Initial Code Fragment
This is the initial source code fragment in supported programming language that will undergo analysis. Essentially this is an example of the code that already solves the problem similar to yours and that is going to be examined to produce a pattern file.

Parameters
Parameters are passed to expressions

Expressions
Expressions are supplied to slots

Slots
Those are variable components of the pattern. For example the name of the class or method.

Insertion Points
Some places in a code fragment can be identified as Insertion Points for more extensive coding whose content is no longer covered by the pattern definition.

Code Blocks
Context dependencies in the existing code fragments are identified and enlisted through Code Blocks. Those blocks are named, and may be equipped with additional conditions - the Condition Expression

Condition Expressions
Condition Expressions may be passed to Code Blocks.

Code Pattern-File
This is the intermediate representation of the software patterns stored as an XML file that is available for expansion. Expansion is the process of generating target code from Code Pattern file.

Configuration File
During the expansion, the default parameter values are overwritten, or a configuration stored from a previous expansion is loaded from the Configuration File.

Expanded Pattern with Insertion Points
After expansion with the set values, the named insertion points visible in the generated code can be filled with further code.

Initialization Data
Initialization data is used to set values to slots and insertion points.

Target Code Fragment
This is the code fragment that was generated from the pattern to address your specific problem.
