                          java.util.List<Instr> instructions)

InterpreterContext

public InterpreterContext(IRScope scope,
                          java.util.concurrent.Callable<java.util.List<Instr>> instructions)
                   throws java.lang.Exception

Throws:

java.lang.Exception

Method Detail

getEngine

public InterpreterEngine getEngine()

getRescueIPCs

public int[] getRescueIPCs()

getRequiredArgsCount

public int getRequiredArgsCount()

getScope

public IRScope getScope()

buildComplete

public boolean buildComplete()

Is the build complete? For startup builds, which this class represents, we finish build in the constructor so it is always complete. For FullInterpreterContext this is more complicated (see javadocs there for more info).

getCFG

public CFG getCFG()

allocateTemporaryVariables

public java.lang.Object[] allocateTemporaryVariables()

allocateTemporaryBooleanVariables

public boolean[] allocateTemporaryBooleanVariables()

allocateTemporaryFixnumVariables

public long[] allocateTemporaryFixnumVariables()

allocateTemporaryFloatVariables

public double[] allocateTemporaryFloatVariables()

getStaticScope

public StaticScope getStaticScope()

getFileName

public java.lang.String getFileName()

getName

public RubySymbol getName()

getInstructions

public Instr[] getInstructions()

computeScopeFlagsFromInstructions

public void computeScopeFlagsFromInstructions()

newDynamicScope

public DynamicScope newDynamicScope(ThreadContext context)

Get a new dynamic scope. Note: This only works for method scopes (ClosureIC will throw).

hasExplicitCallProtocol

public boolean hasExplicitCallProtocol()

pushNewDynScope

public boolean pushNewDynScope()

reuseParentDynScope

public boolean reuseParentDynScope()

popDynScope

public boolean popDynScope()

receivesKeywordArguments

public boolean receivesKeywordArguments()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toStringInstrs

public java.lang.String toStringInstrs()

setEngine

public void setEngine(InterpreterEngine engine)

getFlags

public java.util.EnumSet<IRFlags> getFlags()
