RouteCompilerInterface
RouteCompilerInterface is the interface that all RouteCompiler classes must implement.

Table of Contents

REGEX_DELIMITER  = '#'
SEPARATORS  = '/,;.:-_~+*=@|'
This string defines the characters that are automatically considered separators in front of optional placeholders (with default and no static text following). Such a single separator can be left out together with the optional placeholder from matching and generating URLs.
compile()  : CompiledRoute
Compiles the current route instance.
compilePattern()  : array<string|int, mixed>
computeRegexp()  : string
Computes the regexp used to match a specific token. It can be static text or a subpattern.
determineStaticPrefix()  : string
Determines the longest static prefix possible for a route.
findNextSeparator()  : string
Returns the next static character in the Route pattern that will serve as a separator (or the empty string when none available).
transformCapturingGroupsToNonCapturings()  : string
