Constructor Detail

CMap

public CMap()

Creates a new instance of CMap.

Method Detail

addCodespaceRange

public void addCodespaceRange(CodespaceRange range)

This will add a codespace range.

Parameters: range A single codespace range.

addMapping

public void addMapping(byte[] src, String dest)

This will add a mapping.

Parameters: src The src to the mapping. dest The dest to the mapping.

Throws: IOException if the src is invalid.

getCodeSpaceRanges

public List getCodeSpaceRanges()

Getter for property codeSpaceRanges.

Returns: Value of property codeSpaceRanges.

hasOneByteMappings

public boolean hasOneByteMappings()

This will tell if this cmap has any one byte mappings.

Returns: true If there are any one byte mappings, false otherwise.

hasTwoByteMappings

public boolean hasTwoByteMappings()

This will tell if this cmap has any two byte mappings.

Returns: true If there are any two byte mappings, false otherwise.

isInCodeSpaceRanges

public boolean isInCodeSpaceRanges(byte[] code)

Check whether the given byte array is in codespace ranges or not.

Parameters: code The byte array to look for in the codespace range.

Returns: true if the given byte array is in the codespace range.

isInCodeSpaceRanges

public boolean isInCodeSpaceRanges(byte[] code, int offset, int length)

Check whether the given byte array is in codespace ranges or not.

Parameters: code The byte array to look for in the codespace range. offset The starting offset within the byte array. length The length of the part of the array.

Returns: true if the given byte array is in the codespace range.

lookup

public String lookup(byte[] code, int offset, int length)

This will perform a lookup into the map.

Parameters: code The code used to lookup. offset The offset into the byte array. length The length of the data we are getting.

Returns: The string that matches the lookup.

useCmap

public void useCmap(CMap cmap)

Implementation of the usecmap operator. This will copy all of the mappings from one cmap to another.

Parameters: cmap The cmap to load mappings from.
