↳ | org.apache.xerces.util.SoftReferenceSymbolTable |
This symbol table uses SoftReferences to its String entries, which means that table entries that have no references to them can be garbage collected when memory is needed. Thus, in documents with very very large numbers of unique strings, using this SymbolTable will prevent an out of memory error from occuring.

initialCapacity | the initial capacity of the SymbolTable. |

loadFactor | the load factor of the SymbolTable. |
IllegalArgumentException | if the initial capacity is less than zero, or if the load factor is nonpositive. |

Constructs a new, empty SymbolTable with the specified initial capacity and default load factor, which is 0.75.
initialCapacity | the initial capacity of the hashtable. |

Constructs a new, empty SymbolTable with a default initial capacity (101) and load factor, which is 0.75.
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.
buffer | The buffer containing the new symbol. |
---|---|
offset | The offset into the buffer of the new symbol. |
length | The length of the new symbol in the buffer. |

Increases the capacity of and internally reorganizes this SymbolTable, in order to accommodate and access its entries more efficiently. This method is called automatically when the number of keys in the SymbolTable exceeds this hashtable's capacity and load factor.
