Methods in this pseudo-class can be executed on booling-point values.

|
bool | intp () |
| Returns True because boolean values can be converted to integers (False = 0, True = 1)
|
|
bool | strp () |
| Returns True because boolean values can be converted to strings (False = "0" , True = "1" )
|
|
bool | typeCode () |
| Returns Qore::NT_BOOLEAN.
|
|
bool | val () |
| Returns itself.
|
|
bool | callp () |
| Returns False; this method is reimplemented in other types and will return True if the given expression is a callable value (ie closures or call references)
|
|
bool | empty () |
| Returns True; this method will be reimplemented in container types where it may return False.
|
|
bool | intp () |
| Returns False; this method is reimplemented in other types and will return True if the given expression can be converted to an integer.
|
|
AbstractIterator | iterator () |
| Returns an iterator object for the value; the default iterator object returned is SingleValueIterator.
|
|
int | lsize () |
| Returns 1; the return value of this method should give the list size of the value, which is normally 1 for non-lists (except for NOTHING where the size will be 0) and the number of the elements in the list for lists; this method will be reimplemented in other types where it may return other values.
|
|
int | size () |
| Returns zero; this method will be reimplemented in container types where it may return a non-zero value.
|
|
bool | strp () |
| Returns False; this method is reimplemented in other types and will return True if the given expression can be converted to a string.
|
|
bool | toBool () |
| Returns the boolean representation of the value; the default is False.
|
|
float | toFloat () |
| Returns the floating-point representation of the value; the default is 0.0.
|
|
int | toInt () |
| Returns the integer representation of the value; the default is 0.
|
|
string | toString () |
| Returns the string representation of the value; the default is an empty string.
|
|
string | type () |
| Returns the string type for the value.
|
|
int | typeCode () |
| Returns the type code for the value.
|
|
bool | val () |
| Returns False; this method is reimplemented in other types and will return True if the given expression has a value.
