Zend_CodeGenerator Reference
Abstract Classes and Interfaces
Zend_CodeGenerator_Abstract
The base class from which all CodeGenerator classes inherit
provides the minimal functionality necessary. It's API is as
follows:
The constructor first calls _init() (which is left
empty for the concrete extending class to implement), then
passes the $options parameter to
setOptions(), and finally calls
_prepare() (again, to be implemented by an
extending class).
Like most classes in Zend Framework, setOptions()
compares an option key to existing setters in the class, and
passes the value on to that method if found.
__toString() is marked as final, and proxies to
generate().
setSourceContent() and
getSourceContent() are intended to either set the
default content for the code being generated, or to replace said
content once all generation tasks are complete.
Zend_CodeGenerator_Php_Abstract
Zend_CodeGenerator_Php_Abstract extends
Zend_CodeGenerator_Abstract, and adds some
properties for tracking whether content has changed as well as
the amount of indentation that should appear before generated
content. Its API is as follows:
Zend_CodeGenerator_Php_Member_Abstract
Zend_CodeGenerator_Php_Member_Abstract is a base
class for generating class members -- properties and methods --
and provides accessors and mutators for establishing visibility;
whether or not the member is abstract, static, or final; and the
name of the member. Its API is as follows:
Concrete CodeGenerator Classes
Zend_CodeGenerator_Php_Body
Zend_CodeGenerator_Php_Body is intended for
generating arbitrary procedural code to include within a file.
As such, you simply set content for the object, and it will
return that content when you invoke generate().
The API of the class is as follows:
Zend_CodeGenerator_Php_Class
Zend_CodeGenerator_Php_Class is intended for
generating PHP classes. The basic functionality just generates
the PHP class itself, as well as optionally the related
PHP DocBlock. Classes may implement or inherit from other
classes, and may be marked as abstract. Utilizing other code generator
classes, you can also attach class constants, properties, and
methods.
The API is as follows:
The setProperty() method accepts an array of
information that may be used to generate a
Zend_CodeGenerator_Php_Property instance -- or
simply an instance of
Zend_CodeGenerator_Php_Property.
Likewise, setMethod() accepts either an array of
information for generating a
Zend_CodeGenerator_Php_Method instance or a
concrete instance of that class.
Note that setDocBlock() expects an instance of
Zend_CodeGenerator_Php_DocBlock.
Zend_CodeGenerator_Php_Docblock
Zend_CodeGenerator_Php_Docblock can be used to
generate arbitrary PHP docblocks, including all the standard
docblock features: short and long descriptions and annotation
tags.
Annotation tags may be set using the setTag() and
setTags() methods; these each take either an array
describing the tag that may be passed to the
Zend_CodeGenerator_Php_Docblock_Tag constructor, or
an instance of that class.
The API is as follows:
Zend_CodeGenerator_Php_Docblock_Tag
Zend_CodeGenerator_Php_Docblock_Tag is intended for
creating arbitrary annotation tags for inclusion in PHP
docblocks. Tags are expected to contain a name (the portion
immediately following the '@' symbol) and a description
(everything following the tag name).
The class API is as follows:
Zend_CodeGenerator_Php_DocBlock_Tag_Param
Zend_CodeGenerator_Php_DocBlock_Tag_Param is a
specialized version of
Zend_CodeGenerator_Php_DocBlock_Tag, and represents
a method parameter. The tag name is therefor known ("param"),
but due to the format of this annotation tag, additional
information is required in order to generate it: the parameter
name and data type it represents.
The class API is as follows:
Zend_CodeGenerator_Php_DocBlock_Tag_Return
Like the param docblock tag variant,
Zend_CodeGenerator_Php_Docblock_Tab_Return is an
annotation tag variant for representing a method return value.
In this case, the annotation tag name is known ("return"), but
requires a return type.
The class API is as follows:
Zend_CodeGenerator_Php_File
Zend_CodeGenerator_Php_File is used to generate
the full contents of a file that will contain PHP code. The file
may contain classes or arbitrary PHP code, as well as a
file-level docblock if desired.
When adding classes to the file, you will need to pass either an
array of information to pass to the
Zend_CodeGenerator_Php_Class constructor, or an
instance of that class. Similarly, with docblocks, you will need
to pass information for the
Zend_CodeGenerator_Php_Docblock constructor to
consume or an instance of the class.
The API of the class is as follows:
Zend_CodeGenerator_Php_Member_Container
Zend_CodeGenerator_Php_Member_Container is used
internally by Zend_CodeGenerator_Php_Class to keep
track of class members -- properties and methods alike. These
are indexed by name, using the concrete instances of the members
as values.
The API of the class is as follows:
Zend_CodeGenerator_Php_Method
Zend_CodeGenerator_Php_Method describes a class
method, and can generate both the code and the docblock for the
method. The visibility and status as static,
abstract, or final may be indicated, per its parent class,
Zend_CodeGenerator_Php_Member_Abstract. Finally,
the parameters and return value for the method may be specified.
Parameters may be set using setParameter() or
setParameters(). In each case, a parameter should
either be an array of information to pass to the
Zend_CodeGenerator_Php_Parameter constructor or an
instance of that class.
The API of the class is as follows:
Zend_CodeGenerator_Php_Parameter
Zend_CodeGenerator_Php_Parameter may be used to
specify method parameters. Each parameter may have a position
(if unspecified, the order in which they are registered with the
method will be used), a default value, and a data type; a
parameter name is required.
The API of the class is as follows:
There are several problems that might occur when trying to set
NULL, booleans or arrays as default values. For this the value
holder object Zend_CodeGenerator_Php_ParameterDefaultValue
can be used, for example:
setDefaultValue(
new Zend_CodeGenerator_Php_Parameter_DefaultValue("null")
);
$parameter->setDefaultValue(
new Zend_CodeGenerator_Php_Parameter_DefaultValue("array('foo', 'bar')")
);
]]>
Internally setDefaultValue() also converts the values
which can't be expressed in PHP into the value holder.
Zend_CodeGenerator_Php_Property
Zend_CodeGenerator_Php_Property describes a class
property, which may be either a constant or a variable. In each
case, the property may have an optional default value associated
with it. Additionally, the visibility of variable properties may
be set, per the parent class,
Zend_CodeGenerator_Php_Member_Abstract.
The API of the class is as follows:
