Method Detail

getMetadataKeys

public Set<org.mule.runtime.api.metadata.MetadataKey> getMetadataKeys(org.mule.runtime.api.metadata.MetadataContext context)
                                                               throws org.mule.runtime.api.metadata.MetadataResolvingException

Null implementation of MetadataKeysResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom MetadataKeysResolver, returning an empty list of MetadataKey.

Specified by:

getMetadataKeys in interface org.mule.runtime.api.metadata.resolving.MetadataKeysResolver

Parameters:

context - MetadataContext of the MetaData resolution

Returns:

Collections.emptyList()

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException

getContentMetadata

public org.mule.metadata.api.model.MetadataType getContentMetadata(org.mule.runtime.api.metadata.MetadataContext context,
                                                                   Object key)
                                                            throws org.mule.runtime.api.metadata.MetadataResolvingException

Null implementation of MetadataContentResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom MetadataContentResolver, returning a NullType instead of resolving a valid MetadataType for the Content parameter

Specified by:

getContentMetadata in interface org.mule.runtime.api.metadata.resolving.MetadataContentResolver<Object>

Parameters:

context - MetadataContext of the MetaData resolution

key - MetadataKey of the type which's structure has to be resolved

Returns:

null

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException

getOutputMetadata

public org.mule.metadata.api.model.MetadataType getOutputMetadata(org.mule.runtime.api.metadata.MetadataContext context,
                                                                  Object key)
                                                           throws org.mule.runtime.api.metadata.MetadataResolvingException

Null implementation of MetadataOutputResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom MetadataOutputResolver, returning a NullType instead of resolving a dynamic MetadataType for the component's output.

Specified by:

getOutputMetadata in interface org.mule.runtime.api.metadata.resolving.MetadataOutputResolver<Object>

Parameters:

context - MetadataContext of the MetaData resolution

key - MetadataKey of the type which's structure has to be resolved

Returns:

null

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException

getAttributesMetadata

public org.mule.metadata.api.model.MetadataType getAttributesMetadata(org.mule.runtime.api.metadata.MetadataContext context,
                                                                      Object key)
                                                               throws org.mule.runtime.api.metadata.MetadataResolvingException

Null implementation of MetadataAttributesResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom MetadataAttributesResolver, returning a AnyType instead of resolving a dynamic MetadataType for the component's output attributes.

Specified by:

getAttributesMetadata in interface org.mule.runtime.api.metadata.resolving.MetadataAttributesResolver<Object>

Parameters:

context - MetadataContext of the MetaData resolution

key - MetadataKey of the type which's structure has to be resolved

Returns:

null

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException
