RsaKeyParams carries parameters for RSA key.

Definition at line 199 of file key-params.hpp.

A scoped handle of registered Interest filter.

Upon destruction of this handle, the Interest filter is unset automatically. Most commonly, the application keeps a ScopedInterestFilterHandle as a class member field, so that it can cleanup its Interest filter when the class instance is destructed.

{
ScopedInterestFilterHandle hdl = face.setInterestFilter(prefix, onInterest);
} // hdl goes out of scope, unsetting the Interest filter
Warning
Unsetting the same Interest filter more than once, using same or different InterestFilterHandle or ScopedInterestFilterHandle, may trigger undefined behavior.
Unsetting an Interest filter after the face has been destructed may trigger undefined behavior.

Definition at line 685 of file face.hpp.

A scoped handle of pending Interest.

Upon destruction of this handle, the pending Interest is canceled automatically. Most commonly, the application keeps a ScopedPendingInterestHandle as a class member field, so that it can cleanup its pending Interest when the class instance is destructed.

{
ScopedPendingInterestHandle hdl = face.expressInterest(interest, satisfyCb, nackCb, timeoutCb);
} // hdl goes out of scope, canceling the pending Interest
Warning
Canceling the same pending Interest more than once, using same or different PendingInterestHandle or ScopedPendingInterestHandle, may trigger undefined behavior.
Canceling a pending Interest after the face has been destructed may trigger undefined behavior.

Definition at line 583 of file face.hpp.

A scoped handle of registered prefix.

Upon destruction of this handle, the prefix is unregistered automatically. Most commonly, the application keeps a ScopedRegisteredPrefixHandle as a class member field, so that it can cleanup its prefix registration when the class instance is destructed. The application will not be notified whether the unregistration was successful.

{
ScopedRegisteredPrefixHandle hdl = face.registerPrefix(prefix, onSuccess, onFailure);
} // hdl goes out of scope, unregistering the prefix
Warning
Unregistering the same prefix more than once, using same or different RegisteredPrefixHandle or ScopedRegisteredPrefixHandle, may trigger undefined behavior.
Unregistering a prefix after the face has been destructed may trigger undefined behavior.

std::string ndn::escape ( const std::string &  str)

Percent-encode a string.

See also
RFC 3986 section 2

This function will encode all characters that are not one of the following: ALPHA ("a" to "z" and "A" to "Z") / DIGIT (0 to 9) / "-" / "." / "_" / "~"

The hex encoding uses the numbers 0-9 and the uppercase letters A-F.

Examples:

escape("hello world") == "hello%20world"
escape("100%") == "100%25"

Block ndn::operator""_block ( const char *  input,
std::size_t  len 
)

Construct a Block from hexadecimal input.

Parameters
inputa string containing hexadecimal bytes and comments. 0-9 and upper-case A-F are input; all other characters are comments.
lenlength of input.
Exceptions
std::invalid_argumentinput is empty or has odd number of hexadecimal digits.
tlv::Errorinput cannot be parsed into valid Block.

Example

Block nameBlock = "0706 080141 080142"_block;
Block nackBlock = "FD032005 reason(no-route)=FD03210196"_block;

void ndn::printHex ( std::ostream &  os,
uint64_t  num,
bool  wantUpperCase = false 
)

Output the hex representation of num to the output stream os.

Parameters
osOutput stream
numNumber to print in hexadecimal format
wantUpperCaseif true, print uppercase hex chars; the default is to use lowercase

The output string is a continuous sequence of hex characters without any whitespace separators.

Definition at line 42 of file string-helper.cpp.

void ndn::printHex ( std::ostream &  os,
const uint8_t *  buffer,
size_t  length,
bool  wantUpperCase = true 
)

Output the hex representation of the bytes in buffer to the output stream os.

Parameters
osOutput stream
bufferPointer to an array of bytes
lengthSize of the array
wantUpperCaseif true (the default) print uppercase hex chars

Examples:

printHex(std::cout, "Hello, World!"); // outputs "48656C6C6F2C20776F726C6421"
printHex(std::cout, "Hello, World!", false); // outputs "48656c6c6f2c20776f726c6421"

Each octet is always represented as two hex characters ("00" for octet==0).

The output string is a continuous sequence of hex characters without any whitespace separators.
