  • Method Details

    • initFromContext

      public void initFromContext(Context cx)

    • getErrorReporter

      public final ErrorReporter getErrorReporter()

    • setErrorReporter

      public void setErrorReporter(ErrorReporter errorReporter)

    • getLanguageVersion

      public final int getLanguageVersion()

    • setLanguageVersion

      public void setLanguageVersion(int languageVersion)

    • isGenerateDebugInfo

      public final boolean isGenerateDebugInfo()

    • setGenerateDebugInfo

      public void setGenerateDebugInfo(boolean flag)

    • isReservedKeywordAsIdentifier

      public final boolean isReservedKeywordAsIdentifier()

    • setReservedKeywordAsIdentifier

      public void setReservedKeywordAsIdentifier(boolean flag)

    • isAllowMemberExprAsFunctionName

      public final boolean isAllowMemberExprAsFunctionName()
      Extension to ECMA: if 'function <name>' is not followed by '(', assume <name> starts a memberExpr

    • setAllowMemberExprAsFunctionName

      public void setAllowMemberExprAsFunctionName(boolean flag)

    • isXmlAvailable

      public final boolean isXmlAvailable()

    • setXmlAvailable

      public void setXmlAvailable(boolean flag)

    • getOptimizationLevel

      public final int getOptimizationLevel()

    • setOptimizationLevel

      public void setOptimizationLevel(int level)

    • isGeneratingSource

      public final boolean isGeneratingSource()

    • getWarnTrailingComma

      public boolean getWarnTrailingComma()

    • setWarnTrailingComma

      public void setWarnTrailingComma(boolean warn)

    • isStrictMode

      public final boolean isStrictMode()

    • setStrictMode

      public void setStrictMode(boolean strict)

    • reportWarningAsError

      public final boolean reportWarningAsError()

    • setGeneratingSource

      public void setGeneratingSource(boolean generatingSource)
      Specify whether or not source information should be generated.

      Without source information, evaluating the "toString" method on JavaScript functions produces only "[native code]" for the body of the function. Note that code generated without source is not fully ECMA conformant.

    • isGenerateObserverCount

      public boolean isGenerateObserverCount()
      Returns:
      true iff code will be generated with callbacks to enable instruction thresholds

    • setGenerateObserverCount

      public void setGenerateObserverCount(boolean generateObserverCount)
      Turn on or off generation of code with callbacks to track the count of executed instructions. Currently only affects JVM byte code generation: this slows down the generated code, but code generated without the callbacks will not be counted toward instruction thresholds. Rhino's interpretive mode does instruction counting without inserting callbacks, so there is no requirement to compile code differently.
      Parameters:
      generateObserverCount - if true, generated code will contain calls to accumulate an estimate of the instructions executed.

    • isRecordingComments

      public boolean isRecordingComments()

    • setRecordingComments

      public void setRecordingComments(boolean record)

    • isRecordingLocalJsDocComments

      public boolean isRecordingLocalJsDocComments()

    • setRecordingLocalJsDocComments

      public void setRecordingLocalJsDocComments(boolean record)

    • setRecoverFromErrors

      public void setRecoverFromErrors(boolean recover)
      Turn on or off full error recovery. In this mode, parse errors do not throw an exception, and the parser attempts to build a full syntax tree from the input. Useful for IDEs and other frontends.

    • recoverFromErrors

      public boolean recoverFromErrors()

    • setIdeMode

      public void setIdeMode(boolean ide)
      Puts the parser in "IDE" mode. This enables some slightly more expensive computations, such as figuring out helpful error bounds.

    • isIdeMode

      public boolean isIdeMode()

    • getActivationNames

      public Set<String> getActivationNames()

    • setActivationNames

      public void setActivationNames(Set<String> activationNames)

    • setAllowSharpComments

      public void setAllowSharpComments(boolean allow)
      Mozilla sources use the C preprocessor.

    • getAllowSharpComments

      public boolean getAllowSharpComments()

    • ideEnvirons

      public static CompilerEnvirons ideEnvirons()
      Returns a CompilerEnvirons suitable for using Rhino in an IDE environment. Most features are enabled by default. The ErrorReporter is set to an ErrorCollector.
