Data type CatalogAccessor

Value range of the data type CatalogAccessor

The input component FS_CATALOG allows section or link lists to be created and maintained.
If accessed via the API, it returns a Catalog object; in template set and snippet definitions for templates, on the other hand, a CatalogAccessor object type is returned.
The data type CatalogAccessor uses the same methods as the data type Catalog and also provides the method getSnippets, which can be used to access snippets of entries in an FS_CATALOG component.

For further information on the data type CatalogAccessor, see the API documentation:

de.espirit.firstspirit.client.access.editor.lists.CatalogAccessor

Methods for CatalogAccessor objects

The table below lists all the methods that can be called for objects of the CatalogAccessor data type:

add(Object)

Overview

addAll(Collection)

Overview

clear

Overview

contains(Object)

Overview

containsAll(Collection)

Overview

copy

Overview

create(Template, FormData)

Overview

distinct(Lambda)

This method filters a collection and returns only the first occurrence relating to a lambda expression.

It can be used to eliminate or ignore duplicates of a list according to a given condition. For this reason, it can be used for glossaries or summaries, which can then serve linked, for example, as navigational element.

See page Mapping expressions (lambda).

Overview

equals(Object)

Overview

filter(String)

Overview

filter(Lambda)

If lists have several attributes per element (comparable with a dataset with several columns), the elements can be filtered by the individual attributes using the method .filter(Lambda).

See page Mapping expressions (lambda).

Overview

find(UUID)

This method can be used to identify a "Card" by means of its UUID (java.util.UUID).

The UUID of an FS_CATALOG entry can be determined using the getId() method.

Overview

find(String)

This method can be used to identify a "Card". It returns java.util.Optional<Card>, which contains the "Card" object (if available).

The text (content of the st_text input component) of a particular entry (in this case the FS_CATALOG entry with the ID 7644cfe2-b117-4ec7-bc94-bb8f255d1f59) can be output with the following example syntax:

$CMS_VALUE(st_catalog.find("7644cfe2-b117-4ec7-bc94-bb8f255d1f59").get().item.st_text)$

The UUID of an FS_CATALOG entry can be determined using the getId() method.

Overview

fold(Lambda, Map)

This method folds the collection with the given lambda expression and start value.

See page Mapping expressions (lambda).

Overview

forEach(Consumer)

Overview

getClass

The .getClass() (in Bean syntax: .class) method returns the class of the invoking object (cf. java.lang.Class).

Invocation:

$CMS_VALUE(myString.class)$
$CMS_VALUE(myString.getClass())$

Output:

java.lang.String

Overview

getItems

The getItems method (in Bean syntax: .items) can be used to access Card data directly and work with this data. It returns a list of FormData objects:

IDENTIFIER.items

Here, IDENTIFIER is the variable name for the respective FS_CATALOG input component.

In order to be able to identify and output the value of a certain input component ("FormField") in this list for a snippet definition both the identifier of the required input component and its position in the list must be specified:

st_catalog.items[0].st_text

In this example, the value of "st_text" of the first entry in the FS_CATALOG component is identified with the "st_catalog" identifier.

Overview

getSnippets

Using this method (in Bean syntax: .snippets), the snippets of the entries in an FS_CATALOG component can be accessed, e.g.

FS_CATALOG.snippets

The method returns a list. The required element in the list can be returned by indicating the position number (in square brackets; counting starts at 0).
To access the values of the snippets for the various entries in an FS_CATALOG component, the following syntax can be used:

FS_CATALOG_VAR.snippets[0].thumbnail
FS_CATALOG_VAR.snippets[0].header
FS_CATALOG_VAR.snippets[0].extract

In this case

• thumbnail outputs the value of the Thumbnail field
• header outputs the value of the Label field
• extract outputs the value of the Extract field

The snippet definition of, in this case, the first entry in the FS_CATALOG component.
See also Interface DataSnippet (Package de.espirit.firstspirit.agency).

The image is output (field Thumbnail view) using the following example syntax:

<img src="$CMS_REF(FS_CATALOG_VAR.snippets[0].thumbnail.source)$"/>

Using $CMS_SWITCH(...)$ enables the output to be dependent on the type of image object, e.g.

$CMS_SWITCH(FS_CATALOG_VAR.snippets[0].thumbnail.source)$ 
           $CMS_CASE(class("de.espirit.firstspirit.access.store.mediastore.Media"))$ 
             thumbnail: <img src="$CMS_REF(FS_CATALOG_VAR.snippets[0].thumbnail.source)$"/> 
          
           $CMS_CASE(class("java.lang.String"))$ 
             thumbnail: $CMS_VALUE(FS_CATALOG_VAR.snippets[0].thumbnail.source)$
$CMS_END_SWITCH$

In this example, the output depends on whether the object is a media object (class de.espirit.firstspirit.access.store.mediastore.Media) or a string object (class java.lang.String).

Overview

isCase(Object)

Overview

isEmpty

The .isEmpty() (in Bean syntax: .isEmpty) method checks whether an expression or object is empty, e.g. storeElement.isEmpty(). The result of the semantic check depends on the expression or object, e.g. a character string is empty if it does not contain any characters. In the case of objects with complex values or objects, the object decides when it is empty. The data type DomElement for example always contains an empty document, thus it is never null. For this reason, checking an empty DOM editor input component by using the method .isNull()returns the value false, whereas checking the component with .isEmpty() would return the value true.

The method .isEmpty() returns a Boolean value as the check result. true is the check result if the expression or object is empty and false if not.

Overview

isNull

The .isNull() (in Bean syntax: .isNull) method checks whether an expression or object is null , e.g. storeElement.isNull(). In the case of objects with complex values or objects, the object decides when it is null. The data type DomElement for example always contains an empty document, thus it is never null. For this reason, checking an empty DOM editor input component by using the method .isNull() returns the value false, whereas checking the component with .isEmpty() would return the value true.

The method .isNull() returns a Boolean value as the check result. true is the check result if the expression or object is null and false if not.
