Method Details

map

protected S map(Traverser.Admin<S> traverser)

Specified by:

map in class ScalarMapStep<S,S>

clone

public TailLocalStepPlaceholder<S> 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 when Step.reset() is called. Moreover, the previous and next steps should be set to EmptyStep.

Specified by:

clone in interface Step<S,S>

Overrides:

clone in class AbstractStep<S,S>

Returns:

The cloned step

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractStep<S,S>

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractStep<S,S>

getLimit

public Long getLimit()

Specified by:

getLimit in interface TailLocalStepContract<S>

getLimitAsGValue

public GValue<Long> getLimitAsGValue()

Specified by:

getLimitAsGValue in interface TailLocalStepContract<S>

asConcreteStep

public TailLocalStep<S> asConcreteStep()

Specified by:

asConcreteStep in interface GValueHolder<S,S>

isParameterized

public boolean isParameterized()

Specified by:

isParameterized in interface GValueHolder<S,S>

updateVariable

public void updateVariable(String name,
 Object value)

Specified by:

updateVariable in interface GValueHolder<S,S>

getGValues

public Collection<GValue<?>> getGValues()

Specified by:
