Constructor Detail

RpfFileSections

public RpfFileSections()

RpfFileSections

public RpfFileSections(BinaryFile binFile)

Create the file sections object, and then go ahead and parse the file section section of the RPF file. Assumes, the file pointer is in the right place, at the Rpfheader.locationSectionLocation.

Parameters:

binFile - the binaryFile of the RPF frame file.

Method Detail

parse

public void parse(BinaryFile binFile)

getLocations

public RpfFileSections.RpfLocationRecord[] getLocations(int key)

getRpfLocationRecord

public RpfFileSections.RpfLocationRecord getRpfLocationRecord(int locationRecordId)

This function returns the location record, which provides the file location for a particular section. The LOC ids are in this file.

parseLocationSection

protected boolean parseLocationSection(BinaryFile binFile)

This function returns the RpfLocationSection for the file. Since we don't really know the location of the location section yet, we really have to have the file pointer set to the right place. This function should be called right after the RpfHeader has been read.

parseCoverageSection

public RpfFileSections.RpfCoverageSection parseCoverageSection(BinaryFile binFile)

Read the location and information about the coverage section. The method will find out where to start reading from inside the file.

parseAttributes

public RpfAttributes parseAttributes(BinaryFile binFile)

Read the location and information about the attribute section. The method will find out where to start reading from inside the file.

parseColorSection

public java.awt.Color[] parseColorSection(BinaryFile binFile,
                                          RpfColortable colortable)

This kicks back an array of OMColors, representing the colortable. By going through the RpfFileSections function, the file locations for the color sections are taken care of, and the RpfColortable.parseColorLookUpTable function is called correctly.
