EvaluateDataTableValues

typed block

Factories

`EvaluateDataTableValues`

EvaluateDataTableValues() -> EvaluateDataTableValuesHandle

Construct a fresh EvaluateDataTableValues block with an auto-generated id.

Use this when authoring from scratch, the runtime picks a UUID automatically.

`EvaluateDataTableValues`

EvaluateDataTableValues(id: String) -> EvaluateDataTableValuesHandle

Construct a EvaluateDataTableValues block with an operator-supplied id.

Parameter	Type	Required	Description
`id`	`String`	yes	Wire identifier, typically a Connect UUID restored by `decompile` so round-trips stay byte-stable.

Methods

`data_table_id`

data_table_id(value: String) -> EvaluateDataTableValuesHandle

Set the DataTableId parameter. The data table to evaluate against: its ARN or a JSONPath reference. Measured 2026-10-14: Connect accepts any non-empty string and a number, and refuses the empty string, a boolean, an object and an array.

Parameter	Type	Required	Description
`value`	`String`	yes	The data table to evaluate against: its ARN or a JSONPath reference. Measured 2026-10-14: Connect accepts any non-empty string and a number, and refuses the empty string, a boolean, an object and an array.

`queries`

queries(value: Array<Map (Query)>) -> EvaluateDataTableValuesHandle

Set the Queries parameter. Structured array of data-table queries the action evaluates against. Each Query declares a QueryName, the Attributes to project, and the PrimaryValues (filter keys) to bind. Operators authoring in Rhai pass a Vec<Query> (Rhai array of map literals) directly. Measured 2026-10-14: Connect accepts one query in place of the array, and refuses [], a JSONPath and any other string or number.

Parameter	Type	Required	Description
`value`	`Array<Map (Query)>`	yes	Structured array of data-table queries the action evaluates against. Each `Query` declares a `QueryName`, the `Attributes` to project, and the `PrimaryValues` (filter keys) to bind. Operators authoring in Rhai pass a `Vec<Query>` (Rhai array of map literals) directly. Measured 2026-10-14: Connect accepts one query in place of the array, and refuses `[]`, a JSONPath and any other string or number.

`next`

next(target: Handle) -> EvaluateDataTableValuesHandle

Wire the success-path transition. Substitutes the target's auto-generated UUID into the wire Transitions.NextAction slot.

Parameter	Type	Required	Description
`target`	`Handle`	yes	The block to route to once this block completes successfully.

`on_no_matching`

on_no_matching(target: Handle) -> EvaluateDataTableValuesHandle

Wire an error transition for NoMatchingError: Route to take when Connect rejects the EvaluateDataTableValues action (most commonly: malformed Queries shape or the runtime evaluation failing on the referenced data table). Connect's structural validator requires Errors[NoMatchingError] on EDTV even though the doc-inferred block-def did not declare it.

Parameter	Type	Required	Description
`target`	`Handle`	yes	Block to route to on `NoMatchingError`. Route to take when Connect rejects the EvaluateDataTableValues action (most commonly: malformed Queries shape or the runtime evaluation failing on the referenced data table). Connect's structural validator requires `Errors[NoMatchingError]` on EDTV even though the doc-inferred block-def did not declare it.

`set_id`

set_id(id: String) -> EvaluateDataTableValuesHandle

Override the auto-generated identifier with a specific wire id.

Parameter	Type	Required	Description
`id`	`String`	yes	Wire identifier override. Decompile threads this through to round-trip Connect-side UUIDs.

`meta_position`

meta_position(x: i64, y: i64) -> EvaluateDataTableValuesHandle

Set the block's canvas position. Mostly auto-emitted by decompile; authored scripts call Flow.auto_layout() instead and let the layout pass fill positions in.

Parameter	Type	Required	Description
`x`	`i64`	yes	Canvas X coordinate.
`y`	`i64`	yes	Canvas Y coordinate.

`set_meta`

set_meta(key: String, value: Dynamic) -> EvaluateDataTableValuesHandle

Single-key escape hatch, set one ActionMetadata key by name when the typed meta_* setters don't cover it.

Parameter	Type	Required	Description
`key`	`String`	yes	Wire key name (under `Metadata.ActionMetadata[<id>]`).
`value`	`Dynamic`	yes	Any JSON-serializable Rhai value.

`overwrite_meta`

overwrite_meta(value: Map) -> EvaluateDataTableValuesHandle

Full-replace escape hatch, overwrite the entire ActionMetadata blob.

Parameter	Type	Required	Description
`value`	`Map`	yes	Replacement map for the entire ActionMetadata sub-object.

`set_meta_param`

set_meta_param(param: String, flag: String, value: Dynamic) -> EvaluateDataTableValuesHandle

Set a single per-parameter ActionMetadata flag.

Parameter	Type	Required	Description
`param`	`String`	yes	Parameter name (e.g. `"Text"`).
`flag`	`String`	yes	Flag name (`"useDynamic"`, `"MFLAG_*"`, etc.).
`value`	`Dynamic`	yes	Flag value.

`overwrite_meta_param`

overwrite_meta_param(param: String, value: Map) -> EvaluateDataTableValuesHandle

Replace the entire flag map for one parameter.

Parameter	Type	Required	Description
`param`	`String`	yes	Parameter name.
`value`	`Map`	yes	Replacement flag map for the parameter.

`overwrite_parameters`

overwrite_parameters(value: Map) -> EvaluateDataTableValuesHandle

Wire-shape escape hatch, overwrite the entire Parameters blob.

Parameter	Type	Required	Description
`value`	`Map`	yes	Replacement parameter map for the block.

`raw_transitions`

raw_transitions(value: Map) -> EvaluateDataTableValuesHandle

Wire-shape escape hatch for non-canonical transition objects.

Parameter	Type	Required	Description
`value`	`Map`	yes	Replacement transitions map (raw JSON shape).
