Package javax.print.attribute.standard
|
|
31 |
contains classes for specific printing attributes.
|
|
32 |
The parent package,
|
|
33 |
<A HREF="../package-summary.html">
|
|
34 |
javax.print.attribute</A>,
|
|
35 |
provides classes and interfaces that describe the types of Java
|
|
36 |
Print Service attributes and how they can be collected into attribute
|
|
37 |
sets.
|
|
38 |
<P>
|
|
39 |
An attribute represents a printing feature
|
|
40 |
that a print service can provide.
|
|
41 |
For each attribute,
|
|
42 |
a print service either does or does not support the attribute.
|
|
43 |
For each possible value of a supported attribute,
|
|
44 |
a print service either does or does not support the value.
|
|
45 |
<P>
|
|
46 |
The API requires every print service
|
|
47 |
to support certain attributes;
|
|
48 |
other attributes are optional
|
|
49 |
and the service can choose whether or not to support them.
|
|
50 |
Each attribute has a set of values that it accepts. The API
|
|
51 |
requires every print service to support certain values for
|
|
52 |
certain attributes;
|
|
53 |
other attribute values are optional
|
|
54 |
and the service can choose whether or not to support them.
|
|
55 |
These support requirements are recorded in the documentation
|
|
56 |
for each attribute class.
|
|
57 |
<P>
|
|
58 |
Package javax.print.attribute.standard
|
|
59 |
contains standard printing attributes
|
|
60 |
and standard printing attribute values
|
|
61 |
that are widely used in the printing domain.
|
|
62 |
A print service vendor
|
|
63 |
can provide new vendor-specific printing attributes
|
|
64 |
in addition to the standard ones.
|
|
65 |
A vendor can also provide
|
|
66 |
vendor-specific extensions (subclasses)
|
|
67 |
of the standard printing attributes --
|
|
68 |
for example,
|
|
69 |
to provide additional vendor-specific values
|
|
70 |
for an existing standard attribute.
|
|
71 |
Of course,
|
|
72 |
if a vendor wants clients
|
|
73 |
to be able to use any added or extended attributes,
|
|
74 |
the vendor must publish the new attribute classes.
|
|
75 |
<P>
|
|
76 |
Many of the standard attribute classes extend one of
|
|
77 |
the abstract syntax classes of the javax.print.attribute package.
|
|
78 |
These abstract syntax classes each represent a
|
|
79 |
different type. The <a href="../EnumSyntax.html">
|
|
80 |
EnumSyntax</a> class, for example, represents a type-safe
|
|
81 |
enumeration. The abstract syntax class provides a wrapper for the attribute
|
|
82 |
value.
|
|
83 |
<p>
|
|
84 |
If an attribute class extends <code>EnumSyntax</code>, and the value of the
|
|
85 |
attribute is an IPP-compatible value, the attribute's <code>toString</code>
|
|
86 |
method returns the IPP string representation of the attribute value, such as
|
|
87 |
"processing-stopped" for the
|
|
88 |
<a href="JobState.html">JobState</a> attribute. However, because the
|
|
89 |
<code>EnumSyntax</code> class is extensible, vendors can define their own
|
|
90 |
attribute values. If an attribute uses the <code>EnumSyntax</code> class
|
|
91 |
and is set to one of these vendor-defined values then the <code>toString</code>
|
|
92 |
method will not return the IPP string representation of the value.
|
|
93 |
<p>
|
|
94 |
A printing client application
|
|
95 |
will typically not need to use
|
|
96 |
all the printing attribute classes
|
|
97 |
in package javax.print.attribute.standard,
|
|
98 |
just the ones that pertain to the application.
|
|
99 |
<P>
|
|
100 |
The attribute classes in package javax.print.attribute.standard
|
|
101 |
are based on the Internet Printing Protocol (IPP) attributes
|
|
102 |
as defined in the Internet RFC document,
|
|
103 |
<I>RFC 2911 Internet Printing Protocol/1.1: Model and Semantics</I>
|
|
104 |
dated September 2000.
|
|
105 |
See <a HREF="http://www.ietf.org/rfc/rfc2911.txt">RFC 2911</a>
|
|
106 |
for more information.
|
|
107 |
The descriptive text for each attribute class
|
|
108 |
was taken largely from the above documents.
|
|
109 |
The above authors' contribution to the API
|
|
110 |
is gratefully acknowledged.

