Constructor & Destructor Documentation

◆ FloatRecordAttribute() [1/4]

glo::FloatRecordAttribute::FloatRecordAttribute ( )

protected

The standard constructor is not available.

◆ ~FloatRecordAttribute()

virtual glo::FloatRecordAttribute::~FloatRecordAttribute ( )

protectedvirtual

The destructor is not available. The object may only be removed from memory using forget().

◆ FloatRecordAttribute() [2/4]

glo::FloatRecordAttribute::FloatRecordAttribute	(	ClassInfoAttribute *	pType,
		const std::streampos &	rFilePos )

Constructor with parameter passing.

Parameters

[in]	pType	A class information attribute is expected.
[in]	rFilePos	The file position.

Exceptions

eut::ErrorNException An exception will be thrown if an error occurs.

Attention: Since objects of these classes are only instantiated by internal objects like Record and TableReaderInterface, and they know what they are doing, a type check of the class information attribute is omitted!

◆ FloatRecordAttribute() [3/4]

glo::FloatRecordAttribute::FloatRecordAttribute	(	ClassInfoAttribute *	pType,
		float	fValue,
		const std::streampos &	rFilePos )

Constructor with parameter passing.

Parameters

[in]	pType	A class information attribute is expected.
[in]	fValue	The value of the attribute.
[in]	rFilePos	The file position.

Exceptions

eut::ErrorNException An exception will be thrown if an error occurs.

Attention: Since objects of these classes are only instantiated by internal objects like Record and TableReaderInterface, and they know what they are doing, a type check of the class information attribute is omitted!

◆ FloatRecordAttribute() [4/4]

glo::FloatRecordAttribute::FloatRecordAttribute ( const FloatRecordAttribute & rT )

protected

Copy constructor.

Parameters

[in] rT The data is copied from this object.

See also: getCopy()

Member Function Documentation

◆ dataIsFieldContent()

virtual bool glo::FloatRecordAttribute::dataIsFieldContent ( ) const

virtual

Returns true, because the attribute data is stored as field content.

Returns: see above

Implements glo::BaseRecordAttribute.

◆ getAcceptedDecimals()

int glo::FloatRecordAttribute::getAcceptedDecimals ( ) const

Returns the number of the specified decimal places.

Returns: See above.

◆ getCopy()

virtual BaseRecordAttribute * glo::FloatRecordAttribute::getCopy ( )

virtual

Returns a copy of the object. Sometimes a copy of an attribute is needed, e.g. if a deep-copied record (with copied attributes) is needed.

Returns: The copy of this attribute

Attention: The supplied object must be removed from memory by the calling instance.

Implements glo::BaseRecordAttribute.

◆ getDataFieldLength()

virtual unsigned short glo::FloatRecordAttribute::getDataFieldLength ( ) const

virtual

Returns the record field length of the attribute value.

Returns: The field length.

See also: FLOAT_TEXT_LENGTH

Implements glo::BaseRecordAttribute.

◆ getValueAsDataString()

virtual std::string glo::FloatRecordAttribute::getValueAsDataString ( ) const

virtual

Returns the value as a formatted data string with the correct length with the correct length for the entry in the table file.
If decimal places are defined in the class information attribute, these are taken into account (e.g. the number 123 with 4 decimal places => " 123.0000", otherwise the number is delivered in "scientific-mode" (e.g. the number 123 => " 1.230000e+002").

Returns: The value as formatted data string in the correct length.

Implements glo::BaseRecordAttribute.

◆ getValueAsDisplayString()

virtual std::string glo::FloatRecordAttribute::getValueAsDisplayString ( ) const

virtual

Returns the value as it can be displayed for the GUI.

Returns: The value for the display, usually like getValueAsString()

Implements glo::BaseRecordAttribute.

◆ getValueAsStreamString()

virtual std::string glo::FloatRecordAttribute::getValueAsStreamString ( ) const

virtual

Returns the value as string for the DataStreamer.

Returns: The value for the DataStreamer.

Implements glo::BaseRecordAttribute.

◆ getValueAsString()

virtual std::string glo::FloatRecordAttribute::getValueAsString ( ) const

virtual

Returns the value of the attribute as a string. If decimal places are defined in the class information attribute, these are taken into account (e.g. the number 123 with 4 decimal places => "123.0000", otherwise the number is delivered in "scientific-mode" (e.g. the number 123 => "1.230000e+002").

Returns: The value as string.

Implements glo::BaseRecordAttribute.

◆ getValueAsVoidPointer()

virtual void * glo::FloatRecordAttribute::getValueAsVoidPointer ( )

virtual

Returns a raw pointer to the value.

Returns: The raw pointer to the value.

Implements glo::BaseRecordAttribute.

◆ getValueRef()

const float & glo::FloatRecordAttribute::getValueRef ( ) const

Returns the reference to the value.

Returns: The value.

◆ initNew()

virtual void glo::FloatRecordAttribute::initNew ( )

virtual

Reinitializes the attribute, the value is set to 0.

Implements glo::BaseRecordAttribute.

◆ operator!=()

bool glo::FloatRecordAttribute::operator!= ( const FloatRecordAttribute & rT ) const

Comparison operator.

Parameters

[in] rT The object to be compared with this one.

◆ operator=()

FloatRecordAttribute & glo::FloatRecordAttribute::operator= ( const FloatRecordAttribute & )

private

The assignment operator is not available.

◆ operator==()

bool glo::FloatRecordAttribute::operator== ( const FloatRecordAttribute & rT ) const

Comparison operator.

Parameters

[in] rT The object to be compared with this one.

◆ setValue()

void glo::FloatRecordAttribute::setValue ( float fValue )

Sets the value of the attribute.

Parameters

[in] fValue The new value.

◆ setValueFromVoid()

virtual void glo::FloatRecordAttribute::setValueFromVoid ( void * pValue )

virtual

Sets the value of the attribute. Is assigned via a static_cast.

Parameters

[in] pValue The raw pointer to the value.

Implements glo::BaseRecordAttribute.

◆ takeValue()

virtual int glo::FloatRecordAttribute::takeValue ( const BaseRecordAttribute & rT )

virtual

Adopts the value from transferred attribute, if possible. An attempt is made to cast the value in some way.

Parameters

[in] rT The persistent attribute from which the values are to be taken.

Returns: An error or warning message from subclasses will be delivered if the cast does not work.

Reimplemented from glo::BaseRecordAttribute.

Member Data Documentation

◆ m_fValue

float glo::FloatRecordAttribute::m_fValue

private
