Method Detail

prepare

public Term.NonTerminal prepare(java.lang.String keyspace,
                                ColumnSpecification receiver)
                         throws InvalidRequestException

Description copied from class: Term.Raw

This method validates this RawTerm is valid for provided column specification and "prepare" this RawTerm, returning the resulting prepared Term.

Specified by:

prepare in class Term.Raw

receiver - the "column" this RawTerm is supposed to be a value of. Note that the ColumnSpecification may not correspond to a real column in the case this RawTerm describe a list index or a map key, etc...

Returns:

the prepared term.

Throws:

InvalidRequestException

testAssignment

public AssignmentTestable.TestResult testAssignment(java.lang.String keyspace,
                                                    ColumnSpecification receiver)

Returns:

whether this object can be assigned to the provided receiver. We distinguish between 3 values: - EXACT_MATCH if this object is exactly of the type expected by the receiver - WEAKLY_ASSIGNABLE if this object is not exactly the expected type but is assignable nonetheless - NOT_ASSIGNABLE if it's not assignable Most caller should just call the isAssignable() method on the result, though functions have a use for testing "strong" equality to decide the most precise overload to pick when multiple could match.

getExactTypeIfKnown

public AbstractType<?> getExactTypeIfKnown(java.lang.String keyspace)

Description copied from class: Term.Raw

The type of the term if it can be infered.

Specified by:

getExactTypeIfKnown in class Term.Raw

Parameters:

keyspace - the keyspace on which the statement containing this term is on.

Returns:

the type of this Term if inferrable, or null otherwise (for instance, the type isn't inferable for a bind marker. Even for literals, the exact type is not inferrable since they are valid for many different types and so this will return null too).

getText

public java.lang.String getText()

Specified by:

getText in class Term.Raw

Returns:

a String representation of the raw term that can be used when reconstructing a CQL query string.

bindIndex

public int bindIndex()
