Constructors

Name	Description
Rational(Int32, Int32)	Create a `Rational` with a given numerator and denominator.

Properties

Name	Description
Class	Returns the runtime class of this `Object`. (Inherited from Object)
Denominator	Gets the denominator of the rational
Handle	The handle to the underlying Android instance. (Inherited from Object)
IsFinite	Indicates whether this rational represents a finite value.
IsInfinite	Indicates whether this rational represents an infinite value.
IsNaN	Indicates whether this rational is a <em>Not-a-Number (NaN)</em> value.
IsZero	Indicates whether this rational represents a zero value.
JniIdentityHashCode	Gets the identity hash code assigned to this Java peer by the interop runtime. (Inherited from Object)
JniManagedPeerState	Gets the state flags last assigned by the runtime. (Inherited from JavaObject)
JniPeerMembers	Gets the JNI metadata used to access members of this Java binding.
NaN	Constant for the <em>Not-a-Number (NaN)</em> value of the `Rational` type.
NegativeInfinity	Constant for the negative infinity value of the `Rational` type.
Numerator	Gets the numerator of the rational.
PeerReference	Gets the JNI object reference for this Java peer. (Inherited from Object)
PositiveInfinity	Constant for the positive infinity value of the `Rational` type.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code. (Inherited from Number)
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code. (Inherited from Number)
Zero	Constant for the zero value of the `Rational` type.

Methods

Name	Description
ByteValue()	Returns the value of the specified number as a `byte`. (Inherited from Number)
Clone()	Creates and returns a copy of this object. (Inherited from Object)
CompareTo(Rational)	Compare this rational to the specified rational to determine their natural order.
Construct(JniObjectReference, JniObjectReferenceOptions)	Delegates construction of this peer to the runtime's value manager. (Inherited from JavaObject)
Dispose()	Releases the resources held by this Java peer. (Inherited from Object)
Dispose(Boolean)	Releases the resources held by this Java peer. (Inherited from Object)
DisposeUnlessReferenced()	Asks the value manager to dispose this peer unless its mapping retains this same managed instance. (Inherited from JavaObject)
DoubleValue()	Returns the value of the specified number as a `double`.
Equals(Object)	Tests whether another managed peer refers to the same Java object. (Inherited from JavaObject)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
FloatValue()	Returns the value of the specified number as a `float`.
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
IntValue()	Returns the value of the specified number as a `int`.
JavaFinalize()	Obsolete. Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
LongValue()	Returns the value of the specified number as a `long`.
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
ParseRational(String)	Parses the specified string as a rational value.
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
SetPeerReference(JniObjectReference, JniObjectReferenceOptions)	Stores a reference value in the control block without creating a JNI reference copy. (Inherited from JavaObject)
ShortValue()	Returns the value of the specified number as a `short`. (Inherited from Number)
ToArray<T>()	Creates a managed array from this Java array wrapper. (Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
UnregisterFromRuntime()	Unregisters this Java peer from the interop runtime. (Inherited from Object)
Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)

Explicit Interface Implementations

Name	Description
IComparable.CompareTo(Object)	Compares this object with the specified object for order.
IJavaPeerable.Disposed()	Marks this peer as disposed and calls `Dispose` with `disposing` set to `true`. (Inherited from JavaObject)
IJavaPeerable.Finalized()	Marks this peer as disposed and calls `Dispose` with `disposing` set to `false`. (Inherited from JavaObject)
IJavaPeerable.JniObjectReferenceControlBlock	Gets the native control-block pointer used by this peer. (Inherited from JavaObject)
IJavaPeerable.SetJniIdentityHashCode(Int32)	Stores the identity hash code supplied by the runtime. (Inherited from JavaObject)
IJavaPeerable.SetJniManagedPeerState(JniManagedPeerStates)	Replaces the stored managed peer state flags. (Inherited from JavaObject)
IJavaPeerable.SetPeerReference(JniObjectReference)	Updates the peer reference and releases a disposed peer's control block when the reference is invalid. (Inherited from JavaObject)
IJavaPeerable.UnregisterFromRuntime()	Removes this instance from the runtime's Java object lookup.

Extension Methods

Name	Description
GetJniTypeName(IJavaPeerable)	Gets the JNI name of the type of the instance `self`.
JavaAs<TResult>(IJavaPeerable)	Try to coerce `self` to type `TResult`, checking that the coercion is valid on the Java side.
JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)	Reuses a compatible managed peer or obtains a wrapper of the requested type.
TryJavaCast<TResult>(IJavaPeerable, TResult)	Try to coerce `self` to type `TResult`, checking that the coercion is valid on the Java side.
