Constructor Description

TextProgressIndicator(java.io.PrintStream out, boolean profile)
Constructs a new indicator which will output to a given stream.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`endStage()`	Indicates that no more `ProgressIndicator.setLevel(double)` calls will be made until the next `ProgressIndicator.startStage(java.lang.String)`.
`void`	`logMessage(java.lang.String msg)`	Registers a comment about the progress of the algorithm.
`void`	`setLevel(double level)`	Specifies that the work of the most recently-started stage is a certain proportion complete.
`void`	`startStage(java.lang.String stage)`	Indicates that a number of `ProgressIndicator.setLevel(double)` calls may follow, followed by a `ProgressIndicator.endStage()` call.

public TextProgressIndicator(java.io.PrintStream out,
                             boolean profile)
```
    Constructs a new indicator which will output to a given stream.
    
    Parameters:
    
    out - output stream
    
    profile - true iff profiling reports are to be made along with the normal progress log

  - startStage
```
public void startStage(java.lang.String stage)
```
    Description copied from interface: ProgressIndicator
    
    Indicates that a number of ProgressIndicator.setLevel(double) calls may follow, followed by a ProgressIndicator.endStage() call.
    
    Specified by:
    
    startStage in interface ProgressIndicator
    
    Parameters:
    
    stage - name/description of the processing stage
  - setLevel
```
public void setLevel(double level)
```
    Description copied from interface: ProgressIndicator
    
    Specifies that the work of the most recently-started stage is a certain proportion complete. Calls to this method must take place between paired calls to ProgressIndicator.startStage(java.lang.String) and ProgressIndicator.endStage(), preferably with non-decreasing values of level.
    The method may throw an InterruptedException as a message to the caller that the work should be interrupted. A caller which receives such an exception should stop using resources and tidy up as soon as is convenient.
    
    Specified by:
    
    setLevel in interface ProgressIndicator
    
    Parameters:
    
    level - value between 0. and 1. indicating amount of completion
  - endStage
```
public void endStage()
```
    Description copied from interface: ProgressIndicator
    
    Indicates that no more ProgressIndicator.setLevel(double) calls will be made until the next ProgressIndicator.startStage(java.lang.String).
    
    Specified by:
    
    endStage in interface ProgressIndicator
  - logMessage
```
public void logMessage(java.lang.String msg)
```
    Description copied from interface: ProgressIndicator
    
    Registers a comment about the progress of the algorithm. This should not be called between calls to ProgressIndicator.startStage(java.lang.String) and ProgressIndicator.endStage().
    
    Specified by:
    
    logMessage in interface ProgressIndicator
    
    Parameters:
    
    msg - message
