Method Details

getEvaluationContext

public EvaluationContext getEvaluationContext(Object rootObject)

Description copied from interface: EvaluationContextProvider

Return a EvaluationContext built using the given parameter values.

Specified by:

getEvaluationContext in interface EvaluationContextProvider

Parameters:

rootObject - the root object to set in the EvaluationContext.

Returns:

getEvaluationContext

public EvaluationContext getEvaluationContext(Object rootObject,
 ExpressionDependencies dependencies)

Description copied from interface: EvaluationContextProvider

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.

Specified by:

getEvaluationContext in interface EvaluationContextProvider

Parameters:

rootObject - the root object to set in the EvaluationContext.

dependencies - the requested expression dependencies to be available.

Returns:

getEvaluationContextLater

public reactor.core.publisher.Mono<StandardEvaluationContext> getEvaluationContextLater(@Nullable
 Object rootObject)

Description copied from interface: ReactiveEvaluationContextProvider

Return a EvaluationContext built using the given parameter values.

Specified by:

getEvaluationContextLater in interface ReactiveEvaluationContextProvider

Parameters:

rootObject - the root object to set in the EvaluationContext.

Returns:

a mono that emits exactly one EvaluationContext.

getEvaluationContextLater

public reactor.core.publisher.Mono<StandardEvaluationContext> getEvaluationContextLater(@Nullable
 Object rootObject,
 ExpressionDependencies dependencies)

Description copied from interface: ReactiveEvaluationContextProvider

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.

Specified by:

getEvaluationContextLater in interface ReactiveEvaluationContextProvider

Parameters:

rootObject - the root object to set in the EvaluationContext.

dependencies - the requested expression dependencies to be available.

Returns:

a mono that emits exactly one EvaluationContext.
