Interface QuasiPatternParser

All Known Implementing Classes:

QBuilder, SimpleQuasiParser

public interface QuasiPatternParser

Untamed: Given a template string in the language this quasi parser understands, parse it into a MatchMaker which will match objects of the form the template describes. The template language is a value description language augmented with $-holes and @-holes, representing values to be provided at runtime to the MatchMaker, or values for it to extract from the specimen, respectively.

Method Summary

MatchMaker	matchMaker(Twine template) Deprecated.
MatchMaker	matchMaker(Twine template, int[] dlrHoles, int[] atHoles) Enabled: For the i'th $-hole, dlrHoles[i] is the position of that hole in template, and the character at that position in template must be '$'.

Method Detail

matchMaker

public MatchMaker matchMaker(Twine template,
                             int[] dlrHoles,
                             int[] atHoles)

Enabled: For the i'th $-hole, dlrHoles[i] is the position of that hole in template, and the character at that position in template must be '$'. '$' characters that don't correspond to positions in dlrHoles are treated as part of the parser's normal language rather than indicating $-holes. Likewise for embedded '@' characters and positions in atHoles.

matchMaker

public MatchMaker matchMaker(Twine template)

Deprecated.

Enabled: In this old format, each $-hole is represented by a substring like '${3}' for $-hole number 3 (the fourth hole). Likewise for embedded '@' characters and positions in atHoles. '$' and '@' characters that are not holes must be doubled.
