BaseSelectorContainer

Extends \BaseSelector Implements \SelectorContainer

This is the base class for selectors that can contain other selectors.

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)

package

phing.types.selectors

Methods

Indicates whether there are any selectors here.

hasSelectors() 

Gives the count of the number of selectors in this container

selectorCount() 

Returns a copy of the selectors as an array.

getSelectors(\Project $p) 

Arguments

Returns an array for accessing the set of selectors (not a copy).

selectorElements() 

Convert the Selectors within this container to a string. This will just be a helper class for the subclasses that put their own name around the contents listed here.

toString() : \comma

Response

\comma

separated list of Selectors contained in this one

Add a new selector into this container.

appendSelector(\FileSelector $selector) : \the

Arguments

$selector

\FileSelector

Response

\the

selector that was added

Subclasses can use this to throw the requisite exception in isSelected() in the case of an error condition.

validate() 
inherited

add a "Select" selector entry on the selector list

createSelector() 

add an "And" selector entry on the selector list

createAnd() 

add an "Or" selector entry on the selector list

createOr() 

add a "Not" selector entry on the selector list

createNot() 

add a "None" selector entry on the selector list

createNone() 

add a majority selector entry on the selector list

createMajority() 

add a selector date entry on the selector list

createDate() 

add a selector size entry on the selector list

createSize() 

add a selector filename entry on the selector list

createFilename() 

add an extended selector entry on the selector list

createCustom() 

add a contains selector entry on the selector list

createContains() 

add a contains selector entry on the selector list

createContainsRegexp() 

add a present selector entry on the selector list

createPresent() 

add a depth selector entry on the selector list

createDepth() 

add a depends selector entry on the selector list

createDepend() 

add a type selector entry on the selector list

createType() 

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

setError($msg) 
inherited

Arguments

$msg

Returns any error messages that have been set.

getError() : \the
inherited

Response

\the

error condition

<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() 
inherited

Sets a description of the current data type. It will be useful in commenting what we are doing.

setDescription($desc) 
inherited

Arguments

$desc

Return the description for the current data type.

getDescription() 
inherited

Has the refid attribute of this element been set?

isReference() 
inherited

Set the value of the refid attribute.

setRefid(\Reference $r) : void
inherited

Subclasses may need to check whether any other attributes have been set as well or child elements have been created and thus override this method. if they do they must call parent::setRefid()

Arguments

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) 
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.

Arguments

$stk

Performs the check for circular references and returns the referenced object.

getCheckedRef($requiredClass, $dataTypeName) 
inherited

Arguments

$requiredClass

$dataTypeName

Creates an exception that indicates that refid has to be the only attribute if it is set.

tooManyAttributes() 
inherited

Creates an exception that indicates that this XML element must not have child elements if the refid attribute is set.

noChildrenAllowed() 
inherited

Creates an exception that indicates the user has generated a loop of data types referencing each other.

circularReference() 
inherited

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

parsingComplete() : void
inherited

References the project to the current component.

setProject(\Project $project) 
inherited

Arguments

$project

\Project

The reference to the current project

Returns a reference to current project

getProject() : \Project
inherited

Response

\Project

Reference to current porject object

Logs a message with the given priority.

log(string $msg, integer $level = \Project::MSG_INFO) 
inherited

Arguments

$msg

string

The message to be logged.

$level

integer

The message's priority at this message should have

Properties

selectorsList

selectorsList : 

errmsg

errmsg : 
inherited

The descriptin the user has set.

description : 
inherited

Value to the refid attribute. Type of Reference

ref : 
inherited

Are we sure we don't hold circular references?

checked : boolean
inherited

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).

var

Type(s)

boolean

Holds a reference to the project that a project component (a task, a target, etc.) belongs to

project : \Project
inherited
var

A reference to the current project instance

Type(s)

\Project
