addParameter

public void addParameter(EnhancementOperation op,
                         String parameterName,
                         String propertyName,

                         boolean cache,
                         org.apache.hivemind.Location location)

Adds a parameter as a (very smart) property.

Parameters:

op - the enhancement operation

parameterName - the name of the parameter (used to access the binding)

propertyName - the name of the property to create (usually, but not always, matches the parameterName)

specifiedType - the type declared in the DTD (only 3.0 DTD supports this), may be null (always null for 4.0 DTD)

cache - if true, then the value should be cached while the component renders; false (a much less common case) means that every access will work through binding object.

location - Used for reporting line-precise errors in binding resolution / setting / etc..

setErrorLog

public void setErrorLog(org.apache.hivemind.ErrorLog errorLog)
