Constructor & Destructor Documentation

◆ Field() [1/2]

Field ( )

inline

Initializes a field with no value.

Definition at line 33 of file Field.h.

◆ Field() [2/2]

Field ( const ValueConverter & converter )

inlineexplicitprotectednoexcept

Initializes the field.

Definition at line 301 of file Field.h.

Member Function Documentation

◆ cast()

template<class Value>

ValueConversion< Value >::Result cast ( ) const

inline

Casts the stored value to the requested type.

The value may be converted into the value of the requested type if a conversion is possible. Otherwise, an exception is thrown. For example, if the field value represents a reference to a string (e.g. instance of the StrRef class), then it can be successfully converted into a number if the string referred represents a number.

Exceptions

std::runtime_error if conversion is impossible.

Definition at line 79 of file Field.h.

◆ operator bool()

operator bool ( ) const

inlineexplicitnoexcept

Tells whether the field has an associated (non-null) value.

Definition at line 41 of file Field.h.

◆ operator std::string()

operator std::string ( ) const

inlineexplicit

Returns: a string presentation.

Definition at line 47 of file Field.h.

inline

Compares the presentation for equality with the given text reference.

Definition at line 54 of file Field.h.

◆ toBitSet()

template<class BitSet>

bool toBitSet ( BitSet & value ) const

inline

bool toChar ( Char & value ) const

inline

Tries to cast the stored value into a value of the Char type.

◆ toNumber() [2/9]

bool toNumber ( Int16 & value ) const

inline

Tries to cast the stored value into a value of the Int16 type.

Returns: false if the conversion fails.

Definition at line 135 of file Field.h.

◆ toNumber() [3/9]

bool toNumber ( Int32 & value ) const

inline

Tries to cast the stored value into a value of the Int32 type.

Returns: false if the conversion fails.

Definition at line 113 of file Field.h.

◆ toNumber() [6/9]

bool toNumber ( UInt16 & value ) const

inline

Tries to cast the stored value into a value of the UInt16 type.

Returns: false if the conversion fails.

Definition at line 146 of file Field.h.
