Feature #3450
Updated by Alex Afanasyev almost 9 years ago
The `is*` methods are needed in many cases in order to avoid awkward checks that rely on exceptions:
```
/**
* @brief Check if the component is nonNegativeInteger
* @see http://named-data.net/doc/ndn-tlv/tlv.html#non-negative-integer-encoding
*/
bool
isNumber() const;
/**
* @brief Check if the component is NameComponentWithMarker per NDN naming conventions
* @see http://named-data.net/doc/tech-memos/naming-conventions.pdf
*/
bool
isNumberWithMarker(uint8_t marker) const;
/**
* @brief Check if the component is version per NDN naming conventions
* @see http://named-data.net/doc/tech-memos/naming-conventions.pdf
*/
bool
isVersion() const;
/**
* @brief Check if the component is segment number per NDN naming conventions
* @see http://named-data.net/doc/tech-memos/naming-conventions.pdf
*/
bool
isSegment() const;
/**
* @brief Check if the component is segment offset per NDN naming conventions
* @see http://named-data.net/doc/tech-memos/naming-conventions.pdf
*/
bool
isSegmentOffset() const;
/**
* @brief Check if the component is timestamp per NDN naming conventions
* @see http://named-data.net/doc/tech-memos/naming-conventions.pdf
*/
bool
isTimestamp() const;
/**
* @brief Check if the component is sequence number per NDN naming conventions
* @see http://named-data.net/doc/tech-memos/naming-conventions.pdf
*/
bool
isSequenceNumber() const;
/**
* @brief Check if the component is GenericComponent
*/
bool
isGeneric() const;
/**
* @brief Check if the component is ImplicitSha256DigestComponent
*/
bool
