Adding property data

To change the value of property data for a particular vertex, use the property() step. Each property changed must have its own property() step.

  • If a property value has been dropped in order to change the value, a new value can be written. This example illustrates adding the value M to the author vertex with the name James Beard.

     g.V().has('author','name','James Beard').property('gender', 'M')
    gremlin> g.V().hasLabel('author').valueMap()
    ==>{gender=[F], name=[Julia Child]}
    ==>{gender=[F], name=[Patricia Curtan]}
    ==>{gender=[F], name=[Kelsie Kerr]}
    ==>{gender=[F], name=[Simone Beck]}
    ==>{gender=[F], name=[Alice Waters]}
    ==>{gender=[F], name=[Patricia Simon]}
    ==>{gender=[M], name=[James Beard]}
    ==>{name=[Fritz Streiff]}
    ==>{name=[Emeril Lagasse]}
    ==>{gender=[F], name=[Louisette Bertholie]}
