Enclosing class:

Parameters

public class Parameters.CharSequenceBuffer
extends java.lang.Object
implements java.lang.CharSequence

This class gathers up a stack of CharSequence objects and makes them look like a single CharSequence. The reason we do this is so that we can insert special, mutable CharSequences in here that are used as parameters. For example, suppose we have an input string like: ${path:/Users/trevor/Desktop}.txt We can make a CharSequenceBuffer = [ MutableCharSequence("path"), ".txt" ] Now, we can go and change the MutableCharSequence later so that parameters work appropriately.
