Constructor Detail

### CMap

    public CMap()

  Creates a new instance of CMap.

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 java.lang.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,
                           java.lang.String dest)
                    throws java.io.IOException

  This will add a mapping.

  Parameters:
    `src` - The src to the mapping.
    `dest` - The dest to the mapping.
  Throws:
    `java.io.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 java.util.List getCodeSpaceRanges()

  Getter for property codeSpaceRanges.

  Returns:
    Value of property codeSpaceRanges.
