Method Detail

equals

public boolean equals(Object obj)

equality method

Overrides:

equals in class Object

Parameters:

obj - an Object value

Returns:

a boolean value

See Also:

Object.hashCode(), HashMap

getDefault

public String getDefault()

Returns:

the default value, null if not set

getDescription

public String getDescription()

Returns:

the description of the element, or null if no description is available.

Since:

ant 1.6.1

getName

public String getName()

Returns:

the name of the attribute

hashCode

public int hashCode()

Description copied from class: Object

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons 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 the hashCode method 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 Object.equals(java.lang.Object) method, then calling the hashCode method 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 hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

isDoubleExpanding

public boolean isDoubleExpanding()

Determines whether RuntimeConfigurable.maybeConfigure(Project, boolean) will reevaluate this property. For compatibility reasons (#52621) it will, though for most applications (#42046) it should not.

Returns:

true if expanding twice (the default), false for just once

Since:

Ant 1.8.3

setDefault

public void setDefault(String defaultValue)

The default value to use if the parameter is not used in the templated instance.

Parameters:

defaultValue - the default value

setDescription

public void setDescription(String desc)

Parameters:

desc - Description of the element.

Since:

ant 1.6.1

setDoubleExpanding

public void setDoubleExpanding(boolean doubleExpanding)

See isDoubleExpanding() for explanation.

Parameters:

doubleExpanding - true to expand twice, false for just once

Since:

Ant 1.8.3

setName

public void setName(String name)

The name of the attribute.

Parameters:

name - the name of the attribute
