Method Summary

Long	getDbid() the db primary key.
String	getName() the name of this descriptor
Class<?>	getType(WireDefinition wireDefinition) the type of the produced object or null if that is not available
void	initialize(Object object, WireContext wireContext) called by the WireContext to initialize the specified object.
boolean	isDelayable() Checks if the initialization should be done during the construction phase or if it can be done later.
boolean	isEagerInit() if eager initialization is set, it means that an object must be created immediately during construction of the WireContext.

Method Detail

getType

public Class<?> getType(WireDefinition wireDefinition)

Description copied from interface: Descriptor

the type of the produced object or null if that is not available

Specified by:

getType in interface Descriptor

isEagerInit

public boolean isEagerInit()

Description copied from interface: Descriptor

if eager initialization is set, it means that an object must be created immediately during construction of the WireContext.

Specified by:

isEagerInit in interface Descriptor

isDelayable

public boolean isDelayable()

Description copied from interface: Descriptor

Checks if the initialization should be done during the construction phase or if it can be done later.

Specified by:

isDelayable in interface Descriptor

Returns:

false if the initialization should be done during the creation phase, true if it can be done later.

initialize

public void initialize(Object object,
                       WireContext wireContext)

Description copied from interface: Descriptor

called by the WireContext to initialize the specified object. For more information about initialization, see WireContext section lifecycle.

Specified by:

initialize in interface Descriptor

Parameters:

object - object to initialize.

wireContext - the context in which the object will be initialized.

getDbid

public Long getDbid()

the db primary key.

getName

public String getName()

Description copied from interface: Descriptor

the name of this descriptor

Specified by:

getName in interface Descriptor

setName

public void setName(String name)

setInit

public void setInit(char init)
