Detailed Description

Consumes a string and outputs boolean "true" if the text represents a human readable version of "true".

The following case-insensitive values are considered true:

  • True
  • T
  • Yes
  • Y
  • On
  • Any string that represents a non-zero number

Member Function Documentation

◆ is_valid_false()

bool sensesp::TextToTruth::is_valid_false ( const String & value)
static

Returns TRUE if value represents one of the boolean values recognized as a "false" value. FALSE is returned if value is a value that is normally associated with a boolean false.

Definition at line 25 of file truth_text.cpp.

◆ is_valid_true()

bool sensesp::TextToTruth::is_valid_true ( const String & value)
static

Returns TRUE if value represents one of the truth values recognized by TextToTruth

Definition at line 7 of file truth_text.cpp.

Here is the caller graph for this function:

◆ set()

void sensesp::TextToTruth::set ( const String & new_value)
overridevirtual

Used to set an input of this consumer. It is called automatically by a ValueProducer but can also be called manually.

Parameters
new_valuethe value of the input

Reimplemented from sensesp::ValueConsumer< String >.
