Method Detail

run

public void run()

Specified by:

run in interface Runnable

close

public void close()

getSetters

public List<String> getSetters(Object rubyObject)

Return a list of all setters for this ruby object. A Ruby setter has the form of name= (ends with =)

Parameters:

rubyObject - the ruby object from where to get the setters

Returns:

A list of setters (method names)

require

public void require(String file)

eval

public org.jruby.RubyObject eval(String code)

callAction

public String callAction(Object rubyObject,
                String methodName)

call

public Object call(Object rubyObject,
          String methodName)

Call a method on a Ruby object. (no arguments)

Parameters:

rubyObject - The ruby object in the Java side

methodName - The name of the method to call

Returns:

Any object created and returned by the method

call

public Object call(Object rubyObject,
          String methodName,
          Class<? extends Object> returnType)

Call a method on a Ruby object. (no arguments but forcing the return type)

Parameters:

rubyObject - The ruby object in the Java side

methodName - The name of the method to call

returnType - The return type for the return value of the method

Returns:

Any object created and returned by the method

call

public Object call(Object rubyObject,
          String methodName,
          Object... params)

Call a method on a Ruby object passing some arguments to the ruby side.

Parameters:

rubyObject - The ruby object in the Java side

methodName - The name of the method to call

params - The arguments to pass to the method

Returns:

Any object created and returned by the method

call

public Object call(Object rubyObject,
          String methodName,
          Class<? extends Object> returnType,
          Object... params)

Call a method on a Ruby object passing some arguments to the ruby side. (force the return type)

Parameters:

rubyObject - The ruby object in the Java side

methodName - The name of the method to call

returnType - The return type for the return value of the method

params - The arguments to pass to the method

Returns:

Any object created and returned by the method

set

public Object set(Object rubyObject,
         String propName,
         Object value)

Call a setter for this property. It just appends '=' to construct the method name to use for the setter. Ex: set(rubyObject, "name", "hi") is equivalent to call(rubyObject, "name=", "hi")

Parameters:

rubyObject - The ruby object in the Java side

propName - The name of the property to set

value - The value of the property

Returns:

Any object created and returned by the method

respondTo

public boolean respondTo(Object rubyObject,
                String methodName)

Call Ruby's respond_to? to find out if the Ruby object responds to a method.

Parameters:

rubyObject - The ruby object in the Java side

methodName - The method name

Returns:

true if the ruby object responds to that method

isInitialized

public static boolean isInitialized()

getInstance

public static JRubyInterpreter getInstance()

loadFileFromClasspath

public void loadFileFromClasspath(String filename)
                           throws IOException

Throws:

IOException
