baljsn::EncodeImplUtil_SelectionVisitor< FORMATTER > Class Template Reference

#include <baljsn_encodeimplutil.h>

Detailed Description

template<class FORMATTER>
class baljsn::EncodeImplUtil_SelectionVisitor< FORMATTER >

This component-private class provides a function object that closes over the formatter, logStream, and options parameters that are shared between all encoding operations provided in this component. The function-call operator of this class provides an overload set that accepts a "selection" object that satisfies one of the bdlat type-category concepts, and a "selection info" object that describes various metadata of the selection.

Member Typedef Documentation

◆ FormattingMode

template<class FORMATTER >
typedef int baljsn::EncodeImplUtil_SelectionVisitor< FORMATTER >::FormattingMode

FormattingMode is an alias to the type of an int-valued bdlat_FormattingMode bit-field. A FormattingMode value is not valid unless it is equal to an enumerator of bdlat_FormattingMode or a valid bitwise-or of two or more such enumerators. See the component-level documentation of bdlat_formattingmode for a description of the set of valid formatting-mode values.

Constructor & Destructor Documentation

◆ EncodeImplUtil_SelectionVisitor()

template<class FORMATTER >
baljsn::EncodeImplUtil_SelectionVisitor< FORMATTER >::EncodeImplUtil_SelectionVisitor ( FORMATTER *  formatter,
bsl::ostream *  logStream,
bool  isNextObjectFirst,
const EncoderOptions options 
)
inline

Construct an EncodeImplUtil_SelectionVisitor object having the specified formatter, logStream, isNextObjectFirst, and options attributes.

Member Function Documentation

◆ isNextObjectFirst()

template<class FORMATTER >
bool baljsn::EncodeImplUtil_SelectionVisitor< FORMATTER >::isNextObjectFirst ( ) const
inline

Return the value of the isNextObjectFirst attribute of this object.

◆ operator()()

template<class FORMATTER >
template<class TYPE , class SELECTION_INFO >
int baljsn::EncodeImplUtil_SelectionVisitor< FORMATTER >::operator() ( const TYPE &  selection,
const SELECTION_INFO &  selectionInfo 
)
inline

Encode the JSON representation of the specified selection, having the name equal to the name attribute of the specified selectionInfo to the JSON formatter attribute of this object, according to the specified formattingMode. If the isNextObjectFirst attribute of this object is true, then the representation of the selection contains no leading sequence delimiter, and does contain such a delimiter otherwise. The options attribute of this object configures aspects of the JSON representation of the selection. If this operation is not successful, load an unspecified, human-readable description of the error condition to the logStream attribute of this object. Return 0 on success, and a non-zero value otherwise.

Precondition
The behavior is undefined unless the selection satisfies both the static and dynamic requirements of the bdlat type-category concept corresponding to the specified category. See the component-level documentation of baljsn_encoderoptions for a description of the effects, if any, of each option in the options on the JSON representation of the selection. See the package-level documentation of {bdlat} for an introduction to the requirements of bdlat type-category concepts.
