Method Detail

read

public static PgJvxSrc[] read(java.lang.String fileName)

Read geometry from file in JavaView JVX format.

Alternatively, one may call load(BuffereredReader) followed by getGeometries() resp. getAnimations() to have a finer control about which information one wants to use from a source. For example, optional display information must be retrieve by a subsequent call getDisplayOption() if available.

Parameters:

fileName - File or URL to read data from.

Author:

Konrad Polthier

Version:

03.03.03, 1.10 revised (kp) No longer match case when comparing name with "object_".
12.12.00, 1.00 created (kp)

read

public PgJvxSrc[] read(java.io.BufferedReader in)

Read XML file and fill a new PsJvxSrc class.

Alternatively, one may call load(BuffereredReader) followed by getGeometries() resp. getAnimations() to have a finer control about which information one wants to use from a source. For example, optional display information must be retrieve by a subsequent call getDisplayOption() if available.

Specified by:

read in interface PgLoaderIf

Overrides:

read in class PgAbstractLoader

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

PgAbstractLoader.write(Writer, PgJvxSrc [])

Author:

Konrad Polthier

Version:

16.04.00, 1.10 revised (kp) Return type changed from PsXmlNode to PsXmlsrc.
16.01.00, 1.00 created (kp)

write

public boolean write(java.io.Writer writer,
                     PgJvxSrc[] geom)

Write all geometries in a XML tree structure of instances of type PsXmlNode and into a writer.

Specified by:

write in interface PgLoaderIf

Overrides:

write in class PgAbstractLoader

Parameters:

writer - Write all data to this stream

geom - Array with geometries to save

Returns:

true on success.

See Also:

write(PgJvxSrc [])

18.02.01, 1.00 created (kp)

write

public java.lang.String write(PgJvxSrc[] geom)

Write all geometries in a XML tree structure of instances of type PsXmlNode and create a XML formatted string.

Parameters:

geom - Array with geometries to save

Returns:

formatted string of xml tree.

See Also:

write(Writer, PgJvxSrc [])

parseFunList

public static java.lang.String[][] parseFunList(PsXmlNode parentNode,
                                                java.lang.String type,
                                                java.lang.String[] attr)

Parse an array of PsXmlNodes of same element type, where each element has data consisting of a blank separated list of functions to be interpreted.

Parameters:

parentNode - parent node containing a set of color nodes as children

type - type of elements in array

attr - array of attributes the vector might have, may be null.

Returns:

parsed string array, or null if failed

Version:

20.05.01, 1.10 revised (kp) Moved to PgJvxLoader from PsXmlLoader.
