The read-resource operation

Reads a management resource's attribute values along with either basic or complete information about any child resources. Supports the
following parameters, none of which are required:

• recursive – (boolean, default is false) – whether to include complete information about child resources, recursively.

• recursive-depth – (int) – The depth to which information about child resources should be included if recursive is {{true}. If not set, the depth will be unlimited; i.e. all descendant resources will be included.

• proxies – (boolean, default is false) – whether to include remote resources in a recursive query (i.e. host level resources from slave Host Controllers in a query of the Domain Controller; running server resources in a query of a host).

• include-runtime – (boolean, default is false) – whether to include runtime attributes (i.e. those whose value does not come from the persistent configuration) in the response.

• include-defaults – (boolean, default is true) – whether to include in the result default values not set by users. Many attributes have a default value that will be used in the runtime if the users have not provided an explicit value. If this parameter is false the value for such attributes in the result will be undefined. If true the result will include the default value for such parameters.

The read-attribute operation

Reads the value of an individual attribute. Takes a single, required, parameter:

• name – (string) – the name of the attribute to read.

• include-defaults – (boolean, default is true) – whether to include in the result default values not set by users. Many attributes have a default value that will be used in the runtime if the users have not provided an explicit value. If this parameter is false the value for such attributes in the result will be undefined. If true the result will include the default value for such parameters.

The write-attribute operation

Writes the value of an individual attribute. Takes two required parameters:

• name – (string) – the name of the attribute to write.

• value – (type depends on the attribute being written) – the new value.

The unset-attribute operation

Sets the value of an individual attribute to the undefined value, if such a value is allowed for the attribute. The operation will fail if the undefined value is not allowed. Takes a single required parameter:

• name – (string) – the name of the attribute to write.

The read-resource-description operation

Returns the description of a resource's attributes, types of children and, optionally, operations. Supports the
following parameters, none of which are required:

• recursive – (boolean, default is false) – whether to include information about child resources, recursively.

• proxies – (boolean, default is false) – whether to include remote resources in a recursive query (i.e. host level resources from slave Host Controllers in a query of the Domain Controller; running server resources in a query of a host)

• operations – (boolean, default is false) – whether to include descriptions of the resource's operations

• inherited – (boolean, default is true) – if operations is true, whether to include descriptions of operations inherited from higher level resources. The global operations described in this section are themselves inherited from the root resource, so the primary effect of setting inherited to false is to exclude the descriptions of the global operations from the output.

See Description of the Management Model for details on the result of this operation.

The read-operation-names operation

Returns a list of the names of all the operations the resource supports. Takes no parameters.

The read-operation-description operation

Returns the description of an operation, along with details of its parameter types and its return value. Takes a single, required, parameter:

• name – (string) – the name of the operation

See Description of the Management Model for details on the result of this operation.

The read-children-types operation

Returns a list of the types of child resources the resource supports. Takes no parameters.

The read-children-names operation

Returns a list of the names of all child resources of a given type. Takes a single, required, parameter:

• child-type – (string) – the name of the type

The read-children-resources operation

Returns information about all of a resource's children that are of a given type. For each child resource, the returned information is equivalent to executing the read-resource operation on that resource. Takes the following parameters, of which only {{child-type} is required:

• child-type – (string) – the name of the type of child resource

• recursive – (boolean, default is false) – whether to include complete information about child resources, recursively.

• recursive-depth – (int) – The depth to which information about child resources should be included if recursive is {{true}. If not set, the depth will be unlimited; i.e. all descendant resources will be included.

• proxies – (boolean, default is false) – whether to include remote resources in a recursive query (i.e. host level resources from slave Host Controllers in a query of the Domain Controller; running server resources in a query of a host)

• include-runtime – (boolean, default is false) – whether to include runtime attributes (i.e. those whose value does not come from the persistent configuration) in the response.

• include-defaults – (boolean, default is true) – whether to include in the result default values not set by users. Many attributes have a default value that will be used in the runtime if the users have not provided an explicit value. If this parameter is false the value for such attributes in the result will be undefined. If true the result will include the default value for such parameters.

Standard Operations

Besides the global operations described above, by convention nearly every resource should expose an add operation and a remove operation. Exceptions to this convention are the root resource, and resources that do not store persistent configuration and are created dynamically at runtime (e.g. resources representing the JVM's platform mbeans or resources representing aspects of the running state of a deployment.)
