# AndSelector

Extends \BaseSelectorContainer

This selector has a collection of other selectors, all of which have to select a file in order for this selector to select it.

This class handles the common description attribute and provides a default implementation for reference handling and checking for circular references that is appropriate for types that can not be nested inside elements of the same type (i.e. patternset but not path)

## Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

    dieOnCircularReference( &$stk, \Project $p) : void

inherited

If one is included, throw a BuildException created by circularReference

This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

The general contract of this method is that it shouldn't do anything if checked is true and set it to true on exit.

## Returns a copy of the selectors as an array.

    isReference() : boolean

inherited

### Response

`boolean`

## Returns true (the file is selected) only if all other selectors agree that the file should be selected.

    isSelected(\PhingFile $basedir, string $filename, \PhingFile $file) : boolean

### Arguments

`\PhingFile`

the base directory the scan is being done from

#### $filename

inherited

### Arguments

#### $msg

    noChildrenAllowed() : \BuildException

inherited

### Response

`\BuildException`

## Template method being called when the data type has been parsed completely.

    parsingComplete() : void

inherited

    setDescription(string $desc) : void

inherited

### Arguments

#### $desc

`string`

## Allows all selectors to indicate a setup error. Note that only the first error message is recorded.

    setError(string $msg) : void

The reference to the current project

## Set the value of the refid attribute.

    setRefid(\Reference $r) : void

    validate()

inherited

throws |

## <p>Subclasses can override this method to provide checking of their state. So long as they call validate() from isSelected(), this will be called automatically (unless they override validate()).</p> <p>Implementations should check for incorrect settings and call setError() as necessary.</p>

    verifySettings()

Subclasses are responsible for setting this value to false if we'd need to investigate this condition (usually because a child element has been added that is a subclass of DataType).
