Method Details

tryJit

public static <T extends AbstractIRMethod & Compilable>
void tryJit(ThreadContext context,
 T self)

setCallCount

public final void setCallCount(int callCount)

getIRScope

public IRScope getIRScope()

getStaticScope

public StaticScope getStaticScope()

getArgumentDescriptors

public ArgumentDescriptor[] getArgumentDescriptors()

Description copied from interface: IRMethodArgs

Get the array of ArgumentDescriptors that represent the arguments to this method.

Specified by:

getArgumentDescriptors in interface IRMethodArgs

ensureInstrsReady

public InterpreterContext ensureInstrsReady()

retrieveInterpreterContext

private InterpreterContext retrieveInterpreterContext()

printMethodIR

protected abstract void printMethodIR()

getSignature

public Signature getSignature()

Description copied from class: DynamicMethod

Retrieve the signature of this method.

Specified by:

getSignature in interface IRMethodArgs

Overrides:

getSignature in class DynamicMethod

Returns:

the signature

getArity

@Deprecated
public Arity getArity()

Deprecated.

Description copied from class: DynamicMethod

Retrieve the arity of this method, used for reporting arity to Ruby code. This arity may or may not reflect the actual specific or variable arities of the referenced method.

Overrides:

getArity in class DynamicMethod

Returns:

The arity of the method, as reported to Ruby consumers.

dup

public DynamicMethod dup()

Description copied from class: DynamicMethod

Duplicate this method, returning DynamicMethod referencing the same code and with the same attributes. It is not required that this method produce a new object if the semantics of the DynamicMethod subtype do not require such.

Specified by:

dup in class DynamicMethod

Returns:

An identical DynamicMethod object to the target.

clone

public Object clone()

Overrides:

clone in class Object

getFile

public String getFile()

Description copied from interface: PositionAware

Get the filename for the method.

Specified by:

getFile in interface PositionAware

Returns:

the filename for the method

getLine

public int getLine()

Description copied from interface: PositionAware

Get the line number for the method. 0-based (ie. line 1 returns a 0)

Specified by:

getLine in interface PositionAware

Returns:

the line number for the method

getMethodData

public MethodData getMethodData()

Additional metadata about this method.

Overrides:

getMethodData in class DynamicMethod

getInstanceVariableNames

public Collection<String> getInstanceVariableNames()

Overrides:

getInstanceVariableNames in class DynamicMethod

toString

public String toString()

Overrides:

toString in class Object

needsToFindImplementer

public boolean needsToFindImplementer()

startSplitSuperCall

public abstract SplitSuperState startSplitSuperCall(ThreadContext context,
 IRubyObject self,
 RubyModule klazz,
 String name,
 IRubyObject[] args,
 Block block)

Calls a split method (java constructor-invoked initialize) and returns the paused state. If this method doesn't have a super call, returns null without execution.

finishSplitCall

public abstract void finishSplitCall(SplitSuperState state)
