示例1: testCompile
/**
* Tests that by calling compile internal iteration operations are not done
* more than once
*
* @return void
*/
public function testCompile()
{
$items = ['a' => 1, 'b' => 2, 'c' => 3];
$collection = new Collection($items);
$callable = $this->getMock('stdClass', ['__invoke']);
$callable->expects($this->at(0))->method('__invoke')->with(1, 'a')->will($this->returnValue(4));
$callable->expects($this->at(1))->method('__invoke')->with(2, 'b')->will($this->returnValue(5));
$callable->expects($this->at(2))->method('__invoke')->with(3, 'c')->will($this->returnValue(6));
$compiled = $collection->map($callable)->compile();
$this->assertEquals(['a' => 4, 'b' => 5, 'c' => 6], $compiled->toArray());
$this->assertEquals(['a' => 4, 'b' => 5, 'c' => 6], $compiled->toArray());
}示例2: override
/**
* Set an override for a column, columns or restore all to default
*
* Pass CRUDDATA_DEFAULT_OVERRIDES (FALSE) to restore to default types for all columns
* Pass string_name, string_value to override one column
* Pass [
* string_name => string_value,
* string_name => string_value
* ] for multiple overrides at once
*
* @param array|string|boolean $override
* @param string $type
* @return array
*/
