:: com :: sun :: star :: util ::
interface XStringSubstitution
Description A common interface for substituting string variables with other strings. The substitution algorithm and the syntax for a string variable are not part of this interface definition. Please look at the documentation of the implementation that must specify these parameters. Since OOo 1.1.2

Methods' Summary
substituteVariables | Exchanges variables inside a given text with a substitution text defined for the variables.
reSubstituteVariables | Tries to replace parts of aText with variables that represents these sub strings.
getSubstituteVariableValue | Returns the current value of a variable.

Methods' Details
substituteVariables
string
substituteVariables( | [in] string | aText,
| [in] boolean | bSubstRequired )
raises( | ::com::sun::star::container::NoSuchElementException );
Description Exchanges variables inside a given text with a substitution text defined for the variables. The method iterates through it's internal variables list to match the variables in the given string. A match replaces the variable with the string defined for this variable. If no variable can be found in the string it will be returned unchanged. The behavior if a variable is found in the string but it is unknown for the implementation depends on the parameter bSubstRequired. Parameter aText A string containing variables that should be substituted. Parameter bSubstRequired Specifies if a successful substitution is required. The function throws a ::com::sun::star::container::NoSuchElementException if it finds a variable that is unknown. In this case it is possible that the returned string would not be what the caller expected! Returns Returns a string based on aText where all variables were exchanged with their value defined at calling time.
reSubstituteVariables
string
reSubstituteVariables( | [in] string | aText );
Description Tries to replace parts of aText with variables that represents these sub strings. The method iterates through it's internal variable list and tries to match parts of the given string Tries to replace parts of aText with variables that represents these sub strings.If more than one variable matches the one with the longest matching sub string will be chosen. Parameter aText A string where known substrings should be replaced by variables. Returns Returns the resubstituted string with variables for all parts that could be replaced. The unchanged argument will be returned if nothing can be resubstituted.
getSubstituteVariableValue
string
getSubstituteVariableValue( | [in] string | variable )
raises( | ::com::sun::star::container::NoSuchElementException );
Description Returns the current value of a variable. The method iterates through it's internal variable list and tries to find the given variable. If the variable is unknown a ::com::sun::star::container::NoSuchElementException is thrown. Parameter variable The name of a variable. Returns Returns a string that represents the variable. If the variable is unknown a ::com::sun::star::container::NoSuchElementException is thrown.
