NAME
EPrints::Const - constants and enumerations
SYNOPSIS
# don't import any constants
use EPrints::Const qw();
# import trigger and http constants
use EPrints::Const qw( :trigger :http );
# import only the OK DONE DECLINED constants
use EPrints::Const qw( OK DONE DECLINED );
DESCRIPTION
This module contains EPrints constants and enumerations.
CONSTANTS

- EP_NS_DATA
- EP_NS_XSLT
- EP_NS_OPENSEARCH
:xml

- XML_DOCUMENT_NODE
- XML_DOCUMENT_TYPE_NODE
- XML_DOCUMENT_FRAGMENT_NODE
- XML_NOTATION_NODE
:http
- DONE
- DECLINED
- NOT_FOUND
- OK
And all HTTP_* constants defined by Apache2::Const.
:trigger
See EPrints::RepositoryConfig/add_trigger and EPrints::RepositoryConfig/add_dataset_trigger.
- EP_TRIGGER_DONE
- Stop processing triggers immediately and return.
- EP_TRIGGER_OK
- Continue normal processing.
- EP_TRIGGER_LOG
- EP_TRIGGER_BOILERPLATE_RDF
- EP_TRIGGER_REPOSITORY_RDF
- EP_TRIGGER_BEGIN
- EP_TRIGGER_BEGIN_REQUEST
- Called after EPrints::Repository/init_from_request.
- EP_TRIGGER_END_REQUEST
- Called just before EPrints::Repository/cleanup in response to a mod_perl request.
- EP_TRIGGER_END
- EP_TRIGGER_URL_REWRITE
- Called for every request that is within the repository's path. Use this to redirect the user to a different location.
return_codeis a scalar reference, therefore you must deference when assigning a new value${$rc} = CODE.
request - mod_perl request object lang - current language id args - request arguments "?..." urlpath - EPrint's HTTP root cgipath - EPrints's HTTP cgi root uri - request uri "/eprints/12/" secure - whether under HTTPS return_code - reference to return code
- EP_TRIGGER_DOC_URL_REWRITE
- EP_TRIGGER_CREATED
- Called after $dataset->create_dataobj( { ... } ).
dataobj - the newly created dataobj
- EP_TRIGGER_REMOVED
- Called just before the object is removed from the database.
dataobj - the object being removed
- EP_TRIGGER_DUPLICATE_SEARCH
- Search for duplicate entries of the given data object. Triggers must be quick and conservative i.e. only return duplicates that are very likely candidates. ids is a list of object identifiers of the duplicate records.
dataset = EPrints::DataSet dataobj = EPrints::DataObj ids = ARRAY
- EP_TRIGGER_RDF
- EP_TRIGGER_DEFAULTS
- EP_TRIGGER_STATUS_CHANGE
- EP_TRIGGER_BEFORE_COMMIT
- EP_TRIGGER_AFTER_COMMIT
- EP_TRIGGER_VALIDATE
- EP_TRIGGER_VALIDATE_FIELD
- Validate a field's value.
field - field to validate value - value to validate dataobj - parent dataobj (if available) problems - ARRAYREF of DOM problems encountered
- EP_TRIGGER_WARNINGS
- EP_TRIGGER_FILES_MODIFIED
- EP_TRIGGER_MEDIA_INFO
- Populate a Document epdata structure with information about a file.
epdata filename filepath
- EP_TRIGGER_THUMBNAIL_TYPES
- Manipulate the list of thumbnail types that will be generated for a given user-uploaded document.
types - array reference of types (strings) dataobj - document object
- EP_TRIGGER_INDEX_FIELDS
- Add the changed fields for the given data object to the index engine(s).
dataobj = EPrints::DataObj fields = ARRAYREF of field objects
- EP_TRIGGER_INDEX_REMOVED
- An object was removed and should now be removed from the index engine(s).
dataset = EPrints::DataSet id = object id
- EP_TRIGGER_DYNAMIC_TEMPLATE
- Manipulate parts included in the template. These will be called for every page impression, so don't do anything heavyweight in here.
pins - hash ref of template pins
:metafield
- EP_PROPERTY_FROM_CONFIG
- Get the default value from field defaults in the config.
- EP_PROPERTY_NO_CHANGE
- Don't use a default, the code may have already set this value. setting it to undef has no effect rather than setting it to default value.
- EP_PROPERTY_REQUIRED
- This field property must be explicitly set.
- EP_PROPERTY_UNDEF
- This field property defaults to undef.
- EP_PROPERTY_TRUE
- This field property defaults to true.
- EP_PROPERTY_FALSE
- This field property defaults to false.
:crypt
- One-way encryption methods for passwords, see EPrints::Utils/crypt.
- EP_CRYPT_CRYPT
- EP_CRYPT_SHA512
- Digest::SHA sha512 with 2-byte salt and 10000 rounds.
