UnbufferedTokenStream Class

Initializes a new instance of the UnbufferedTokenStream class

Size of entire stream is unknown; we only know buffer size from FastQueue

Return element {@code i} elements ahead of current element. {@code i==0} gets current element. This is not an absolute index into {@link #data} since {@code p} defines the start of the real list.

How deep have we gone?

Get and remove first element in queue; override {@link FastQueue#remove()}; it's the same, just checks for backtracking.

Determines whether the specified object is equal to the current object.

add n elements to buffer

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Serves as the default hash function.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Seek to a 0-indexed absolute token index. Normally used to seek backwards in the buffer. Does not force loading of nodes.

Make sure we have 'need' elements from current position p. Last valid p index is data.size()-1. p+need-1 is the data index 'need' elements ahead. If we need 1 element, (p+1-1)==p must be < data.size().

Return string of current buffer contents; non-destructive
