Examples of com.volantis.mcs.context.MetaData

com.volantis.mcs.context.MetaData
Meta data for a given element or for a whole page.
Meta data can store values against property names. Each property name can be associated with a value or with a list of values (but the two must not be mixed for a given property).

{@link #setPropertyValue(String,Object)} can be used to set the value forsingle-value properties and {@link #addPropertyValue(String,Object)} to adda value to multi-value properties.
