Removes the property from the underlying map.

Gets the current string value if any. Will not return null: use isSet to test for existence.

True if the key exists in the properties map. Note that this is not sufficient for a Boolean property to be considered true.

The full name of the property, e.g., "java.awt.headless".

Some(value) if the property is set, None otherwise.

Sets the property.

Sets the property with a value of the represented type.

The semantics of value are determined at Prop creation. See methods valueIsTrue and keyExists in object BooleanProp for examples.

A value of type T for use when the property is unset. The default implementation delivers null for reference types and 0/0.0/false for non-reference types.

Test two objects for inequality.

Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

Compares two Boolean expressions and returns true if both of them evaluate to true.

a & b returns true if and only if

• a and b are true.

Compares two Boolean expressions and returns true if both of them evaluate to true.

a && b returns true if and only if

• a and b are true.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

Compares two Boolean expressions and returns true if they evaluate to a different value.

a ^ b returns true if and only if

• a is true and b is false or
• a is false and b is true.

Cast the receiver object to be of type T0.

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

Create a copy of the receiver object.

The default implementation of the clone method is platform dependent.

Tests whether the argument (that) is a reference to the receiver object (this).

The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

• It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
• For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
• null.eq(null) returns true.

When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

The equality method for reference types. Default implementation delegates to eq.

See also equals in scala.Any.

Called by the garbage collector on the receiver object when there are no more references to the object.

The details of when and if the finalize method is invoked, as well as the interaction between finalize and non-local returns and exceptions, are all platform dependent.

Returns the runtime class representation of the object.

The hashCode method for reference types. See hashCode in scala.Any.

Test whether the dynamic type of the receiver object has the same erasure as T0.

Depending on what T0 is, the test is done in one of the below ways:

• T0 is a non-parameterized class type, e.g. BigDecimal: this method returns true if the value of the receiver object is a BigDecimal or a subtype of BigDecimal.
• T0 is a parameterized class type, e.g. List[Int]: this method returns true if the value of the receiver object is some List[X] for any X. For example, List(1, 2, 3).isInstanceOf[List[String]] will return true.
• T0 is some singleton type x.type or literal x: this method returns this.eq(x). For example, x.isInstanceOf[1] is equivalent to x.eq(1)
• T0 is an intersection X with Y or X & Y: this method is equivalent to x.isInstanceOf[X] && x.isInstanceOf[Y]
• T0 is a union X | Y: this method is equivalent to x.isInstanceOf[X] || x.isInstanceOf[Y]
• T0 is a type parameter or an abstract type member: this method is equivalent to isInstanceOf[U] where U is T0's upper bound, Any if T0 is unbounded. For example, x.isInstanceOf[A] where A is an unbounded type parameter will return true for any value of x.

This is exactly equivalent to the type pattern _: T0

Equivalent to !(this eq that).

Wakes up a single thread that is waiting on the receiver object's monitor.

Wakes up all threads that are waiting on the receiver object's monitor.

Executes the code in body with an exclusive lock on this.

Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

Negates a Boolean expression.

- !a results in false if and only if a evaluates to true and - !a results in true if and only if a evaluates to false.

Compares two Boolean expressions and returns true if one or both of them evaluate to true.

a | b returns true if and only if

• a is true or
• b is true or
• a and b are true.

Compares two Boolean expressions and returns true if one or both of them evaluate to true.

a || b returns true if and only if

• a is true or
• b is true or
• a and b are true.

Compares two Boolean expressions and returns true if they evaluate to a different value.

a != b returns true if and only if

• a is true and b is false or

Compares two Boolean expressions and returns true if they evaluate to the same value.

a == b returns true if and only if

Returns string formatted according to given format string. Format strings are as for String.format (@see java.lang.String.format).
