Detailed Description

Provides efficient way of accessing text-based FIX field values.

Constructor & Destructor Documentation

StringRef ( const StringRef &  other)

inline

Initializes as clone of other instance.

Data referenced by clone is not copied. Instead both instances will refer to same text segment.

Member Function Documentation

bool toNumber ( NumericType &  number) const

inline

Returns number if text is string representation of an integer.
