Method Detail

symbols

public void symbols(SymbolTable symbols)

symbols reports the Symbol table that is being used for the decompression. This method should only be called when the Symbol table changes in the stream. For example, before and after an imported Node is enountered that uses a diffferent Symbol table.

Parameters:

symbols - The Symbol Table

dataBytes

public void dataBytes(byte[] data)

dataBytes sets the byte array for the definitions to follow. This method should only be called when the byte array object changes in the stream. For example, before and after an imported Node is encountered that uses a different byte array.

Parameters:

data - The Data

dataLocation

public void dataLocation(int pos,
                         int len)

dataLocation reports positional information for the Node to follow.

Parameters:

pos - The offset into the data for this Node

len - The length of this Node's definition

symbolID

public void symbolID(short symbolID)

symbolID reports the SymbolID for the Node to follow. Because Symbol IDs are specific to a Node type (Element, Entity, and Attribute) this value needs to be stored until the type of Node is reported.

Parameters:

symbolID - The Symbol ID
