Uses of VariableUpdater in adams.flow.source

Classes in adams.flow.source that implement VariableUpdater

Modifier and Type	Class	Description
class	StorageForLoop	Emulates the following for-loop: - positive step size: for (int i = lower; i <= upper; i += step) - negative step size: for (int i = upper; i >= lower; i += step) In each iteration, the specified variable gets updated with the current value of the for-loop variable.

Uses of VariableUpdater in adams.flow.transformer

Classes in adams.flow.transformer that implement VariableUpdater

Modifier and Type	Class	Description
class	DeleteVariable	Removes a variable by name or the variables that match the regular expression.
class	IncVariable	Increments the value of a variable by either an integer or double increment. If the variable has not been set yet, it will get set to 0. If the variable contains a non-numerical value, no increment will be performed. It is also possible to directly output the updated variable (while discarding the input token).
class	SetManyVariables	Sets the values of the variables whenever a token passes through, but does not use the token's value. Optionally, the specified values can be expanded, in case it is made up of variables itself.

class	SetVariable	Sets the value of a variable.
class	SwapVariables	Swaps the values of the two variables around, whenever a token passes through.
