Method Details
-
setTargetdir
public void setTargetdir(java.io.File targetdir)The name of the file or directory which is checked for out-of-date files.- Parameters:
targetdir
- the directory to scan looking for files.
-
createMapper
Defines the FileNameMapper to use (nested mapper element).- Returns:
- a mapper to be configured
- Throws:
BuildException
- if more than one mapper defined
-
addConfigured
Add a configured FileNameMapper instance.- Parameters:
fileNameMapper
- the FileNameMapper to add- Throws:
BuildException
- if more than one mapper defined- Since:
- Ant 1.8.0
-
verifySettings
public void verifySettings()Checks to make sure all settings are kosher. In this case, it means that the dest attribute has been set and we have a mapper.- Overrides:
verifySettings
in classBaseSelector
-
isSelected
public boolean isSelected(java.io.File basedir, java.lang.String filename, java.io.File file)The heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset.- Specified by:
isSelected
in interfaceFileSelector
- Specified by:
isSelected
in classBaseSelector
- Parameters:
basedir
- the base directory the scan is being done fromfilename
- is the name of the file to checkfile
- is a java.io.File object the selector can use- Returns:
- whether the file should be selected or not
-
selectionTest
protected abstract boolean selectionTest(java.io.File srcfile, java.io.File destfile)this test is our selection test that compared the file with the destfile- Parameters:
srcfile
- file to test; may be nulldestfile
- destination file- Returns:
- true if source file compares with destination file
-
setGranularity
public void setGranularity(int granularity)Sets the number of milliseconds leeway we will give before we consider a file out of date. Defaults to 2000 on MS-DOS derivatives and 1000 on others.- Parameters:
granularity
- the leeway in milliseconds
