## 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

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

Reimplemented from AbstractQoreNode.

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

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

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

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

Implements AbstractQoreNode.

virtual DLLEXPORT AbstractQoreNode* QoreBigIntNode::realCopy | ( |  | ) | const
