Public Member Functions | |
DLLEXPORT | QoreFloatNode (double n_f) |
creates a new floating-point value and assigns the initial value to it | |
DLLEXPORT | QoreFloatNode () |
creates a new floating-point value and assigns 0.0 to it | |
virtual DLLEXPORT QoreString * | getStringRepresentation (bool &del) const |
returns the floating-point value converted to a string and sets del to true | |
virtual DLLEXPORT void | getStringRepresentation (QoreString &str) const |
concatentates the floating-point value to an existing QoreString reference, default implementation does nothing | |

Protected Member Functions | |
virtual DLLEXPORT | ~QoreFloatNode () |
the destructor is protected because it should not be called directly |
Qore's floating-point value type, dynamically-allocated only, reference counted.
virtual DLLEXPORT QoreFloatNode::~QoreFloatNode | ( | ) | [protected, virtual] |
the destructor is protected because it should not be called directly
DLLEXPORT QoreFloatNode::QoreFloatNode | ( | double | n_f | ) |
creates a new floating-point value and assigns the initial value to it
n_f | the value for the object |
virtual DLLEXPORT QoreString* QoreFloatNode::getAsString | ( | bool & | del, | |
int | foff, | |||
class ExceptionSink * | xsink | |||
) | const [virtual] |
returns a QoreString giving the string representation of the floating-point value, sets del to true
Used for n and N printf formatting. Do not call this function directly; use the QoreNodeAsStringHelper class (defined in QoreStringNode.h) instead
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, ignored by this implementation of the function | |
xsink | ignored by this implementation of the function |
Implements AbstractQoreNode.
virtual DLLEXPORT int QoreFloatNode::getAsString | ( | QoreString & | str, | |
int | foff, | |||
class ExceptionSink * | xsink | |||
) | const [virtual] |
concatenate the string representation of the floating-point value to an existing QoreString
used for n and N printf formatting
str | the string representation of the type will be concatenated to this QoreString reference | |
foff | for multi-line formatting offset, ignored by this implementation of the function | |
xsink | ignored by this implementation of the function |
Implements AbstractQoreNode.
virtual DLLEXPORT void QoreFloatNode::getDateTimeRepresentation | ( | DateTime & | dt | ) | const [virtual] |
assigns the date representation of the value to the DateTime reference passed
The DateTime representation is calculated by converting the floating-point value to an integer interpreted as the number of seconds offset from January 1, 1970.
dt | the DateTime reference to be assigned |
Reimplemented from AbstractQoreNode.
virtual DLLEXPORT class DateTime* QoreFloatNode::getDateTimeRepresentation | ( | bool & | del | ) | const [virtual] |
returns the DateTime representation of this value and sets del to true
The DateTime representation is calculated by converting the floating-point value to an integer interpreted as the number of seconds offset from January 1, 1970.
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 |
Reimplemented from AbstractQoreNode.
static DLLLOCAL const char* QoreFloatNode::getStaticTypeName | ( | ) | [inline, static] |
returns the type name as a c string
virtual DLLEXPORT void QoreFloatNode::getStringRepresentation | ( | QoreString & | str | ) | const [virtual] |
concatentates the floating-point value to an existing QoreString reference, default implementation does nothing
str | a reference to a QoreString where the value of the type will be concatenated |
Reimplemented from AbstractQoreNode.
virtual DLLEXPORT QoreString* QoreFloatNode::getStringRepresentation | ( | bool & | del | ) | const [virtual] |
returns the floating-point value converted to a string and sets del to true
NOTE: do not use this function directly, use QoreStringValueHelper instead
del | output parameter: del is set to true, meaning that the resulting QoreString pointer belongs to the caller (and must be deleted manually) |
Reimplemented from AbstractQoreNode.
virtual DLLEXPORT const char* QoreFloatNode::getTypeName | ( | ) | const [virtual] |
returns the type name as a c string
Implements AbstractQoreNode.
virtual DLLEXPORT bool QoreFloatNode::is_equal_hard | ( | const AbstractQoreNode * | v, | |
ExceptionSink * | xsink | |||
) | const [virtual] |
tests for equality without type conversions (hard compare)
v | the value to compare | |
xsink | ignored by this implementation of the function |
virtual DLLEXPORT bool QoreFloatNode::is_equal_soft | ( | const AbstractQoreNode * | v, | |
ExceptionSink * | xsink | |||
) | const [virtual] |
tests for equality with possible type conversion (soft compare)
v | the value to compare | |
xsink | ignored by this implementation of the function |
virtual DLLEXPORT class AbstractQoreNode* QoreFloatNode::realCopy | ( | ) | const [virtual] |
returns a copy of the object; the caller owns the reference count
