Function Documentation

static std::string Json::codePointToUTF8 ( unsigned int  cp)
inlinestatic

Converts a unicode code-point to UTF-8.

Definition at line 13087 of file pyne.cc.

static bool Json::containsControlCharacter ( const char *  str)

Definition at line 16093 of file pyne.cc.

static bool Json::containsNewLine ( Reader::Location  begin,
Reader::Location  end 
)
static

Definition at line 13227 of file pyne.cc.

static char* Json::duplicateStringValue ( const char *  value,
unsigned int  length = unknown 
)
inlinestatic

Duplicates the specified string value.

Parameters
valuePointer to the string to duplicate. Must be zero-terminated if length is "unknown".
lengthLength of the value. if equals to unknown, then it will be computed using strlen(value).
Returns
Pointer on the duplicate instance of string.

)
inlinestatic

Definition at line 13221 of file pyne.cc.

static bool Json::isControlCharacter ( char  ch)
inlinestatic

Returns true if ch is a control character (in range [0,32[).

Definition at line 13118 of file pyne.cc.

std::ostream & Json::operator<< ( std::ostream &  ,
const Value root 
)

Output using the StyledStreamWriter.

See also
Json::operator>>()

Definition at line 16810 of file pyne.cc.

std::istream & Json::operator>> ( std::istream &  ,
Value  
)

Read from 'sin' into 'root'.

Always keep comments from the input JSON.

This can be used to read a file into a particular sub-object. For example:

cin >> root["dir"]["file"];
cout << root;

Result:

{
"dir": {
    "file": {
    // The input stream JSON would be nested here.
    }
}
}
Exceptions
std::exceptionon parse error.

static void Json::releaseStringValue ( char *  value)
inlinestatic

Free the string duplicated by duplicateStringValue().

Definition at line 14453 of file pyne.cc.

static void Json::uintToString ( LargestUInt  value,
char *&  current 
)
inlinestatic

Converts an unsigned integer to string.

Parameters
valueUnsigned interger to convert to string
currentInput/Output string buffer. Must have at least uintToStringBufferSize chars free.
