Methods Summary
public static CmpFieldMapping	findCmpFieldMapping(EntityMapping em, java.lang.String fname, boolean addEmpty) Find the CmpFieldMapping element with a matching field-name element value return The CmpFieldMapping element or null if addEmpty is false and the field is not found. param em the root of the search param fname the value of the field-name element param addEmpty flag to add an empty version of the CmpFieldMapping element to the graph if one is not found. throws IllegalArgumentException If there is more than one cmp-field with a matching field-name element in the EntityMapping graph. CmpFieldMapping retVal = (CmpFieldMapping) findSingleCompatibleBean( "em", em, "fname", fname, "field-name", CmpFieldMapping.class); // NOI18N if ((null == retVal) && addEmpty) { retVal = new CmpFieldMapping(); retVal.setFieldName(fname); em.addCmpFieldMapping(retVal); } return retVal;
public static CmrFieldMapping	findCmrFieldMapping(EntityMapping em, java.lang.String fname, boolean addEmpty) Find the cmr-field-mapping element for a field in an EntityMapping object return the CmrFieldMapping element or null if addEmpty is false and the field is not found. param em The root of the search param fname the name of the field param addEmpty flag to add an empty version of the CmrFieldMapping element to the graph if one is not found. throws IllegalArgumentException If there is more than one cmr-field with a matching cmr-field-name element in the EntityMapping graph. CmrFieldMapping retVal = (CmrFieldMapping) findSingleCompatibleBean( "em", em, "fname", fname, "cmr-field-name", CmrFieldMapping.class); // NOI18N if ((null == retVal) && addEmpty) { retVal = new CmrFieldMapping(); retVal.setCmrFieldName(fname); em.addCmrFieldMapping(retVal); } return retVal;
protected static java.util.List	findCompatibleBeansWithValue(org.netbeans.modules.schema2beans.BaseBean root, java.lang.String propName, java.lang.String propVal, java.lang.Class type) A utility for finding beans in a graph of BaseBean objects. Search the bean graph, starting at a given root, for beans where the named property has the given value. The returned list is filtered by assignment compatibility. return The assignment compatible BaseBeans that were found. param root The root of a search param propName The name of the element param propVal the value of the element param type The expected type of the value to be returned. throws IllegalArgumentException If the bean is not part of a complete bean graph. List retVal = null; GraphManager gm = root.graphManager(); if (null == gm) throw new IllegalArgumentException( bundle.getString("ERR_DISCONNECTED_NOT_SUPPORTED")); String[] props = root.findPropertyValue(propName, propVal); int len = 0; if (null != props) len = props.length; if (len > 0) retVal = new ArrayList(); for (int i = 0; i < len; i++) { // get the bean that is the property's parent. BaseBean candidate = gm.getPropertyParent(props[i]); if (type.isInstance(candidate)) retVal.add(candidate); } return retVal;
public static EntityMapping	findEntityMapping(SunCmpMappings scms, java.lang.String bname, boolean addEmpty) Find the EntityMapping element that correspond to a bean. return the EntityMapping element, or null if addEmpty is false and the EntityMapping is not found. param scms the root of the SunCmpMappings graph param bname The value of the ejb-name element for a bean in the graph param addEmpty flag to add an empty version of the EntityMapping element to the graph if one is not found. throws IllegalArgumentException if more than one EntityMapping element has an ejb-name element with the matching value EntityMapping retVal = (EntityMapping) findSingleCompatibleBean( "scms", scms, "bname", bname, "ejb-name", EntityMapping.class); // NOI18N if ((null == retVal) && addEmpty) { retVal = new EntityMapping(); retVal.setEjbName(bname); SunCmpMapping scm = getFirstSunCmpMapping(scms, addEmpty); scm.addEntityMapping(retVal); } return retVal;

public static SunCmpMapping	getFirstSunCmpMapping(SunCmpMappings scms, boolean addEmpty) Return the first SunCmpMapping element from the graph. param scms The root of a SunCmpMappings object graph param addEmpty flag to add an empty version of the SunCmpMapping element to the graph if one is not found. return The first SunCmpMapping element in the graph or null if it doesn't exists and addEmpty is false. SunCmpMapping retVal = null; if (0 < scms.sizeSunCmpMapping()) retVal = scms.getSunCmpMapping(0); if ((null == retVal) && addEmpty) { retVal = new SunCmpMapping(); scms.addSunCmpMapping(retVal); } return retVal;
