All Implemented Interfaces:

java.lang.Cloneable

public class Concat
extends Task

This class contains the 'concat' task, used to concatenate a series of files into a single stream. The destination of this stream may be the system console, or a file. The following is a sample invocation:

 <concat destfile="${build.dir}/index.xml"
   append="false">

   <fileset dir="${xml.root.dir}"
     includes="*.xml" />

 </concat>

Constructor Detail

Concat

public Concat()

Construct a new Concat task.

Method Detail

reset

public void reset()

Reset state to default.

setDestfile

public void setDestfile(java.io.File destinationFile)

Sets the destination file, or uses the console if not specified.

Parameters:

destinationFile - the destination file

setAppend

public void setAppend(boolean append)

Sets the behavior when the destination file exists. If set to true the stream data will be appended to the existing file, otherwise the existing file will be overwritten. Defaults to false.

Parameters:

append - if true append to the file.

setEncoding

public void setEncoding(java.lang.String encoding)

Sets the character encoding

Parameters:

encoding - the encoding of the input stream and unless outputencoding is set, the outputstream.

setOutputEncoding

public void setOutputEncoding(java.lang.String outputEncoding)

Sets the character encoding for outputting

Parameters:

outputEncoding - the encoding for the output file

Since:

Ant 1.6

setForce

public void setForce(boolean force)

Force overwrite existing destination file

Parameters:

force - if true always overwrite, otherwise only overwrite if the output file is older any of the input files.

Since:

Ant 1.6

createPath

public Path createPath()

Path of files to concatenate.

Returns:

the path used for concatenating

Since:

Ant 1.6

addFileset

public void addFileset(FileSet set)

Set of files to concatenate.

Parameters:

set - the set of files

addFilelist

public void addFilelist(FileList list)

List of files to concatenate.

Parameters:

list - the list of files

add

public void add(ResourceCollection c)

Add an arbitrary ResourceCollection.

Parameters:

c - the ResourceCollection to add.

Since:

Ant 1.7

addFilterChain

public void addFilterChain(FilterChain filterChain)

Adds a FilterChain.

Parameters:

filterChain - a filterchain to filter the concatenated input

Since:

Ant 1.6

addText

public void addText(java.lang.String text)

This method adds text which appears in the 'concat' element.

Parameters:

text - the text to be concated.

addHeader

public void addHeader(Concat.TextElement headerToAdd)

Add a header to the concatenated output

Parameters:

headerToAdd - the header

Since:

Ant 1.6

addFooter

public void addFooter(Concat.TextElement footerToAdd)

Add a footer to the concatenated output

Parameters:

footerToAdd - the footer

Since:

Ant 1.6

setFixLastLine

public void setFixLastLine(boolean fixLastLine)

Append line.separator to files that do not end with a line.separator, default false.

Parameters:

fixLastLine - if true make sure each input file has new line on the concatenated stream

Since:

Ant 1.6

setEol

public void setEol(FixCRLF.CrLf crlf)

Specify the end of line to find and to add if not present at end of each input file. This attribute is used in conjunction with fixlastline.

Parameters:

crlf - the type of new line to add - cr, mac, lf, unix, crlf, or dos

Since:

Ant 1.6

setWriter

public void setWriter(java.io.Writer outputWriter)

Set the output writer. This is to allow concat to be used as a nested element.

Parameters:

outputWriter - the output writer.

Since:

Ant 1.6

setBinary

public void setBinary(boolean binary)

Set the binary attribute. If true, concat will concatenate the files byte for byte. This mode does not allow any filtering or other modifications to the input streams. The default value is false.

Parameters:

binary - if true, enable binary mode.

Since:

Ant 1.6.2

execute

public void execute()

Execute the concat task.

Overrides:

execute in class Task
