public String exportAsString()
This method is equivalent to asCQLQuery()
but the output is formatted.
public String asCQLQuery()
This method returns a single 'CREATE FUNCTION' query corresponding to this function definition.
public KeyspaceMetadata getKeyspace()
public String getSignature()
This is the name of the function, followed by the names of the argument types between
parentheses, for example sum(int,int)
.
Note that the returned signature is not qualified with the keyspace name.
public String getSimpleName()
This is the name of the function, without arguments. Note that functions can be overloaded
with different argument lists, therefore the simple name may not be unique. For example, sum(int,int)
and sum(int,int,int)
both have the simple name sum
.
getSignature()
public Map<String,DataType> getArguments()
public String getBody()
public boolean isCalledOnNullInput()
This is true
if the function was created with CALLED ON NULL INPUT
, and
false
if it was created with RETURNS NULL ON NULL INPUT
.
