Method Detail

public Object evaluate(String expression)

A helper method to allow the dynamic evaluation of groovy expressions using this scripts binding as the variable scope

Parameters:: expression - is the Groovy script expression to evaluate

public Object evaluate(File file)

A helper method to allow the dynamic evaluation of groovy expressions using this scripts binding as the variable scope

Parameters:: file - is the Groovy script to evaluate

public Binding getBinding()

public Object getProperty(String property)

public Object invokeMethod(String name, Object args)

Invoke a method (or closure in the binding) defined.

Parameters:: name - method to call; args - arguments to pass to the method

Returns:: value

public void print(Object value)

Prints the value to the current 'out' variable which should be a PrintWriter or at least have a print() method defined on it. If there is no 'out' property then print to standard out.

Parameters:: format - the format to follow; values - an array of values to be formatted

public void println()

Prints a newline to the current 'out' variable which should be a PrintWriter or at least have a println() method defined on it. If there is no 'out' property then print to standard out.

public void println(Object value)

Prints the value and a newline to the current 'out' variable which should be a PrintWriter or at least have a println() method defined on it. If there is no 'out' property then print to standard out.

public Object run()

The main instance method of a script which has variables in scope as defined by the current Binding instance.

public void run(File file, String[] arguments)

A helper method to allow scripts to be run taking command line arguments

public void setBinding(Binding binding)

public void setProperty(String property, Object newValue)
