- PadLeft(label, desiredLength, paddingChar) prepends the paddingChar (or the default value '_' if a paddingChar is not provided) to the label string until desiredLength is reached. - PadRight(label, desiredLength, paddingChar) appends the paddingChar (or the default value '_' if a paddingChar is not provided) to the label string until desiredLength is reached. Added Apache license disclaimers checkstyle fixes Replaced functional interface with abstract method Fixes and Further test cases: - Returns null if the input string is null - Returns a string full of padding if the input string is empty wip support padding string In order to be consistent with the feature introduced in #3615, RecordPath padLeft and padRight supports String padding. Since nifi-record-path doesn't have the Apache Commons StringUtils dependency, the padding methods have been added to the available NiFi commons StringUtils class. NIFI-6502 Updated top level NOTICE file to include citation for code borrowed from commons-lang3. borrowed pad methods from lang3 StringUtils Replaced `PadLeft` and `PadRight` record path functions with borrowed Apache Lang `StringUtils` padding methods and updated `nifi-assembly/NOTICE` accordingly This closes #3613 Signed-off-by: Mike Thomsen <mthomsen@apache.org> |

Features
Apache NiFi was made for dataflow. It supports highly configurable directed graphs of data routing, transformation, and system mediation logic. Some of its key features include:
- Web-based user interface
- Seamless experience for design, control, and monitoring
- Highly configurable
- Loss tolerant vs guaranteed delivery
- Low latency vs high throughput
- Dynamic prioritization
- Flows can be modified at runtime
- Back pressure
- Data Provenance
- Track dataflow from beginning to end
- Designed for extension
- Build your own processors and more
- Enables rapid development and effective testing
- Secure
- SSL, SSH, HTTPS, encrypted content, etc...
- Pluggable role-based authentication/authorization
Getting Started
To start NiFi:
- [linux/osx] execute bin/nifi.sh start
- [windows] execute bin/run-nifi.bat
- Direct your browser to http://localhost:8080/nifi/

Export Control
This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.
The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
The following provides more details on the included cryptographic software:
Apache NiFi uses BouncyCastle, Jasypt, JCraft Inc., and the built-in java cryptography libraries for SSL, SSH, and the protection of sensitive configuration parameters. See http://bouncycastle.org/about.html http://www.jasypt.org/faq.html http://jcraft.com/c-info.html http://www.oracle.com/us/products/export/export-regulations-345813.html for more details on each of these libraries cryptography features.
