Class TwoArraysPathData

java.lang.Object

ej.microvg.image.pathdata.TwoArraysPathData

All Implemented Interfaces:

PathData

public class TwoArraysPathData
extends java.lang.Object
implements PathData

Decodes a path whose data is stored in two byte arrays: the commands and the commands' attributes. A command is encoded on one byte and the command's attributes are encoded in float.

Field Summary

Fields

Modifier and Type	Field and Description
static int	COMMAND_SIZE The number of bytes used to encode a command.
static int	PARAM_SIZE The number of bytes used to encode a command's attribute.

Constructor Summary

Constructors

Constructor and Description
TwoArraysPathData(java.nio.ByteBuffer commands, java.nio.ByteBuffer params) Creates a decoder that will decode the path encoded in two byte arrays.

Method Summary

Modifier and Type	Method and Description
boolean	hasRemainingCommand() Tells whether it remains at least one command to decode.
int	nextCommand() Gets next encoded command from path.
double	nextCoordinate() Gets next point coordinate from path.

Constructor Detail

TwoArraysPathData

public TwoArraysPathData(java.nio.ByteBuffer commands,
                         java.nio.ByteBuffer params)

Creates a decoder that will decode the path encoded in two byte arrays.

Parameters:

commands - the encoded path commands (the first available data is the first path's command)

params - the encoded commands' attributes (the first available data is the first command's attribute)

Method Detail

hasRemainingCommand

public boolean hasRemainingCommand()

Description copied from interface: PathData

Tells whether it remains at least one command to decode.

Specified by:

hasRemainingCommand in interface PathData

Returns:

true if, and only if, there is at least one command remaining in this path

nextCommand

public int nextCommand()

Description copied from interface: PathData

Gets next encoded command from path. The command will be decoded later thanks CommandDecoder.decodeCommand(int).

Specified by:

nextCommand in interface PathData

Returns:

the next command

nextCoordinate

public double nextCoordinate()

Description copied from interface: PathData

Gets next point coordinate from path.

Specified by:

nextCoordinate in interface PathData

Returns:

the next coordinate