<H3>Attribute Organization</H3>
|
|
113 |
There are five kinds of printing attributes:
|
|
114 |
doc attributes,
|
|
115 |
print request attributes,
|
|
116 |
print job attributes,
|
|
117 |
print service attributes,
|
|
118 |
and supported-values attributes.
|
|
119 |
|
|
120 |
<H4>Doc Attributes</H4>
|
|
121 |
Doc attributes specify the characteristics of an individual doc
|
|
122 |
and the print job settings to be applied to an individual doc.
|
|
123 |
A doc attribute class implements interface
|
|
124 |
<A HREF="../DocAttribute.html">DocAttribute</A>.
|
|
125 |
A doc attribute can appear in a
|
|
126 |
<a href="../DocAttributeSet.html">
|
|
127 |
DocAttributeSet</a>.
|
|
128 |
|
|
129 |
<H4>Print Request Attributes</H4>
|
|
130 |
Print request attributes
|
|
131 |
specify the settings to be applied to a whole print job
|
|
132 |
and to all the docs in the print job.
|
|
133 |
A print request attribute class implements interface
|
|
134 |
<A HREF="../PrintRequestAttribute.html">
|
|
135 |
PrintRequestAttribute</A>.
|
|
136 |
A print request attribute can appear in a
|
|
137 |
<a href="../PrintRequestAttributeSet.html">
|
|
138 |
PrintRequestAttributeSet</a>.
|
|
139 |
|
|
140 |
<P>
|
|
141 |
Some attributes are doc attributes
|
|
142 |
but not print request attributes
|
|
143 |
and may only be specified at the doc level.
|
|
144 |
Some attributes are print request attributes
|
|
145 |
but not doc attributes
|
|
146 |
and may only be specified at the Print Request level.
|
|
147 |
Some attributes are both doc attributes
|
|
148 |
and print request attributes
|
|
149 |
and may be specified either at the doc level
|
|
150 |
or at the Print Request level.
|
|
151 |
<P>
|
|
152 |
When specified at the doc level,
|
|
153 |
an attribute applies just to that one doc.
|
|
154 |
When specified at the Print Request level,
|
|
155 |
an attribute applies to the whole job,
|
|
156 |
including all the docs in the job.
|
|
157 |
However, an attribute specified at the doc level
|
|
158 |
overrides an attribute in the same category
|
|
159 |
specified at the Print Request level.
|
|
160 |
|
|
161 |
<H4>Print Job Attributes</H4>
|
|
162 |
Print job attributes report the status of a Print Job.
|
|
163 |
A print job attribute class implements interface
|
|
164 |
<A HREF="../PrintJobAttribute.html">PrintJobAttribute</A>.
|
|
165 |
A print job attribute
|
|
166 |
can appear in a <A HREF="../PrintJobAttributeSet.html">
|
|
167 |
PrintJobAttributeSet</A>.
|
|
168 |
<P>
|
|
169 |
Some attributes are both print request attributes
|
|
170 |
and print job attributes;
|
|
171 |
a client may include such attributes in a Print Request
|
|
172 |
to specify characteristics for the ensuing Print Job,
|
|
173 |
and those attributes then also appear
|
|
174 |
in the Print Job's attribute set.
|
|
175 |
Some attributes are print job attributes
|
|
176 |
but not print request attributes;
|
|
177 |
the print service itself
|
|
178 |
adds these attributes to the Print Job's attribute set.
|
|
179 |
|
|
180 |
<H4>Print Service Attributes</H4>
|
|
181 |
Print service attributes report the status
|
|
182 |
of a print service.
|
|
183 |
A print service attribute class implements interface
|
|
184 |
<A HREF="../PrintServiceAttribute.html">
|
|
185 |
PrintServiceAttribute</A>.
|
|
186 |
A print service attribute
|
|
187 |
can appear in a <A HREF="../PrintServiceAttributeSet.html">
|
|
188 |
PrintServiceAttributeSet</A>.
|
|
189 |
|
|
190 |
<H4>Supported-Values Attributes</H4>
|
|
191 |
A supported-value attribute
|
|
192 |
indicates the legal values for another attribute
|
|
193 |
that a print service supports.
|
|
194 |
A supported-values attribute class implements interface
|
|
195 |
<A HREF="../SupportedValuesAttribute.html">
|
|
196 |
SupportedValuesAttribute</A>.
|
|
197 |
However, supported-values attributes
|
|
198 |
never appear in attribute sets,
|
|
199 |
so there is no restricted <A HREF="../AttributeSet.html">
|
|
200 |
AttributeSet</A>
|
|
201 |
subinterface for them.
|
|
202 |
<P>
|
|
203 |
|
|
204 |
<H4>Attribute Table</H4>
|
|
205 |
The table below lists all the printing attributes.
|
|
206 |
The table shows the tagging interfaces
|
|
207 |
each attribute class implements
|
|
208 |
in addition to interface <A HREF="../Attribute.html">
|
|
209 |
Attribute</A>,
|
|
210 |
thus indicating how each attribute is used in the API.
|
|
211 |
For each doc attribute and print request attribute,
|
|
212 |
the column marked "SupportedValuesAttribute"
|
|
213 |
lists the supported-values attribute class, if any,
|
|
214 |
with which a print service
|
|
215 |
indicates the supported values for that attribute category.
|
|
216 |
<P>

<P>
|
|
284 |
Please note: In the javax.print APIs, a null reference parameter to methods
|
|
285 |
is incorrect unless explicitly documented on the method as having a meaningful
|
|
286 |
interpretation. Usage to the contrary is incorrect coding and may result
|
|
287 |
in a run time exception either immediately or at some later time.
|
|
288 |
IllegalArgumentException and NullPointerException are examples of
|
|
289 |
typical and acceptable run time exceptions for such cases.
