org.apache.commons.geometry.io.euclidean.threed.BoundaryIOManager3D

public class BoundaryIOManager3D
extends BoundaryIOManager<PlaneConvexSubset,BoundarySource3D,BoundaryReadHandler3D,BoundaryWriteHandler3D>

Class managing IO operations for geometric data formats containing 3D region boundaries. IO operation are performed by read and write handlers registered for specific data formats.

Implementation note:Instances of this class are thread-safe as long as the registered handler instances are thread-safe.

Method Details

facetDefinitionReader

public FacetDefinitionReader facetDefinitionReader(GeometryInput in,
 GeometryFormat fmt)

Get a FacetDefinitionReader for reading facet information from the given input.

Parameters:

in - input to read facets from

fmt - format of the input; if null, the format is determined implicitly from the file extension of the input file name

Returns:

facet definition reader

Throws:

IllegalArgumentException - if no read handler can be found for the input format

IllegalStateException - if a data format error occurs

UncheckedIOException - if an I/O error occurs

facets

public Stream<FacetDefinition> facets(GeometryInput in,
 GeometryFormat fmt)

Return a Stream providing access to all facets from the given input. The underlying input stream is closed when the returned stream is closed. Callers should therefore use the returned stream in a try-with-resources statement to ensure that all resources are properly released.

  try (Stream<FacetDefinition> stream = manager.facets(in, fmt)) {
      // access stream content
  }
 

The following exceptions may be thrown during stream iteration:

• IllegalStateException if a data format error occurs
• UncheckedIOException if an I/O error occurs

Parameters:

in - input to read from

fmt - format of the input; if null, the format is determined implicitly from the file extension of the input file name

Returns:

stream providing access to the facets in the input

Throws:

IllegalArgumentException - if no read handler can be found for the input format

IllegalStateException - if a data format error occurs during stream creation

UncheckedIOException - if an I/O error occurs during stream creation

triangles

public Stream<Triangle3D> triangles(GeometryInput in,
 GeometryFormat fmt,
 org.apache.commons.numbers.core.Precision.DoubleEquivalence precision)

Return a Stream providing access to all triangles from the given input. The underlying input stream is closed when the returned stream is closed. Callers should therefore use the returned stream in a try-with-resources statement to ensure that all resources are properly released.

  try (Stream<Triangle3D> stream = manager.triangles(in, fmt, precision)) {
      // access stream content
  }
 

The following exceptions may be thrown during stream iteration:

• IllegalArgumentException if mathematically invalid data is encountered
• IllegalStateException if a data format error occurs
• UncheckedIOException if an I/O error occurs

Parameters:

in - input to read from

fmt - format of the input; if null, the format is determined implicitly from the file extension of the input file name

precision - precision context used for floating point comparisons

Returns:

stream providing access to the triangles in the input

Throws:

IllegalArgumentException - if no read handler can be found for the input format

IllegalStateException - if a data format error occurs during stream creation

UncheckedIOException - if an I/O error occurs during stream creation

readTriangleMesh

public TriangleMesh readTriangleMesh(GeometryInput in,
 GeometryFormat fmt,
 org.apache.commons.numbers.core.Precision.DoubleEquivalence precision)

Return a TriangleMesh containing all triangles from the given input.

Parameters:

in - input to read from

fmt - format of the input; if null, the format is determined implicitly from the file extension of the input file name

precision - precision context used for floating point comparisons

Returns:

mesh containing all triangles from the input

Throws:

IllegalArgumentException - if mathematically invalid data is encountered or no read handler can be found for the input format

IllegalStateException - if a data format error occurs

UncheckedIOException - if an I/O error occurs

write

public void write(Stream<? extends PlaneConvexSubset> boundaries,
 GeometryOutput out,
 GeometryFormat fmt)

Write all boundaries in the stream to the output.

This method does not explicitly close the boundaries stream. If callers need to ensure that the stream is closed (for example, if the stream is reading from a file), they should use it in a try-with-resources statement outside of this method.

Parameters:

boundaries - stream containing boundaries to write

out - output to write to

fmt - format of the output; if null, the format is determined implicitly from the file extension of the output file name

Throws:

IllegalArgumentException - if no write handler can be found for the output format

UncheckedIOException - if an I/O error occurs

writeFacets

public void writeFacets(Stream<? extends FacetDefinition> facets,
 GeometryOutput out,
 GeometryFormat fmt)

Write all facet in the stream to the output.

This method does not explicitly close the boundaries stream. If callers need to ensure that the stream is closed (for example, if the stream is reading from a file), they should use it in a try-with-resources statement outside of this method.

Parameters:

facets - stream containing facets to write

out - output to write to

fmt - format of the output; if null, the format is determined implicitly from the file extension of the output file name

Throws:

IllegalArgumentException - if no write handler can be found for the output format

UncheckedIOException - if an I/O error occurs

writeFacets

public void writeFacets(Collection<? extends FacetDefinition> facets,
 GeometryOutput out,
 GeometryFormat fmt)

Write the given facets to the output.

Parameters:

facets - facets to write

out - output to write to

fmt - format of the output; if null, the format is determined implicitly from the file extension of the output file name

Throws:

IllegalArgumentException - if no write handler can be found for the output format

UncheckedIOException - if an I/O error occurs

registerDefaultHandlers

public void registerDefaultHandlers()

Register default read/write handlers. This method registers a read and write handler for each value in GeometryFormat3D.
