Constructs a shadow of the specified symbol table.

Method Detail

addSymbolback to summary
public String addSymbol(String symbol)

Overrides com.sun.org.apache.xerces.internal.util.SymbolTable.addSymbol.

Adds the specified symbol to the symbol table and returns a reference to the unique symbol. If the symbol already exists, the previous symbol reference is returned instead, in order guarantee that symbol references remain unique.

Parameters
symbol:String

The new symbol.

addSymbolback to summary
public String addSymbol(char[] buffer, int offset, int length)

Overrides com.sun.org.apache.xerces.internal.util.SymbolTable.addSymbol.

Adds the specified symbol to the symbol table and returns a reference to the unique symbol. If the symbol already exists, the previous symbol reference is returned instead, in order guarantee that symbol references remain unique.

Parameters
buffer:char[]

The buffer containing the new symbol.

offset:int

The offset into the buffer of the new symbol.

length:int

The length of the new symbol in the buffer.

hashback to summary
public int hash(String symbol)

Overrides com.sun.org.apache.xerces.internal.util.SymbolTable.hash.

Returns a hashcode value for the specified symbol. The value returned by this method must be identical to the value returned by the hash(char[],int,int) method when called with the character array that comprises the symbol string.

Parameters
symbol:String

The symbol to hash.

hashback to summary
public int hash(char[] buffer, int offset, int length)

Overrides com.sun.org.apache.xerces.internal.util.SymbolTable.hash.

Returns a hashcode value for the specified symbol information. The value returned by this method must be identical to the value returned by the hash(String) method when called with the string object created from the symbol information.

Parameters
buffer:char[]

The character buffer containing the symbol.

offset:int

The offset into the character buffer of the start of the symbol.

length:int

The length of the symbol.
