any firstValue()
Returns the value assigned to the first key in the hash if any or NOTHING if the hash has no keys...
list values()
Returns a list of values of the hash.
list keys()
Returns a list of key names of the hash.
bool val()
Returns False if the hash has no keys, True if it does.
Methods in this pseudo-class are available to be executed on any value type (even NOTHING); this is t...

bool hasKey(softstring key)
Returns True if the key exists in the hash (may or may not be assigned a value), False if not...
HashListIterator contextIterator()
Returns a HashListIterator object for the hash.
This class an iterator class for hashes.
Definition: QC_HashPairIterator.dox.h:32
int size()
Returns the number of keys in the hash.
AbstractIterator iterator()
Returns a HashIterator object for the hash.
list list(...)
Returns a list of the arguments passed at the top level.
any lastValue()
Returns the value assigned to the last key in the hash if any or NOTHING if the hash has no keys...
HashKeyIterator keyIterator()
Returns a HashKeyIterator object for the hash.
int typeCode()
Returns Qore::NT_HASH.
*string lastKey()
Returns the last key name in the hash or NOTHING if the hash has no keys.
bool sizep()
Returns True since hashes can return a non-zero size.
*string firstKey()
Returns the first key name in the hash or NOTHING if the hash has no keys.
This class an iterator class for hashes of lists as returned by Qore::SQL::Datasource::select() and Q...

bool empty()
Returns True if the hash has no keys, False if it does.
HashPairIterator pairIterator()
Returns a HashPairIterator object for the hash.
bool compareKeys(hash oh)
Returns True if the hash argument passed has the same keys in the same order as the current hash...
Methods in this pseudo-class can be executed on hash values.
Definition: Pseudo_QC_Hash.dox.h:5
bool hasKeyValue(softstring key)
Returns True if the key exists and is assigned to a value, False if not.
hash hash(object obj)
Returns a hash of an object&#39;s members.
This class an iterator class for hashes.
