  • Method Details

    • getBooleanOption

      boolean getBooleanOption(String option, boolean defaultValue)
      Returns the identified option as a boolean value. The specified defaultValue is returned if no such option is found or if debug is not enabled.

      Options are specified in the general form <Bundle-SymbolicName>/<option-path>. For example, org.eclipse.core.runtime/debug

      Parameters:
      option - the name of the option to lookup
      defaultValue - the value to return if no such option is found
      Returns:
      the value of the requested debug option or the defaultValue if no such option is found.
    • getOption

      String getOption(String option)
      Returns the identified option. A null value is returned if no such option is found or if debug is not enabled.

      Options are specified in the general form <Bundle-SymbolicName>/<option-path>. For example, org.eclipse.core.runtime/debug

      Parameters:
      option - the name of the option to lookup
      Returns:
      the value of the requested debug option or null
    • getOption

      String getOption(String option, String defaultValue)
      Returns the identified option. The specified defaultValue is returned if no such option is found or if debug is not enabled.

      Options are specified in the general form <Bundle-SymbolicName>/<option-path>. For example, org.eclipse.core.runtime/debug

      Parameters:
      option - the name of the option to lookup
      defaultValue - the value to return if no such option is found
      Returns:
      the value of the requested debug option or the defaultValue if no such option is found.
    • getIntegerOption

      int getIntegerOption(String option, int defaultValue)
      Returns the identified option as an int value. The specified defaultValue is returned if no such option is found or if a NumberFormatException is thrown while converting the option value to an integer or if debug is not enabled.

      Options are specified in the general form <Bundle-SymbolicName>/<option-path>. For example, org.eclipse.core.runtime/debug

      Parameters:
      option - the name of the option to lookup
      defaultValue - the value to return if no such option is found
      Returns:
      the value of the requested debug option or the defaultValue if no such option is found.
    • getOptions

      Map<String,String> getOptions()
      Returns a snapshot of the current options. All keys and values are of type String. If no options are set then an empty map is returned.

      If debug is not enabled then the snapshot of the current disabled values is returned. See setDebugEnabled(boolean).

      Returns:
      a snapshot of the current options.

      3.6
    • setOption

      void setOption(String option, String value)
      Sets the identified option to the identified value. If debug is not enabled then the specified option is not changed.
      Parameters:
      option - the name of the option to set
      value - the value of the option to set
    • setOptions

      void setOptions(Map<String,String> options)
      Sets the current option key/value pairs to the specified options. The specified map replaces all keys and values of the current debug options. An IllegalArgumentException is thrown if any key or value in the specified map is not of type String.

      If debug is not enabled then the specified options are saved as the disabled values and no notifications will be sent. See setDebugEnabled(boolean). If debug is enabled then notifications will be sent to the listeners which have options that have been changed, added or removed.

      Parameters:
      options - the new set of options
      Since:
      3.6
    • removeOption

      void removeOption(String option)
      Removes the identified option. If debug is not enabled then the specified option is not removed.
      Parameters:
      option - the name of the option to remove
      Since:
      3.5
    • isDebugEnabled

      boolean isDebugEnabled()
      Returns true if debugging/tracing is currently enabled.
      Returns:
      true if debugging/tracing is currently enabled; Otherwise false is returned.
      Since:
      3.5
    • setDebugEnabled

      void setDebugEnabled(boolean value)
      Enables or disables debugging/tracing.

      When debug is disabled all debug options are unset. When disabling debug the current debug option values are stored in memory as disabled values. If debug is re-enabled the disabled values will be set back and enabled. The disabled values are only stored in memory and if the framework is restarted then the disabled option values will be lost.

      Parameters:
      value - If true, debug is enabled, otherwise debug is disabled.

      3.5
    • setFile

      void setFile(File newFile)
      Sets the current file used to trace messages to. A null value is allowed which indicates that System.out will be used for trace messages.
      Parameters:
      newFile - The file to be used for tracing messages. A null value is allowed.
      Since:
      3.5
    • getFile

      File getFile()
      Returns the trace file if it is set, otherwise null is returned. A null value indicates that System.out is used for trace messages.
      Returns:
      the trace file if it is set, otherwise null is returned.
      Since:
      3.5
    • newDebugTrace

      DebugTrace newDebugTrace(String bundleSymbolicName)
      Creates a new DebugTrace instance for the specified bundle symbolic name. If a DebugTrace object has already been created for the specified symbolic name then the existing DebugTrace object will be returned. The class name, method name, and line number of any callers to the DebugTrace API will automatically be determined by parsing the stack trace of the executing thread. These attributes will be set based on the first caller of this API.
      Parameters:
      bundleSymbolicName - The symbolic name of the bundle that is requesting a new instance of a DebugTrace.
      Returns:
      A new or existing DebugTrace object for the specified plug-in ID
      Since:
      3.5
    • newDebugTrace

      DebugTrace newDebugTrace(String bundleSymbolicName, Class<?> traceEntryClass)
      Create a new DebugTrace instance for the specified bundle symbolic name. If a DebugTrace object has already been created for the specified symbolic name then the existing DebugTrace object will be returned. The class name, method name, and line number of any callers to the DebugTrace API will automatically be determined by parsing the stack trace of the executing thread. The values of these attributes will be based on the last invocation to the specified traceEntryClass found in the parsed stack trace.
      Parameters:
      bundleSymbolicName - The symbolic name of the bundle that is requesting a new instance of a DebugTrace.
      traceEntryClass - The class that is being used to abstract tracing calls for a bundle.
      Returns:
      A new or existing DebugTrace object for the specified plug-in ID
