Detailed Description

base class for Value iterators.

Member Function Documentation

deref()

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

protected

Internal utility functions to assist with implementing other iterator functions. The const and non-const versions of the "deref" protected methods expose the protected current_ member variable in a way that can often be optimized away by the compiler.

index()

UInt Json::ValueIteratorBase::index

(

)

const

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

key()

Value Json::ValueIteratorBase::key

(

)

const

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

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.

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.

name()

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.
