Detailed Description

template<typename T>
class vrs::DataPieceStringMap< T >

DataPiece map container, with string keys and values of type T.

Read values are extracted from the DataLayout's buffer, (VRS records reading/decoding). Staged values are stored in the map<string, T> member of this class (VRS record creation).

Constructor & Destructor Documentation

◆ DataPieceStringMap() [1/2]

template<typename T >

vrs::DataPieceStringMap< T >::DataPieceStringMap ( const string & label )

inlineexplicit

Parameters

label Name for the DataPiece.

◆ DataPieceStringMap() [2/2]

template<typename T >

vrs::DataPieceStringMap< T >::DataPieceStringMap ( const MakerBundle & bundle )

explicit

Parameters

bundle Bundle to reconstruct a DataPieceStringMap from disk.

Member Function Documentation

◆ clone()

template<typename T >

unique_ptr< DataPiece > vrs::DataPieceStringMap< T >::clone ( ) const

inlineoverridevirtual

Clone data piece.

Returns: A clone of the data piece, with the same label and same type. All the other data piece properties (default and staged values) are not cloned.

Implements vrs::DataPiece.

◆ collectVariableData()

template<typename T >

size_t vrs::DataPieceStringMap< T >::collectVariableData	(	int8_t *	data,
		size_t	bufferSize
	)

overridevirtual

Copy the staged map to the location given.

Parameters

data	Pointer where to write the staged values.
bufferSize	Max number of bytes to write.

Returns: Number of bytes written.

Implements vrs::DataPiece.

◆ get()

template<typename T >

bool vrs::DataPieceStringMap< T >::get ( map< string, T > & outValues ) const

Get read values or default values in a map.

Parameters

outValues Reference to a map<string, T> for the read or default values.

Returns: True if outValues was set from read values (maybe mapped), not default values.

◆ getDefault()

template<typename T >

const map< string, T > & vrs::DataPieceStringMap< T >::getDefault ( ) const

inline

Get the default value.

Returns: Default values. The vector might be empty if there are no defaults set.

◆ getElementTypeName()

template<typename T >

const string & vrs::DataPieceStringMap< T >::getElementTypeName ( ) const

inlineoverridevirtual

Get the name of the element type <T>.

Implements vrs::DataPiece.

◆ getVariableSize()

template<typename T >

size_t vrs::DataPieceStringMap< T >::getVariableSize ( ) const

overridevirtual

Get the size of the staged map, if any.

Returns: Number of bytes to store the staged map.

Implements vrs::DataPiece.

◆ isAvailable()

template<typename T >

bool vrs::DataPieceStringMap< T >::isAvailable ( ) const

inlineoverridevirtual

Tell if the DataPiece is available, directly or mapped successfully.

Returns: True if values can be read without using default values.

Implements vrs::DataPiece.

◆ isSame()

template<typename T >

bool vrs::DataPieceStringMap< T >::isSame ( const DataPiece * rhs ) const

overridevirtual

Compare two DataPiece objects for their equivalence. Note: the values are not compared, all the other properties are (type, name, tags, etc).

Parameters

rhs	Other DataPiece to compare to.

Returns: True if the DataPiece objects are considered the same.

Reimplemented from vrs::DataPiece.

◆ print()

template<typename T >

void vrs::DataPieceStringMap< T >::print	(	ostream &	out,
		const string &	indent
	)		const

overridevirtual

Print the DataPiece to the out stream, with many details, using indent text at the start of each line of output.

Parameters

out	Output stream to print to.
indent	Text to insert at the beginning of each output line, for indentation purposes.

Implements vrs::DataPiece.

◆ printCompact() [1/2]

void vrs::DataPieceStringMap< string >::printCompact	(	ostream &	out,
		const string &	indent
	)		const

virtual

Print the DataPiece to the out stream in compact form, using indent text at the start of each line of output.

Parameters

out	Output stream to print to.
indent	Text to insert at the beginning of each output line, for indentation purposes.

Implements vrs::DataPiece.

◆ printCompact() [2/2]

template<typename T >

void vrs::DataPieceStringMap< T >::printCompact	(	ostream &	out,
		const string &	indent
	)		const

overridevirtual

Print the DataPiece to the out stream in compact form, using indent text at the start of each line of output.

Parameters

out	Output stream to print to.
indent	Text to insert at the beginning of each output line, for indentation purposes.

Implements vrs::DataPiece.

◆ serialize()

template<typename T >

void vrs::DataPieceStringMap< T >::serialize	(	JsonWrapper &	jsonWrapper,
		const JsonFormatProfileSpec &	profile
	)

overridevirtual

Export the DataPiece as json, using a specific profile.

Parameters

jsonWrapper	Wrapper around a json type (to isolate any 3rd party library dependency).
profile	Profile describing what information needs to be exported as json.

Reimplemented from vrs::DataPiece.

◆ setDefault() [1/2]

template<typename T >

void vrs::DataPieceStringMap< T >::setDefault ( const map< string, T > & values )

inline

Set default values using a vector.

Parameters

values Vector of values to use a default.

◆ setDefault() [2/2]

template<typename T >

void vrs::DataPieceStringMap< T >::setDefault ( map< string, T > && values )

inline

Set default values using a vector.

Parameters

values Vector of values to use a default.

◆ stage() [1/2]

template<typename T >

void vrs::DataPieceStringMap< T >::stage ( const map< string, T > & values )

inline

Stage values you wish to write to disk. Does not modify the read values!

Parameters

values Values to stage, to include them in the next record created.

◆ stage() [2/2]

template<typename T >

void vrs::DataPieceStringMap< T >::stage ( map< string, T > && values )

inline

Stage values you wish to write to disk. Does not modify the read values!

◆ stageCurrentValue()

template<typename T >

bool vrs::DataPieceStringMap< T >::stageCurrentValue ( )

inlineoverridevirtual

Take the current value of the field, and stage it for writing during record creation.

Returns: True if the value is available and was staged.

Reimplemented from vrs::DataPiece.

◆ stagedValues() [1/2]

template<typename T >

map< string, T > & vrs::DataPieceStringMap< T >::stagedValues ( )

◆ stagedValues() [2/2]

template<typename T >

const map< string, T > & vrs::DataPieceStringMap< T >::stagedValues ( ) const

inline

Read-only access to the map of values you wish to write to disk.
