Rubix Wires: Filter Nodes


This article describes the Rubix Wires nodes that are in the Filter category.

Filter

The Filter category of nodes provide in-line data filtering.  For each type of Filter node, only the `input` values that meet the (node specific) filter conditions are passed to `output`.

Only-True

This node filters `input` values and only allows `true` values to be passed to `output`.

Inputs

  1. input - Input value to be filtered.

Outputs

  1. output - Boolean `true` is the only possible output value (other than `null`). 

Settings

  1. Name - Name of the node.

Operation

This node filters ‘input’ values.  Only ‘true’ values are passed to ‘output’.

Only-False

This node filters `input` values and only allows `false` to be passed to `output`.

Inputs

  1. input - Input value to be filtered.

Outputs

  1. output - Boolean `false` is the only possible output value (other than `null`). 

Settings

  1. Name - Name of the node.

Operation

This node filters ‘input’ values. Only ‘false’ values are passed to ‘output’.

Only-Between

This node filters input `value` and only allows numeric values between configured `min` and `max` limits to be passed to output `value`. 

Inputs

  1. value - Numeric value to be filtered.
  2. [min] - Minimum limit value.  Values less than `min` will not be passed to `output`.
  3. [max] - Maximum limit value.  Values greater than `max` will not be passed to `output`.

Outputs

  1. value - Numeric output value.

Settings

  1. Name - Name of the node.
  2. Min - Minimum limit value.  Values less than `min` will not be passed to `output`.  Fallback from wired input value.
  3. Max - Maximum limit value.  Values greater than `max` will not be passed to `output`.  Fallback from wired input value.

Operation

This node filters input ‘value’.  Only values between ‘min’ and ‘max’ are passed to ‘value’ output.

Only-Greater

This node filters `input` values and only allows numeric values greater than configured `threshold` to be passed to `output`. 

Inputs

  1. input - Input value to be filtered.
  2. [threshold] - Minimum limit value.  Values less than `threshold` will not be passed to `output`. 

Outputs

  1. output - Numeric output value.

Settings

  1. Name - Name of the node.
  2. Threshold - Minimum limit value.  Values less than `threshold` will not be passed to `output`.  Fallback from wired input value.

Operation

This node filters ‘input’ values.  Only Numeric ‘input’ values greater than ‘threshold’ are passed to ‘output’.

Only-Lower

This node filters `input` values and only allows numeric values less than configured `threshold` to be passed to `output`. 

Inputs

  1. input - Input value to be filtered.
  2. [threshold] - Maximum limit value.  Values greater than `threshold` will not be passed to `output`. 

Outputs

  1. output - Numeric output value.

Settings

  1. Name - Name of the node.
  2. Threshold - Maximum limit value.  Values greater than `threshold` will not be passed to `output`.  Fallback from wired input value.

Operation

This node filters ‘input’ values.  Only Numeric ‘input’ values less than ‘threshold’ are passed to ‘output’.

Only-Equal

This node filters `input` values and only allows values equal to the configured `match` value to be passed to `output`. 

Inputs

  1. input - Input value to be filtered.
  2. [match] - Value to be compared against.  Only `input` values that are equal to `match` value will be passed to `output`.

Outputs

  1. output - Output value.  `match` value is the only possible output value (other than `null`). 

Settings

  1. Name - Name of the node.
  2. Match Value - Value to be compared against.  Only `input` values that are equal to `match` value will be passed to `output`.  Fallback from wired input value.

Operation

This node filters ‘input’ values.  Only ‘input’ values equal to ‘match’ are passed to ‘output’.

Prevent-Null

This node filters `input` values and does not allow `null` to be passed to `output`.

Inputs

  1. input - Input value to be filtered.

Outputs

  1. output - Output value.  Value will match `input` unless `input` is `null`, then `output` will be the last non-null value.

Settings

  1. Name - Name of the node.

Operation

This node filters ‘input’ values.  All ‘input’ values are passed to ‘output’ except ‘null’.  When `input` is `null`, `output` will be the last non-null value.

Prevent-Equal

This node filters `input` values and does not allow values equal to `match` value to be passed to `output`.

Inputs

  1. input - Input value to be filtered.
  2. [match] - Value to be filtered.  Only `input` values that are NOT EQUAL to `match` value will be passed to `output`. 

Outputs

  1. output - Value will match `input` unless `input` value is equal to `match` value, then `output` will be the last `input` value not equal to `match`.

Settings

  1. Name - Name of the node.
  2. Match Value - Value to be filtered.  Only `input` values that are NOT EQUAL to `match` value will be passed to `output`.  Fallback from wired input value.

Operation

This node filters ‘input’ values.  All ‘input’ values are passed to ‘output’ EXCEPT ‘input’ values which are equal to ‘match’ value.

Prevent-Duplicates

This node filters `input` values, it does not allow repeated values to be passed to `output`.

Inputs

  1. input - Input value to be filtered.

Outputs

  1. output - Value will always match `input`, however if the `input` value is sent multiple times, only the first occurance will be send to `output`.

Settings

  1. Name - Name of the node.

Operation

This node filters ‘input’ values.  All ‘input’ values are passed to ‘output’ EXCEPT ‘input’ values which are equal to the previous ‘input’ value.
