A place holder for various things that are used through out the JSP
engine. This is a per-request/per-context data structure. Some of
the instance variables are set at different points.
Most of the path-related stuff is here - mangling names, versions, dirs,
loading resources and dealing with uris.
createCompiler
public Compiler createCompiler()
throws JasperException
Create a "Compiler" object based on some init param data. This
is not done yet. Right now we're just hardcoding the actual
compilers that are created.
getClassFileName
public String getClassFileName()
getClassLoader
public ClassLoader getClassLoader()
What class loader to use for loading classes while compiling
this JSP?
getClassPath
public String getClassPath()
The classpath that is passed off to the Java compiler.
getCompiler
public Compiler getCompiler()
getContentType
public String getContentType()
Get the content type of this JSP.
Content type includes content type and encoding.
getJavaPath
public String getJavaPath()
Path of the Java file relative to the work directory.
getJspFile
public String getJspFile()
Path of the JSP URI. Note that this is not a file name. This is
the context rooted URI of the JSP file.
getOptions
public Options getOptions()
Get hold of the Options object for this context.
getOutputDir
public String getOutputDir()
The output directory to generate code into. The output directory
is make up of the scratch directory, which is provide in Options,
plus the directory derived from the package name.
getRealPath
public String getRealPath(String path)
Gets the actual path of a URI relative to the context of
the compilation.
getResource
public URL getResource(String res)
throws MalformedURLException
getResourceAsStream
public java.io.InputStream getResourceAsStream(String res)
Gets a resource as a stream, relative to the meanings of this
context's implementation.
- a null if the resource cannot be found or represented
as an InputStream.
getResourcePaths
public Set getResourcePaths(String path)
getServletClassName
public String getServletClassName()
Just the class name (does not include package name) of the
generated class.
getServletContext
public ServletContext getServletContext()
getServletJavaFileName
public String getServletJavaFileName()
Full path name of the Java file into which the servlet is being
generated.
getServletPackageName
public String getServletPackageName()
Package name for the generated class is make up of the base package
name, which is user settable, and the derived package name. The
derived package name directly mirrors the file heirachy of the JSP page.
getTagFileJarUrl
public URL getTagFileJarUrl()
Returns the JAR file in which the tag file for which this
JspCompilationContext was created is packaged, or null if this
JspCompilationContext does not correspond to a tag file, or if the
corresponding tag file is not packaged in a JAR.
getTagFileJarUrls
public Hashtable getTagFileJarUrls()
Returns the tag-file-name-to-JAR-file map of this compilation unit,
which maps tag file names to the JAR files in which the tag files are
packaged.
The map is populated when parsing the tag-file elements of the TLDs
of any imported taglibs.
getTagInfo
public TagInfo getTagInfo()
getTldLocation
public String[] getTldLocation(String uri)
throws JasperException
Gets the 'location' of the TLD associated with the given taglib 'uri'.
- An array of two Strings: The first element denotes the real
path to the TLD. If the path to the TLD points to a jar file, then the
second element denotes the name of the TLD entry in the jar file.
Returns null if the given uri is not associated with any tag library
'exposed' in the web application.
getWriter
public ServletWriter getWriter()
Where is the servlet being generated?
incrementRemoved
public void incrementRemoved()
isErrorPage
public boolean isErrorPage()
Are we processing something that has been declared as an
errorpage?
isPrototypeMode
public boolean isPrototypeMode()
True if we are compiling a tag file in prototype mode.
ie we only generate codes with class for the tag handler with empty
method bodies.
isRemoved
public boolean isRemoved()
isTagFile
public boolean isTagFile()
keepGenerated
public boolean keepGenerated()
Are we keeping generated code around?
resolveRelativeUri
public String resolveRelativeUri(String uri)
Get the full value of a URI relative to this compilations context
uses current file as the base.
setClassLoader
public void setClassLoader(URLClassLoader loader)
setClassPath
public void setClassPath(String classPath)
The classpath that is passed off to the Java compiler.
setContentType
public void setContentType(String contentType)
setErrorPage
public void setErrorPage(boolean isErrPage)
setPrototypeMode
public void setPrototypeMode(boolean pm)
setServletClassName
public void setServletClassName(String className)
setServletJavaFileName
public void setServletJavaFileName(String servletJavaFileName)
setServletPackageName
public void setServletPackageName(String servletPackageName)
The package name into which the servlet class is generated.
setTagInfo
public void setTagInfo(TagInfo tagi)
