| class MEMBER{ETP,ATP<$CONTAINER{ETP}} |
|---|
| **** | Various membership functions on containers |
| COMPARE{_} |
| count(a: ATP,v:ETP):INT |
|---|
| **** | The number of elements that are `elt_eq' to `v'. Self may be void. |
| count_if(a: ATP,test:ROUT{ETP}:BOOL):INT |
|---|
| **** | The number of elements which satisfy `test'. Self may be void. |
| every(a: ATP,test:ROUT{ETP}:BOOL):BOOL |
|---|
| **** | True if every element of self satisfies `test'. Self may be void. |
| find_if(a: ATP,test:ROUT{ETP}:BOOL):ETP |
|---|
| **** | Use inout Return leftmost element of self which satisfies `test', or void if there is none. Self may be void. |
| notany(a: ATP,test:ROUT{ETP}:BOOL):BOOL |
|---|
| **** | True if none of the elements of self satisfies `test'. Self may be void. |
| notevery(a: ATP,test:ROUT{ETP}:BOOL):BOOL |
|---|
| **** | True if not every element of self satisfies `test'. Self may be void. |
| some(a: ATP,test:ROUT{ETP}:BOOL):BOOL |
|---|
| **** | True if some element of self satisfies `test'. Self may be void. |

| elt_eq(e1,e2:ETP):BOOL .. Included as elt_eq |
|---|
| **** | The "less than" relation used in the sorting routines. Compares the object "id" by default. May be redefined in descendants. |
| elt_hash(e:ETP):INT .. Included as elt_hash |
|---|
| **** | A hash value associated with an element. Must have the property that if "elt_eq(e1,e2)" then "elt_hash(e1)=elt_hash(e2)". Can be defined to always return 0, but many routines will then become quadratic. Uses object "id" by default. May be redefined in descendants. |
| elt_lt(e1,e2:ETP):BOOL .. Included as elt_lt |
|---|
| **** | The "less than" relation used in the sorting routines. Compares the object "id" by default. May be redefined in descendants. |
| elt_nil: ETP .. Included as elt_nil |
|---|
| **** | Return the nil value. If the element is under $NIL then return e.nil. Otherwise, return void

| is_elt_nil(e:ETP):BOOL .. Included as is_elt_nil |
