| ObjectTable | | public class ObjectTable implements Serializable(Code) | | A lookup table for objects. This implementation is not synchronized, it is up
to the caller to synchronize it properly.

| Constructor Summary | |
| public | ObjectTable()
Creates a new table. | | public | ObjectTable(int increment)
Creates a new table. | | public | ObjectTable(int rowIncrement, int colIncrement)
Creates a new table. |
| Method Summary | |
| public void | clear()
Clears the table. | | protected void | copyColumn(int oldColumn, int newColumn)
Copys the contents of the old column to the new column. | | protected void | copyRow(int oldRow, int newRow)
Copys the contents of the old row to the new row. | | public void | ensureCapacity(int row, int column)
Ensures that there is storage capacity for the specified item. | | protected void | ensureRowCapacity(int row)
Checks that there is storage capacity for the specified row and resizes
if necessary. | | public boolean | equals(Object o)
Tests this paint table for equality with another object (typically also
an ObjectTable).
Parameters:
o - the other object. | | public int | getColumnCount()
Returns the number of columns in the table. | | public int | getColumnIncrement()
Returns the column size increment. | | protected Object[][] | getData()
| | protected Object | getObject(int row, int column)
Returns the object from a particular cell in the table. | | public int | getRowCount()
Returns the number of rows in the table. | | public int | getRowIncrement()
Returns the row size increment. | | public int | hashCode()
Returns a hash code value for the object. | | protected Object | readSerializedData(ObjectInputStream stream)
Handles the deserialization of a single element of the table.
Parameters:
stream - the object input stream from which to read the object. | | protected void | setData(Object[][] data, int colCount)
| | protected void | setObject(int row, int column, Object object)
Sets the object for a cell in the table. | | protected void | writeSerializedData(ObjectOutputStream stream, Object o)
Handles the serialization of an single element of this table. |
| ObjectTable | | public ObjectTable()(Code) | | Creates a new table.
|
| ObjectTable | | public ObjectTable(int increment)(Code) | | Creates a new table.
Parameters:
increment - the row and column size increment. |
| ObjectTable | | public ObjectTable(int rowIncrement, int colIncrement)(Code) | | Creates a new table.
Parameters:
rowIncrement - the row size increment.
Parameters:
colIncrement - the column size increment. |
| clear | | public void clear()(Code) | | Clears the table.
|
| copyColumn | | protected void copyColumn(int oldColumn, int newColumn)(Code) | | Copys the contents of the old column to the new column.
Parameters:
oldColumn - the index of the old (source) column
Parameters:
newColumn - the index of the new column |
| copyRow | | protected void copyRow(int oldRow, int newRow)(Code) | | Copys the contents of the old row to the new row. This uses raw access to
the data and is remarkably faster than manual copying.
Parameters:
oldRow - the index of the old row
Parameters:
newRow - the index of the new row |
| ensureCapacity | | public void ensureCapacity(int row, int column)(Code) | | Ensures that there is storage capacity for the specified item.
Parameters:
row - the row index.
Parameters:
column - the column index. |
| ensureRowCapacity | | protected void ensureRowCapacity(int row)(Code) | | Checks that there is storage capacity for the specified row and resizes
if necessary.
Parameters:
row - the row index. |
| equals | | public boolean equals(Object o)(Code) | | Tests this paint table for equality with another object (typically also
an ObjectTable).
Parameters:
o - the other object. A boolean. |
| getColumnCount | | public int getColumnCount()(Code) | | Returns the number of columns in the table.
The column count. |
| getColumnIncrement | | public int getColumnIncrement()(Code) | | Returns the column size increment.
the increment. |
| getObject | | protected Object getObject(int row, int column)(Code) | | Returns the object from a particular cell in the table. Returns null, if
there is no object at the given position.
Note: throws IndexOutOfBoundsException if row or column is negative.
Parameters:
row - the row index (zero-based).
Parameters:
column - the column index (zero-based). The object. |
| getRowCount | | public int getRowCount()(Code) | | Returns the number of rows in the table.
The row count. |
| getRowIncrement | | public int getRowIncrement()(Code) | | Returns the row size increment.
the increment. |
| hashCode | | public int hashCode()(Code) | | Returns a hash code value for the object.
the hashcode |
| setData | | protected void setData(Object[][] data, int colCount)(Code) | | |
| setObject | | protected void setObject(int row, int column, Object object)(Code) | | Sets the object for a cell in the table. The table is expanded if
necessary.
Parameters:
row - the row index (zero-based).
Parameters:
column - the column index (zero-based).
Parameters:
object - the object. |
| writeSerializedData | | protected void writeSerializedData(ObjectOutputStream stream, Object o) throws IOException(Code) | | Handles the serialization of an single element of this table.
Parameters:
stream - the stream which should write the object
Parameters:
o - the object that should be serialized
throws:
IOException - if an IO error occured |
