Method Details

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

getScript

public ExecutableScript getScript()

setScript

public void setScript(ExecutableScript script)
