A database is a file that stores ;TI"Rkey-value pairs. Gdbm allows the user to store, retrieve, and delete data by ;TI"Okey. It furthermore allows a non-sorted traversal of all key-value pairs. ;TI"HA gdbm database thus provides the same functionality as a hash. As ;TI"Pwith objects of the Hash class, elements can be accessed with <tt>[]</tt>. ;TI"QFurthermore, GDBM mixes in the Enumerable module, thus providing convenient ;TI"0methods such as #find, #collect, #map, etc.;T@o; ;[ I"PA process is allowed to open several different databases at the same time. ;TI"QA process can open a database as a "reader" or a "writer". Whereas a reader ;TI"Phas only read-access to the database, a writer has read- and write-access. ;TI"RA database can be accessed either by any number of readers or by exactly one ;TI" writer at the same time.;T@S; ; i; I" Examples;T@o:RDoc::Markup::List: @type: NUMBER: @items[o:RDoc::Markup::ListItem: @label0;[o; ;[I"COpening/creating a database, and filling it with some entries:;T@o:RDoc::Markup::Verbatim;[ I"require 'gdbm' ;TI" ;TI"&gdbm = GDBM.new("fruitstore.db") ;TI" gdbm["ananas"] = "3" ;TI" gdbm["banana"] = "8" ;TI" gdbm["cranberry"] = "4909" ;TI"gdbm.close ;T: @format0o;;0;[ o; ;[I" Reading out a database:;T@o;;[ I"require 'gdbm' ;TI" ;TI"&gdbm = GDBM.new("fruitstore.db") ;TI"$gdbm.each_pair do |key, value| ;TI"" print "#{key}: #{value}\n" ;TI" end ;TI"gdbm.close ;T;0o; ;[I" produces;T@o;;[I"banana: 8 ;TI"ananas: 3 ;TI"cranberry: 4909 ;T;0S; ; i; I" Links;T@o;;: BULLET;[o;;0;[o; ;[I"&http://www.gnu.org/software/gdbm/;T: @fileI"ext/gdbm/gdbm.c;T:0@omit_headings_from_table_of_contents_below0;0;0[ [ U:RDoc::Constant[i I" READER;TI"GDBM::READER;T00o;;[o; ;[I" open database as a reader;T@;@W;0@W@cRDoc::NormalClass0U;[i I" WRITER;TI"GDBM::WRITER;T00o;;[o; ;[I" open database as a writer;T@;@W;0@W@@c0U;[i I" WRCREAT;TI"GDBM::WRCREAT;T00o;;[o; ;[I"Popen database as a writer; if the database does not exist, create a new one;T@;@W;0@W@@c0U;[i I" NEWDB;TI"GDBM::NEWDB;T00o;;[o; ;[I"Aopen database as a writer; overwrite any existing databases ;T@;@W;0@W@@c0U;[i I" FAST;TI"GDBM::FAST;T00o;;[o; ;[I"Cflag for #new and #open. this flag is obsolete for gdbm >= 1.8;T@;@W;0@W@@c0U;[i I" SYNC;TI"GDBM::SYNC;T00o;;[o; ;[I"2flag for #new and #open. only for gdbm >= 1.8;T@;@W;0@W@@c0U;[i I" NOLOCK;TI"GDBM::NOLOCK;T00o;;[o; ;[I" flag for #new and #open;T@;@W;0@W@@c0U;[i I" VERSION;TI"GDBM::VERSION;T00o;;[o; ;[I" version of the gdbm library;T@;@W;0@W@@c0[[I"Enumerable;To;;[ ;@W;0I"ext/gdbm/gdbm.c;T[[I" class;T[[: public[[I"new;T@�[I" open;T@�[:protected[ [: private[ [I" instance;T[[;[-[I"[];T@�[I"[]=;T@�[I"cachesize=;T@�[I" clear;T@�[I" close;T@�[I" closed?;T@�[I" delete;T@�[I"delete_if;T@�[I" each;T@�[I" each_key;T@�[I"each_pair;T@�[I"each_value;T@�[I" empty?;T@�[I"fastmode=;T@�[I" fetch;T@�[I" has_key?;T@�[I"has_value?;T@�[I" include?;T@�[I" invert;T@�[I"key;T@�[I" key?;T@�[I" keys;T@�[I" length;T@�[I" member?;T@�[I" reject;T@�[I" reject!;T@�[I"reorganize;T@�[I" replace;T@�[I" select;T@�[I" shift;T@�[I" size;T@�[I" store;T@�[I" sync;T@�[I"syncmode=;T@�[I" to_a;T@�[I" to_hash;T@�[I" update;T@�[I" value?;T@�[I" values;T@�[I"values_at;T@�[;[ [; [ [ [U:RDoc::Context::Section[i 0o;;[ ;0;0[@W@WcRDoc::TopLevel
