getCategoryName

public String getCategoryName()

Specified by:

getCategoryName in interface org.mule.runtime.api.metadata.resolving.NamedTypeResolver

getKeys

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

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

Specified by:

getKeys in interface org.mule.runtime.api.metadata.resolving.TypeKeysResolver

Parameters:

context - MetadataContext of the MetaData resolution

Returns:

Collections.emptyList()

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException

getInputMetadata

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

Null implementation of InputTypeResolver, used when no implementation is provided by the connector developer. Represents the absence of a custom InputTypeResolver, returning a VoidType instead of resolving a valid MetadataType

Specified by:

getInputMetadata in interface org.mule.runtime.api.metadata.resolving.InputTypeResolver<Object>

Parameters:

context - MetadataContext of the MetaData resolution

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

Returns:

a VoidType

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException

getOutputType

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

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

Specified by:

getOutputType in interface org.mule.runtime.api.metadata.resolving.OutputTypeResolver<Object>

Parameters:

context - MetadataContext of the MetaData resolution

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

Returns:

a VoidType

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException

getAttributesType

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

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

Specified by:

getAttributesType in interface org.mule.runtime.api.metadata.resolving.AttributesTypeResolver<Object>

Parameters:

context - MetadataContext of the MetaData resolution

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

Returns:

a VoidType

Throws:

org.mule.runtime.api.metadata.MetadataResolvingException
