Constructor & Destructor Documentation

◆ VariantAdaptors() [1/2]

sptk::VariantAdaptors::VariantAdaptors ( const VariantAdaptors & other )

default

Copy constructor.

Parameters

other The other object

◆ VariantAdaptors() [2/2]

sptk::VariantAdaptors::VariantAdaptors ( VariantAdaptors && other )

defaultnoexcept

Move constructor.

Parameters

other The other object

Member Function Documentation

◆ asBool()

bool sptk::VariantAdaptors::asBool ( ) const

Conversion to bool

Converts variant string value with first char one of 'Y','y','T','t' to true, and one of 'N','n','F','f' to false. For the integer and float values, the value <=0 is false, and > 0 is true.

◆ asDate()

DateTime sptk::VariantAdaptors::asDate ( ) const

Conversion method

Converts variant value to DateTime. The time part of CDdatetime is empty.

◆ asDateTime()

DateTime sptk::VariantAdaptors::asDateTime ( ) const

Conversion method

Converts variant value to DateTime.

◆ asFloat()

double sptk::VariantAdaptors::asFloat ( ) const

Conversion to double

Converts variant value to double.

◆ asImagePtr()

const uint8_t * sptk::VariantAdaptors::asImagePtr ( ) const

Conversion method

Simply returns the internal data pointer for string/text/blob types. For incompatible types throws an exception.

◆ asInt64()

int64_t sptk::VariantAdaptors::asInt64 ( ) const

Conversion method

Converts variant value to double.

◆ asInteger()

int sptk::VariantAdaptors::asInteger ( ) const

Conversion method

Converts variant value to double.

◆ asString()

virtual String sptk::VariantAdaptors::asString ( ) const

virtual

Conversion to string

Converts variant value to string.

Reimplemented in sptk::Field.

Referenced by sptk::CFileDialog::fileName().

◆ setBool()

virtual void sptk::VariantAdaptors::setBool ( bool value )

virtual

Assignment method

◆ setBuffer()

virtual void sptk::VariantAdaptors::setBuffer	(	const uint8_t *	value,
		size_t	valueSize,
		VariantDataType	type = `VariantDataType::VAR_BUFFER`
	)

virtual

Assignment method

◆ setData()

void sptk::VariantAdaptors::setData ( const BaseVariant & other )

protected

Copies data from another CVariant

◆ setDateTime()

virtual void sptk::VariantAdaptors::setDateTime	(	DateTime	value,
		bool	dateOnly = `false`
	)

virtual

Assignment method

◆ setExternalBuffer()

virtual void sptk::VariantAdaptors::setExternalBuffer	(	uint8_t *	value,
		size_t	valueSize,
		VariantDataType	type = `VariantDataType::VAR_BUFFER`
	)

virtual

Assignment method

◆ setFloat()

virtual void sptk::VariantAdaptors::setFloat ( double value )

virtual

Assignment method

◆ setImageNdx()

virtual void sptk::VariantAdaptors::setImageNdx ( uint32_t value )

virtual

Assignment method

◆ setImagePtr()

virtual void sptk::VariantAdaptors::setImagePtr ( const uint8_t * value )

virtual

Assignment method

◆ setInt64()

virtual void sptk::VariantAdaptors::setInt64 ( int64_t value )

virtual

Assignment method

◆ setInteger()

virtual void sptk::VariantAdaptors::setInteger ( int32_t value )

virtual

Assignment method

◆ setMoney() [1/2]

virtual void sptk::VariantAdaptors::setMoney ( const MoneyData & value )

virtual

Assignment method

◆ setMoney() [2/2]

virtual void sptk::VariantAdaptors::setMoney	(	int64_t	value,
		unsigned	scale
	)

virtual

Assignment method

◆ setNull()

virtual void sptk::VariantAdaptors::setNull ( VariantDataType vtype = VariantDataType::VAR_NONE )

virtual

Sets the NULL state

Useful for the database operations. Releases the memory allocated for string/text/blob types. Sets the data to zero(s).

Parameters

vtype Optional variant type to enforce
