Clear

Name	Mandatory	Description	Default	Type
⬅️ Input		Any input is ignored.		Any
Output ➡️		The input is passed through as the output.		Any
Name	No	The name of the variable.	``	String&Any
Key	Yes	The key of the value to read from the table (parameter applicable only if the target variable is a table).	None	Any
Global	No	If the variable is available to all of the wires in the same mesh.	false	Bool

Clears all elements from the sequence or table passed to it. Applicable only to sequences and tables. For sequences, this operation is very fast as Shards recycles memory extensively. If the variable does not exist or the type is not a sequence or table, it simply passes through without failing.

Examples

Code

[1 2 3] >= seq ; ; create local sequence
seq | Log ; ; read local sequence  => [1, 2, 3]

Clear(Name: seq) ; ; clear local sequence
seq | Log ; ; local sequence cleared => []

100 | AppendTo(seq) ; ; append something to local sequence
seq | Log ; ; local sequence no more empty => [100]

Clear(Name: seq) ; ; clear
seq | Log
