Detailed Description

Build a CharReader implementation.

Deprecated:

This is experimental and will be altered before the next release.

Usage:

  using namespace Json;
  CharReaderBuilder builder;
  builder.settings_["collectComments"] = false;
  Value value;
  std::string errs;
  bool ok = parseFromStream(builder, std::cin, &value, &errs);

Public Member Functions
	CharReaderBuilder ()
virtual	~CharReaderBuilder ()
virtual CharReader *	newCharReader () const
bool	validate (JB_Json::Value *invalid) const
	Returns: true if 'settings' are legal and consistent; otherwise, indicate bad settings via 'invalid'.
Static Public Member Functions
static void	setDefaults (JB_Json::Value *settings)
	Called by ctor, but you can use this to reset settings_.
static void	strictMode (JB_Json::Value *settings)
	Same as old Features::strictMode().
Public Attributes
JB_Json::Value	settings_
	Configuration of this builder.

Member Function Documentation

CharReader * newCharReader

(

)

const [virtual]

Allocate a CharReader via operator new().

Exceptions:

std::exception

if something goes wrong (e.g. invalid settings)

Implements CharReader::Factory.

bool validate

(

JB_Json::Value *

invalid

)

const

Returns:

true if 'settings' are legal and consistent; otherwise, indicate bad settings via 'invalid'.

void setDefaults

(

JB_Json::Value *

settings

)

[static]

Called by ctor, but you can use this to reset settings_.

Precondition:

'settings' != NULL (but JB_Json::null is fine)

Remarks:

Defaults: src/lib_json/json_reader.cpp CharReaderBuilderStrictMode

void strictMode

(

JB_Json::Value *

settings

)

[static]

Same as old Features::strictMode().

Precondition:

'settings' != NULL (but JB_Json::null is fine)

Member Data Documentation

JB_Json::Value settings_

Configuration of this builder.

These are case-sensitive. Available settings (case-sensitive):

• `"collectComments": false or true`
  • true to collect comment and allow writing them back during serialization, false to discard comments. This parameter is ignored if allowComments is false.
• `"allowComments": false or true`
  • true if comments are allowed.
• `"strictRoot": false or true`
  • true if root must be either an array or an object value
• `"allowDroppedNullPlaceholders": false or true`
  • true if dropped null placeholders are allowed. (See StreamWriterBuilder.)
• `"allowNumericKeys": false or true`
  • true if numeric object keys are allowed.
• `"stackLimit": integer`
  • Exceeding stackLimit (recursive depth of `readValue()`) will cause an exception.
  • This is a security issue (seg-faults caused by deeply nested JSON), so the default is low.
• `"failIfExtra": false or true`
  • If true, `parse()` returns false when extra non-whitespace trails the JSON value in the input string.

You can examine 'settings_` yourself to see the defaults. You can also write and read them just like any JSON Value.
