Interface ExpressionLanguageMetadataService

All Known Implementing Classes:

WeaveExpressionLanguageMetadataService

public interface ExpressionLanguageMetadataService

Simplified version of Mule's ExpressionLanguageMetadataService to allow Metadata type resolvers to infer or resolve types based on already defined metadata type and Data Weave expressions.

Since:

1.0

Method Summary

Modifier and Type	Method and Description
org.mule.metadata.api.model.MetadataType	getOutputType(org.mule.metadata.api.model.MetadataType type, String expression) Given the MetadataType and a DataWeave expression it will infer the resulting output type.
org.mule.metadata.api.model.MetadataType	getOutputType(org.mule.metadata.message.api.el.TypeBindings typeBindings, String expression) Given the TypeBindings and a DataWeave expression it will infer the resulting output type.

Method Detail

getOutputType

org.mule.metadata.api.model.MetadataType getOutputType(org.mule.metadata.api.model.MetadataType type,
                                                       String expression)

Given the MetadataType and a DataWeave expression it will infer the resulting output type. The expression will be invoked with a type binding by the name payload to access the type.

Parameters:

type - the MetadataType.

expression - an expression.

Returns:

the resolving output type after applying the DataWeave expression.

getOutputType

org.mule.metadata.api.model.MetadataType getOutputType(org.mule.metadata.message.api.el.TypeBindings typeBindings,
                                                       String expression)

Given the TypeBindings and a DataWeave expression it will infer the resulting output type.

Parameters:

typeBindings - the TypeBindings.

expression - an expression.

Returns:

the resolving output type after applying the DataWeave expression.
