Method Detail

getUsage

public String getUsage()

Description copied from interface: Parameterized

Human-readable format for the command-line usage string.

Specified by:

getUsage in interface Parameterized

Overrides:

getUsage in class ParameterizedBase

Returns:

command-line documentation string

configure

public void configure(org.apache.flink.api.java.utils.ParameterTool parameterTool)
               throws org.apache.flink.client.program.ProgramParametrizationException

Description copied from interface: Parameterized

Read parameter values from the command-line arguments.

Specified by:

configure in interface Parameterized

Overrides:

configure in class ParameterizedBase

Parameters:

parameterTool - parameter parser

Throws:

org.apache.flink.client.program.ProgramParametrizationException - when configuration is invalid

getIdentity

public String getIdentity()

Description copied from interface: Input

A human-readable identifier summarizing the input and configuration.

Returns:

the input identifier

vertexCount

protected long vertexCount()

Description copied from class: GeneratedGraph

The vertex count is verified to be no greater than the capacity of the selected data type. All vertices must be counted even if skipped or unused when generating graph edges.

Specified by:

vertexCount in class GeneratedGraph

Returns:

number of vertices configured for the graph

create

public org.apache.flink.graph.Graph<org.apache.flink.types.LongValue,org.apache.flink.types.NullValue,org.apache.flink.types.NullValue> create(org.apache.flink.api.java.ExecutionEnvironment env)

Description copied from interface: Input

Create the input Graph.

Parameters:

env - the ExecutionEnvironment

Returns:

the input Graph
