Constructor Detail

ObjectTable

public ObjectTable()

Creates a new table.

ObjectTable

public ObjectTable(int increment)

Creates a new table.

Parameters:

increment - the row and column size increment.

ObjectTable

public ObjectTable(int rowIncrement,
                   int colIncrement)

Creates a new table.

Parameters:

rowIncrement - the row size increment.

colIncrement - the column size increment.

Method Detail

getColumnIncrement

public int getColumnIncrement()

Returns the column size increment.

Returns:

the increment.

getRowIncrement

public int getRowIncrement()

Returns the row size increment.

Returns:

the increment.

ensureCapacity

public void ensureCapacity(int row,
                           int column)

Ensures that there is storage capacity for the specified item.

Parameters:

row - the row index.

column - the column index.

getRowCount

public int getRowCount()

Returns the number of rows in the table.

Returns:

The row count.

getColumnCount

public int getColumnCount()

Returns the number of columns in the table.

Returns:

The column count.

equals

public boolean equals(Object o)

Tests this paint table for equality with another object (typically also an ObjectTable).

Overrides:

equals in class Object

Parameters:

o - the other object.

Returns:

A boolean.

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class Object

Returns:

the hashcode

clear

public void clear()

Clears the table.

clearRow

public void clearRow(int row)

Clears the row by removing the array that stores the row-data. This reduces the in-memory size of the table at the cost of possibly having to recreate the row-data-array later.

Parameters:

row - the row to be deleted.
