Data type Index

The Index data type enhances the interface Collection<E>.

Elements which are obtained using the iterator are of the Record data type.

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

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

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

hashCode

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.

toString

Overview

toString(String)

The individual elements, e.g. of a list, can be output as string, separated by a delimiter which can be chosen freely.

Example:

$CMS_SET(myList, ["House","Key","Window"])$
$CMS_VALUE(myList.toString("; "))$

The elements of the list myList are output, separated each by semicolon and a space character:

House; Key; Window
