Constructor Detail

FromContext

protected FromContext(String fromString)

Create a new state

Parameters:

fromString - the string representation

Method Detail

getInstance

public static FromContext getInstance(String fromString)

Return from type.

executeLookup

public Object executeLookup(org.jboss.dependency.spi.ControllerContext context)
                     throws Throwable

Execute injection on context.

Parameters:

context - the target context

Returns:

lookup value

Throws:

Throwable - for any error

internalExecute

public abstract Object internalExecute(T context)
                                throws Throwable

Execute internal lookup on context.

Parameters:

context - the target context

Returns:

lookup value

Throws:

Throwable - for any error

getFromString

public String getFromString()

Get the from string

Returns:

the state string
