Remarks

An interface that defines both lookup protocol and parsing of symbolic names.

This interface is used by UnicodeSet to resolve $Variable style references that appear in set patterns. RBBI and Transliteration both independently implement this interface.

A symbol table maintains two kinds of mappings. The first is between symbolic names and their values. For example, if the variable with the name "start" is set to the value "alpha" (perhaps, though not necessarily, through an expression such as "$start=alpha"), then the call lookup("start") will return the char[] array ['a', 'l', 'p', 'h', 'a'].

The second kind of mapping is between character values and UnicodeMatcher objects. This is used by RuleBasedTransliterator, which uses characters in the private use area to represent objects such as UnicodeSets. If U+E015 is mapped to the UnicodeSet [a-z], then lookupMatcher(0xE015) will return the UnicodeSet [a-z].

Finally, a symbol table defines parsing behavior for symbolic names. All symbolic names start with the SYMBOL_REF character. When a parser encounters this character, it calls parseReference() with the position immediately following the SYMBOL_REF. The symbol table parses the name, if there is one, and returns it.

Fields

SymbolRef

The character preceding a symbol reference name.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
Lookup(String)	Lookup the characters associated with this string and return it.
LookupMatcher(Int32)	Lookup the UnicodeMatcher associated with the given character, and return it.
ParseReference(String, ParsePosition, Int32)	Parse a symbol reference name from the given string, starting at the given position.
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
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.
TryJavaCast<TResult>(IJavaPeerable, TResult)	Try to coerce `self` to type `TResult`, checking that the coercion is valid on the Java side.
