 Methods

Create new parameters to pass to custom selector.

addParam(\Parameter $p) 

Parameters

$p

\p

The new Parameter object

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

circularReference() 
Inherited
inherited_from \DataType::circularReference()
inherited_from \BaseSelector::circularReference()

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.

inherited_from \DataType::dieOnCircularReference()
inherited_from \BaseSelector::dieOnCircularReference()

Parameters

$stk

$p

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

getCheckedRef($requiredClass, $dataTypeName) 
Inherited
inherited_from \DataType::getCheckedRef()
inherited_from \BaseSelector::getCheckedRef()

Parameters

$requiredClass

$dataTypeName

Return the description for the current data type.

getDescription() 
Inherited
inherited_from \DataType::getDescription()
inherited_from \BaseSelector::getDescription()

Returns any error messages that have been set.

getError() : \the
Inherited
inherited_from \BaseSelector::getError()

Returns

\theerror condition

Returns a reference to current project

getProject() : \Project
Inherited
inherited_from \ProjectComponent::getProject()
inherited_from \DataType::getProject()
inherited_from \BaseSelector::getProject()

Returns

\ProjectReference to current porject object

Has the refid attribute of this element been set?

isReference() 
Inherited
inherited_from \DataType::isReference()
inherited_from \BaseSelector::isReference()

Allows the custom selector to choose whether to select a file.

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

This is also where the Parameters are passed to the custom selector.

Parameters

$basedir

\basedir

A PhingFile object for the base directory

$filename

\filename

The name of the file to check

$file

\file

A PhingFile object for this filename

Exceptions

\BuildException

Returns

\whetherthe file should be selected or not

Logs a message with the given priority.

log(string $msg, integer $level) 
Inherited
inherited_from \ProjectComponent::log()
inherited_from \DataType::log()
inherited_from \BaseSelector::log()

Parameters

$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() 
Inherited
inherited_from \DataType::noChildrenAllowed()
inherited_from \BaseSelector::noChildrenAllowed()

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

parsingComplete() : void
Inherited
inherited_from \DataType::parsingComplete()
inherited_from \BaseSelector::parsingComplete()

Instantiates the identified custom selector class.

selectorCreate() 

Sets the classname of the custom selector.

setClassname(\classname $classname) 

Parameters

$classname

\classname

is the class which implements this selector

Sets a description of the current data type.

setDescription($desc) 
Inherited

It will be useful in commenting what we are doing.

inherited_from \DataType::setDescription()
inherited_from \BaseSelector::setDescription()

Parameters

$desc

Allows all selectors to indicate a setup error.

setError(\msg $msg) 
Inherited

Note that only the first error message is recorded.

inherited_from \BaseSelector::setError()

Parameters

$msg

\msg

The error message any BuildException should throw.

References the project to the current component.

setProject(\Project $project) 
Inherited
inherited_from \ProjectComponent::setProject()
inherited_from \DataType::setProject()
inherited_from \BaseSelector::setProject()

Parameters

$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()

inherited_from \DataType::setRefid()
inherited_from \BaseSelector::setRefid()

Parameters

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

tooManyAttributes() 
Inherited
inherited_from \DataType::tooManyAttributes()
inherited_from \BaseSelector::tooManyAttributes()

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

validate() 
Inherited
inherited_from \BaseSelector::validate()

These are errors specific to ExtendSelector only.

verifySettings() 

If there are errors in the custom selector, it should throw a BuildException when isSelected() is called.

 Properties

 

$description 
Inherited
inherited_from \DataType::$$description
inherited_from \BaseSelector::$$description
 

$ref 
Inherited

Type of Reference

inherited_from \DataType::$$ref
inherited_from \BaseSelector::$$ref
 

$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).

inherited_from \DataType::$$checked
inherited_from \BaseSelector::$$checked
 

$project : \Project
Inherited
inherited_from \ProjectComponent::$$project
inherited_from \DataType::$$project
inherited_from \BaseSelector::$$project
 

$classname 
 

$dynselector 
 

$errmsg 
Inherited
inherited_from \BaseSelector::$$errmsg
