Doc from com.amazon.ion.IonReader.getFieldId.

/** Gets the symbol ID of the field name attached to the current value.

This is an "expert method": correct use requires deep understanding of the Ion binary format. You almost certainly don't want to use it.

hasNext back to summary

public boolean hasNext()

Implements com.amazon.ion.IonReader.hasNext.

Doc from com.amazon.ion.IonReader.hasNext.

Determines whether there is another value at the current depth; in other words whether there is a sibling value that may be reached using next(). This method may be called multiple times, which does not move the current position.

Warning

this method alters the internal state of the reader such that you cannot reliably get values from the "current" element. The only thing you should call after hasNext() is next()!

hasVersion	back to summary
pack-priv final boolean hasVersion()

intValue

back to summary

public int intValue()

Implements com.amazon.ion.IonReader.intValue.

Doc from com.amazon.ion.IonReader.intValue.

Returns the current value as an int. This is only valid if there is an underlying value and the value is of a numeric type (int, float, or decimal).

isInStruct

back to summary

public boolean isInStruct()

Implements com.amazon.ion.IonReader.isInStruct.

Doc from com.amazon.ion.IonReader.isInStruct.

Determines whether this reader is currently traversing the fields of an Ion struct. It returns false if the iteration is in a list, a sexp, or a datagram.

isNullValue back to summary

public boolean isNullValue()

Implements com.amazon.ion.IonReader.isNullValue.

Doc from com.amazon.ion.IonReader.isNullValue.

Determines whether the current value is a null Ion value of any type (for example, null or null.int). It should be called before calling getters that return value types (int, long, boolean, double).

iterateTypeAnnotations back to summary

public Iterator<String> iterateTypeAnnotations()

Implements com.amazon.ion.IonReader.iterateTypeAnnotations.

Doc from com.amazon.ion.IonReader.iterateTypeAnnotations.

Return the annotations on the curent value as an iterator. The iterator is empty (hasNext() returns false on the first call) if there are no annotations on the current value.

Implementations *may* throw UnknownSymbolException from this method if any annotation contains unknown text. Alternatively, implementations may provide an Iterator that throws UnknownSymbolException only when the user navigates the iterator to an annotation with unknown text.

Note

the iterator returned by this method is only valid while the reader remains positioned on the current value (i.e., before next, step in, or step out). Use cases that require storing a value's annotations after advancing past that value should either copy them from the iterator or call getTypeAnnotations().

Returns:Iterator<String>: not null.

loadStateData	back to summary
private final void loadStateData(int new_state)

longValue

back to summary

public long longValue()

Implements com.amazon.ion.IonReader.longValue.

newBytes back to summary

public byte[] newBytes()

Implements com.amazon.ion.IonReader.newBytes.

Doc from com.amazon.ion.IonReader.newBytes.

Returns the current value as a newly-allocated byte array. This is only valid when getType() returns IonType#BLOB or IonType#CLOB.

next back to summary

public IonType next()

Implements com.amazon.ion.IonReader.next.

this computes the actual move to the next state It does take into account the existence or absence of various properties, such as the symbol table name which is only present in some symbol tables. This also fills in a variety of current state variables that are used to return correct values by the "get" methods.

Returns:IonType

Doc from com.amazon.ion.IonReader.next.

stepIn back to summary

public void stepIn()

Implements com.amazon.ion.IonReader.stepIn.

Doc from com.amazon.ion.IonReader.stepIn.

Positions the reader just before the contents of the current value, which must be a container (list, sexp, or struct). There's no current value immediately after stepping in, so the next thing you'll want to do is call next() to move onto the first child value (or learn that there's not one).

Stepping into a null container (null.list, null.sexp, or null.struct) behaves as if the container were empty ([], (), or {}).

At any time stepOut() may be called to move the cursor back to (just after) the parent value, even if there's more children remaining.

stepOut back to summary

public void stepOut()

Implements com.amazon.ion.IonReader.stepOut.

Doc from com.amazon.ion.IonReader.stepOut.

Positions the iterator after the current parent's value, moving up one level in the data hierarchy. There's no current value immediately after stepping out, so the next thing you'll want to do is call next() to move onto the following value.

stringValue back to summary

public String stringValue()

Implements com.amazon.ion.IonReader.stringValue.

Doc from com.amazon.ion.IonReader.stringValue.

Returns the current value as a Java String. This is only valid when getType() returns IonType#STRING or IonType#SYMBOL.

symbolValue back to summary

public SymbolToken symbolValue()

Implements com.amazon.ion.IonReader.symbolValue.

Doc from com.amazon.ion.IonReader.symbolValue.

Returns the current value as a symbol token (text + ID). This is only valid when getType() returns IonType#SYMBOL.
