Method Detail

getAttribute

public Object getAttribute(Object key)

Description copied from interface: IAttributeSupport

Get an attribute value from the context

Specified by:

getAttribute in interface IAttributeSupport

Parameters:

key - the name of the attribute to get

Returns:

The value of the attribute key

getExtensions

public IExtension[] getExtensions()

Description copied from interface: IExtensionPoint

All IExtensions provided so far. The returned array does not reflect the internal structure, so you are safe to change without side effects. The returned array is always in the same order, this means especially that a new IExtension object is added to the end of the array. When there are no extensions defined, this method returns an empty array.

Specified by:

getExtensions in interface IExtensionPoint

Returns:

All IExtensions provided so far.

getId

public String getId()

Description copied from interface: IExtensionPoint

The unique id for the IExtensionPoint.

Specified by:

getId in interface IExtensionPoint

Returns:

The unique id for the IExtensionPoint.

getInstaller

public IExtensionPointHandler getInstaller()

Description copied from interface: IExtensionPoint

An optional functor object that can handle the installation semantics of the IExtensionPoint. If declared, the IExtensionPointHandler is executed immediately after the registration of the IExtensionPoint. This means that IExtension declarations to the IExtensionPoint will arrive AFTER the installation, take care to handle IExtensionPoint event notification if necessary.

Specified by:

getInstaller in interface IExtensionPoint

Returns:

An optional functor object that can handle the installation semantics of the IExtensionPoint.

getProvider

public IInstrument getProvider()

Description copied from interface: IExtensionPoint

The object providing the IExtensionPoint. This object defines the syntax and semantics associated with the IExtensionPoint.

Specified by:

getProvider in interface IExtensionPoint

Returns:

The object providing the IExtensionPoint

removeAttribute

public Object removeAttribute(Object key)

Description copied from interface: IAttributeSupport

Remove an attribute binding in the context

Specified by:

removeAttribute in interface IAttributeSupport

Parameters:

key - the name of the attribute to remove

Returns:

The previously associated value for key

setAttribute

public Object setAttribute(Object key,
                  Object value)

Description copied from interface: IAttributeSupport

Set the value of an attribute in the context

Specified by:

setAttribute in interface IAttributeSupport

Parameters:

key - the name of the attribute to set

value - the new value the attribute
