Method Detail

supportsNullPropertyValues

public boolean supportsNullPropertyValues()

Description copied from interface: Graph.Features.VertexPropertyFeatures

Determines if meta-properties allow for null property values.

Specified by:

supportsNullPropertyValues in interface Graph.Features.VertexPropertyFeatures

supportsCustomIds

public boolean supportsCustomIds()

Description copied from interface: Graph.Features.VertexPropertyFeatures

Determines if an VertexProperty has a specific custom object as their internal representation.

Specified by:

supportsCustomIds in interface Graph.Features.VertexPropertyFeatures

willAllowId

public boolean willAllowId(Object id)

Description copied from interface: Graph.Features.VertexPropertyFeatures

Determines if an identifier will be accepted by the Graph. This check is different than what identifier internally supports as defined in methods like Graph.Features.VertexPropertyFeatures.supportsNumericIds(). Those refer to internal representation of the identifier. A Graph may accept an identifier that is not of those types and internally transform it to a native representation.

Note that this method only applies if Graph.Features.VertexPropertyFeatures.supportsUserSuppliedIds() is true. Those that return false for that method can immediately return false for this one as it allows no ids of any type (it generates them all).

The default implementation will immediately return false if Graph.Features.VertexPropertyFeatures.supportsUserSuppliedIds() is false. If custom identifiers are supported then it will throw an exception. Those that return true for Graph.Features.VertexPropertyFeatures.supportsCustomIds() should override this method. If Graph.Features.VertexPropertyFeatures.supportsAnyIds() is true then the identifier will immediately be allowed. Finally, if any of the other types are supported, they will be typed checked against the class of the supplied identifier.
