Method Detail

isAbstract

public boolean isAbstract()

Description copied from interface: Type

Indicates if this Type is abstract. If true, this Type cannot be instantiated. Abstract types cannot be used in DataObject or DataFactory create methods.

Specified by:

isAbstract in interface Type

Overrides:

isAbstract in class SDOType

Returns:

true if this Type is abstract.

isDataType

public boolean isDataType()

Description copied from interface: Type

Indicates if this Type specifies DataTypes (true) or DataObjects (false). When false, any object that is an instance of this type also implements the DataObject interface. True for simple types such as Strings and numbers. For any object:

   isInstance(object) && !isDataType() implies
   DataObject.class.isInstance(object) returns true. 
 

Specified by:

isDataType in interface Type

Overrides:

isDataType in class SDOType

Returns:

true if Type specifies DataTypes, false for DataObjects.

isInstance

public boolean isInstance(Object object)

Description copied from interface: Type

Returns whether the specified object is an instance of this type.

Specified by:

isInstance in interface Type

Overrides:

isInstance in class SDOType

Parameters:

object - the object in question.

Returns:

true if the object is an instance.

See Also:

Class.isInstance(java.lang.Object)

isOpen

public boolean isOpen()

Description copied from interface: Type

Indicates if this Type allows any form of open content. If false, dataObject.getInstanceProperties() must be the same as dataObject.getType().getProperties() for any DataObject dataObject of this Type.

Specified by:

isOpen in interface Type

Overrides:

isOpen in class SDOType

Returns:

true if this Type allows open content.

isSequenced

public boolean isSequenced()

Description copied from interface: Type

Indicates if this Type specifies Sequenced DataObjects. Sequenced DataObjects are used when the order of values between Properties must be preserved. When true, a DataObject will return a Sequence. For example,

  Sequence elements = dataObject.getSequence();
 

Specified by:

isSequenced in interface Type

Overrides:

isSequenced in class SDOType

Returns:

true if this Type specifies Sequenced DataObjects.

getPseudoDefault

public Object getPseudoDefault()

Description copied from class: SDOType

INTERNAL: Return the wrapped initial value for the primitive numeric (when not defined) See p.45 of Java Spec 4th edition. See p.85 Sect 9.3 of the SDO Spec.

Overrides:

getPseudoDefault in class SDOType

Returns:

aDefault Object (primitive numerics) or null (DataObjects, String, Lists)

addOpenMappings

protected void addOpenMappings()

setOpen

public void setOpen(boolean bOpen)

Description copied from class: SDOType

INTERNAL: Make this Type an opened Type to allow open content by assigning true value or a Type not to accept any additional properties by assigning false value, SDOType.isOpen().

Overrides:

setOpen in class SDOType

Parameters:

bOpen - boolean value implying if this Type is open
