          boolean isSmapSuppressed()

      Is the generation of SMAP info for JSR45 debugging suppressed?

    - #### isSmapDumped

          boolean isSmapDumped()

    - #### getTrimSpaces

          boolean getTrimSpaces()

      Returns:
        `true` to remove template text that consists entirely of whitespace

    - #### getIeClassId

          String getIeClassId()

      Gets the class-id value that is sent to Internet Explorer when using <jsp:plugin> tags.
      Returns:
        Class-id value

    - #### getScratchDir

          File getScratchDir()

      What is my scratch dir?

    - #### getClassPath

          String getClassPath()

      What classpath should I use while compiling the servlets generated from JSP files?

    - #### getCompiler

          String getCompiler()

      Compiler to use.

      If `null` (the default), the java compiler from Eclipse JDT project, bundled with Tomcat, will be used. Otherwise, the `javac` task from Apache Ant will be used to call an external java compiler and the value of this option will be passed to it. See Apache Ant documentation for the possible values.

    - #### getCompilerTargetVM

          String getCompilerTargetVM()

      The compiler target VM, e.g. 1.1, 1.2, 1.3, 1.4, 1.5 or 1.6.

    - #### getCompilerSourceVM

          String getCompilerSourceVM()

      The compiler source VM, e.g. 1.3, 1.4, 1.5 or 1.6.

    - #### getCompilerClassName

          String getCompilerClassName()

      Jasper Java compiler class to use.

    - #### getTldLocationsCache

          TldLocationsCache getTldLocationsCache()

      The cache for the location of the TLD's for the various tag libraries 'exposed' by the web application. A tag library is 'exposed' either explicitly in web.xml or implicitly via the uri tag in the TLD of a taglib deployed in a jar file (WEB-INF/lib).
      Returns:
        the instance of the TldLocationsCache for the web-application.

    - #### getJavaEncoding

          String getJavaEncoding()

      Java platform encoding to generate the JSP page servlet.

    - #### getFork

          boolean getFork()

      The boolean flag to tell Ant whether to fork JSP page compilations.

      Is used only when Jasper uses an external java compiler (wrapped through a `javac` Apache Ant task).

    - #### getJspConfig

          JspConfig getJspConfig()

      Obtain JSP configuration information specified in web.xml.

    - #### isXpoweredBy

          boolean isXpoweredBy()

      Is generation of X-Powered-By response header enabled/disabled?

    - #### getTagPluginManager

          TagPluginManager getTagPluginManager()

      Obtain a Tag Plugin Manager

    - #### genStringAsCharArray

          boolean genStringAsCharArray()

      Indicates whether text strings are to be generated as char arrays.
      Returns:
        `true` if text strings are to be generated as char arrays, `false` otherwise

    - #### getModificationTestInterval

          int getModificationTestInterval()

      Modification test interval.

    - #### getRecompileOnFail

          boolean getRecompileOnFail()

      Re-compile on failure.

    - #### isCaching

          boolean isCaching()

      Is caching enabled (used for precompilation).

    - #### getCache

          Map<String,TagLibraryInfo> getCache()

      The web-application wide cache for the TagLibraryInfo tag library descriptors, used if `isCaching()` returns `true`.

      Using this cache avoids the cost of repeating the parsing of a tag library descriptor XML file (performed by TagLibraryInfoImpl.parseTLD).

      Returns:
        the Map(String uri, TagLibraryInfo tld) instance.

    - #### getMaxLoadedJsps

          int getMaxLoadedJsps()

      The maximum number of loaded jsps per web-application. If there are more jsps loaded, they will be unloaded. If unset or less than 0, no jsps are unloaded.

    - #### getJspIdleTimeout

          int getJspIdleTimeout()

      The idle time in seconds after which a JSP is unloaded. If unset or less or equal than 0, no jsps are unloaded.

    - #### getQuoteAttributeEL

          boolean getQuoteAttributeEL()

      Returns:
        `true` if EL expressions used within attributes should have the quoting rules in JSP.1.6 applied to the expression.
