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

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.
