Phase 1 - Provide MOXy annotation support equivalent to our XML metadata support
This phase of development involves providing MOXy annotation support equivalent to the existing EclipseLink XML metadata support
Annotations
The following annotations will be targeted in this phase:
Annotation | XML Metadata Tag | Package | Type | Field | Method |
---|---|---|---|---|---|
XmlReadOnly | read-only | X | X | ||
XmlWriteOnly | write-only | X | X | ||
XmlCDATA | cdata | X | X | ||
XmlAccessMethods | xml-access-methods | X | X | ||
XmlPaths | xml-elements | X | X | ||
XmlNullPolicy | xml-null-policy | X | X | ||
XmlIsSetNullPolicy | xml-is-set-null-policy | X | X | ||
XmlIsSetParameters | n/a | X | X | ||
XmlIsSetParameter | is-set-parameter | X | X |
Example: XmlReadOnly annotation
The following example will demonstrate how the XmlReadOnly annotation can be applied:
A property can be configured to be read-only via EclipseLink XML metadata as follows:
<xml-attribute java-attribute="salary" read-only="true" />
The equivalent configured via annotations would look like:
package org.example; public class Employee { @javax.xml.bind.annotation.XmlAttribute @org.eclipse.persistence.oxm.annotations.XmlReadOnly public String salary; }
Following is the proposed XmlReadOnly annotation:
package org.eclipse.persistence.oxm.annotations; @Target({ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface XmlReadOnly {}
Example: XmlWriteOnly annotation
The following example will demonstrate how the XmlWriteOnly annotation can be applied:
A property can be configured to be write-only via EclipseLink XML metadata as follows:
<xml-attribute java-attribute="privateData" write-only="true" />
The equivalent configured via annotations would look like:
package org.example; public class Employee { @javax.xml.bind.annotation.XmlAttribute @org.eclipse.persistence.oxm.annotations.XmlWriteOnly public String privateData; }
Following is the proposed XmlWriteOnly annotation:
package org.eclipse.persistence.oxm.annotations; @Target({ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface XmlWriteOnly {}
Example: XmlCDATA annotation
The following example will demonstrate how the XmlCDATA annotation can be applied:
A property can be configured as CDATA (character data) via EclipseLink XML metadata as follows:
<xml-element java-attribute="characterData" cdata="true" />
The equivalent configured via annotations would look like:
package org.example; public class Employee { @javax.xml.bind.annotation.XmlElement @org.eclipse.persistence.oxm.annotations.XmlCDATA public String characterData; }
Following is the proposed XmlCDATA annotation:
package org.eclipse.persistence.oxm.annotations; @Target({ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface XmlCDATA {}
Example: XmlAccessMethods annotation
The following example will demonstrate how the XmlAccessMethods annotation can be applied:
A property's accessor methods can be configured via EclipseLink XML metadata as follows:
<xml-element java-attribute="firstName"> <xml-access-methods get-method="getFirstName" set-method="setFirstName" /> </xml-element>
The equivalent configured via annotations would look like:
package org.example; public class Employee { @javax.xml.bind.annotation.XmlElement @org.eclipse.persistence.oxm.annotations.XmlAccessMethods(getMethodName="getFirstName", setMethodName="setFirstName") public String firstName; }
Following is the proposed XmlAccessMethods annotation:
package org.eclipse.persistence.oxm.annotations; @Target({ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface XmlAccessMethods { String getMethodName() default ""; String setMethodName() default ""; }
