Method Details

call

public Object call(Object object,
 String method,
 Object[] args)
            throws BSFException

Description copied from interface: BSFEngine

This is used by an application to call into the scripting engine to make a function/method call. The "object" argument is the object whose method is to be called, if that applies. For non-OO languages, this is typically ignored and should be given as null. For pretend-OO languages such as VB, this would be the (String) name of the object. The arguments are given in the args array.

Parameters:

object - object on which to make the call

method - name of the method / procedure to call

args - the arguments to be given to the procedure

Throws:

BSFException - if anything goes wrong while eval'ing a BSFException is thrown. The reason indicates the problem.

eval

public Object eval(String source,
 int lineNo,
 int columnNo,
 Object expr)
            throws BSFException

Description copied from interface: BSFEngine

This is used by an application to evaluate an expression. The expression may be string or some other type, depending on the language. (For example, for BML it'll be an org.w3c.dom.Element object.)

Parameters:

source - (context info) the source of this expression (e.g., filename)

lineNo - (context info) the line number in source for expr

columnNo - (context info) the column number in source for expr

expr - the expression to evaluate

Throws:

BSFException - if anything goes wrong while eval'ing a BSFException is thrown. The reason indicates the problem.

iexec

public void iexec(String source,
 int lineNo,
 int columnNo,
 Object script)
           throws BSFException

Description copied from class: BSFEngineImpl

Default impl of interactive execution - calls eval and ignores the result.

Specified by:

iexec in interface BSFEngine

Overrides:

iexec in class BSFEngineImpl

Parameters:

source - (context info) the source of this expression (e.g., filename)

lineNo - (context info) the line number in source for expr

columnNo - (context info) the column number in source for expr

script - the script to execute

Throws:

BSFException - if anything goes wrong while exec'ing a BSFException is thrown. The reason indicates the problem.

exec

public void exec(String source,
 int lineNo,
 int columnNo,
 Object script)
          throws BSFException

Description copied from class: BSFEngineImpl

Default impl of execute - calls eval and ignores the result.

Specified by:

exec in interface BSFEngine

Overrides:

exec in class BSFEngineImpl

Parameters:

source - (context info) the source of this expression (e.g., filename)

lineNo - (context info) the line number in source for expr

columnNo - (context info) the column number in source for expr

script - the script to execute

Throws:

BSFException - if anything goes wrong while exec'ing a BSFException is thrown. The reason indicates the problem.

terminate

public void terminate()

Description copied from interface: BSFEngine

Graceful termination

Specified by:

terminate in interface BSFEngine

Overrides:

terminate in class BSFEngineImpl
