Method Detail

canGetValue

boolean canGetValue(ScenarioExecutionContext pContext)

Deprecated.

Returns true if the expression can be resolved in the given scenario execution context, false otherwise. Thus, false is returned if the context does not yet contain all of the information necessary to evaluate the expression - for example, if the expression refers to properties of the profile, and the context is missing the particular profile that the scenario is being executed on.

It's legal to call this method with a null argument; true will be returned if the context is not required at all to evaluate the expression.

getValue

java.lang.Object getValue(ScenarioExecutionContext pContext)
                          throws ScenarioException

Deprecated.

Resolves the expression in the given scenario execution context, and returns the resulting value. For example, if the expression represents a profile property, it is resolved using the profile pointed to by the context. The context argument can be null if the value of the expression does not depend on the context.

This method should be called only if the scenario execution context is known to contain all the information necessary to resolve the expression (in other words, if Expression.canGetValue returns true).

Throws:

ScenarioException - if the expression could not be resolved
