join list of boolean elements groovy

Question

i have a list of boolean elements:

  def list=[true,false,true,true]

i ask if exist method such as following :

  list.joinBoolean('&&')

< false

Because : true && false && true && true=false

list.joinBoolean('||')

< true

Because : true || false || true || true=true

if it does not exist , i know how to do the loop to get expected result ;

AND

  boolean tmp=true;
  list.each{e->
     tmp=tmp && e;    
  }
   return tmp;

OR

  boolean tmp=false;
  list.each{e->
     tmp=tmp || e;    
  }
   return tmp;

Answer 1

Or:

list.inject { a, b -> a && b }
list.inject { a, b -> a || b }

if list can be empty, you need to use the longer inject form of:

list.inject(false) { a, b -> a && b }
list.inject(false) { a, b -> a || b }

Or use the any and every methods below

Btw

The any and every functions mentioned in the other answers work like:

list.any()
list.every()

Or (longer form)

list.any { it == true }
list.every { it == true }

Answer 2

any and every methods can come handy here
