Detailed Description

This forms the basis of a wildcard selection mechanism, allowing a user to issue a sequence of commands like:

1. allow *.cc
2. allow *.h
3. disallow a*.h
4. allow ab*.h
5. disallow c*.cc

This sequence would yield the following results: Match("x.cc") –> true due to rule #1 Match("c.cc") –> false due to rule #5 which overrides rule #1 Match("y.h") –> true due to rule #2 Match("a.h") –> false due to rule #3 which overrides rule #2 Match("ab.h") –> true due to rule #4 which overrides rule #3 So order matters.

Member Function Documentation

void net_instaweb::WildcardGroup::Allow

(

const StringPiece &

wildcard

)

Add an expression to Allow, potentially overriding previous calls to Disallow.

void net_instaweb::WildcardGroup::Disallow

(

const StringPiece &

wildcard

)

Add an expression to Disallow, potentially overriding previous calls to Allow.

bool net_instaweb::WildcardGroup::Match	(	const StringPiece &	str,
		bool	allow_by_default
	)		const

Determines whether a string is allowed by the wildcard group. If none of the wildcards in the group matches, allow_by_default is returned.
