Method Detail

accept

public Instruction accept(NodeVisitor iVisitor)

Accept for the visitor pattern.

Overrides:

accept in class ListNode

Parameters:

iVisitor - the visitor

getOnce

public boolean getOnce()

Gets the once.

Returns:

Returns a boolean

getOptions

public int getOptions()

Gets the options.

Returns:

Returns a int

getOnceRegexp

public RubyRegexp getOnceRegexp()

For regular expressions with /o flag

Returns:

setOnceRegexp

public void setOnceRegexp(RubyRegexp regexp)

For regular expressions with /o flag, the value in here can be used for subsequent evaluations. Setting will only succeed if it is a regular expression with /o flag, and the value hasn't been already set.

Parameters:

regexp -

interpret

                             ThreadContext context,
                             IRubyObject self,
                             Block aBlock)

Overrides:
