Method Details

getEvaluationContext

public ValueEvaluationContext getEvaluationContext(@Nullable
 Object rootObject)

Description copied from interface: ValueEvaluationContextProvider

Return a EvaluationContext built using the given parameter values.

Specified by:

getEvaluationContext in interface ValueEvaluationContextProvider

Parameters:

rootObject - the root object to set in the EvaluationContext.

Returns:

getEvaluationContext

public ValueEvaluationContext getEvaluationContext(@Nullable
 Object rootObject,
 ExpressionDependencies dependencies)

Description copied from interface: ValueEvaluationContextProvider

Return a tailored EvaluationContext built using the given parameter values and considering expression dependencies. The returned EvaluationContext may contain a reduced visibility of methods and properties/fields according to the required expression dependencies.

dependencies - the requested expression dependencies to be available.

Returns:

create

public ValueExpressionEvaluator create(Object source)

Creates a new ValueExpressionEvaluator using the given source as root object.

Parameters:

source - the root object for evaluating the expression.

Returns:

a new ValueExpressionEvaluator to evaluate the expression in the context of the given source object.
