getJavaWriter
in interfaceJavaCompiler
-
getClassLastModified
public long getClassLastModified()
Description copied from interface:JavaCompiler
Return the time the class file was generated.- Specified by:
getClassLastModified
in interfaceJavaCompiler
-
compile
public JavacErrorDetail[] compile(java.lang.String className, Node.Nodes pageNodes) throws JasperException
Description copied from interface:JavaCompiler
Start Java compilation- Specified by:
compile
in interfaceJavaCompiler
- Parameters:
className
- Name of the class under compilation- Throws:
JasperException
