Detailed Description

this class implements Qore's 64-bit integer data type, reference-counted, dynamically-allocated only

Constructor & Destructor Documentation

DLLEXPORT QoreBigIntNode::QoreBigIntNode ( int64 v )

creates a new integer with the value of "v"

Parameters

v	the value of the integer

Member Function Documentation

virtual DLLEXPORT int QoreBigIntNode::getAsString	(	QoreString &	str,
		int	foff,
		ExceptionSink *	xsink
	)		const

virtual

concatenates the value of the integer to an existing QoreString

used for n and N printf formatting. This implementation of the function never throws a Qore-language exception

Parameters

str	the string representation of the type will be concatenated to this QoreString reference
foff	for multi-line formatting offset, -1 = no line breaks
xsink	is ignored

Returns: always returns 0

Implements AbstractQoreNode.

virtual DLLEXPORT QoreString* QoreBigIntNode::getAsString	(	bool &	del,
		int	foff,
		ExceptionSink *	xsink
	)		const

virtual

returns a QoreString representing the integer

used for n and N printf formatting

Parameters

del	if this is true when the function returns, then the returned QoreString pointer should be deleted, if false, then it must not be
foff	for multi-line formatting offset, -1 = no line breaks
xsink	is ignored NOTE: Use the QoreNodeAsStringHelper class (defined in QoreStringNode.h) instead of using this function directly

See also: QoreNodeAsStringHelper

Implements AbstractQoreNode.

virtual DLLEXPORT DateTime* QoreBigIntNode::getDateTimeRepresentation ( bool & del ) const

virtual

returns the DateTime representation of this integer (interpreted as an offset in seconds from January 1, 1970)

NOTE: Use the DateTimeValueHelper class instead of using this function directly

Parameters

del	output parameter: if del is true, then the returned DateTime pointer belongs to the caller (and must be deleted manually), if false, then it must not be

See also: DateTimeValueHelper

Reimplemented from AbstractQoreNode.

virtual DLLEXPORT void QoreBigIntNode::getDateTimeRepresentation ( DateTime & dt ) const

virtual

assigns the date representation of this integer (interpreted as an offset in seconds from January 1, 1970) to the DateTime reference passed

Parameters

dt	the DateTime reference to be assigned

Reimplemented from AbstractQoreNode.

virtual DLLEXPORT QoreString* QoreBigIntNode::getStringRepresentation ( bool & del ) const

virtual

returns a string representing the integer and sets del to true

NOTE: do not call this function directly, use QoreStringValueHelper instead

Parameters

del	output parameter: always sets del to false

See also: QoreStringValueHelper

Reimplemented from AbstractQoreNode.

virtual DLLEXPORT void QoreBigIntNode::getStringRepresentation ( QoreString & str ) const

virtual

concatentates the string representation of the integer to an existing QoreString reference

Parameters

str	a reference to a QoreString where the value of the type will be concatenated

Reimplemented from AbstractQoreNode.

virtual DLLEXPORT bool QoreBigIntNode::is_equal_hard	(	const AbstractQoreNode *	v,
		ExceptionSink *	xsink
	)		const

virtual

tests for equality without the possibility of type conversion (hard compare)

this implementation of the function does not throw any Qore-language exceptions

Parameters

v	the value to compare
xsink	is ignored in this version of the function

Implements AbstractQoreNode.

virtual DLLEXPORT bool QoreBigIntNode::is_equal_soft	(	const AbstractQoreNode *	v,
		ExceptionSink *	xsink
	)		const

virtual

tests for equality with the possibility of type conversion (soft compare)

this implementation of the function does not throw any Qore-language exceptions

Parameters

v	the value to compare
xsink	is ignored in this version of the function

Implements AbstractQoreNode.

virtual DLLEXPORT AbstractQoreNode* QoreBigIntNode::realCopy ( ) const

virtual

returns a copy of the object; the caller owns the reference count

Returns: a copy of the object; the caller owns the reference count

Implements AbstractQoreNode.
