gnu.classpath
Interface Configuration

public interface Configuration

This file defines compile-time constants that can be accessed by java code. It is pre-processed by configure.

Field Summary

static java.lang.String CLASSPATH_HOME
          The value of CLASSPATH_HOME is the location that the classpath libraries and support files where installed in.

static java.lang.String CLASSPATH_VERSION
          The release version number of GNU Classpath.

static boolean DEBUG
          The value of DEBUG is substituted according to whether the "--enable-debug" argument was passed to configure.

static java.lang.String default_awt_peer_toolkit
          Name of default AWT peer library.

static boolean HAVE_NATIVE_GENERATE_PROXY_CLASS
          Set to true if the VM provides a native method to implement the second part of Proxy.getProxyClass: conversion of an array of methods into an actual proxy class.

static boolean HAVE_NATIVE_GET_PROXY_CLASS
          Set to true if the VM provides a native method to implement Proxy.getProxyClass completely, including argument verification.

static boolean HAVE_NATIVE_GET_PROXY_DATA
          Set to true if the VM provides a native method to implement the first part of Proxy.getProxyClass: generation of the array of methods to convert, and verification of the arguments.

static boolean INIT_LOAD_LIBRARY
          The value of LOAD_LIBRARY is substituted according to whether the "--enable-load-library" or "--disable-load-library" argument was passed to configure.

static boolean JAVA_LANG_SYSTEM_EXPLICIT_INITIALIZATION
          Whether to automatically run the init* methods in java.lang.System (the default) at class initialization time or whether to have the VM explicitly invoke them.

Field Detail

CLASSPATH_HOME

public static final java.lang.String CLASSPATH_HOME

The value of CLASSPATH_HOME is the location that the classpath libraries and support files where installed in. It is set according to the argument for --prefix given to configure and used to set the System property gnu.classpath.home.

CLASSPATH_VERSION

public static final java.lang.String CLASSPATH_VERSION

The release version number of GNU Classpath. It is set according to the value of 'version' in the configure[.in] file and used to set the System property gnu.classpath.version.

See Also:: Constant Field Values

DEBUG

public static final boolean DEBUG

The value of DEBUG is substituted according to whether the "--enable-debug" argument was passed to configure. Code which is made conditional based on the value of this flag - typically code that generates debugging output - will be removed by the optimizer in a non-debug build.

INIT_LOAD_LIBRARY

public static final boolean INIT_LOAD_LIBRARY

The value of LOAD_LIBRARY is substituted according to whether the "--enable-load-library" or "--disable-load-library" argument was passed to configure. By default, configure should define this is as true. If set to false, loadLibrary() calls to load native function implementations, typically found in static initializers of classes which contain native functions, will be omitted. This is useful for runtimes which pre-link their native function implementations and do not require additional shared libraries to be loaded.

HAVE_NATIVE_GET_PROXY_CLASS

public static final boolean HAVE_NATIVE_GET_PROXY_CLASS

Set to true if the VM provides a native method to implement Proxy.getProxyClass completely, including argument verification. If this is true, HAVE_NATIVE_GET_PROXY_DATA and HAVE_NATIVE_GENERATE_PROXY_CLASS should be false.

See Also:: java.lang.reflect.Proxy, Constant Field Values

HAVE_NATIVE_GET_PROXY_DATA

public static final boolean HAVE_NATIVE_GET_PROXY_DATA

Set to true if the VM provides a native method to implement the first part of Proxy.getProxyClass: generation of the array of methods to convert, and verification of the arguments. If this is true, HAVE_NATIVE_GET_PROXY_CLASS should be false.

See Also:: java.lang.reflect.Proxy, Constant Field Values

HAVE_NATIVE_GENERATE_PROXY_CLASS

public static final boolean HAVE_NATIVE_GENERATE_PROXY_CLASS

Set to true if the VM provides a native method to implement the second part of Proxy.getProxyClass: conversion of an array of methods into an actual proxy class. If this is true, HAVE_NATIVE_GET_PROXY_CLASS should be false.

See Also:: java.lang.reflect.Proxy, Constant Field Values

default_awt_peer_toolkit

public static final java.lang.String default_awt_peer_toolkit

Name of default AWT peer library.

See Also:: Constant Field Values

JAVA_LANG_SYSTEM_EXPLICIT_INITIALIZATION

public static final boolean JAVA_LANG_SYSTEM_EXPLICIT_INITIALIZATION

Whether to automatically run the init* methods in java.lang.System (the default) at class initialization time or whether to have the VM explicitly invoke them. The default is false, meaning the VM does not explicitly run the initializers.
