                         Field field)

Method Detail

getField

public Field getField()

getParameter

public Parameter getParameter()

getType

public Class<T> getType()

Description copied from interface: ModuleItem

Gets the type of the item.

getGenericType

public Type getGenericType()

Description copied from interface: ModuleItem

Gets the type of the item, including Java generic parameters.

For many modules, this may be the same Class object returned by ModuleItem.getType(), but some module inputs or outputs may be backed by a generic type such as List<String> or Iterable<Integer>.

Specified by:

getGenericType in interface ModuleItem<T>

Overrides:

getGenericType in class AbstractModuleItem<T>

Field.getGenericType()

getIOType

public ItemIO getIOType()

Description copied from interface: ModuleItem

Gets the input/output type of the item.

Specified by:

getIOType in interface ModuleItem<T>

Overrides:

getIOType in class AbstractModuleItem<T>

getVisibility

public ItemVisibility getVisibility()

Description copied from interface: ModuleItem

Gets the visibility of the item.

Specified by:

getVisibility in interface ModuleItem<T>

Overrides:

getVisibility in class AbstractModuleItem<T>

isAutoFill

public boolean isAutoFill()

Description copied from interface: ModuleItem

Gets whether the item value is allowed to be auto-filled.

Specified by:

isAutoFill in interface ModuleItem<T>

Overrides:

isAutoFill in class AbstractModuleItem<T>

isRequired

public boolean isRequired()

Description copied from interface: ModuleItem

Gets whether the item value must be specified (i.e., no default).

Specified by:

isRequired in interface ModuleItem<T>

Overrides:

isPersisted

public boolean isPersisted()

Description copied from interface: ModuleItem

Gets whether to remember the most recent value of the parameter.

Specified by:
