# Class: com.pnfsoftware.jeb.core.units.code.asm.decompiler.ast.COutputSink

This output sink is the recipient for the generation of a C\-like Abstract Syntax Tree \(AST\). The sink also contains configuration elements that will guide and determine how certain AST elements are to be generated. A sink receives the output for a class, a field, or a method element. 

 Generating an AST yields a special type of elements, called items, that a UI client may want to track to achieve higher level functions such as syntax coloration.
