Method Detail

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.

lookup

public String lookup(char code)

This will perform a lookup into the map. Some characters (e.g. ligatures) decode to character sequences.

Parameters:

code - The code used to lookup.

Returns:

The string that matches the lookup.

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.

addMapping

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

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.

addCodespaceRange

public void addCodespaceRange(CodespaceRange range)

This will add a codespace range.

Parameters:

range - A single codespace range.

getCodeSpaceRanges

public List getCodeSpaceRanges()

Getter for property codeSpaceRanges.

Returns:

Value of property codeSpaceRanges.
