Example:
<#assign seqVal = [1, 2, 3, 4, 5] />
<#list seqVal as aVal>...</#list>
${seqVal[1]}
<#-- It is possible to browse the seqVal values or access a seqVal element but it is not easy to change a seqVal element or delete an element in seqVal -->
<#-- Inefficient solution for changing an element (element in position 2 starting from 0) -->
<#assign seqVal = seqVal[0..(2-1)] + [33] + seqVal[(2+1)..]/>
<#-- Inefficient solution for changing an element (element in position 2 starting from 0)-->
<#assign seqVal = [1, 2, 3, 4, 5] />
<#assign seqVal = seqVal[0..(2-1)] + seqVal[(2+1)..]/>
This function returns a Sequence-type object which has add/change/delete methods: this object is an encapsulation of the Java ArrayList object (click here for more details). Some methods from the ArrayList class can be used in a FreeMarker execution context: add/clear/contains/ensureCapacity/get/indexOf/isEmpty/lastIndexOf/remove/removeRange/set/size/subList/toArray.
Parameters
No parameter.
For example
<#assign newSeq = hardisCore.createArrayList() />
<#-- Use sequence built-in function with newSeq variable -->
Size of newSeq:${newSeq?size}
<#-- Use Java ArrayList "compatible" methods with newSeq variable -->
IsEmpty:${newSeq.isEmpty()}
<#assign textToAdd = "Hello"/>
<#assign addOK = newSeq.add(textToAdd) />
