Required properties
Properties
| inputEncoding | top |
The character encoding of the input file. Use this if the input file has a non-standard encoding, i.e. an encoding different from the Java virtual machine's (platform dependent) default charset.
- Setter method:
setInputEncoding(Charset c)
parameters:c– The input charset.- Setter method:
setInputEncoding(String s)
parameters:s– The name of a character encoding.- Default value:
- The platform's default encoding.
| logFooter | top |
The message that is logged to info level
after the task has been successfully run.
- Setter method:
setLogFooter(String s)
parameters:s– The footer message.- Default value:
- Empty (no footer message is logged.)

- logHeader
| logHeader | top |
The message that is logged to info level
before the task is run.
- Setter method:
setLogHeader(String s)

- A task class specific message.

- logFooter
| outputEncoding | top |
The character encoding of the output file. Use this if the output file should have a non-standard encoding, i.e. an encoding different from the Java virtual machine's (platform dependent) default charset.
- Setter method:
setOutputEncoding(Charset c)
parameters:c– The output charset.- Setter method:
setOutputEncoding(String s)
parameters:s– The name of a character encoding.- Default value:
- The platform's default encoding.

- target
| overwriteStrategy | top |
The overwrite strategy decides how the task will react if there already is an entity (file or directory) in a location where it wants to create a new entity.
If the strategy is to not overwrite existing entities, the task will fail when it cannot create the entities that it wants to create.
Non-empty directories are never overwritten, regardless of the chosen strategy.
- Setter method:
setOverwrite(boolean b)Setting this to a value ofparameters:truemeans that the DoOverwriteAndLogWarning strategy is used. A value of false gives the DontOverwriteAndThrowException strategy.b– Should an existing entity be overwritten?- Setter method:
setOverwriteStrategy(OverwriteStrategy strat)Set the overwrite strategy.parameters:strat– The overwrite strategy.- Default value:
- DontOverwriteAndThrowException

- target
| reportLevel | top |

- Setter method:
setReportLevel(Level l)Set the report levelparameters:l– The new report level.

* An EntityFS-aware task is implemented using EntityFS. This means that it uses the filter settings of DirectoryView:s and also that it often can work with other file system implementations than File-based, such as the RAM file system.
