Method Detail

base_getLength

public ATNumber base_getLength()
                        throws InterpreterException

Throws:

InterpreterException

base_at

public ATObject base_at(ATNumber index)
                 throws InterpreterException

Throws:

InterpreterException

base_atPut

public ATObject base_atPut(ATNumber index,
                           ATObject value)
                    throws InterpreterException

Throws:

InterpreterException

base_isEmpty

public ATBoolean base_isEmpty()
                       throws InterpreterException

Throws:

InterpreterException

base_each_

public ATNil base_each_(ATClosure clo)
                 throws InterpreterException

Apply a closure to each element of the table. [ tab ].each: { |v| ... }

Returns:

nil, always

Throws:

InterpreterException

base_map_

public ATTable base_map_(ATClosure clo)
                  throws InterpreterException

Map a closure over each element of the table, resulting in a new table. result := [ tab ].map: { |v| ... }

Throws:

InterpreterException

base_with_collect_

public ATObject base_with_collect_(ATObject init,
                                   ATClosure clo)
                            throws InterpreterException

Collect all elements of the table by combining them using the given closure. The first time closure is called, the initialization element is passed as first argument. result := [ tab ].with: 0 collect: { |total, next| total + next }

Throws:

InterpreterException

base_filter_

public ATTable base_filter_(ATClosure clo)
                     throws InterpreterException

Throws:

InterpreterException

base_find_

public ATObject base_find_(ATClosure clo)
                    throws InterpreterException

Return the index of the first element for which the given predicate returns true. Returns nil if no element satisfying the closure can be found. result := [ tabl ].find: { |elt| booleanCondition(elt) }

Throws:
