Method Detail

getWithFallback

public static String getWithFallback(com.fatwire.assetapi.data.AssetData assetData,
                                     String... orderedAttributeNames)

Get the specified attribute field from the AssetData object. If it is not found, get the next field listed. Continue until the end of the list. Safe to use with a single value. If no data is found for any attribute, an exception is thrown.

Parameters:

assetData - populated AssetData object

orderedAttributeNames - vararg array of attribute names that are expected to be found and populated in the assetData object

Returns:

the value, never null

getMultivaluedAsCommaSepString

public static String getMultivaluedAsCommaSepString(com.fatwire.assetapi.data.AttributeData attributeData)

Get the specified attribute data, converting each of the values into a string and separating them with a comma (no space).

Parameters:

attributeData - multi-valued attribute data

Returns:

attribute data converted to a string, comma-separated.

getAndSplitString

public static Collection<String> getAndSplitString(com.fatwire.assetapi.data.AttributeData attributeData,
                                                   String delimRegex)

Get an attribute that is a comma-separated string and split it into a collection. If the attribute has no values, an empty list is returned. All attribute values or substring values of zero length are dropped.

Parameters:

attributeData -

delimRegex - regex for splitting

Returns:

Collection of attribute data, never null (though an empty list may be returned
