Member Function Documentation

handleValue()

template<>

void handleValue ( std::istream &  istr, JSONtree &  dst, const std::string &  key  )

inline

RECURSION

readTree()

template<class T >

void readTree ( T &  tree, std::istream &  istr  )

static

Reads and parses a JSON file.

Template Parameters

-	tree type, especially drain::Tree<K,V>

readValue()

void readValue ( const std::string &  s, Castable &  v, bool  keepType = false  )

static

Read value (JSON syntax). Read stream until a value has been extracted, with type recognition.

Allowed syntax:

• string: "<value>"
• scalar:

• array: [

,

,

,<...>]

treeToStream()

template<class T >

std::ostream & treeToStream ( std::ostream &  ostr, const T &  tree, const drain::SprinterLayout &  layout = drain::Sprinter::jsonLayout, short  indent = 0  )

static

Write a tree into an output stream using JSON layout by default.

SprinterLayout offers flexibility in formatting. JSON layout is the default.
