Modifier and Type	Method and Description
public void	assignCurrentValue(Object Current value to assign for the current input context of this parser v) Overrides com.fasterxml.jackson.core.JsonParser.assignCurrentValue. Helper method, usually equivalent to: `getParsingContext().setCurrentValue(v);`
public boolean	canReadObjectId() Overrides com.fasterxml.jackson.core.JsonParser.canReadObjectId. Introspection method that may be called to see if the underlying data format supports some kind of Object Ids natively (many do not; for example, JSON doesn't).
public boolean	canReadTypeId() Overrides com.fasterxml.jackson.core.JsonParser.canReadTypeId. Introspection method that may be called to see if the underlying data format supports some kind of Type Ids natively (many do not; for example, JSON doesn't).

public void	close() Implements abstract com.fasterxml.jackson.core.JsonParser.close. Implements java.io.Closeable.close. Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature `Feature#AUTO_CLOSE_SOURCE` is enabled.
public JsonLocation	currentLocation() Overrides com.fasterxml.jackson.core.JsonParser.currentLocation. Method that returns location of the last processed input unit (character or byte) from the input; usually for error reporting purposes.
public String	currentName() Overrides com.fasterxml.jackson.core.JsonParser.currentName. Method that can be called to get the name associated with the current token: for `JsonToken#FIELD_NAME`s it will be the same as what `getText` returns; for field values it will be preceding field name; and for others (array values, root-level values) null.
public JsonToken	currentToken() Overrides com.fasterxml.jackson.core.JsonParser.currentToken. Accessor to find which token parser currently points to, if any; null will be returned if none.
