Properties

boolean
$checked= 'true'
Are we sure we don't hold circular references?
Inherited from: \DataType::$$checked\BaseSelector::$$checkedSubclasses 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

addParam(
\p $p
)
:
voidCreate new parameters to pass to custom selector.
| Name | Type | Description |
|---|---|---|
| $p | \p | The new Parameter object |

circularReference(
)
:
voidCreates an exception that indicates the user has generated a loop of data types referencing each other.
Inherited from: \DataType::circularReference()\BaseSelector::circularReference()
dieOnCircularReference(
$stk, $p
)
:
voidCheck 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()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.
| Name | Type | Description |
|---|---|---|
| $stk | ||
| $p |

getCheckedRef(
$requiredClass, $dataTypeName
)
:
voidPerforms the check for circular references and returns the referenced object.
Inherited from: \DataType::getCheckedRef()\BaseSelector::getCheckedRef()| Name | Type | Description |
|---|---|---|
| $requiredClass | ||
| $dataTypeName |

getDescription(
)
:
voidReturn the description for the current data type.
Inherited from: \DataType::getDescription()\BaseSelector::getDescription()
getProject(
)
:
void
isReference(
)
:
voidHas the refid attribute of this element been set?
Inherited from: \DataType::isReference()\BaseSelector::isReference()
isSelected(
\basedir $basedir, \filename $filename, \file $file
)
:
\whetherAllows the custom selector to choose whether to select a file. This is also where the Parameters are passed to the custom selector.
| 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 |
| Type | Description |
|---|---|
| \whether | the file should be selected or not |
| Exception | Description |
|---|---|
| \BuildException |

noChildrenAllowed(
)
:
voidCreates 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()
parsingComplete(
)
:
voidTemplate method being called when the data type has been parsed completely.
Inherited from: \DataType::parsingComplete()\BaseSelector::parsingComplete()
setClassname(
\classname $classname
)
:
voidSets the classname of the custom selector.
| Name | Type | Description |
|---|---|---|
| $classname | \classname | is the class which implements this selector |

setDescription(
$desc
)
:
voidSets a description of the current data type. It will be useful in commenting what we are doing.
Inherited from: \DataType::setDescription()\BaseSelector::setDescription()| Name | Type | Description |
|---|---|---|
| $desc |

setError(
\msg $msg
)
:
voidAllows all selectors to indicate a setup error. Note that only the first error message is recorded.
Inherited from: \BaseSelector::setError()| Name | Type | Description |
|---|---|---|
| $msg | \msg | The error message any BuildException should throw. |

setProject(
)
:
void
setRefid(
\Reference $r
)
:
voidSet the value of the refid attribute.
Inherited from: \DataType::setRefid()\BaseSelector::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()
| Name | Type | Description |
|---|---|---|
| $r | \Reference |

tooManyAttributes(
)
:
voidCreates an exception that indicates that refid has to be the only attribute if it is set.
Inherited from: \DataType::tooManyAttributes()\BaseSelector::tooManyAttributes()
validate(
)
:
voidSubclasses can use this to throw the requisite exception in isSelected() in the case of an error condition.
Inherited from: \BaseSelector::validate()
