Method Detail

clear

public void clear()

Clear the scanned references. This is done when we created all references and do not need to remember what to scan.

values

public Queue<Reference> values(ReferenceType referenceType)

Get the values for a certain type

Parameters:

referenceType - the type

Returns:

the references

createReferenceForOperationField

public Reference createReferenceForOperationField(org.jboss.jandex.Type fieldType,
                                                  Annotations annotationsForMethod)

Get a reference to a field type for an operation Direction is OUT on a field (and IN on an argument) In the case of operations, there is no fields (only methods)

Parameters:

fieldType - the java type

annotationsForMethod - annotation on this operations method

Returns:

a reference to the type

createReferenceForOperationArgument

public Reference createReferenceForOperationArgument(org.jboss.jandex.Type argumentType,
                                                     Annotations annotationsForThisArgument)

Get a reference to a argument type for an operation Direction is IN on an argument (and OUT on a field) In the case of operation, there is no field (only methods)

Parameters:

argumentType - the java type

annotationsForThisArgument - annotations on this argument

Returns:

a reference to the argument

createReferenceForSourceArgument

public Reference createReferenceForSourceArgument(org.jboss.jandex.Type argumentType,
                                                  Annotations annotationsForThisArgument)

Get a reference to a source argument type for an operation Direction is OUT on an argument.

Parameters:

argumentType - the java type

annotationsForThisArgument - annotations on this argument

Returns:

a reference to the argument

createReferenceForInterfaceField

public Reference createReferenceForInterfaceField(org.jboss.jandex.Type methodType,
                                                  Annotations annotationsForThisMethod,
                                                  Reference parentObjectReference)

Get a reference to a field (method response) on an interface Interfaces is only usable on Type, so the direction in OUT.

Parameters:

methodType - the method response type

annotationsForThisMethod - annotations on this method

Returns:

a reference to the type

createReferenceForPojoField

public Reference createReferenceForPojoField(Direction direction,
                                             org.jboss.jandex.Type fieldType,
                                             org.jboss.jandex.Type methodType,
                                             Annotations annotations,
                                             Reference parentObjectReference)

Get a reference to a Field Type for a InputType or Type. We need both the type and the getter/setter method as both is applicable.

Parameters:

direction - in or out

fieldType - the field type

methodType - the method type

annotations - the annotations on the field and method

parentObjectReference - Reference of the parent PoJo use so we can evaluate generics types

Returns:

a reference to the type

createReference

public Reference createReference(Direction direction,
                                 org.jboss.jandex.ClassInfo classInfo)

This method create a reference to type that might not yet exist. It also store to be created later, if we do not already know about it.

Parameters:

direction - the direction (in or out)

classInfo - the Java class

Returns:

a reference

createReference

public Reference createReference(Direction direction,
                                 org.jboss.jandex.ClassInfo classInfo,

                                 List<org.jboss.jandex.Type> parametrizedTypeArguments)

This method create a reference to type that might not yet exist. It also store to be created later, if we do not already know about it.

Parameters:

direction - the direction (in or out)
