Method Detail

getName

public String getName()

Specified by:

getName in interface TypeNode

Returns:

The type node simple property name (without the path).

getType

public Class<?> getType()

Specified by:

getType in interface TypeNode

Returns:

The type of this type nodes matching property.

getFullName

public String getFullName()

Specified by:

getFullName in interface TypeNode

Returns:

The type node full name including that path to this this type nodes matching property.

getDynamicHeaderColumnName

protected String getDynamicHeaderColumnName()

Description copied from class: AbstractCompoundTypeNode

controls how this type will be read from cassandra, see implementations and SpaceDocumentTopLevelTypeNode. returning null will result by child property values being put in a HashMap

Specified by:

getDynamicHeaderColumnName in class AbstractCompoundTypeNode

Description copied from interface: TypeNode

Recursively read the value matching this type node property from the ColumnFamilyRow.

Specified by:

readFromColumnFamilyRow in interface TypeNode

Parameters:

row - The row to read from.
