Class BasicExpressionFunctions

java.lang.Object

com.evolveum.midpoint.model.common.expression.functions.BasicExpressionFunctions

public class BasicExpressionFunctions
extends Object

Library of standard midPoint functions. These functions are made available to all midPoint expressions.

The functions should be written to support scripting-like comfort. It means that they all needs to be null-safe, automatically convert data types as necessary and so on.

 Object search)

trim

public static String trim(String orig)

Remove whitespaces at the beginning and at the end of the string.

concatName

public String concatName(Object... components)

Concatenates the arguments to create a name. Each argument is stringified, trimmed and the result is concatenated by spaces.

startsWith

public boolean startsWith(String string,
 String value)

Checks whether the given normalized string begins with the specified value by first normalizing it.

Parameters:

string - the string

value - the value

Returns:

true/false

Checks whether the given normalized string begins with the specified value.

Parameters:

polyString - the string

value - the value

Returns:

true/false

Checks whether the given normalized string ends with the specified value by first normalizing it.

Parameters:

string - the string

value - the value

Returns:
