Method Detail

cloneForEval

public Binding cloneForEval()

Clone the binding, but maintain a reference to the original "eval binding" to continue sharing eval context.

Returns:

a new Binding with shared eval context

clone

public Binding clone()

Clone the binding. The frame will be duplicated, and eval context will point to the new binding, but other fields will be copied as-is.

Overrides:

clone in class Object

Returns:

a new cloned Binding

getVisibility

public Visibility getVisibility()

setVisibility

public void setVisibility(Visibility visibility)

getSelf

public IRubyObject getSelf()

setSelf

public void setSelf(IRubyObject self)

getDynamicScope

public DynamicScope getDynamicScope()

Gets the dynamicVariables that are local to this block. Parent dynamic scopes are also accessible via the current dynamic scope.

Returns:

Returns all relevent variable scoping information

getDummyScope

public DynamicScope getDummyScope(StaticScope staticScope)

getFrame

public Frame getFrame()

Gets the frame.

Returns:

Returns a RubyFrame

getKlass

public RubyModule getKlass()

Gets the klass.

Returns:

Returns a RubyModule

getBacktrace

public BacktraceElement getBacktrace()

getFile

public String getFile()

setFile

public void setFile(String file)

getLine

public int getLine()

setLine

public void setLine(int line)

getMethod

public String getMethod()

setMethod

public void setMethod(String method)

equals

public boolean equals(Object other)

Overrides:

equals in class Object

getEvalScope

public final DynamicScope getEvalScope(Ruby runtime)
