A string is a series of characters and what you are reading here right now is already a string. Since strings consist of a sequence of numbers, words or single characters, it is possible to perform various operations with them: different strings can be combined, keywords can be filtered, numbers can be converted into strings, or folder names can be assembled to a complete path. It is also possible to sort a string or extract a certain part of it. The graph engine's "String" nodes offer various helpers for complex tasks – even for arrays with multiple string entries.
Nodes
| Name | Description |
|---|---|
| ArrayStringConcat | This node concatenates the inputs 'array0' and 'array1' into a single 'out' array. |
| ArrayStringConstant | This node returns a constant array. |
| ArrayStringFilterByMask | This node returns the elements of the input 'array' at positions specified by the 'mask' parameter. |
| ArrayStringFindAllElementIndices | This node returns all positions in the input 'array', which fit to the input 'element' values. |
| ArrayStringFindElement | This node returns the first position of appearance of the input 'element' within the input 'array'. If the array does not contain the element, -1 is returned. |
| ArrayStringInsertElement | This node inserts all elements from the 'element' input into the input 'array' at the position specified by 'position'. If 'position' is equal or lower than 0 then the elements are inserted at the beginning of the array. If 'position' is greater or equal than the inputs 'array' size, elements are appended at the end. |
| ArrayStringMix | This node creates an output array based on the two inputs 'array0' and 'array1' and the input mask. If the mask value equals 0 then the value of 'array0' is used, if the mask value is 1 the value of 'array1' is used. |
| ArrayStringPushElement | This node appends all the elements from the 'element' at the end of the input 'array'. |
