Class GeneratedCodeClass

java.lang.Object

org.biojava.utils.bytecode.GeneratedCodeClass

All Implemented Interfaces:

CodeClass

public class GeneratedCodeClass
extends Object
implements CodeClass

A CodeClass implementation that is used to generate new classes.

When creating classes, instantiate one of these, add fields and methods. Associate CodeGenerator instances with methods. Then, use GeneratedClassLoader to make a new class.

Method Detail

setSourceFile

public void setSourceFile(String sourceFile)

Set the source file associated with this code class.

The source file appears in debugging output and stack traces. Use this method to set the source file that this generated class will clame to be from. You can use non-file names e.g. uri:myGenerator:proxy/foo

To un-set the source file, use null.

Parameters:

sourceFile - the source file for this class

getSourceFile

public String getSourceFile()

Get the source file associated with this code class.

Null indicates that no source file is set.

Returns:

the source file for this code class

setDeprecated

public void setDeprecated(boolean deprecated)

Set the deprecation flag.

If deprecated is true, the class will be flagged as deprecated.

Parameters:

deprecated - the new value of the deprecation

isDeprecated

public boolean isDeprecated()

Get the deprecation flag.

Returns:

wether or not this class is deprecated

Description copied from interface: CodeClass

Get a method by name and argument list.

Specified by:

getMethod in interface CodeClass

Parameters:

name - the name of the method

args - the arguments it takes

Returns:

a matching method

Throws:

NoSuchMethodException - if there is no maching method
