Detailed Description

declares the set of Interests a producer can serve, which starts with a name prefix, plus an optional regular expression

Definition at line 35 of file interest-filter.hpp.

Constructor & Destructor Documentation

ndn::InterestFilter::InterestFilter

(

const Name &

prefix

)

Construct an InterestFilter to match Interests by prefix.

This filter matches Interests whose name start with the given prefix.

Note

InterestFilter is implicitly convertible from Name.

Definition at line 27 of file interest-filter.cpp.

ndn::InterestFilter::InterestFilter

(

const char *

prefixUri

)

Construct an InterestFilter to match Interests by prefix.

This filter matches Interests whose name start with the given prefix.

Parameters

prefixUri

name prefix, interpreted as ndn URI

Note

InterestFilter is implicitly convertible from null-terminated byte string.

Definition at line 32 of file interest-filter.cpp.

ndn::InterestFilter::InterestFilter

(

const std::string &

prefixUri

)

Construct an InterestFilter to match Interests by prefix.

This filter matches Interests whose name start with the given prefix.

Parameters

prefixUri

name prefix, interpreted as ndn URI

Note

InterestFilter is implicitly convertible from std::string.

Definition at line 37 of file interest-filter.cpp.

ndn::InterestFilter::InterestFilter	(	const Name &	prefix,
		const std::string &	regexFilter
	)

Construct an InterestFilter to match Interests by prefix and regular expression.

This filter matches Interests whose name start with the given prefix and the remaining components match the given regular expression. For example, the following InterestFilter:

InterestFilter("/hello", "<world><>+")

matches Interests whose name has prefix /hello followed by component world and has at least one more component after it, such as:

/hello/world/%21 /hello/world/x/y/z

Note that regular expression will need to match all components (e.g., there are implicit heading ^ and trailing $ symbols in the regular expression).

Member Function Documentation

bool ndn::InterestFilter::doesMatch

(

const Name &

name

)

const

Check if specified Interest name matches the filter.

Definition at line 58 of file interest-filter.cpp.

const Name& ndn::InterestFilter::getPrefix ( ) const

Definition at line 111 of file interest-filter.hpp.

const RegexPatternListMatcher& ndn::InterestFilter::getRegexFilter ( ) const

Definition at line 123 of file interest-filter.hpp.

bool ndn::InterestFilter::hasRegexFilter ( ) const

inline

Definition at line 117 of file interest-filter.hpp.

ndn::InterestFilter::operator const Name &

(

)

const

Implicit conversion to Name.

Note

This allows InterestCallback to be declared with Name rather than InterestFilter, but this does not work if InterestFilter has regular expression.
