Uses of InputConsumer in adams.flow.control

Classes in adams.flow.control that implement InputConsumer

Modifier and Type	Class	Description
class	AbstractContainerUpdater	Ancestor for control actors that update a specific value of a container using the defined sub-actors.
class	AbstractDataContainerFileChecker<T extends DataContainer>	Abstract ancestor for transformers that check data container files whether they are consistents before passing on the file/file arrays.
class	AbstractTee	Abstract ancestor for actors that tee-off tokens.
class	ArrayGenerate	Applies all sub-actors to the input token and generates an array from the collected output. Each of the branches is expected to produce at most one output token (ideally one per branch, otherwise there will be null elements in the output array).
class	ArrayProcess	Applies all sub-actors to each of the array elements.
class	Block	Blocks the propagation of tokens if the condition evaluates to 'true', therefore acts like the 'continue' control statement. In case of integer or double tokens that arrive at the input, these can be accessed in the expression via 'X'. The following grammar is used for evaluating the boolean expressions (depends on the selected condition): expr_list ::= '=' expr_list expr_part | expr_part ; expr_part ::= expr ; expr ::= ( expr ) # data types | number | string | boolean | date # constants | true | false | pi | e | now() | today() # negating numeric value | -expr # comparisons | expr < expr | expr <= expr | expr > expr | expr >= expr | expr = expr | expr != expr (or: expr <> expr) # boolean operations | ! expr (or: not expr) | expr & expr (or: expr and expr) | expr | expr (or: expr or expr) | if[else] ( expr , expr (if true) , expr (if false) ) | ifmissing ( variable , expr (default value if variable is missing) ) # arithmetics | expr + expr | expr - expr | expr * expr | expr / expr | expr ^ expr (power of) | expr % expr (modulo) ; # numeric functions | abs ( expr ) | sqrt ( expr ) | log ( expr ) | exp ( expr ) | sin ( expr ) | cos ( expr ) | tan ( expr ) | rint ( expr ) | floor ( expr ) | pow[er] ( expr , expr ) | ceil ( expr ) | year ( expr ) | month ( expr ) | day ( expr ) | hour ( expr ) | minute ( expr ) | second ( expr ) | weekday ( expr ) | weeknum ( expr ) # string functions | substr ( expr , start [, end] ) | left ( expr , len ) | mid ( expr , start , len ) | right ( expr , len ) | rept ( expr , count ) | concatenate ( expr1 , expr2 [, expr3-5] ) | lower[case] ( expr ) | upper[case] ( expr ) | trim ( expr ) | matches ( expr , regexp ) | trim ( expr ) | len[gth] ( str ) | find ( search , expr [, pos] ) | replace ( str , pos , len , newstr ) | substitute ( str , find , replace [, occurrences] ) ; Notes: - Variables are either all upper case letters (e.g., "ABC") or any character apart from "]" enclosed by "[" and "]" (e.g., "[Hello World]"). - 'start' and 'end' for function 'substr' are indices that start at 1. - Index 'end' for function 'substr' is excluded (like Java's 'String.substring(int,int)' method) - Line comments start with '#' - Semi-colons (';') or commas (',') can be used as separator in the formulas, e.g., 'pow(2,2)' is equivalent to 'pow(2;2)' - dates have to be of format 'yyyy-MM-dd' or 'yyyy-MM-dd HH:mm:ss' - times have to be of format 'HH:mm:ss' or 'yyyy-MM-dd HH:mm:ss' - the characters in square brackets in function names are optional: e.g.
class	Branch	Branches off the flow into several sub-branches, each being supplied with a copy of the same object being passed into this meta-actor.
class	Breakpoint	Allows to pause the execution of the flow when this actor is reached and the condition evaluates to 'true'.
class	CallableActorScreenshot	Takes a screenshot of a callable actor whenever a token passes through. The screenshot can either be written to disk (and the input token is forwarded), or the screenshot is forwarded as adams.data.image.BufferedImageContainer (dropping the input token).

Of course, this actor should only be used during development for debugging purposes as can slow down the execution significantly depending on how expensive the view generation is.
class	JDeps	Runs jdeps on the classname arriving at the input. The application's classpath is automatically added to the command-line if no classpath directories or jars are provided. Classpath directories and jars get combined, but directories take precedence over jars.
class	JMap	Runs jmap whenever a token gets passed through.
class	LaunchTee	Launches the sub-flow in a separate thread each time a token arrives. Internally, a adams.flow.control.LocalScopeTee is used to manage the scope and forward the token.

class	LocalScopeTee	Executes the sub-actors whenever a token gets passed through, just like the adams.flow.control.Tee actor, but also provides its own scope for variables and internal storage. It is possible to 'propagate' or 'leak' variables and storage items from within the local scope back to the output scope.
class	LocalScopeTransformer	Provides a local scope for the sub-actors. It is possible to 'propagate' or 'leak' variables and storage items from within the local scope back to the output scope.

It is possible to 'propagate' or 'leak' variables and storage items from within the local scope back to the output scope.
class	Once	Tees off a token only once to its sub-actors. However, this can be reset when the monitored variable changes.
class	PlotContainerUpdater	Applies all sub-actors to process either the selected value of the plot container.
class	PlotProcessor	Applies the specified processing algorithm to the stream of plot containers passing through.
class	RaiseError	Raises a java.lang.Error if the condition evaluates to 'true', using the provided error message. See also: adams.flow.control.TryCatch Input/output: - accepts: adams.flow.core.Unknown - generates: adams.flow.core.Unknown
class	Rejector	Rejects data containers with errors attached.
class	RemoteExecutionTrigger	Transfers the actors below itself, the specified storage items and variables using the specified connection for remote execution. Uses the adams.scripting.command.flow.RemoteFlowExecution remote command behind the scenes.
class	RemoveOutliers	Allows the user to interactively remove outliers. You can toggle the 'outlier' state of individual points by left-clicking them.You can also toggle whole regions by selecting a polygon around them: use SHIFT+left-click to place vertices and SHIFT+right-click to finish the polygon.
class	Sequence	Encapsulates a sequence of flow items.
class	SetContainerValue	Updates a single item in the container passing through, using either the data obtained from a callable actor or a storage item. Using the 'force' option, additional meta-data can be stored in the container as well.
