table_type() = set

delete/2	Delete an entry from an ets table.
insert/2	Insert an entry into an ets table.
lookup/2	Look up an entry in an ets table.
lookup_element/3	Look up an element from an entry in an ets table.
new/2	Create a new ets table.


delete(Table::table(), Key::term()) -> true

Table: a reference to the ets table
Key: the key used to lookup one or more entries to delete

returns: true; otherwise, an error is raised if arguments are bad

Delete an entry from an ets table.


insert(Table::table(), Entry::tuple()) -> true

Table: a reference to the ets table
Entry: the entry to insert

returns: true; otherwise, an error is raised if arguments are bad

Insert an entry into an ets table.


lookup(Table::table(), Key::term()) -> [tuple()]

Table: a reference to the ets table
Key: the key used to lookup one or more entries

returns: the entry in a set, or a list of entries, if the table permits

Look up an entry in an ets table.


lookup_element(Table::table(), Key::term(), Pos::pos_integer()) -> term()

Table: a reference to the ets table
Key: the key used to lookup one or more entries
Pos: index of the element to retrieve (1-based)

returns: the Pos:nth element of entry in a set, or a list of entries, if the table permits

Look up an element from an entry in an ets table.


new(Name::atom(), Options::options()) -> table()

Name: the ets table name
Options: the options used to create the table

returns: A new ets table

Create a new ets table.
