Method Detail

configure
public void configure(Object... keyValues)
Description copied from interface:Configuring
Accept a configuration to theStep
. Note that this interface extendsParameterizing
and so there is an expectation that theStep
implementation will have aParameters
instance that will house any values passed to this method. Storing these configurations inParameters
is not a requirement however, IF the configuration is an expected option for the step and can be stored on a member field that can be accessed on the step by more direct means (i.e. like a getter method).- Specified by:
configure
in interfaceConfiguring
-
getParameters
public Parameters getParameters()
Description copied from interface:Parameterizing
Gets the parameters on the step.- Specified by:
getParameters
in interfaceParameterizing
-
hashCode
public int hashCode()
- Overrides:
hashCode
in classAbstractStep<ComputerResult,ComputerResult>
-
toString
public String toString()
- Overrides:
toString
in classAbstractStep<ComputerResult,ComputerResult>
-
generateProgram
public ConnectedComponentVertexProgram generateProgram(Graph graph, Memory memory)
Description copied from interface:VertexComputing
Generate theVertexProgram
.- Specified by:
generateProgram
in interfaceVertexComputing
- Parameters:
graph
- theGraph
that the program will be executed over.memory
- theMemory
from the previous OLAP job if it exists, else its an empty memory structure.- Returns:
- the generated vertex program instance.
-
clone
public ConnectedComponentVertexProgramStep clone()
Description copied from interface:Step
Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication. When cloning a step, it is important that the steps, the cloned step is equivalent to the state of the step whenStep.reset()
is called. Moreover, the previous and next steps should be set toEmptyStep
.- Specified by:
clone
in interfaceStep<ComputerResult,ComputerResult>
- Overrides:
clone
in classAbstractStep<ComputerResult,ComputerResult>
- Returns:
- The cloned step
