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

Implements com.amazon.ion.IonFloat.bigDecimalValue.

Doc from com.amazon.ion.IonFloat.bigDecimalValue.

Gets the value of this Ion float as a Java BigDecimal. This follows the behavior of BigDecimal#valueOf(double). It's recommended to call IonFloat#isNumericValue() before calling this method. If you need negative zeros, use doubleValue().

Returns:BigDecimal

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

Annotations
@Override
cloneback to summary
public IonFloatLite clone()

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

Implements com.amazon.ion.IonFloat.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:IonFloatLite

Doc from java.lang.Object.clone.

a clone of this instance.

Annotations
@Override
doubleValueback to summary
public double doubleValue() throws NullValueException

Implements com.amazon.ion.IonFloat.doubleValue.

Doc from com.amazon.ion.IonFloat.doubleValue.

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

Returns:double

the double value.

Exceptions
NullValueException:
if this.isNullValue().
floatValueback to summary
public float floatValue() throws NullValueException

Implements com.amazon.ion.IonFloat.floatValue.

Doc from com.amazon.ion.IonFloat.floatValue.

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

Returns:float

the float value.

Exceptions
NullValueException:
if this.isNullValue().
getTypeSlowback to summary
public IonType getTypeSlow()

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

Returns:IonType

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

the value's type.

Annotations
@Override
hashSignatureback to summary
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.

Annotations
@Override
isNumericValueback to summary
public boolean isNumericValue()

Implements com.amazon.ion.IonFloat.isNumericValue.

Doc from com.amazon.ion.IonFloat.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

a checked condition whether this value is numeric.

Annotations
@Override
scalarHashCodeback to summary
pack-priv 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
@Override
setValueback to summary
public void setValue(float value)

Implements com.amazon.ion.IonFloat.setValue.

Doc from com.amazon.ion.IonFloat.setValue.

Sets the value of this element.

setValueback to summary
public void setValue(double value)

Implements com.amazon.ion.IonFloat.setValue.

Doc from com.amazon.ion.IonFloat.setValue.

Sets the value of this element.

setValueback to summary
public void setValue(BigDecimal value)

Implements com.amazon.ion.IonFloat.setValue.

Doc from com.amazon.ion.IonFloat.setValue.

Sets the value of this element. Since Ion floats are essentially Java doubles, this performs a narrowing conversion as described by BigDecimal#doubleValue().

Parameters
value:BigDecimal

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

setValueback to summary
public void setValue(Double d)
shallowCloneback to summary
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.

Annotations

writeBodyToback to summary
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.
