Are we sure we don't hold circular references?

Inherited from: \DataType::$$checked\BaseSelector::$$checked\BaseExtendSelector::$$checked

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).

Methods

methodpubliccircularReference( ) : void
inherited

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

Inherited from: \DataType::circularReference()\BaseSelector::circularReference()\BaseExtendSelector::circularReference()
methodpublicdieOnCircularReference(  $stk,  $p ) : void
inherited

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).

Inherited from: \DataType::dieOnCircularReference()\BaseSelector::dieOnCircularReference()\BaseExtendSelector::dieOnCircularReference()

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.

Parameters
Name Type Description
$stk
$p
methodpublicgetCheckedRef(  $requiredClass,  $dataTypeName ) : void
inherited

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

Inherited from: \DataType::getCheckedRef()\BaseSelector::getCheckedRef()\BaseExtendSelector::getCheckedRef()
Parameters
Name Type Description
$requiredClass
$dataTypeName
methodpublicgetDescription( ) : void
inherited

Return the description for the current data type.

Inherited from: \DataType::getDescription()\BaseSelector::getDescription()\BaseExtendSelector::getDescription()
methodpublicgetError( ) : \the
inherited

Returns any error messages that have been set.

Inherited from: \BaseSelector::getError()\BaseExtendSelector::getError()
Returns
Type Description
\the error condition
methodprotectedgetParameters( ) : \the
inherited

Allows access to the parameters gathered and set within the <custom> tag.

Inherited from: \BaseExtendSelector::getParameters()
Returns
Type Description
\the set of parameters defined for this selector
methodpublicgetProject( ) : \Project
Returns
Type Description
\Project Reference to current porject object
methodpublicisReference( ) : void
inherited

Has the refid attribute of this element been set?

Inherited from: \DataType::isReference()\BaseSelector::isReference()\BaseExtendSelector::isReference()
methodpublicisSelected( \basedir $basedir, \filename $filename, \file $file ) : \whether

The heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset.

Parameters
Name Type Description
$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

Returns
Type Description
\whether the file should be selected or not
methodpubliclog( string $msg, integer $level = Project::MSG_INFO ) : void
inherited

Logs a message with the given priority.

Inherited from: \ProjectComponent::log()\DataType::log()\BaseSelector::log()\BaseExtendSelector::log()
Parameters
Name Type Description
$msg string

The message to be logged.

$level integer

The message's priority at this message should have

methodpublicnoChildrenAllowed( ) : void
inherited

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

Inherited from: \DataType::noChildrenAllowed()\BaseSelector::noChildrenAllowed()\BaseExtendSelector::noChildrenAllowed()
methodpublicparsingComplete( ) : void
inherited

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

Inherited from: \DataType::parsingComplete()\BaseSelector::parsingComplete()\BaseExtendSelector::parsingComplete()
methodpublicsetDescription(  $desc ) : void
inherited

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

Inherited from: \DataType::setDescription()\BaseSelector::setDescription()\BaseExtendSelector::setDescription()
Parameters
Name Type Description
$desc
methodpublicsetError( \msg $msg ) : void
inherited

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

Inherited from: \BaseSelector::setError()\BaseExtendSelector::setError()
Parameters
Name Type Description
$msg \msg

The error message any BuildException should throw.

methodpublicsetParameters( \parameters $parameters ) : void

When using this as a custom selector, this method will be called.

It translates each parameter into the appropriate setXXX() call.

Parameters
Name Type Description
$parameters \parameters

the complete set of parameters for this selector

methodpublicsetProject( \Project $project ) : void
inherited

References the project to the current component.

Inherited from: \ProjectComponent::setProject()\DataType::setProject()\BaseSelector::setProject()\BaseExtendSelector::setProject()
Parameters
Name Type Description
$project \Project

The reference to the current project

methodpublicsetRefid( \Reference $r ) : void
inherited

Set the value of the refid attribute.

Inherited from: \DataType::setRefid()\BaseSelector::setRefid()\BaseExtendSelector::setRefid()

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()

Parameters
Name Type Description
$r \Reference
methodpublicsetUnits( \$units $units ) : void

Sets the units to use for the comparison. This is a little complicated because common usage has created standards that play havoc with capitalization rules. Thus, some people will use "K" for indicating 1000's, when the SI standard calls for "k". Others have tried to introduce "K" as a multiple of 1024, but that falls down when you reach "M", since "m" is already defined as 0.001.

<

p> To get around this complexity, a number of standards bodies have proposed the 2^10 standard, and at least one has adopted it. But we are still left with a populace that isn't clear on how capitalization should work.

<

p> We therefore ignore capitalization as much as possible. Completely mixed case is not possible, but all upper and lower forms are accepted for all long and short forms. Since we have no need to work with the 0.001 case, this practice works here.

<

p> This function translates all the long and short forms that a unit prefix can occur in and translates them into a single multiplier.

Parameters
Name Type Description
$units \$units

The units to compare the size to.

methodpublicsetValue( \size $size ) : void

A size selector needs to know what size to base its selecting on.

This will be further modified by the multiplier to get an actual size limit.

Parameters
Name Type Description
$size \size

the size to select against expressed in units

methodpublicsetWhen( \cmp $cmp ) : void

This specifies when the file should be selected, whether it be when the file matches a particular size, when it is smaller, or whether it is larger.

Parameters
Name Type Description
$cmp \cmp

The comparison to perform, an EnumeratedAttribute

methodpublictoString( ) : void

methodpublictooManyAttributes( ) : void
inherited

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

Inherited from: \DataType::tooManyAttributes()\BaseSelector::tooManyAttributes()\BaseExtendSelector::tooManyAttributes()
methodpublicvalidate( ) : void
inherited

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

Inherited from: \BaseSelector::validate()\BaseExtendSelector::validate()
methodpublicverifySettings( ) : void

Checks to make sure all settings are kosher. In this case, it means that the size attribute has been set (to a positive value), that the multiplier has a valid setting, and that the size limit is valid. Since the latter is a calculated value, this can only fail due to a programming error.

If a problem is detected, the setError() method is called.
