org.jruby.compiler.impl.InheritedCacheCompiler

org.jruby.compiler.impl.InvokeDynamicCacheCompiler

All Implemented Interfaces:

CacheCompiler

public class InvokeDynamicCacheCompiler
extends InheritedCacheCompiler

A CacheCompiler that uses invokedynamic as a lazy thunk for literals and other invokedynamic features like SwitchPoint to produce fast (nearly free) invalidatable caches for things like constant lookup.

Method Detail

cacheConstant

public void cacheConstant(BaseBodyCompiler method,
                 String constantName)

Cache a constant reference using invokedynamic. This cache uses a java.lang.invoke.SwitchPoint as the invalidation mechanism in order to avoid the cost of constantly pinging a constant generation in org.jruby.Ruby. This allows a nearly free constant cache.

Specified by:

cacheConstant in interface CacheCompiler

Overrides:

cacheConstant in class InheritedCacheCompiler

Parameters:

method - the method compiler with which bytecode is emitted

constantName - the name of the constant to look up

cacheConstantBoolean

public void cacheConstantBoolean(BaseBodyCompiler method,
                        String constantName)

Cache a constant boolean using invokedynamic. This cache uses a java.lang.invoke.SwitchPoint as the invalidation mechanism in order to avoid the cost of constantly pinging a constant generation in org.jruby.Ruby. This allows a nearly free constant cache.

Specified by:

cacheConstantBoolean in interface CacheCompiler

Overrides:

cacheConstantBoolean in class InheritedCacheCompiler

Parameters:

method - the method compiler with which bytecode is emitted

constantName - the name of the constant to look up

cacheByteList

public void cacheByteList(BaseBodyCompiler method,
                 org.jruby.util.ByteList contents)

This doesn't get used, since it's only used from cacheRegexp in superclass, and that is completely bound via invokedynamic now. Implemented here and in InvokeDynamicSupport for consistency.

Specified by:

cacheByteList in interface CacheCompiler

Overrides:

cacheByteList in class InheritedCacheCompiler

Parameters:

method - the method compiler with which bytecode is emitted

contents - the contents of the bytelist to cache

cacheRubyEncoding

public void cacheRubyEncoding(BaseBodyCompiler method,
                     org.jcodings.Encoding encoding)

Cache the __ENCODING__ keyword using invokedynamic.

Specified by:

cacheRubyEncoding in interface CacheCompiler

Overrides:

cacheRubyEncoding in class InheritedCacheCompiler

Parameters:

method - the method compiler with which bytecode is emitted

encoding - the encoding for this script
