TorqueGenGroovy
public TorqueGenGroovy(GroovyOutlet outlet, ControllerState controllerState)
Constructs a generator interface within the given controllerState.- Parameters:
outlet
- the outlet in which this generator interface will be used, not null.controllerState
- the controller context.- Throws:
NullPointerException
- if outlet or controllerState are null.
-

Method Detail
-
mergepoint
public String mergepoint(String mergepointName) throws GeneratorException
Processes the mergepoint with the given name.- Parameters:
mergepointName
- the name of the mergepoint.- Returns:
- the output generated by the mergepoint.
- Throws:
GeneratorException
- if the mergepoint could not be processed completely.
-
getControllerState
public ControllerState getControllerState()
Returns the current controller state.- Returns:
- The current controller state, never null.
-
getModel
public Object getModel()
Returns the current model. This method is shorthand forgetControllerState().getModel()
- Returns:
- the current source element, never null.
-
option
public Object option(String key)
Returns the option with the given key. The key can either be a name prefixed with a namespace, or a name without namespace, in which case the namespace of the currently active outlet is used. In the case that the option is not set in this namespace, the parent namespaces are searched recursively. If the option is not set in any of the parent namespaces, null is returned.- Parameters:
key
- the key for the option to retrieve.- Returns:
- the option for the given key.
-
getOption
public Object getOption(String key)
Returns the option with the given key. The key can either be a name prefixed with a namespace, or a name without namespace, in which case the namespace of the currently active outlet is used. In the case that the option is not set in this namespace, the parent namespaces are searched recursively. If the option is not set in any of the parent namespaces, null is returned.- Parameters:
key
- the key for the option to retrieve.- Returns:
- the option for the given key.
-
booleanOption
public boolean booleanOption(String key)
Returns the option with the given key as boolean value. The key can either be a name prefixed with a namespace, or a name without namespace, in which case the namespace of the currently active outlet is used. In the case that the option is not set in this namespace, the parent namespaces are searched recursively. If the option is not set in any of the parent namespaces, false is returned.- Parameters:
key
- the key for the option to retrieve.- Returns:
- the option for the given key, converted to a boolean
-
intOption
public int intOption(String key)
Returns the option with the given key as int value. The key can either be a name prefixed with a namespace, or a name without namespace, in which case the namespace of the currently active outlet is used. In the case that the option is not set in this namespace, the parent namespaces are searched recursively. If the option is not set in any of the parent namespaces or empty, 0 is returned.- Parameters:
key
- the key for the option to retrieve.- Returns:
- the option for the given key, converted to a boolean
-
getVariable
public Object getVariable(String key)
Returns the variable with the given key. The key can either be a name prefixed with a namespace, or a name without namespace, in which case the namespace of the currently active outlet is used. In the case that the variable is not set in this namespace, the parent namespaces are searched recursively. If the variable is not set in any of the parent namespaces, null is returned.- Parameters:
key
- the key for the variable to retrieve.- Returns:
- the variable for the given key, or null if the variable is not set or explicitly set to null.
-
setVariable
public void setVariable(String key, Object value)
Sets a variable. The key can be given with or without namespace; in the latter case, the variable is set in the namespace of the currently active outlet. The Scope of the variable is this outlet and its children.- Parameters:
key
- the name of the variable, not nullvalue
- the value of the variable, may be null.- Throws:
NullPointerException
- if key or scope is null.IllegalArgumentException
- if the key is no valid QualifiedName.
-
setVariable
public void setVariable(String key, Object value, String scope)
Sets a variable. The key can be given with or without namespace; in the latter case, the variable is set in the namespace of the currently active outlet.- Parameters:
key
- the name of the variable, not null.value
- the value of the variable, may be null.scope
- the scope of the variable, not null.- Throws:
NullPointerException
- if key or scope is null.IllegalArgumentException
- if the key is no valid QualifiedName.
-
getSourceFile
public File getSourceFile()
Returns the currently processed source file.- Returns:
- the source file which is currently processed.
-
now
public Date now()
Returns the current date.- Returns:
- the current date, not null.
-
getCounter
public static int getCounter()
Returns a counter value which is increased each time this function is accessed. Start value is 1. IfresetCounter
is not called, the returned value is unique over the generation process.- Returns:
- the counter value.
-
resetCounter
public static void resetCounter()
Resets the counter accessible thoughgetCounter()
back to 1.
