phing.types.selectors

Methods

Create new parameters to pass to custom selector.

addParam(\Parameter $p) : void

Arguments

$p

\Parameter

The new Parameter object

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

circularReference() : \BuildException
inherited

Response

\BuildException

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.

throws

Arguments

$stk

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

getCheckedRef( $requiredClass,  $dataTypeName) : mixed
inherited
throws

Arguments

$requiredClass

$dataTypeName

Response

mixed

Return the description for the current data type.

getDescription() 
inherited
retujrn

string

Returns any error messages that have been set.

getError() : string
inherited

Response

string

the error condition

Returns a reference to current project

getProject() : \Project
inherited

Response

\Project

Reference to current porject object

Has the refid attribute of this element been set?

isReference() : boolean
inherited

Response

boolean

Allows the custom selector to choose whether to select a file. This is also where the Parameters are passed to the custom selector.

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

Arguments

$basedir

\PhingFile

$filename

string

The filename

$file

\PhingFile

Response

\whether

Logs a message with the given priority.

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

Arguments

$msg

string

The message to be logged.

$level

integer

The message's priority at this message should have

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

noChildrenAllowed() : \BuildException
inherited

Response

\BuildException

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

parsingComplete() : void
inherited

{@inheritdoc}

Instantiates the identified custom selector class.

selectorCreate() 

Sets the classname of the custom selector.

setClassname(string $classname) 

Arguments

$classname

string

is the class which implements this selector

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

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
inherited

Arguments

$msg

string

The error message any BuildException should throw.

References the project to the current component.

setProject(\Project $project) : void
inherited

Arguments

$project

\Project

The reference to the current project

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

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

tooManyAttributes() : \BuildException
inherited

Response

\BuildException

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

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() 
inherited

Properties

classname

classname : 

Type(s)

dynselector :

description : string
inherited
var

Type(s)

string

Value to the refid attribute.

ref : \Reference
inherited
var

Type(s)

\Reference

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)
