Method Detail

defaultPropertyCardinality

public Cardinality defaultPropertyCardinality(String key)

Specified by:

defaultPropertyCardinality in interface DefaultSchemaMaker

Returns:

the default cardinality of a property if created for the given key

makePropertyKey

public PropertyKey makePropertyKey(PropertyKeyMaker factory,
                                   Object value)

Description copied from interface: DefaultSchemaMaker

Creates a new property key with default settings against the provided PropertyKeyMaker and value.

Specified by:

makePropertyKey in interface DefaultSchemaMaker

Parameters:

factory - PropertyKeyMaker through which the property key is created

value - the value of the property. The default implementation does not use this parameter.

Returns:

A new property key

ignoreUndefinedQueryTypes

public boolean ignoreUndefinedQueryTypes()

Description copied from interface: DefaultSchemaMaker

Whether to ignore undefined types occurring in a query.

If this method returns true, then undefined types referred to in a JanusGraphVertexQuery will be silently ignored and an empty result set will be returned. If this method returns false, then usage of undefined types in queries results in an IllegalArgumentException.

Specified by:

ignoreUndefinedQueryTypes in interface DefaultSchemaMaker

determineClass

protected Class determineClass(Object value)
