Method Detail

newExpression

public Expression newExpression()

Description copied from interface: ExpressionFactory

Creates a new expression implementation.

Specified by:

newExpression in interface ExpressionFactory

Returns:

returns a new expression implementation

setInteger2TextFactory

public void setInteger2TextFactory(Integer2TextFactoryMakerService service)

Sets a factory dependency.

Parameters:

service - the dependency

unsetInteger2TextFactory

public void unsetInteger2TextFactory(Integer2TextFactoryMakerService service)

Removes a factory dependency.

Parameters:

service - the dependency to remove

setCreatedWithSPI

public void setCreatedWithSPI()

Description copied from interface: ExpressionFactory

Informs the implementation that it was discovered and instantiated using information collected from a file within the META-INF/services directory. In other words, it was created using SPI (service provider interfaces).

This information, in turn, enables the implementation to use the same mechanism to set dependencies as needed.

If this information is not given, an implementation should avoid using SPIs and instead use declarative services for dependency injection as specified by OSGi. Note that this also applies to several newInstance() methods in the Java API.

The class that created an instance with SPI must call this method before putting it to use.

Specified by:

setCreatedWithSPI in interface ExpressionFactory
