◆ deref()

Value & Json::ValueIteratorBase::deref ( ) const
protected

Definition at line 26 of file json_valueiterator.inl.

◆ increment()

void Json::ValueIteratorBase::increment ( )
protected

Definition at line 30 of file json_valueiterator.inl.

◆ index()

UInt Json::ValueIteratorBase::index ( ) const

Return the index of the referenced Value, or -1 if it is not an arrayValue.

Definition at line 88 of file json_valueiterator.inl.

◆ isEqual()

bool Json::ValueIteratorBase::isEqual ( const SelfType other) const
protected

Definition at line 66 of file json_valueiterator.inl.

◆ key()

Value Json::ValueIteratorBase::key ( ) const

Return either the index or the member name of the referenced value as a Value.

Definition at line 78 of file json_valueiterator.inl.

◆ memberName() [1/2]

char const * Json::ValueIteratorBase::memberName ( ) const

Return the member name of the referenced Value.

"" if it is not an objectValue.

Deprecated:
This cannot be used for UTF-8 strings, since there can be embedded nulls.

Definition at line 103 of file json_valueiterator.inl.

Referenced by name().

+ Here is the caller graph for this function:

◆ memberName() [2/2]

char const * Json::ValueIteratorBase::memberName ( char const **  end) const

Return the member name of the referenced Value, or NULL if it is not an objectValue.

Note
Better version than memberName(). Allows embedded nulls.

Definition at line 108 of file json_valueiterator.inl.

◆ name()

JSONCPP_STRING Json::ValueIteratorBase::name ( ) const

Return the member name of the referenced Value, or "" if it is not an objectValue.

Note
Avoid c_str() on result, as embedded zeroes are possible.
