Constructor Detail

EdgeLayoutDescriptor

public EdgeLayoutDescriptor()

Creates a new instance of an EdgeLayoutDescriptor using the default values.

Method Detail

setMinimumFirstSegmentLength

public void setMinimumFirstSegmentLength(double length)

Sets the minimum length of the first segment (at the source). Note: the resulting segment length also depends on the given grid size (see OrthogonalLayouter.setGrid(int)), i.e., segment length >= (int) Math.ceil(length / grid size).

Parameters:

length - the minimum length of the first segment

getMinimumFirstSegmentLength

public double getMinimumFirstSegmentLength()

Returns the minimum length of the first segment (at the source). Default is 15.0d.

Returns:

the length of the first segment

setMinimumLastSegmentLength

public void setMinimumLastSegmentLength(double length)

Sets the minimum length of the last segment (at the target). Note: the resulting segment length also depends on the given grid size (see OrthogonalLayouter.setGrid(int)), i.e., segment length >= (int) Math.ceil(length / grid size).

Parameters:

length - the minimum length of the last segment

getMinimumLastSegmentLength

public double getMinimumLastSegmentLength()

Returns the minimum length of the last segment (at the target). Default is 15.0d.

Returns:

the length of the last segment

setMinimumSegmentLength

public void setMinimumSegmentLength(double length)

Sets the minimum segment length of an edge. Note: the resulting segment length also depends on the given grid size (see OrthogonalLayouter.setGrid(int)), i.e., segment length >= (int) Math.ceil(length / grid size).

Parameters:

length - the minimum segment length.

getMinimumSegmentLength

public double getMinimumSegmentLength()

Returns the minimum segment length of the edge. Default is 15.0d.

Returns:

the minimum segment length of the edge

createCopy

public EdgeLayoutDescriptor createCopy()

Creates a copy of this instance.

Returns:

the copy.
