Method Detail

public void accept(final ValueVisitor visitor) throws Exception

Implements abstract com.amazon.ion.impl.lite.IonValueLite.accept.

Implements com.amazon.ion.IonValue.accept.

Doc from com.amazon.ion.IonValue.accept.

Entry point for visitor pattern. Implementations of this method by concrete classes will simply call the appropriate visit method on the visitor. For example, instances of IonBool will invoke ValueVisitor#visit(IonBool).

Parameters
visitor:ValueVisitor

will have one of its visit methods called.

Annotations
@Override
Exceptions
Exception:
any exception thrown by the visitor is propagated.
cloneback to summary
public IonNullLite clone()

Implements abstract com.amazon.ion.impl.lite.IonValueLite.clone.

Implements com.amazon.ion.IonNull.clone, com.amazon.ion.IonValue.clone.

Doc from com.amazon.ion.IonValue.clone.

Creates a copy of this value and all of its children. The cloned value may use the same shared symbol tables, but it will have an independent local symbol table if necessary. The cloned value will be modifiable regardless of whether this instance isReadOnly().

The cloned value will be created in the context of the same ValueFactory as this instance; if you want a copy using a different factory, then use ValueFactory#clone(IonValue) instead.

Returns:IonNullLite

Doc from java.lang.Object.clone.

a clone of this instance.

public IonType getTypeSlow()

Returns:IonType

pack-priv int hashSignature()

Implements abstract com.amazon.ion.impl.lite.IonValueLite.hashSignature.

Returns:int

Doc from com.amazon.ion.impl.lite.IonValueLite.hashSignature.

the constant hash signature unique to the value's type.

@Override
scalarHashCodeback to summary
public int scalarHashCode()

Implements abstract com.amazon.ion.impl.lite.IonValueLite.scalarHashCode.

Doc from com.amazon.ion.impl.lite.IonValueLite.scalarHashCode.

Internal HashCode implementation to be overridden by scalar subclasses. Must only be called on non-null values.

Annotations

pack-priv IonValueLite shallowClone(IonContext context)

Implements abstract com.amazon.ion.impl.lite.IonValueLite.shallowClone.

Doc from com.amazon.ion.impl.lite.IonValueLite.shallowClone.

Clones the value's annotations and field name (if any). For scalars, also clones the value. For containers, leaves the cloned container empty rather than cloning the children.

Parameters
context:IonContext

the context applicable to the value's parent.

Returns:IonValueLite

a shallow clone of this value.

pack-priv final void writeBodyTo(IonWriter writer, _Private_IonValue.SymbolTableProvider symbolTableProvider) throws IOException

Implements abstract com.amazon.ion.impl.lite.IonValueLite.writeBodyTo.

Doc from com.amazon.ion.impl.lite.IonValueLite.writeBodyTo.

Writes a *non-null scalar* value to the given writer. It is incorrect to call this method on a container value.

Parameters
writer:IonWriter

an IonWriter.

symbolTableProvider:_Private_IonValue.SymbolTableProvider

a SymbolTableProvider.

Annotations
@Override
Exceptions
IOException:
if thrown when writing the value.
