Member Function Documentation

◆ autoValue()

static CorrelationId BloombergLP::bmqt::CorrelationId::autoValue ( )

static

Return a CorrelationId having a unique, automatically assigned opaque value.

◆ makeUnset()

CorrelationId & BloombergLP::bmqt::CorrelationId::makeUnset ( )

inline

◆ setNumeric()

CorrelationId & BloombergLP::bmqt::CorrelationId::setNumeric ( bsls::Types::Int64 numeric )

inline

Set the value of this object value to the specified numeric. Return a reference to this object.

◆ setPointer()

CorrelationId & BloombergLP::bmqt::CorrelationId::setPointer ( void * pointer )

inline

Set the value of this object value to the specified pointer. Return a reference to this object.

◆ setSharedPointer()

CorrelationId & BloombergLP::bmqt::CorrelationId::setSharedPointer ( const bsl::shared_ptr< void > & sharedPtr )

inline

◆ isUnset()

bool BloombergLP::bmqt::CorrelationId::isUnset ( ) const

inline

Referenced by type().

◆ isNumeric()

bool BloombergLP::bmqt::CorrelationId::isNumeric ( ) const

inline

Return true if the value of this object is an integer value, and otherwise return false.

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()(), theNumeric(), and type().

◆ isPointer()

bool BloombergLP::bmqt::CorrelationId::isPointer ( ) const

inline

Return true if the value of this object is a pointer value, and otherwise return false.

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()(), thePointer(), and type().

◆ isSharedPtr()

bool BloombergLP::bmqt::CorrelationId::isSharedPtr ( ) const

inline

Return true if the value of this object is a shared pointer value, and otherwise return false.

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()(), theSharedPtr(), and type().

◆ isAutoValue()

bool BloombergLP::bmqt::CorrelationId::isAutoValue ( ) const

inline

Return true if the value of this object is an auto correlation value, and otherwise return false.

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()(), and type().

◆ theNumeric()

bsls::Types::Int64 BloombergLP::bmqt::CorrelationId::theNumeric ( ) const

inline

Return the 64-bit integer value of this object. The behavior is undefined unless method isNumeric returns true.

References isNumeric().

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()().

◆ thePointer()

void * BloombergLP::bmqt::CorrelationId::thePointer ( ) const

inline

Return the pointer value of this object. The behavior is undefined unless method isPointer returns true.

References isPointer().

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()().

◆ theSharedPtr()

const bsl::shared_ptr< void > & BloombergLP::bmqt::CorrelationId::theSharedPtr ( ) const

References isSharedPtr().

Referenced by BloombergLP::bmqt::CorrelationIdLess::operator()().

◆ type()

CorrelationId::Type BloombergLP::bmqt::CorrelationId::type ( ) const

inline

References e_AUTO_VALUE, e_NUMERIC, e_POINTER, e_SHARED_PTR, e_UNSET, isAutoValue(), isNumeric(), isPointer(), isSharedPtr(), and isUnset().

◆ print()

bsl::ostream & BloombergLP::bmqt::CorrelationId::print	(	bsl::ostream &	stream,
		int	level = `0`,
		int	spacesPerLevel = `4`
	)		const

Format this object to the specified output stream at the (absolute value of) the optionally specified indentation level and return a reference to stream. If level is specified, optionally specify spacesPerLevel, the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative format the entire output on one line, suppressing all but the initial indentation (as governed by level). If stream is not valid on entry, this operation has no effect.
