Method Detail
-
getRow
public int getRow()
- Returns:
- The row in which the component starts its display area.
-
getCol
public int getCol()
- Returns:
- The column in which the component starts its display area.
-
getColspan
public int getColspan()
- Returns:
- The number of cells in a row for the component's display area
or
REMAINDERif the component's display area will be from its grid position to the last cell in the row.
-
getRowspan
public int getRowspan()
- Returns:
- The number of cells in a column for the component's display area
or
REMAINDERif the component's display area will be from its grid position to the last cell in the column.
-
isPlaceholder
public boolean isPlaceholder()
- Returns:
- Whether this constraints object is a placeholder or not
-
equals
public boolean equals(java.lang.Object o)
Indicates whether some other object is "equal to" this one.The
equalsmethod implements an equivalence relation on non-null object references:- It is reflexive: for any non-null reference value
x,x.equals(x)returnstrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)returnstrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)returnstrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)returnsfalse.
The
equalsmethod for classExtendedGridLayoutConstraintsreturnstrueif and only if the constraints objects describe the sameComponent- Overrides:
equalsin classjava.lang.Object- Parameters:
o- the reference object with which to compare.- Returns:
trueif this object is the same as the o argument;falseotherwise.- See Also:
hashCode(),java.util.Hashtable
- It is reflexive: for any non-null reference value
-
hashCode
public int hashCode()
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided byjava.util.Hashtable.The general contract of
hashCodeis:- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals(Object)method, then calling thehashCodemethod on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
java.lang.Object#equals(java.lang.Object)method, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.
- Overrides:
hashCodein classjava.lang.Object- Returns:
- a hash code value for this object.

equals(java.lang.Object),java.util.Hashtable

an execution of a Java application, the
-
toString
public java.lang.String toString()
Returns a string representation of the object. In general, thetoStringmethod returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read.- Overrides:
toStringin classjava.lang.Object- Returns:
- a string representation of the object.
