getVariableValue

protected String getVariableValue(String varName)
                           throws TranslationException

Description copied from class: VariableResolver

Returns the value of the variable. This class will not try to further expand variables in the returned value. If the implementation wants to do so, that is the implementation's responsibility.

Specified by:

getVariableValue in class VariableResolver

Returns:

null if the variable is not found. The caller will report an error. When the variable is not found, it's also legal to throw TranslationException, which is an useful technique if the implementation would like to report additional errors.

Throws:

TranslationException

needsResolving

public static boolean needsResolving(String value)

Return true if the string is a template string of the for ${...}

resolve

public String resolve(String in)
               throws TranslationException
