathRef(Reference ref)` Set the classpath to load the FileNameMapper through via reference (attribute).
`void` `setFrom(java.lang.String from)` Set the argument to FileNameMapper.setFrom
`void` `setRefid(Reference r)` Make this Mapper instance a reference to another Mapper.
`void` `setTo(java.lang.String to)` Set the argument to FileNameMapper.setTo
`void` `setType(Mapper.MapperType type)` Set the type of `FileNameMapper` to use.

Constructor Detail

### Mapper

    public Mapper(Project p)

  Construct a new `Mapper` element.

  Parameters:
    `p` - the owning Ant `Project`.

Method Detail

### setType

    public void setType(Mapper.MapperType type)

  Set the type of `FileNameMapper` to use.

  Parameters:
    `type` - the `MapperType` enumerated attribute.

### addConfigured

    public void addConfigured(FileNameMapper fileNameMapper)

  Cannot mix add and addconfigured in same type, so provide this to override the add method.

  Parameters:
    `fileNameMapper` - the `FileNameMapper` to add.

### add

    public void add(FileNameMapper fileNameMapper)

  Add a nested `FileNameMapper`.

  Parameters:
    `fileNameMapper` - the `FileNameMapper` to add.

### addConfiguredMapper

    public void addConfiguredMapper(Mapper mapper)

  Add a Mapper

  Parameters:
    `mapper` - the mapper to add

### setClassname

    public void setClassname(java.lang.String classname)

  Set the class name of the FileNameMapper to use.

  Parameters:
    `classname` - the name of the class

### setClasspath

    public void setClasspath(Path classpath)

  Set the classpath to load the FileNameMapper through (attribute).

  Parameters:
    `classpath` - the classpath

### createClasspath

    public Path createClasspath()

  Set the classpath to load the FileNameMapper through (nested element).

  Returns:
    a path object to be configured

### setClasspathRef

    public void setClasspathRef(Reference ref)

  Set the classpath to load the FileNameMapper through via reference (attribute).

  Parameters:
    `ref` - the reference to the FileNameMapper

### setFrom

    public void setFrom(java.lang.String from)

  Set the argument to FileNameMapper.setFrom

  Parameters:
    `from` - the from attribute to pass to the FileNameMapper

### setTo

    public void setTo(java.lang.String to)

  Set the argument to FileNameMapper.setTo

  Parameters:
    `to` - the to attribute to pass to the FileNameMapper

### setRefid

    public void setRefid(Reference r)
                  throws BuildException

  Make this Mapper instance a reference to another Mapper.

  You must not set any other attribute if you make it a reference.

  Overrides:
    `setRefid` in class `DataType`
  Parameters:
    `r` - the reference to another mapper
  Throws:
    `BuildException` - if other attributes are set

### getImplementation

    public FileNameMapper getImplementation()
                                     throws BuildException

  Returns a fully configured FileNameMapper implementation.

  Returns:
    a FileNameMapper object to be configured
  Throws:
    `BuildException` - on error

### getImplementationClass

    protected java.lang.Class getImplementationClass()
                                              throws java.lang.ClassNotFoundException

  Gets the Class object associated with the mapper implementation.

  Returns:
    `Class`.
  Throws:
    `java.lang.ClassNotFoundException` - if the class cannot be found

### getRef

    protected Mapper getRef()

  Deprecated. since Ant 1.7.1 because a mapper might ref a FileNameMapper implementation directly.

  Performs the check for circular references and returns the referenced Mapper.

  Returns:
    the referenced Mapper
