Method Detail

getSymbolPosition

public static CurrencySymbolPosition getSymbolPosition(int value)

This method maps the currency symbol position from the representation used in the MPP file to the representation used by MPX.

Parameters:

value - MPP symbol position

Returns:

MPX symbol position

getDurationTimeUnits

public static final TimeUnit getDurationTimeUnits(int type)

This method converts between the duration units representation used in the MPP file, and the standard MPX duration units. If the supplied units are unrecognised, the units default to days.

Parameters:

type - MPP units

Returns:

MPX units

getAdjustedDuration

public static Duration getAdjustedDuration(ProjectFile file,
                                           int duration,
                                           TimeUnit timeUnit)

Given a duration and the time units for the duration extracted from an MPP file, this method creates a new Duration to represent the given duration. This instance has been adjusted to take into account the number of "hours per day" specified for the current project.

Parameters:

file - parent file

duration - duration length

timeUnit - duration units

Returns:

Duration instance

getDuration

public static final Duration getDuration(double value,
                                         TimeUnit type)

Reads a duration value. This method relies on the fact that the units of the duration have been specified elsewhere.

Parameters:

value - Duration value

type - type of units of the duration

Returns:

Duration instance

dumpRow

public static void dumpRow(Map<String,Object> row)

Dump the contents of a row from an MPD file.

Parameters:

row - row data

hexdump

public static final String hexdump(byte[] buffer,
                                   int offset,
                                   int length,
                                   boolean ascii)

This method generates a formatted version of the data contained in a byte array. The data is written both in hex, and as ASCII characters.

Parameters:

buffer - data to be displayed

offset - offset of start of data to be displayed

length - length of data to be displayed

ascii - flag indicating whether ASCII equivalent chars should also be displayed

Returns:

formatted string

hexdump

public static final String hexdump(byte[] buffer,
                                   boolean ascii)

This method generates a formatted version of the data contained in a byte array. The data is written both in hex, and as ASCII characters.

Parameters:

buffer - data to be displayed

ascii - flag indicating whether ASCII equivalent chars should also be displayed

Returns:

formatted string

hexdump

public static final String hexdump(byte[] buffer,
                                   boolean ascii,
                                   int columns,
                                   String prefix)

This method generates a formatted version of the data contained in a byte array. The data is written both in hex, and as ASCII characters. The data is organised into fixed width columns.

Parameters:

buffer - data to be displayed

ascii - flag indicating whether ASCII equivalent chars should also be displayed

columns - number of columns

prefix - prefix to be added before the start of the data

Returns:

formatted string

fileHexDump

public static final void fileHexDump(String fileName,
                                     byte[] data)

Writes a hex dump to a file for a large byte array.

Parameters:

fileName - output file name

data - target data

fileHexDump

public static final void fileHexDump(String fileName,
                                     InputStream is)

Writes a hex dump to a file from a POI input stream. Note that this assumes that the complete size of the data in the stream is returned by the available() method.

Parameters:

fileName - output file name

is - input stream

fileDump

public static final void fileDump(String fileName,
                                  byte[] data)

Writes a large byte array to a file.

Parameters:

fileName - output file name

data - target data
