Interface HippoNode

All Superinterfaces:

Item, Node

public interface HippoNode
extends Node

Any Node instance returned by any method of a Hippo Repostitory may be cast to the HippoNode interface to expose additional functionality.

Method Detail

getDisplayName

String getDisplayName()
               throws RepositoryException

Obtain a display name for this node. If not available falls back on Item.getName(). If display name is available the result is the same as calling getProperty("hippo:name").getString(). If this node does not have a display name but is a child node of a hippo:handle node having a display name, the display name of the parent handle node will be returned.

Returns:

the display name for this node if available, otherwise the JCR name of this node.

Throws:

RepositoryException

getCanonicalNode

Node getCanonicalNode()
               throws ItemNotFoundException,
                      RepositoryException

Get the most accurate and complete version available of the information represented in the current node. Certain operations are only allowed on the most complete version of a node, rather than on any presentation of the node.

Returns:

the node with the most accurate representation of this node, may be nonsense if there is no sensible canonical version available

Throws:

ItemNotFoundException - indicates the canonical node is no longer available

RepositoryException - indicates a generic unspecified repository error

pendingChanges

NodeIterator pendingChanges(String nodeType,
                            boolean prune)
                     throws NamespaceException,
                            NoSuchNodeTypeException,
                            RepositoryException

Obtains an iterator over the set of nodes that potentially contain changes, starting (and not including) this node. Only nodes for which Node.isNodeType(nodeType) returns true are included in the resulting set. If the prune boolean value is true, then the nodes matching in the hierarchy first are returned. If matching modified node exists beneath the nodes, these are not included.

Parameters:

nodeType - Only nodes that are (derived) of this nodeType are included in the result

prune - Whether only to return the first matching modified node in a subtree (true), or provide a depth search for all modified nodes (false)

Returns:

A NodeIterator instance which iterates over all modified nodes, not including this node

Throws:

NamespaceException - indicates an invalid nodeType parameter

NoSuchNodeTypeException - indicates an invalid nodeType parameter

RepositoryException - indicates a generic unspecified repository error

HippoSession.pendingChanges(Node,String,boolean)

pendingChanges

NodeIterator pendingChanges(String nodeType)
                     throws NamespaceException,
                            NoSuchNodeTypeException,
                            RepositoryException

Conveniance method for pendingChanges(nodeType,false)

Parameters:

nodeType - Only nodes that are (derived) of this nodeType are included in the result

Returns:

A NodeIterator instance which iterates over all modified nodes, not including the passed node

Throws:

NamespaceException - indicates an invalid nodeType parameter

RepositoryException - indicates a generic unspecified repository error

NoSuchNodeTypeException - indicates an invalid nodeType parameter

See Also:

pendingChanges(String,boolean)

pendingChanges

NodeIterator pendingChanges()
                     throws RepositoryException

Conveniance method for pendingChanges("nt:base", false)

Returns:

A NodeIterator instance which iterates over all modified nodes, not including the passed node

Throws:

RepositoryException - indicates a generic unspecified repository error

See Also:

pendingChanges(String,boolean)

isVirtual

boolean isVirtual()
           throws RepositoryException

Whether this is a virtual node or not.

Returns:

whether this is a virtual node or not.

Throws:

RepositoryException

recomputeDerivedData

boolean recomputeDerivedData()
                      throws RepositoryException

Some operations may leave some nodes' derived data stale. With this method the derived data of a node is made up to date.

Returns:

whether the node was changed during the recomputation

Throws:

RepositoryException
