Method Detail

setRepository

public ReferenceSearch setRepository(SlingRepository repository)

Deprecated. The repository was used by the implementation to create an administrative session in adjustReferences(ResourceResolver, String, String, String[]). Instead, specify a resource resolver which is sufficiently authorized to adjust references at the desired locations.

Parameters:

repository - The repository

Returns:

this

getSearchRoot

public java.lang.String getSearchRoot()

Returns the search root. default is '/'

Returns:

the search root.

setSearchRoot

public ReferenceSearch setSearchRoot(java.lang.String searchRoot)

Sets the search root

Parameters:

searchRoot - the search root

Returns:

this

isExact

public boolean isExact()

Returns the shallow flag.

Returns:

the shallow flag.

See Also:

setExact(boolean)

setExact

public ReferenceSearch setExact(boolean exact)

Sets the exact flag. If true only exact references are searched (and replaced). otherwise also references to child resources are included.

Parameters:

exact - true if perform an exact search

Returns:

this;

isHollow

public boolean isHollow()

Returns the hollow flag.

Returns:

the hollow flag.

See Also:

setHollow(boolean)

setHollow

public ReferenceSearch setHollow(boolean hollow)

Sets the hollow flag. If true the returned info will contain only properties of the page and not the page object itself.

Parameters:

hollow - true if perform a hollow search

Returns:

this;

getMaxReferencesPerPage

public int getMaxReferencesPerPage()

Returns the maximum number of references that can be added to a page info.

Returns:

the reference limit per page.

See Also:

setMaxReferencesPerPage(int)

setMaxReferencesPerPage

public ReferenceSearch setMaxReferencesPerPage(int maxReferencesPerPage)

Sets the value of maxReferencesPerPage. The maximum number of references that can be added to a page info.

Parameters:

maxReferencesPerPage - The maximum number of references that can be added to a page info.

Returns:

this;

setPredicate

public ReferenceSearch setPredicate(AbstractResourcePredicate resourcePredicate)

Set the resourcePredicate, this predicate is evaluated for each search result and can be used to filter results.

Parameters:

resourcePredicate - an instance of AbstractResourcePredicate

Returns:

this;

search

public java.util.Map<java.lang.String,ReferenceSearch.Info> search(ResourceResolver resolver,
                                                                   java.lang.String path)

Searches for references to the given path.

Parameters:

resolver - the resource resolver

path - the path to search for

Returns:

reference infos

adjustReferences

public java.util.Collection<java.lang.String> adjustReferences(ResourceResolver resolver,
                                                               java.lang.String path,
                                                               java.lang.String destination,
                                                               java.lang.String[] refPaths)

Adjusts all references to path to destination in the pages specified by refPaths. If isExact() is true only exact references to path are adjusted, otherwise all references to child resources are adjusted, too.

The resource resolver needs to have sufficient permissions (i.e. jcr:read and rep:alterProperties) on the nodes containing references.

Parameters:

resolver - resolver to operate on.

path - source path

destination - destination path

refPaths - paths of pages to be adjusted

Returns:

collection of path to properties that were adjusted

adjustReferences

public java.util.Collection<java.lang.String> adjustReferences(Node node,
                                                               java.lang.String path,
                                                               java.lang.String destination)

Adjusts all references to path to destination in the properties below the specified node. If isExact() is true only exact references to path are adjusted, otherwise all references to child resources are adjusted, too.

node - (content) node to traverse

path - source path

destination - destination path

Returns:

collection of paths to properties that were adjusted

Throws:

RepositoryException - if an error during repository access occurs
