Parser Function Component

The Parser FC wraps a Parser into an AssemblyLine Component, such that it can be inserted anywhere in the AssemblyLine data flow.

Multiple instances of Parser FCs could aid in decoding two or more layers of protocol.

Configuration

Operation Mode

Operation mode of the Parser: Read an Entry from parser, Write an Entry to parser (returning result)

Returns result as String

Check to have the function return a String object instead of a Bytearray object

Character Set

The character set to use if value is returned as String object. The default is UTF-8.

Detailed Log

When checked, generates additional log messages.

A Parser Function Component also has a Parser tab. Using the Parser tab, we can select and configure the Parser we want to use to interpret or generate data stream records.

Using the FC

This FC allows us to select a Parser and then set its mode to either input (Read) or output (Write).

In Read mode, provide an attribute (in the Output Map) called "value" which is either a string, a File, a Reader or a java.io.InputStream object to be used as input for the Parser. The FC will return an Entry object (conn) with the parsed attributes, which are then available for your Input Map.

In Write mode the FC takes an Entry with the attributes passed in by the Output Map and applies the Parser to that Entry, providing the return bytestream in the Attribute named "value". This Attribute is a java.lang.String if we select the Return result as String checkbox in the Config tab; otherwise it is a bytearray.
