Detailed Description

Exposes operations to access value and make a compatible conversion.

Definition at line 32 of file Field.h.

Constructor & Destructor Documentation

Field() [1/3]

Field ( const ValueConverter & converter )

inlineprotected

Initializes the field.

Definition at line 39 of file Field.h.

Field() [2/3]

Field ( )

inline

Initializes the field with no value.

Definition at line 59 of file Field.h.

Field() [3/3]

Field ( const Field & other )

inline

Initializes as the copy of the other field.

Definition at line 66 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.

Definition at line 88 of file Field.h.

operator bool()

operator bool ( ) const

inline

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

Definition at line 74 of file Field.h.

operator=()

Field & operator= ( const Field & other )

inline

Re-initializes the field as a copy of the other one.

Definition at line 244 of file Field.h.

toStr() [1/2]

std::string toStr ( ) const

inline

Returns the text representation.

Definition at line 228 of file Field.h.

toStr() [2/2]

void toStr ( std::string & str ) const

inline

Outputs the text representation into the given string.

Definition at line 238 of file Field.h.

tryCast() [1/14]

template<class BitSet>

bool tryCast ( BitSet & value, typename BitSet::Bits * = nullptr ) const

inline

Tries to cast the stored value into a value of the type representing a BitSet.

Returned value indicates whether the casting succeeded.

Definition at line 213 of file Field.h.

tryCast() [2/14]

bool tryCast ( Char & value ) const

inline

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

Returned value indicates whether the casting succeeded.

Definition at line 106 of file Field.h.

tryCast() [3/14]

bool tryCast ( Int16 & value ) const

inline

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

Returned value indicates whether the casting succeeded.

Definition at line 130 of file Field.h.

tryCast() [4/14]

bool tryCast ( Int32 & value ) const

inline

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

Returned value indicates whether the casting succeeded.

Definition at line 146 of file Field.h.

tryCast() [5/14]

bool tryCast ( Int64 & value ) const

inline

Tries to cast the stored value into a value of the Int64 type.

Returned value indicates whether the casting succeeded.

Definition at line 162 of file Field.h.

tryCast() [6/14]

bool tryCast ( Int8 & value ) const

inline

Tries to cast the stored value into a value of the Int8 type.

Returned value indicates whether the casting succeeded.

Definition at line 114 of file Field.h.

tryCast() [7/14]

bool tryCast ( MaturityMonthYear & value ) const

inline

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

Returned value indicates whether the casting succeeded.

Definition at line 186 of file Field.h.

tryCast() [8/14]

bool tryCast ( StrRef & str ) const

inline

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

Returned value indicates whether the casting succeeded.

Definition at line 98 of file Field.h.

tryCast() [9/14]

bool tryCast ( Timestamp & value ) const

inline

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

Returned value indicates whether the casting succeeded.

Definition at line 178 of file Field.h.

tryCast() [10/14]

template<class Enumeration>

bool tryCast ( typename Enumeration::Enum & value ) const

inline

Tries to cast the stored value into a value of the given Enumeration type.

Returned value indicates whether the casting succeeded.

Definition at line 195 of file Field.h.

tryCast() [11/14]

bool tryCast ( UInt16 & value ) const

inline
