public NullJavaCompiler()

方法详细信息

init

public void init(JspCompilationContext ctxt,
                 ErrorDispatcher errDispatcher,
                 boolean suppressLogging)

Initializations

release

public void release()

Release resouces used in the current compilation

setExtdirs

public void setExtdirs(String exts)

setTargetVM

public void setTargetVM(String targetVM)

setSourceVM

public void setSourceVM(String sourceVM)

setClassPath

public void setClassPath(List<File> cpath)

Java Compiler options.

saveClassFile

public void saveClassFile(String className,
                          String classFileName)

Save the generated class file to disk, if not already done.

setDebug

public void setDebug(boolean debug)

getClassLastModified

public long getClassLastModified()

Return the time the class file was generated.

getJavaWriter

public Writer getJavaWriter(String javaFileName,
                            String javaEncoding)
                     throws JasperException

Get a Writer for the Java file. The writer is used by JSP compiler. This method allows the Java compiler control where the Java file should be generated so it knows how to handle the input for java compilation accordingly.

抛出：

JasperException

compile

public JavacErrorDetail[] compile(String className,
                                  Node.Nodes pageNodes)
                           throws JasperException

Start Java compilation

参数：

className - Name of the class under compilation

抛出：

JasperException

doJavaFile

public void doJavaFile(boolean keep)

Remove/save the generated Java File from/to disk
