ProjectedGetNodeCommand

public ProjectedGetNodeCommand(GetNodeCommand delegate,
                               Path projectedPath)

Method Detail

addChild

public void addChild(Path.Segment nameOfChild,
                     Property... identityProperties)

Add the child to this node. This method does not affect existing children, so callers of this method should not add a child with the same segment as an existing child (this is not checked by this method).

Specified by:

addChild in interface GetChildrenCommand

Parameters:

nameOfChild - the name of the child; should not be the same as an existing child (not checked)

identityProperties - the property/properties that are considered identity properties (other than the name) for the child

See Also:

GetChildrenCommand.addChild(org.jboss.dna.graph.properties.Path.Segment, org.jboss.dna.graph.properties.Property[])

setNoChildren

public void setNoChildren()

Set that this node has no children. Any existing child references already set on this command will be removed.

Specified by:

setNoChildren in interface GetChildrenCommand

See Also:

GetChildrenCommand.setNoChildren()

getCachePolicy

public CachePolicy getCachePolicy()

Get the caching policy to be used for this object.

Note that the values of the policy are relative to the time the node was loaded, so the same instance can be used for many nodes.

Specified by:

getCachePolicy in interface Cacheable

Returns:

cachePolicy the caching policy, which may not be null

See Also:

Cacheable.getCachePolicy()

getTimeLoaded

public DateTime getTimeLoaded()

Get the time that this node data was originally loaded.

Specified by:

getTimeLoaded in interface Cacheable

Returns:

the system time (in milliseconds) that the node data was loaded

See Also:

Cacheable.getTimeLoaded()

setCachePolicy

public void setCachePolicy(CachePolicy cachePolicy)

Set the caching policy for this object.

Specified by:

setCachePolicy in interface Cacheable

Parameters:

cachePolicy - the caching policy to use for this object

See Also:

Cacheable.setCachePolicy(org.jboss.dna.graph.cache.CachePolicy)

setProperty

public void setProperty(Property property)

Set the values for the named property. Any existing property values, if previously set, will be overwritten. If there are no property vlaues or if all of the property values are null, the property will be removed.

Specified by:

setProperty in interface GetPropertiesCommand

Parameters:

property - the property

See Also:

GetPropertiesCommand.setProperty(org.jboss.dna.graph.properties.Property)
