Method Details

withAssignmentDisabled

public SimpleEvaluationContext.Builder withAssignmentDisabled()

Disable assignment within expressions evaluated by this evaluation context.

Since:

5.3.38

• SimpleEvaluationContext.isAssignmentEnabled()

withIndexAccessors

public SimpleEvaluationContext.Builder withIndexAccessors(IndexAccessor... indexAccessors)

Register the specified IndexAccessor delegates.

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(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.

See Also:

• withMethodResolvers(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.

See Also:

• withTypeConverter(TypeConverter)
• StandardTypeConverter(ConversionService)

withTypeConverter

public SimpleEvaluationContext.Builder withTypeConverter(TypeConverter converter)

Register a custom TypeConverter.

By default a StandardTypeConverter backed by a DefaultConversionService is used.

See Also:

• withConversionService(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.
