TextDirectionHeuristics Class

Definition

Some objects that implement TextDirectionHeuristic.

[Android.Runtime.Register("android/text/TextDirectionHeuristics", DoNotGenerateAcw=true)]

Attributes

Remarks

Some objects that implement TextDirectionHeuristic. Use these with the BidiFormatter#unicodeWrap unicodeWrap() methods in BidiFormatter. Also notice that these direction heuristics correspond to the same types of constants provided in the android.view.View class for android.view.View#setTextDirection setTextDirection(), such as android.view.View#TEXT_DIRECTION_RTL.

To support versions lower than android.os.Build.VERSION_CODES#JELLY_BEAN_MR2, you can use the support library's androidx.core.text.TextDirectionHeuristicsCompat class.

Constructors

Name Description
TextDirectionHeuristics()

Creates an instance; the predefined direction heuristics are static members.

TextDirectionHeuristics(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Name Description
AnyrtlLtr

If the text contains any strong right to left non-format character, determines that the direction is right to left, falling back to left to right if it finds none.

Class

Returns the runtime class of this Object.

(Inherited from Object)
FirststrongLtr

Determines the direction based on the first strong directional character, including bidi format chars, falling back to left to right if it finds none.

FirststrongRtl

Determines the direction based on the first strong directional character, including bidi format chars, falling back to right to left if it finds none.

Handle

The handle to the underlying Android instance.

(Inherited from Object)
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.

Locale

Force the paragraph direction to the Locale direction.

Ltr

Always decides that the direction is left to right.

PeerReference

Gets the JNI object reference for this Java peer.

(Inherited from Object)
Rtl

Always decides that the direction is right to left.

Methods

Name Description
Clone()

Creates and returns a copy of this object.

(Inherited from Object)
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)
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)
GetHashCode()

Returns a hash code value for the object.

(Inherited from Object)
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)
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)
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)
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
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)

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.
