org.pentaho.reporting.engine.classic.core.style.ElementStyleSheet
An element style-sheet contains zero, one or many attributes that affect the appearance of report elements. For each attribute, there is a predefined key that can be used to access that attribute in the style sheet.
Every report element has an associated style-sheet.
A style-sheet maintains a list of parent style-sheets. If an attribute is not defined in a style-sheet, the code refers to the parent style-sheets to see if the attribute is defined there.
All StyleSheet entries are checked against the StyleKeyDefinition for validity.
As usual, this implementation is not synchronized, we need the performance during the reporting. @author Thomas Morgner @noinspection UnnecessaryUnboxing
