Class TemplateSource

java.lang.Object

com.mitchellbosecke.pebble.lexer.TemplateSource

All Implemented Interfaces:

CharSequence

public class TemplateSource
extends Object
implements CharSequence

An implementation of CharSequence that is tuned to be used specifically by LexerImpl. It is possible to advance through the sequence without allocating a copy and it is possible to perform regex matches from the logical beginning of the remaining un-tokenized source. This class will also standardize newline characters from different architectures.
