Method Details

withAssignmentDisabled

public SimpleEvaluationContext.Builder withAssignmentDisabled()

Disable assignment within expressions evaluated by this evaluation context.

Parameters:

indexAccessors - the index accessors to use

Since:

6.2

withMethodResolvers

public SimpleEvaluationContext.Builder withMethodResolvers(MethodResolver... resolvers)

Register the specified MethodResolver delegates for a combination of property access and method resolution.

Parameters:

resolvers - the resolver delegates to use

• withInstanceMethods()
• SimpleEvaluationContext.forPropertyAccessors(org.springframework.expression.PropertyAccessor...)

withInstanceMethods

public SimpleEvaluationContext.Builder withInstanceMethods()

Register a DataBindingMethodResolver for instance method invocation purposes (i.e. not supporting static methods) in addition to the specified property accessors, typically in combination with a DataBindingPropertyAccessor.

• withMethodResolvers(org.springframework.expression.MethodResolver...)
• SimpleEvaluationContext.forReadOnlyDataBinding()
• SimpleEvaluationContext.forReadWriteDataBinding()

withConversionService

public SimpleEvaluationContext.Builder withConversionService(ConversionService conversionService)

Register a custom ConversionService.

By default a StandardTypeConverter backed by a DefaultConversionService is used.

• withTypeConverter(org.springframework.expression.TypeConverter)
• StandardTypeConverter(ConversionService)

withTypeConverter

public SimpleEvaluationContext.Builder withTypeConverter(TypeConverter converter)

Register a custom TypeConverter.

By default a StandardTypeConverter backed by a DefaultConversionService is used.

• withConversionService(org.springframework.core.convert.ConversionService)
• StandardTypeConverter()

withRootObject

public SimpleEvaluationContext.Builder withRootObject(Object rootObject)

Specify a default root object to resolve against.

Default is none, expecting an object argument at evaluation time.

See Also:

• Expression.getValue(EvaluationContext)
• Expression.getValue(EvaluationContext, Object)

withTypedRootObject

public SimpleEvaluationContext.Builder withTypedRootObject(Object rootObject,
 TypeDescriptor typeDescriptor)

Specify a typed root object to resolve against.

Default is none, expecting an object argument at evaluation time.
