                           int... lines)

Description copied from interface: EmbedRubyRuntimeAdapter

Parses a script and return an object which can be run(). This allows the script to be parsed once and evaluated many times.

Specified by:

parse in interface EmbedRubyRuntimeAdapter

Parameters:

script - is a Ruby script to be parsed

lines - are linenumbers to display for parse errors and backtraces. This field is optional. Only the first argument is used for parsing. When no line number is specified, 0 is applied to.

Returns:

an object which can be run

parse

public EmbedEvalUnit parse(java.io.Reader reader,
                           java.lang.String filename,
                           int... lines)

Description copied from interface: EmbedRubyRuntimeAdapter

Parses a script given by a reader and return an object which can be run(). This allows the script to be parsed once and evaluated many times.

Specified by:

parse in interface EmbedRubyRuntimeAdapter

Parameters:

reader - is used to read a script from

filename - is used as in information, for example, appears in a stack trace of an exception

lines - are linenumbers to display for parse errors and backtraces. This field is optional. Only the first argument is used for parsing. When no line number is specified, 0 is applied to.

Returns:

an object which can be run
