Method Detail

path

public Path path()

Description copied from interface: Traverser

Get the current path of the traverser.

Specified by:

path in interface Traverser<T>

Overrides:

path in class AbstractTraverser<T>

Returns:

The path of the traverser

detach

public Traverser.Admin<T> detach()

Description copied from interface: Traverser.Admin

Prepare the traverser for migration across a JVM boundary.

Specified by:

detach in interface Traverser.Admin<T>

Overrides:

detach in class AbstractTraverser<T>

Returns:

The deflated traverser

split

public <R> Traverser.Admin<R> split(R r,
                                    Step<T,R> step)

Description copied from interface: Traverser.Admin

Generate a child traverser of the current traverser for current as step and new object location. The child has the path history, future, and loop information of the parent. The child extends that path history with the current as and provided R-object.

Specified by:

split in interface Traverser.Admin<T>

Overrides:

split in class O_OB_S_SE_SL_Traverser<T>

Type Parameters:

R - The current object type of the child

Parameters:

r - The current object of the child

step - The step yielding the split

Returns:

The split traverser

split

public Traverser.Admin<T> split()

Description copied from interface: Traverser.Admin

Generate a sibling traverser of the current traverser with a full copy of all state within the sibling.

Specified by:

split in interface Traverser.Admin<T>

Overrides:

split in class O_OB_S_SE_SL_Traverser<T>

Returns:

The split traverser

addLabels

public void addLabels(Set<String> labels)

Specified by:

addLabels in interface Traverser.Admin<T>

Overrides:

addLabels in class AbstractTraverser<T>

keepLabels

public void keepLabels(Set<String> labels)

Description copied from interface: Traverser.Admin

Drop all path information not associated with specified labels. This is an optimization method that allows a traverser to save memory and increase the likelihood of bulking.

Specified by:

keepLabels in interface Traverser.Admin<T>

Overrides:

keepLabels in class AbstractTraverser<T>

Parameters:

labels - the labels to keep path information for.

dropLabels

public void dropLabels(Set<String> labels)

Description copied from interface: Traverser.Admin

Drop all path information associated with specified labels. This is an optimization method that allows a traverser to save memory and increase the likelihood of bulking.

Specified by:

dropLabels in interface Traverser.Admin<T>

Overrides:

dropLabels in class AbstractTraverser<T>

Parameters:

labels - the labels to drop path information for.

dropPath

public void dropPath()

Description copied from interface: Traverser.Admin

Drop the path of the traverser. This is an optimization method that allows a traverser to save memory and increase the likelihood of bulking.

Specified by:

dropPath in interface Traverser.Admin<T>

Overrides:

dropPath in class AbstractTraverser<T>

hashCode

public int hashCode()

Overrides:

hashCode in class O_OB_S_SE_SL_Traverser<T>

equals

protected final boolean equals(LP_O_OB_P_S_SE_SL_Traverser other)

equals

public boolean equals(Object object)

Overrides:

equals in class O_OB_S_SE_SL_Traverser<T>
