String data type

Value range of the String data type

FirstSpirit makes the data type String available for editing values which represent a fixed or variable length text. A string contains a character string consisting of a sequence of characters (e.g. letters, digits, special characters and control characters) from a defined character set. The order of the characters is defined by the character chain. All characters can be repeated within a character chain as many times as required.

The data type string can also be looked up in the Java API documentation:

java.lang.String

Definition

In FirstSpirit, when a string is defined a string object in the class java.lang.String is generated.

$CMS_SET(myString, "That is a text.")$

Definition using the standard input components

Within the form area of templates, input components are defined which can be subsequently used by the editors to insert the actual editorial contents into the page. The standard input components supported by FirstSpirit return different data types.

The following standard input components return an object of data type string:

• CMS_INPUT_TEXT
• CMS_INPUT_TEXTAREA

With the help of a $CMS_VALUE(...)$ instruction, methods can then be applied to this object:

$CMS_VALUE(IDENTIFIER.METHOD)$

compareTo(String)

The .compareTo(String) (in Bean syntax: .compareTo(String)) method returns a lexicographic comparison of two strings (cf. java.lang.String). The method returns a positive value if the string is lexicographically larger than the transferred string and a negative value if the string is lexicographically smaller. The method returns 0 if the transferred string is identical to the invoking string.

Invocation:

$CMS_SET(myString, "Das ist ein String.")$
$CMS_VALUE(myString.compareTo("Das ist ein String"))$

It is case sensitive, i.e. a differentiation is made between upper and lower case letters.

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.

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.

The .lastIndexOf(String) (in Bean syntax: .lastIndexOf(String)) method returns an index of the character string at which the first character of a sub-string is found or -1 if the transferred sub-string is not found in the character string (cf. java.lang.String). It is case sensitive, i.e. a differentiation is made between upper and lower case letters.

Unlike the .indexOf(String) method the index of the last and not the first occurrence is returned.

Invocation:

$CMS_SET(myString, "Das ist ein String.")$
$CMS_VALUE(myString.lastIndexOf("ein")$

startsWith(String)

The method checks whether a string of characters (e.g. a text) starts with a special character string, also refer to java.lang.String

The check starts with the first character. To have the check start at a different character in the text, this can be done using the startsWith(String, int) method.

This method returns a Boolean value as the result of the check. The check is true if the saved text matches the string of characters specified in the method and false if it does not.

Example:
The following example checks whether the input starts with the string "Hello". If it does not, a "Hello" is placed in front of the output.

$CMS_IF(!text.startsWith("Hello"))$
 Hello $CMS_VALUE(text)$

 $CMS_ELSE$
  $CMS_VALUE(text)$

$CMS_END_IF$

If Hello Anna is the input, then the output is not changed:

Hello Anna

If only Anna has been entered, "Hello" is added. The output is then

Hello Anna

Overview

startsWith(String, int)

This method checks whether a saved text contains a special string at a particular location, also refer to java.lang.String

The passed number (int) specifies at which character the check should proceed. The counting starts with 0; the location of the first character of the text to be checked is therefore 0, the second is 1, etc.

This method returns a Boolean value as the result of the check. The check is true if the saved text matches the string specified in the method at the specified location and false if it does not.

For instance, the following syntax can be used to check whether the second and third characters of the text input in a text input component is "al":

Are the second and third character of the entered text "al"? </br>
$CMS_IF(text.startsWith("al", 1))$
    => That's right.
$CMS_ELSE$
    => That's wrong.
$CMS_END_IF$

If the text saved in the text variable is false, "=> That's right." is output; otherwise, "=> That's wrong." is output.

Space characters are converted into plus signs.

The following encoding is used for the conversion: UTF-8.

The invocation:
