Method Summary

SchemaNode	getSchemaNode() Returns the root node of the schema.
void	setAccessRuleOnInstance(AccessRule aRule) Declares that the global access to an instance of the schema may be restricted by the rule specified.
void	setAccessRuleOnNode(Path aPath, AccessRule aRule) Declares that the access to a node may be restricted by the rule specified.
void	setAccessRuleOnNodeAndAllDescendants(Path subTreePath, boolean includeSubTreeRoot, AccessRule aRule) Declares that the access to a nodes subtree may be restricted by the rule specified.

Method Detail

getSchemaNode

public SchemaNode getSchemaNode()

Returns the root node of the schema.

setAccessRuleOnInstance

public void setAccessRuleOnInstance(AccessRule aRule)

Declares that the global access to an instance of the schema may be restricted by the rule specified.

Parameters:

aRule - specifies the rule to assign

setAccessRuleOnNode(Path, AccessRule), setAccessRuleOnOccurrence(Path, AccessRule)

setAccessRuleOnNode

public void setAccessRuleOnNode(Path aPath,
                                AccessRule aRule)

Declares that the access to a node may be restricted by the rule specified.

At runtime, the actual access permission to a node is the minimal permission of the following :

1. node's configured right: this is the right on the adaptation node that is set or inherited via Manager tool;
2. node's access rule: this is the right that is computed by access rule attached to the node – as set by this method
3. node's instance access rule: this is the right that is computed by the access rule attached to the instance that contains the node – see setAccessRuleOnInstance(AccessRule);
4. node's occurrence access rule: this is the right that is computed by the access rule attached to the occurrence that contains the node (if the node is in a table) – see setAccessRuleOnOccurrence(Path, AccessRule).

When a rule is not defined at some level, it is considered as AccessRule.ALWAYS_READ_WRITE.

Parameters:

aPath - location of the node

aRule - specifies the rule to assign

setAccessRuleOnNodeAndAllDescendants

public void setAccessRuleOnNodeAndAllDescendants(Path subTreePath,
                                                 boolean includeSubTreeRoot,
                                                 AccessRule aRule)

Declares that the access to a nodes subtree may be restricted by the rule specified.

Parameters:

subTreePath - specifies the root of the nodes to assign

includeSubTreeRoot - specifies whether the root is also assigned with the rule

aRule - specifies the rule to assign

setAccessRuleOnNode(Path, AccessRule)

setAccessRuleOnOccurrence

public void setAccessRuleOnOccurrence(Path aTablePath,
                                      AccessRule aRule)

Declares that the global access to a table occurrence of the schema may be restricted by the rule specified.

At runtime, the actual access permission to a table occurrence is the minimal permission of the following :

1. table's instance access rule: this is the right that is computed by the access rule attached to the instance that contains the table – see setAccessRuleOnInstance(AccessRule);
2. node's occurrence access rule: this is the right that is computed by the access rule attached to the occurrence that contains the node – as set by this method.

When a rule is not defined at some level, it is considered as AccessRule.ALWAYS_READ_WRITE.

Parameters:

aTablePath - location of table node

aRule - specifies the rule to assign
