Public Member Methods | |
| bool | complexType () |
| returns True if the list has a Hash With Declared Value Type, False if not | |
| bool | contains (auto arg) |
| Returns True if the list contains arg, False if it does not. | |
| bool | empty () |
| Returns True if the list is empty (size = 0), False if not. | |
| auto | first () |
| Returns the first entry in the list. | |
| AbstractIterator | iterator () |
| Returns a ListIterator object for the list. | |
| string | join (string str) |
| Creates a string from the list and a separator string given as an argument. | |
| auto | last () |
| Returns the last entry in the list. | |
| int | lsize () |
| Returns the number of elements in the list. | |
| AbstractIterator | rangeIterator (auto val) |
| Returns a RangeIterator object for the list elements. | |
| int | size () |
| Returns the number of elements in the list. | |
| bool | sizep () |
| Returns True since lists can return a non-zero size. | |
| int | typeCode () |

| bool | val () |
| Returns False if the list is empty (size = 0), True if not. | |
 Public Member Methods inherited from <value> | |
| 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 | complexType () |
| returns True if the value has a complex type, False if not | |
| bool | empty () |
| Returns True; this method will be reimplemented in container types where it may return False. | |
| string | fullType (__7_ bool with_namespaces) |
| returns the full type name which differs from the simple type name in case of complex types and objects | |
| 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 | sizep () |
| Returns True if the type can return a non-zero size (True for containers including binary objects and strings, False for everything else) | |
| 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. | |
| number | toNumber () |
| Returns the arbitrary-precision numeric representation of the value; the default is 0. | |
| string | toString (__7_ string encoding) |
| 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 non-empty value. | |
Methods in this pseudo-class can be executed on lists.
| bool <list>::complexType | ( | ) |
returns True if the list has a Hash With Declared Value Type, False if not
Returns True if the list contains arg, False if it does not.
This call uses "soft" comparisons (where types may be converted). The computational complexity is O(n) (n = the length of the list).
| arg | any value to check its presence in the list |
| bool <list>::empty | ( | ) |
| auto <list>::first | ( | ) |
Returns the first entry in the list.
| AbstractIterator <list>::iterator | ( | ) |
Returns a ListIterator object for the list.
Creates a string from the list and a separator string given as an argument.
Each element in the list will be converted to a string if necessary to be concatenated to the return value string; additionally if any string argument has a different character encoding than str, then it will be converted to str's character encoding before concatentation to the return value string
| str | the separator string |
| ENCODING-CONVERSION-ERROR | this exception could be thrown if the string arguments have different character encodings and an error occurs during encoding conversion |
| auto <list>::last | ( | ) |
Returns the last entry in the list.
| int <list>::lsize | ( | ) |
| AbstractIterator <list>::rangeIterator | ( | auto | val | ) |
Returns a RangeIterator object for the list elements.
| val | an optional value to be returned instead of the default integer value |
| int <list>::size | ( | ) |
Returns the number of elements in the list.
| bool <list>::sizep | ( | ) |
Returns True since lists can return a non-zero size.
| int <list>::typeCode | ( | ) |
Returns Qore::NT_LIST.
| bool <list>::val | ( | ) |
Returns False if the list is empty (size = 0), True if not.
The opposite of <list>::empty()
