Method Detail

newQuerySolutionTable

public static QuerySolutionTable newQuerySolutionTable()

allocateIterator

public AbstractIterator allocateIterator()

Overrides:

allocateIterator in class Dictionary

sort

public QuerySolutionTable sort(java.lang.reflect.Method predicate)

Perform a stable, destructive sort of self according to predicate, and return the result. If predicate has a '<' semantics, the result will be in ascending order.

Parameters:

predicate -

Returns:

QuerySolutionTable

consify

public Cons consify()

Collect all solutions of self into a cons list and return the result.

Overrides:

consify in class Stella_Object

Returns:

Cons

clear

public void clear()

nth

public QuerySolution nth(int position)

Return the nth solution in self, or NULL if it is empty.

Parameters:

position -

Returns:

QuerySolution

nonEmptyP

public boolean nonEmptyP()

Return TRUE if self has at least 1 entry.

Returns:

boolean

emptyP

public boolean emptyP()

Return TRUE if self has zero entries.

Returns:

boolean

length

public int length()

Return the number of entries in self.

Overrides:

length in class AbstractCollection

Returns:

int

pop

public QuerySolution pop()

Remove and return the first solution of self or NULL if the table is empty.

Returns:

QuerySolution

removeAt

public void removeAt(Vector key)

Remove the solution identified by key from self. To preserve the solution ordering chain, the solution is marked as deleted and will be completely removed upon the next iteration through self.

Parameters:

key -

insertAt

public void insertAt(Vector key,
                     QuerySolution value)

Insert value identified by key into self. If a solution with that key already exists, destructively modify it with the slot values of value. This is necessary to preserve the order of solutions in self.

Parameters:

key -

value -

lookup

public Stella_Object lookup(Vector key)

Lookup the solution identified by key in self and return its value, or NULL if no such solution exists.

Parameters:

key -

Returns:

Stella_Object

accessQuerySolutionTableSlotValue

public static Stella_Object accessQuerySolutionTableSlotValue(QuerySolutionTable self,
                                                              Symbol slotname,
                                                              Stella_Object value,

public Surrogate primaryType()

Description copied from class: Stella_Object

Returns the primary type of self. Gets defined automatically for every non-abstract subclass of OBJECT.

Overrides:

primaryType in class Stella_Object

Returns:

Surrogate
