Method Detail

acceptback to summary
public void accept(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

Exceptions
Exception:
any exception thrown by the visitor is propagated.
bigDecimalValueback to summary
public BigDecimal bigDecimalValue() throws NullValueException

Implements com.amazon.ion.IonDecimal.bigDecimalValue.

Doc from com.amazon.ion.IonDecimal.bigDecimalValue.

Gets the value of this Ion decimal as a BigDecimal. If you need negative zeros, use decimalValue().

Returns:BigDecimal

the BigDecimal value, or null if this.isNullValue().

Annotations
@Override
cloneback to summary
public IonDecimalLite clone()

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

Implements com.amazon.ion.IonDecimal.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:IonDecimalLite

Doc from java.lang.Object.clone.

a clone of this instance.

public float floatValue() throws NullValueException

Implements com.amazon.ion.IonDecimal.floatValue.

Doc from com.amazon.ion.IonDecimal.floatValue.

Gets the value of this Ion decimal as a Java float value.

Implements com.amazon.ion.IonNumber.isNumericValue.

Doc from com.amazon.ion.IonNumber.isNumericValue.

Determines whether this value is numeric. Returns true if this value is none of null, nan, +inf, and -inf, and false if it is any of them.

Returns:boolean

pack-priv int scalarHashCode()

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

Sets the value of this element.

setValueback to summary
public void setValue(float value)

Implements com.amazon.ion.IonDecimal.setValue.

Doc from com.amazon.ion.IonDecimal.setValue.

Sets the value of this element. This method behaves like BigDecimal#valueOf(double) in that it uses the double's canonical string representation provided by Double#toString(double)}.

setValueback to summary
public void setValue(double value)

Implements com.amazon.ion.IonDecimal.setValue.

Doc from com.amazon.ion.IonDecimal.setValue.

Sets the value of this element. This method behaves like BigDecimal#valueOf(double) in that it uses the double's canonical string representation provided by Double#toString(double)}.

setValueback to summary
public void setValue(BigDecimal value)

Implements com.amazon.ion.IonDecimal.setValue.

Doc from com.amazon.ion.IonDecimal.setValue.

Sets the value of this element. To set a negative zero value, pass an Decimal.

Parameters
value:BigDecimal

the new value of this decimal; may be null to make this null.decimal.

pack-priv IonValueLite shallowClone(IonContext parentContext)

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
parentContext:IonContext

the context applicable to the value's parent.

Returns:IonValueLite

a shallow clone of this value.
