- Method Detail
  - getValue
```
public Object getValue(VariableScope variableScope)
```
    Specified by:
    
    getValue in interface ParameterValueProvider
    
    Parameters:
    
    variableScope - the scope in which the value is to be resolved.
    
    Returns:
    
    the value
  - isDynamic
```
public boolean isDynamic()
```
    Specified by:
    
    isDynamic in interface ParameterValueProvider
    
    Returns:
    
    true if the value provider:
    
    Can return a different value depending on the passed variable scope
    May uses external data for its resolution
    May have side effects
    If true, a caller of ParameterValueProvider.getValue(VariableScope) can assume that:
    
    passing an empty variable scope returns the same value as passing any other variable scope
    Calling ParameterValueProvider.getValue(VariableScope) multiple times always returns the same value
    Calling ParameterValueProvider.getValue(VariableScope) does not have side effects
