Method Summary

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method and Description
`void`	`appendLine(String scriptLine)` Adds a single line of script code using auto-indentation.
`void`	`appendRaw(String script)` Adds script code appending the script code as is without using auto-indentation.
`void`	`assign(String variableName, String expression)` Variable assignment.
`void`	`assign(Variable variable, String expression)` Variable assignment.
`void`	`defineFunction(String name)`
`void`	`defineThread(String threadName)` Start a thread definition with a given thread name.
`void`	`elseCondition()` Adds an else branch.
`void`	`elseIfCondition(String expression)` Adds an else-if branch.
`void`	`end()` Insert an end.
`String`	`generateScript()` Generate a string with the full script code.
`String`	`getResolvedVariableName(Variable variable)` Returns a registered variable name that can be used in a script.
`void`	`globalVariable(String variableName, String expression)` Deprecated. Use `assign(Variable variable, String expression)` instead.
`void`	`ifCondition(String expression)` Start an if-conditional.
`void`	`ifNotCondition(String expression)` Start a negated if-conditional
`void`	`incrementVariable(Variable variable)` Add 1 to the variable value.
`void`	`returnMethod()` Return from method.
`void`	`runThread(String threadHandle, String threadName)` Start a previously defined thread.
`void`	`set_payload(double payloadMass)` Deprecated. In the script code generated by this method, the 'set_payload(m, cog)' script function will be called without specifying the optional 'cog' parameter. This means that the currently active TCP will be used as Center of Gravity (CoG) with the side effect that later calls to the 'set_tcp()' script function will also change the CoG to the new TCP. Use `set_payload(double payloadMass, double centerOfGravityX, double centerOfGravityY, double centerOfGravityZ)` instead.
`void`	`set_payload(double payloadMass, double centerOfGravityX, double centerOfGravityY, double centerOfGravityZ)` Sets the mass and Center of Gravity (CoG) of the payload.
`void`	`set_tcp(double x, double y, double z, double rx, double ry, double rz)` Set the Tool Center Point (TCP).
`void`	`set_tcp(TCP tcp)` Set the Tool Center Point (TCP).
`void`	`sleep(double seconds)` Sleep for a number of seconds.
`void`	`sync()` Uses up the remaining "physical" time a thread has in the current frame.
`void`	`whileCondition(String expression)` Starts a while-loop with a loop invariant.
`void`	`whileNot(String expression)` Starts a while-loop with a negated loop invariant.
`void`	`whileTrue()` Starts a while true loop.
`void`	`writeChildren()` Use this method when generating script code for a node that has children nodes.

  - appendLine
```
void appendLine(String scriptLine)
```
    Adds a single line of script code using auto-indentation.
    
    Parameters:
    
    scriptLine - single line of script code to append.
  - appendRaw
```
void appendRaw(String script)
```
    Adds script code appending the script code as is without using auto-indentation.
    
    Parameters:
    
    script - script code to append.
  - generateScript
```
String generateScript()
```
    Generate a string with the full script code.
    
    Returns:
    
    the resulting script as a string.
  - writeChildren
```
void writeChildren()
```
    Use this method when generating script code for a node that has children nodes.
    A simple example:
```
 
    writer.ifCondition(expression)
    writer.writeChildren()          // let children nodes generate code.
    writer.end()
 
 
```
    In most cases you probably only want to call writeChildren() once, but it is possible to call it multiple times and thus have children nodes generate their code multiple times.

String getResolvedVariableName(Variable variable)
```
    Returns a registered variable name that can be used in a script.
    
    A variable is registered if it has been stored in a DataModel instance or used for the configuration of a built-in PolyScope program node.
    Please note: The name of a variable in the script can be different from the value of Variable.getDisplayName(). You should not use the value of Variable.getDisplayName() in a script.
    
    Parameters:
    
    variable - a registered Variable. Not null.
    
    Returns:
    
    variable name that can be used in a script.
    
    Throws:
    
    IllegalArgumentException - if the variable was not registered in the data model or used for the configuration of a built-in PolyScope program node.
    
    ClassCastException - if the variable was not created by VariableFactory.
