This test checks that annotations produce Descriptor entries as
|
|
specified in javax.management.DescriptorKey. It does two things:
|
|
|
|
- An annotation consisting of an int and a String, each with an
|
|
appropriate @DescriptorKey annotation, is placed on every program
|
|
element where it can map to a Descriptor, namely:
|
|
|
|
. on an MBean interface
|
|
. on a getter for a read-only attribute
|
|
. on a setter for a write-only attribute
|
|
. on the getter but not the setter for a read/write attribute
|
|
. on the setter but not the getter for a read/write attribute
|
|
. on both the getter and the setter for a read/write attribute
|
|
. on an operation
|
|
. on each parameter of an operation
|
|
. on a public constructor with no parameters
|
|
. on a public constructor with a parameter
|
|
. on the parameter of that public constructor
|
|
. on all of the above for an MXBean instead of an MBean
|
|
|
|
The test checks that in each case the corresponding Descriptor
|
|
appears in the appropriate place inside the MBean's MBeanInfo.
|
|
|
|
- An annotation consisting of enough other types to ensure coverage
|
|
is placed on a getter. The test checks that the generated
|
|
MBeanAttributeInfo contains the corresponding Descriptor. The tested
|
|
types are the following:
|
|
|
|
. Class
|
|
. an enumeration type (java.lang.annotation.RetentionPolicy)
|
|
. boolean
|
|
. String[]
|
|
. Class[]
|
|
. int[]
|
|
. an array of enumeration type (RetentionPolicy[])
|
|
. boolean[]
