A set of adaptors for types belonging to the Java language or Java SDK. Includes: - a set of functions for instantiating Java array types given a stream of values, for example, [[createJavaIntArray]], [[createJavaFloatArray]], [[createJavaByteArray]], [[createJavaBooleanArray]], [[createJavaObjectArray]], and [[createJavaStringArray]], - a set of functions for converting between Ceylon's [[Array]] class and Java array types, for example, [[javaIntArray]], [[javaFloatArray]], ...

This module allows you to read and write to streams, such as files, sockets and pipes. See the `ceylon.io` package for usage examples.

This module provides an arbitrary-precision integer numeric type. The type [[Whole|ceylon.whole::Whole]] is a first-class numeric type and support all the usual mathematical operations: Whole i = wholeNumber(12P); Whole j = wholeNumber(3); ...

This module allows you to convert between text and binary forms of data. For efficiency of I/O (see the `ceylon.io` module), [[Buffer]]s are the core representation which [[ceylon.buffer.codec::Codec]]s output from the encode/decode operations, but ...

This module defines APIs for defining HTTP endpoints and executing HTTP servers. A [[ceylon.http.server::Server]] represents a HTTP server.

Compiler

This module enables updates to multiple databases within a single transaction. It is integrated with [[module ceylon.dbc]].

This module defines a bidirectional conversion between `ceylon.ast` and the RedHat compiler AST, as well as functions that directly parse code to `ceylon.ast` nodes using the RedHat compiler. `ceylon.ast` → RedHat AST: ...

A formatter for the Ceylon programming language. # Command line usage Note: if the `ceylon format` plugin wasn’t installed by default in your distribution, you can add it by running: ~~~sh ceylon plugin install ceylon.formatter/1.3.3 ~~~ To format ...

This module offers some components for JDBC-based database connectivity. The main component is the class [[Sql]], an instance of which may be obtained for any given [[javax.sql::DataSource]].

This module provides basic cross-platform regular expression support. It's based on Google's [RegExp object](http://www.gwtproject.org/javadoc/latest/com/google/gwt/regexp/shared/RegExp.html) for GWT.
